Renson HealthBox® DCV System

Renson HealthBox DCV System

The Healthbox® II monitors the indoor air quality, focussing on: moisture and/or VOC and CO2 24 hours a day, even when the occupants are not at home. The built-in sensor in the control module will regulate the control flap to extract the right amount of air from the room to provide the best air quality with the best energy-efficiency. The Healthbox® II has up to 6 separate connections to enable energy-efficient ventilation. Now also available with 8 connections (Healthbox® Smartzone).

The Healthbox® II screens moisture and/or CO2 in each connected room 24 hours a day, even when the occupants are not at home. The built-in sensor in the control module will open the control flap to a greater or lesser degree. The Healthbox® II has up to 6 separate connections to enable energy-efficient ventilation.

Driver Renewables Design vents for extraction in Kerry, Cork and Limerick

To enable the integration of the extraction vents into the ceiling, the location of the control system was shifted from the extraction vent to the electronic control modules on the motor unit.

In addition, the plastic extraction vents were replaced by aluminium design vents. These design vents (height 11mm) were developed for integration or mounting into or onto the ceiling (or wall), for a plaster, plasterboard or a MDF base surface. These vents are generally supplied in RAL 9010 matt (white) but can easily be painted over. The occupant can choose between 6 different designs, so that combinations with all kinds of décors are possible.

The vents are generally equipped with an 80 mm diameter connection, while only for the kitchen, this standard diameter is 125 mm.

Unique automatic calibration system

The entire system is automatically calibrated, achieving the appropriate flow rate for each control module, regardless of the length and type of the ducting. The control modules can be programmed according to the type of room and/or standard, which is to say, one can indicate at the time of installation, whether the room in question is a wet or dry room. The control modules will then be set to the required maximum flow rate per room and will communicate with the motor unit in order to determine the required total flow rate of all wet and dry rooms, specifically for that house.

This avoids the risk of possible errors during settings and is a major time saver. The total adjustment time will be limited to an average of 12 minutes.

Energy savings through optimised, extraction, on-demand

The Healthbox® II has a powerful motor with control modules that can ensure proper ventilation of any connected room at all times. A humidity and/or CO2 sensor in each control module measures the extraction air 24 hours a day, and communicates with the central processor. The control module limits the extraction rate per room if possible and also runs the motor at a lower speed.

The Healthbox® II thereby achieves heat savings and savings in electricity consumption.

4-position button (XVK4)

The four-position switch is a wired button that provides feedback about the status of the ventilation group via blue LEDs. The button allows us to make a selection from 4 programs.

Mechanical Ventilation Systems With Heat Recovery (MVHR)

Mechanical Ventilation With Heat Recovery (MVHR)

Mechanical Ventilation with Heat Recovery is an energy efficient ventilation and heating solution suitable for both new and retrofit properties (addition of new technology or features to older systems).

MVHR systems perform three main functions. It supply’s fresh filtered air to the living areas such as bedrooms, dining rooms, living rooms etc. while also extracting the humid, stale from wet room such as the kitchen, utility and bathrooms. Before exhausting this stale air, it extracts the heat from it. After all you have already spent money heating it. This heat is then transferred to the fresh air and distributed throughout the house.

Benefits Of MVHR Systems Ensure excellent indoor air quality

  • Protects against mould & condensation issues within the property
  • Recovers up to 98% of heat typically lost with passive systems
  • Clinically proven to help sufferers of asthma and other respiratory problems
  • No trickle vents or bathroom fans required.
  • Allow occupant to ventilate property securely without having to open doors or windows.
  • Quiet and draught free
  • Removes unwanted cooking smells and other odours.
  • Helps prevent build-up of potentially lethal radon gas
  • MVHR systems are environmentally friendly and are a recommended in Part F of Irish TGD.

Features To Look For In MVHR Systems

The standard of modern MVHR system is extremely high. The features of the high performing MVHR systems recommended  include;

  • Greater than 90% efficiency
  • High Efficiency EC Fans
  • Counter Flow Polystyrene Heat Exchangers
  • Automatic Summer Bypass
  • Built in Humidity Detection
  • Frost Protection
  • Digital Controller
  • Extended Warranty

Introducing Demand Controlled Ventilation

Demand Controlled Ventilation is a controlled method of ventilating your home that links the amount of fresh air supplied to the occupancy of the home. DCV systems continuously monitor indoor air quality measuring parameters such humidity (H2O), carbon dioxide (CO2) and Volatile Organic Compounds (VOCs) which are harmful to our health. As these levels fluctuate daily so too does the DCV system ensuring that the flow rates are sufficient when levels are high. The system runs in trickle mode when air quality is good. This ensures optimum ventilation throughout the home using the minimum energy to do so.

Fitting A DCV System

A demand controlled fan unit is installed in the attic/ utility or plant room. A separate duct is installed from the fan unit to the wet rooms such as the kitchen, utility, bathrooms & WCs. Sensors, fitted inline in the duct, or in the room, depending on the brand used, measure air quality in each area. Based on these readings, humid or stale air is extracted from the wet areas and fresh air is drawn into to the house through wall or window vents strategically positioned in each habitable area such as bedrooms, living rooms etc.

Benefits Of DCV

  • DCV systems are demand controlled meaning each room is ventilated at the optimum level.
  • DCV systems are significantly more cost effective to run versus other ventilation systems using as little as .2 to .5 w/l/s. This translates to running costs of less than €50 p/year.
  • DCV systems are automatic and as such demand no user interaction Ensures no mould/ condensation issues throughout the property.
  • DCV systems are suitable for new and existing buildings.
  • DCV systems are very quiet when operating, running at approx. 25-30db.
  • DCV systems do not require filters.
  • DCV systems ensure optimal security as occupants do not need to open windows for ventilation purposes.

Multiple System air conditioners available

All split systems are quieter, more powerful and energy efficient than window/wall and portable air conditioners. Many split system air conditioners also come with handy built in features such as motion sensors, Wi-Fi and air purifiers or ionisers.

Single vs multi split system air conditioning

Both single and multi split system air conditioners have inside and outside units. A single split system air conditioner has one inside unit, whereas a multi split system can have multiple indoor units all connected to the one outdoor unit. Both single and multi split units are available as heating and cooling, or cooling only air outlet models.

A multi split system generally allows you to have up to five or more separate indoor units for different rooms in your house. The outdoor unit can be wall mounted if you live in a unit or have a multistorey house. Multi split systems are well suited for both residential and commercial use.

Multi split system air conditioning vs ducted air conditioning

If you need air conditioning in more than one room or area of your home but don’t have room to install ducted air conditioning then a multi split system is a great alternative.

Flexibility and convenience

Multi split system air conditioners offer unreal flexibility and convenience allowing you to choose the right indoor unit for each room of your house. You can install a high capacity air conditioner for larger living rooms and smaller, quieter ones for the bedrooms, all powered by the one outside unit. This allows you to control the temperature and environment in your home on room by room basis.

Being able to individually adjust the temperatures in each room you’ll save money and have maximum comfort by heating or cooling individual rooms. You can have up to five separate indoor air outlets all powered by a single outside compressor.

Energy efficiency

Energy saving settings combined with the ability to heat or cool individual rooms helps to reduce power and running costs. Choosing the right indoor air outlet unit to suit each room also ensures that you’re not wasting power. The wrong unit in a room can result in the air not being cooled properly and energy being wasted. A unit that’s too big for a smaller room also uses more power every time you turn it on compared to a smaller unit running for a longer period of time.

By operating multiple indoor air conditioners from the one external air compressor, multi split system air conditioners are among the most energy efficient of all air conditioners. Choose the most energy efficient inside air outlet units for maximum savings on your bill.

Pros of a multi split system air conditioner

There are many great reasons to consider a multi split air conditioner to keep your home cool in summer and warm in winter. These include:

  • energy efficiency
  • multiple indoor air outlets powered by the one outside compressor unit
  • ability to choose the most suitable and energy efficient air outlet unit on a room by room basis
  • adjusting temperatures to suit each room
  • more affordable to purchase and install compared to ducted air conditioning
  • you can add in extra air outlets later on down the track if needed
  • affordable maintenance, service, repairs and replacement of units.

Cons of a multi split system air conditioner

If you’re considering installing multi split system air condition you should also take the following into consideration:

  • Outdoor air unit need to be placed as close as possible to the indoor air outlet.

Multisplit system has a structure similar to the splits, with the difference that a single outdoor unit is connected to several indoor units that can be placed in different rooms. The work of this type of air conditioner can be controlled by pilots – each internal part of the evaporator has a separate remote control. Multisplit’s biggest advantage is, that only one unit is required to support multiple indoor units.

Underfloor Heating

Underfloor heating are a very clean and simple form of heating, ideally suited to today’s well-insulated, low-energy and airtight buildings in Cork, Limerick and Kerry.

Why would you choose underfloor heating?

Comfort: The most compelling reason to choose underfloor heating is comfort. Radiation, like the heat we get from the sun, is the most natural and comfortable form of heating. Research has shown that people feel more comfortable when they experience warm feet and a cold head. An underfloor heating system produces these conditions naturally, there are no localised hotspots, just a gentle feeling of warmth throughout your home.

Energy Efficient & Cost-Effective: The underfloor heating system uses radiant heat most people find they are comfortable at temperature settings several degrees lower than with other conventional heating systems. Lower your thermostat setting while enjoying the same level of comfort and reducing your heating bills by anything up to 40%. Underfloor heating is energy efficient and cost effective in any building commercial or domestic.

Underfloor Heating Pipe Matrix

How Underfloor Heating Works

Your water (25-40°C) is circulated through a series of polyethylene piping installed and integrated within the floor make-up. The pipe is then connected to a centrally located unit. The temperature of each room can be individually controlled as required via room thermostat. Each room thermostat can be set at 2°C lower than a room heated by radiators.

This is because underfloor heating delivers 70% radiant heat and 30% convection heat as opposed to radiators, which emit 30% radiant heat and 70% convection heat. This means that an underfloor heating system is a more efficient way of heating your home. Each room can be controlled by a programmable room thermostat allowing each room to have time and temperature control, when any one of these thermostats call for heat they open an electronically operated valve (actuator) that is fitted to the top body of the manifold, this would then turn your pump on and fire up your heat source. Each loop on the manifold is capable of having its own control typically one loop per room.

Radiators distribute heat by convection currents, which can result in draughts and hot spots. Radiators transfer heat into a room largely by convection from a hot metal surface. Because the surface of the radiator is small, in comparison to the volume of the room, it needs a high heat input and doesn’t spread the heat evenly. Convection currents circulate allergens, dust particles, fumes and germs which are then distributed around the building, contributing to an unhealthy atmosphere.

Underfloor Heating is easy to install, requires low maintenance and is very cost effective to run. The room is heated mostly by radiation, like the heat we get from the sun, the most natural and comfortable form of heating. An underfloor heating system creates an even temperature, comfortable environment with no hot or cold draughts, just a gentle feeling of warmth throughout your home. Rooms with high ceilings such as churches, sports halls or industrial units gain even greater benefits. With radiator systems, some of the heat is immediately wasted as it rises to the ceiling. With an underfloor heating system, the heat is concentrated at floor level where it is most needed. In rooms with large areas, underfloor heating is the only way to heat the centre of the floor area effectively.

Underfloor Heating systems goes hand in hand with heat pump installations

An underfloor system heating circulates low temperature water. Most conventional heating systems circulate warm water, usually between 50ºC to 80ºC whereas an underfloor heating system circulates water between 25ºC to 40ºC. A heat pump is most efficient when heating water at lower temperatures, the heat pump efficiency goes up bringing your running cost down.

Main features & benefits

Underfloor Heating also referred to as geothermal heating have become a firm favorite for those undertaking new build projects and the benefits are clear:

Comfort: Since radiant heat is the most natural and comfortable form of heating. An underfloor heating system will provide true comfort levels, giving a gentle feeling of warmth throughout your home.

Saves you money on energy bills: With underfloor heating the thermostat of each room can be set at 2°C lower than a room heated by radiators. You can save up to 30% on your heating bills.

Perfect working with heat pumps: Underfloor heating goes hand in hand with heat pump installations. An underfloor heating system circulates low temperature water. A heat pump is most efficient when heating water at low temperatures.

Invisible: No radiators, you are free to position your furniture however you would like in your home.

Health and Hygiene: An underfloor heating system reduces the circulation of airborne pollutants. It also helps to reduce house dust mites as the moisture content is too low to allow dust mites to live. This is great news for anyone with allergies or asthma.

Increased Humidity: With underfloor heating the heat comes from hot water, this also introduces moisture into the air and can reduce health problems caused by air which is extremely dry.

Safety: The hidden heating elements of an underfloor heating system is also a safety bonus since you no longer need to worry about children burning or tripping.

Exhaust Hot Water Heat Pumps

Exhaust Air Heat Pumps

The benefits of exhaust air heat pump are numerous?

Buildings must be ventilated

  • An all-in-one units – Heat-recovery ventilation, Heating & Hot water.
  • Ideal for smaller new homes or Passive House that will be at a high level of air-tightness and low heat loss
  • Usually less cost than buying separate traditional solutions and a stand-alone heat recovery unit.
  • Good solution for multiple small dwellings such as apartments, more cost effective than district heating, more environmentally friendly than multiple gas boilers etc
  • We have a choice of different models to suit different requirements
  • Connects easily to Solar Thermal – in fact the on-board controls of all our heat pumps can control solar thermal systems.
  • Works well with a room sealed stove (separate air supply for combustion)
  • Possible to dock with a Nibe EAHP with a gas boiler as back up for extreme weather

If the building will be more than 150SQ M, or has a total heat loss of more than 2-3 kW then consider one of our ground source or air to water units with an integral ventilation module .

For air-tight, low energy builds, where ventilation is a must, choose an Exhaust Air Heat-Pump. This will re-cycle the heat from your house’s ventilation system. These machines are ideal for apartments and more compact air-tight low energy or passive homes. Air is drawn through ducts to the heat pump from the bathrooms, utility and kitchen areas. The cold waste air is discharged to outside through another duct, and condensation to a drain.
Not only that, the additional heat generated internally from lighting,
people and domestic appliances is also used through heat recovery.

On Demand Control Ventilation Systems

Driver Renweables supply and install of DCV Equipment in Cork, Limerick and Kerry. (DCV) is a method of providing automatic regulation to the ventilation system depending on the requirements of the building and upon the needs of air change rates number of occupancy, pollution loads, general environmental factors. Demand Control Ventilation a suitable sensor and without user intervention.

Sustainable Energy
This approach can be applied to any of the system types above and has been very popular in Europe for decades. Demand Control is now a common feature of quality s continuous mechanical extract ventilation and passive stack ventilation systems.

Our Demand Control Ventilation systems, extract and supply air flow rates. These can be regulated to ventilate where and when needed, achieving an overall reduction in air renewal and associated heat losses.

Recent studies carried out in Europe demonstrate that DCV results in at least 30% reduction in ventilation losses compared to natural ventilation with conventional extract fans. It can also reduce the primary energy use of associated fans.

Extensive monitoring also shows that demand-controlled mechanical extract ventilation achieves excellent indoor air quality leaving your house fresh all day.

Benefits of DCV

  •  Low electrical running costs (from 0.27-0.5 W/l/s).
  •  No filter changes.
  •  Silent operation.
  •  Continuous demand driven extract ventilation.
  •  No occupier interface required.
  •  Humidity sensitive strips with 30 year guarantee.

The results with DCV is a system that is comparable in efficiency to heat recovery, cost effective and simple, but most importantly, quietly monitors and manages air quality. DCV is not constrained by air tightness levels, so it is suitable for all house types and all ages, new builds and commercial unit to hotels and privately owned dwellings in Cork, Limerick and Kerry.

Heat Recovery Ventilation Cork, Limerick and Kerry

Should you install a heat recovery ventilation system onto your new home?

By installing heat recovery ventilation systems, you can block up those 6″ holes and let our fans quietly and constantly ventilate your home, while extracting any excess heat from the exhaust air from kitchens and bathrooms.

Where most people notice the benefits of the heat recovery ventilation system, is after a shower, as our unit will automatically boost the extract airflow to help clear the bathroom faster.

Its great for removing odours after cooking or after there has been high occupancy in the house or people have been smoking. In the mornings some bedrooms can smell stale and you need to open the window to ventilate the room.

With the Heat Recovery Ventilation (HRV) system installed, bedrooms are fresh in the morning and the house doesn’t smell after you host a dinner party because when you were sleeping, the system has been working to remove all the stale smells and replace the air with fresh, filtered and heated outdoor air.

Fresh filtered air is drawn into living spaces such as bedrooms and living rooms, providing continuous ventilation even when the house is sealed up for the day. By keeping humidity levels low and introducing warmed fresh filtered air to replace contaminated air, the quality of the internal environment is significantly improved. You can actually feel the freshness in the air within the house.

Continuous whole house ventilation can help reduce relative humidity to below 70% RH, which inhibits the ideal living and breeding conditions of the house dust mite.

Heat Pumps Installation

Heat Pump installation Kerry, Cork and Limerick

Heat pumps extract the warmth from solar energy which is stored in the ground, water courses and in the air. The systems use electricity to drive a pump which extracts the warmth and upgrades it into useful heat. Fridges are heat pumps and work by the same principal but in reverse, moving heat from inside the fridge to outside, providing cooling for the inside.

There are 3 main options; Air Source Heat Pumps, Ground Source Heat Pumps and Water Source Heat Pumps.

Driver Renewables supply and install heat pump to all business and public sectors.

Air Source Heat Pump
With air source heat pumps a fan draws air in to the unit and this flows over a closed loop of coiled piping circulating a fluid (either a mixture of water and anti-freeze or brine) which extracts the heat from the air. Air to water systems then use the heat to provide for central heating systems. Air to air systems mostly use fans to circulate heat into the property, but don’t produce hot water.

Ground Source Heat Pump
A ground source heat pump extracts heat from the ground by circulating a fluid through a closed loop of underground piping. This fluid absorbs the heat stored in the earth and carries it to the heat pump in the building.

Water Source Heat Pump
Water source heat pumps extract heat from a local water source and usually operate exactly like ground source heat pumps with a fluid pumped around a cyclical “closed” system. However, some systems are “open” and involve water being pumped out of the ground from a borehole and discharged via a heat exchanger to a river or sewer.

Combining Heat Pumps with Solar Energy
Heat pumps, being powered by electricity, are the perfect renewable energy partner for Solar Photovoltaic Panels (a method for generating electric power by using solar cells) as any free energy generated through solar power can be used to heat your home, so with careful use a heat pump and solar PV system in your home could mean an end to heating and electricity bills.

Heat Pump AWH V5+


All air source heat pumps operate under the same general principles.

However the differences in quality, technology and application vary drastically.

The new AWH V5+ series exhibits a number of cutting edge, technological and practical advances to create a comfortable living environment.

Nordic Style

The AWH V5+ series has been designed to fit in with the aesthetics of the modern home. The V5+ series comes with a grey powder coated metal housing, stainless steel cover and black coated grills and fans. These measures greatly improve the appearance of the unit but also serve to protect the longevity of the unit.

LEN Start Technology

The V5+ series contains our latest LEN technology. This technology allows the unit start the compressor and fan at their lowest setting. This technology prevents surges to the electrical system of the dwelling and reduces the noise of the unit.

DELA Design

The V5+ series represents the latest advancements in heat pump technology.  This series of heat pumps is of split design – DELA. In standard monoblock units the heating water for the dwelling flows through the outdoor unit where it is heated.

With the DELA design the heat generated by the outdoor unit is delivered to the indoor unit in the medium of refrigerant gas 410A. The heat energy in the gas is then transferred to the heating water in the indoor unit. This format greatly increases efficiency, especially in colder weather conditions and deicing cycles.

LÅG – Low Temperature

The efficiencies of heat pumps are maximised at lower temperatures. When they are utilised to generate high temperature the efficiencies drop dramatically especially in colder weather conditions.

This often results in the use of electric heaters and / or increased electrical bills. The V5+ series is a low temperature heat pump with its flow restricted to 48°C. With modern houses utilising underfloor and aluminium radiator heating the preferred flow temperature range is 30 -45°C.

For hot water generation we use the HEMERA hot water unit, which is specifically designed for hot water generation. This maximises the real life efficiency of the system.


Condensation often forms and freezes on the outdoor heat exchanger of a heat pump. This prevents air flow through the exchanger and so must be removed through a cycle known as defrosting.

Traditional defrosting cycles utilise the stored heat within a buffer or electric element to deice the unit steeling heat back from the dwelling and increased electrical consumption.

The V5+ series has a bespoke, proactive defrosting cycle, AVISA. An outdoor sensor on the heat exchanger indicates the beginning of freezing and before excessive ice builds up the AVISA cycle begins.

The AVISA cycle simply diverts hot gas around the heat exchanger, clearing the build up in moments and allowing the unit to revert back to providing heating.

Back Up Heather – Immersion

Immersions are often used to provide high temperature hot water, supplement the heating system and/or during defrosting cycles.

The V5+ series is one of the only heat pumps without an integrated electric heater.

At ES we believe that a truly efficient product, which has been developed to the highest of standards should not require boost or back up from additional heaters.

AWH V5+ Seamless Modulation

The V5+ series heat pump incorporates the latest inverter technology.

This technology allows a heat pump to match its output to suit the requirement of the dwelling.

The inverter technology continuously monitors the heating requirement of the dwelling. As the heat demand increases and decreases, the inverter increases the units output accordingly.

This technology drastically reduces energy consumption and creates an optimum living environment.

AWH V5+ also has Climate Adjustment Technology and works In conjunction with Seamless modulation the V5+ series

AWH V5+ Climate Adjustment technology

This technology works by increasing and decreasing the heat pumps flow temperature according to external temperatures.

The minimum and maximum desired flow temperatures are entered into the unit and the unit will control the flow temperature for the system based upon external, internal and desired temperatures.
