Air to Water Heat Pump

It is clear that our planet is changing and changes need to be made to the way in which we heat our homes. A method of heating our homes resulting in less energy consumption, lower running costs, and dramatically reduced CO2 emissions and carbon footprint is required. There is a clearly a need for something different. Something Renewable.

With the support of Government schemes and homeowners wanting a better solution to these concerns, new and innovative ways of heating homes have been developed.  These systems involve new and more efficient ways of heating and delivering hot water to your home compared to traditional ways of heating your home such as oil or gas boilers.


Air to Water Heat Pumps can provide that solution.


Pipelife Ireland specializes in Hitachi Yutaki-S Combi Air-to-water Heat Pump and Midea Mono Bloc Units. Heat Pumps operate by transforming energy from the outside air into heat, meaning every 1kW of electricity used to power the heat pump is capable of providing up to 5kW of energy in a well-insulated home – helping to reduce heating bills by up to 60% and cutting CO2 emissions by 50% compared to traditional boiler-led heating systems.

Air source heat pumps extract heat from the outside ambient air all year round, even at temperatures as low as - 25°C. Compact and virtually silent outdoor unit with award-winning DC Inverter PAM technology. We offer two variations on the Air Source Heat Pumps, a Mono-Bloc unit and a Split Combi Unit



  • Lower fuel bills

  • Outputs from 5kW to 16kW
  • From 600mm compact height options
  • Integrate with other renewable technologies
  • 5 year warranty.

How does an Air to Water Heat Pump Work?


Air to water (or Air Source) heat pumps utilise energy in the outside air and transforms it into usable heat. This is performed through a refrigeration process and a vapour compression cycle, which sounds very complicated, but it’s basically how a fridge works, but in reverse.

Heat pumps work much more efficiently at a lower temperature than a standard boiler system would.  An air to water heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside. It can get heat from the air even when the temperature is as low as -15° C.

This makes them very suitable for underfloor heating systems or larger radiators, which give out heat at lower temperatures over longer periods of time.

An underfloor heating system circulates low temperature water. Most conventional heating systems circulate higher temperature water, usually between 50ºC to 80ºC whereas an underfloor heating system circulates water between 25ºC to 40ºC.

An Air to Water heat pump is the most modern and efficient way of generating this low temperature supply of water.  A heat pump is the most efficient way of heating your home and your domestic hot water requirements for Irish climate conditions.  Air to Water heat pumps also dramatically reduce CO2 emissions and carbon footprints.

Air to Water Heat Pump Split System

What is the difference between a Split & Mono-Bloc Heat Pump?

A ‘Split’ unit does exactly that. It splits the refrigeration process between the outdoor fan unit and the indoor unit. So the compressor is in the outdoor unit and two pipes containing refrigerant connects to the indoor unit where the heat exchanger and water side is contained as well as the main controller.

The benefits of the Split unit is that the outdoor unit can be located further away from the property (typically up to 50m) with little off no heat loss. Also the outdoor units tend to be smaller and quieter.

A ‘Monobloc’ has the compressor, heat exchanger and water side of the refrigeration cycle all contained in the outdoor unit. Therefore, this requires no special qualifications to install as this is much like a boiler installation.  

Our Product selection

Mono Bloc Heat Pump

Mono Bloc Unit

A compact solution where a single unit is installed on the outside of the property, taking up no space inside and can be used alongside an existing heating solution. The heat pump is connected to the indoor heating system simply by laying two heat insulated pipes and the electric connection cables under the ground.

Air to Water Heat Pump

Split Tank Combi Unit

The Yutaki S is a split system which produces hot or cold water to supply radiators, fan coil units, underfloor heating or a combination of these. When connected to a tank, it can also be used to produce domestic hot water.
