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.

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+

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.

AVISA Cycle

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.

Water and Air Heat Pumps

AWH V5+. Air/Water Heat Pump

Air to Water Heat Pumps

Renewable heating and hot water systems have become the norm rather than the exception.

With advances in technology an air source heat pump is possibly the most cost effective solution for any new build dwelling.

How They Work

Air source heat pumps generate heating water under

the same principles as your refrigerator cools its contents.

1. Energy is extracted from air and transferred to refrigerant gas.

2. This preheated gas is then compressed into a high temperature vapour.

3. The vapour is sent to the indoor unit.

4. Its heat is then transferred to the systems heating water.

Efficiency Heat Pumps

The efficiency of a heat pump is rated upon its coefficient of performance – COP. In basic terms this means the amount of electricity required to generate the output.

For instance a unit with a COP of 5, will require 1 kW of electricity with 4 kw from the atmosphere to generate 5 kW of output.
