Aims and objectives

  • To raise awareness of the features and benefits of heat pump technology by freely sharing accurate information and guidance to the general public and in particular end users, specifiers, energy advisers, and installers.

  • To co-ordinate technical and market research with the aim of improving market opportunities and overcoming barriers to the adoption of Heat pump technology in the Irish market place.

  • To freely transfer and share information on international best practice within the Irish Heat Pump Industry by supporting members and the public with first class information and education.

  • To influence national legislation, regulatory and energy efficiency standards, to ensure heat pump technology has a central role in the Irish market in delivering the national energy efficiency and carbon reduction targets.

  • To provide advice, technical and costing information to national government, local authorities and public bodies, in legislative, regulatory and energy efficiency matters, to facilitate informed decisions in the preparation of energy, environmental and trade policies affecting the Irish Heat Pump Industry.

  • ​To actively promote best practice design, professional installation and the appropriate application of heat pump technology in the Irish market place for residential, commercial and industrial applications in line with legislative and regulatory requirements, industry best practice, and environmental conditions, both at a national and local level.

  • To maintain the integrity of the Heat Pump Association by ensuring all its members promote a high standard of professionalism and service in the Irish Heat Pump Industry.

  • To transfer and share international best practice with other markets.


What is a Heat Pump?

In simple terms its a money saving device for your building. Like a refrigerator or air conditioner, a heat pump forces the transfer of heat energy from the ground, water or air to the application. Using motive power to run the heat pump's process effects the transfer of several times as much energy to the application, be it heating, hot water or even cooling.

In theory, heat can be extracted from any source, no matter how cold, but a warmer source allows higher efficiency.

The relationship between how much power we use, versus how much energy is delivered, is known as a COP (or Coefficient of Operating Performance). If a heat pump uses 2 kW of power and delivers 8kW of energy it's COP is 4 (8 / 2 = 4), a typical figure easily achieved in Ireland for an air to water heat pump for instance.

A ground-source heat pump uses the shallow ground or ground water (typically starting at 10–12 °C) as a source of heat, thus taking advantage of its seasonally moderate temperatures. In contrast, an air to water heat pump draws heat from the outdoor air and in colder weather thus requires more energy or often a secondary source of heat for extreme weather.

Closed loop geothermal heat pumps circulate a carrier fluid (usually a water/antifreeze mix) through pipes buried in the ground or in boreholes. As the fluid circulates underground it absorbs heat from the ground and, on its return, the now warmer fluid passes through the heat pump which uses electricity to extract the heat from the fluid. The re-chilled fluid is sent back into the ground thus continuing the cycle. The heat extracted and that generated by the heat pump appliance as a byproduct is used to heat the house

HEAT PUMP Technology and Application overview

Air source heat pumps use the ambient energy in outside or exhaust air for heating, and preparation of hot water.


(Also commonly referred top as Air-to-Water Heat pumps.) 


These compact machines gather heat from the outdoor air and distribute the heat through water based systems such as underfloor heating and radiators. Recent advances in this technology have made air to water heat pumps a very popular choice in the mild climate of Ireland.


They have low acquisition costs as there is no geothermal drilling or surface collectors required under the soil.  They are a very popular choice for new-builds to allow compliance with Irish building regulations as a stand-alone solution.


With the aid of a ground source heat pump, solar energy stored in the ground can be collected and used to heat your home. Often referred to as geothermal heating, the heat collected is mostly from the sun in fact and not the earth’s mantle! The heat pump extracts heat from the ground either by  a vertical or horizontal collector. Heat is commonly distributed by underfloor heating or radiators. Ground source heat pumps can also be used for passive and active cooling of buildings, whereby the excess summer heat is removed by the floor heating or fan coil units and stored in the rock for use later!

For air-tight, low energy builds, where ventilation is a must, an Exhaust Air Heat-Pump may be an ideal choice. This will re-cycle the heat from your house’s ventilation system. These machines are ideal for apartments (there are no outdoor parts) 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 utilised through heat recovery. Some exhaust air heat pumps can also draw additional air in from outdoors to harness additional energy too.

The heat is retrieved from the outside  air through an outdoor module, where the refrigerant, which circulates in a closed system, transfers the heat from the heat source (outdoor air) to the indoor module. 
These heat pumps provide ideal stand-alone solutions especially suited to small garden rooms, home offices and apartments and do not use a water-based heating system such as radiators, just the indoor module(s), usually located at high level on a wall or even ceiling mounted. 
Larger versions with multiple indoor units are often seen in hotels etc.
Most can also be reversed for cooling in summer too.


Cost Comparison with other fuels


If ground water is available and easily accessible, it can be utilized as a heat source due to the fact that it has a temperature of between 7 and 12 °C all-year round. It is advisable not to pump water for single and two-family houses from a depth greater than approximately 15 m. This would lead to expenditures being too high.

A distance of approximately 10 to 15 m should be kept between the withdrawal point (supply well) and the reinsertion point (deep-well) and furthermore the flow direction should be taken into consideration in order to avoid a “flow short-circuit”.

​Running Costs for an Irish Detached Home based on energy requirements of 25,000 kW Hrs per Year for all heating & hot water

  • Figures are taken from SEAI's domestic fuel cost comparison sheets January 2020. Usually published bi-monthly, these are market average figures.

  • Clearly, it shows the lower operating cost of a heat pump or any of the other commonly used energy sources, especially fossil fuels.

  • *For the heat pumps we have taken an average seasonal C.O.P. of 4 (a modest value; many have higher COP figures)

  • *Electricity Cost is based on 50% Night Rate, 50 % Day Rate (band DD)

  •  For example, a house using  25,000 kW Hrs of energy - on gas oil would cost €2682.00 versus €945.00 for the Heat pump, a substantial annual saving of €1737.00
