Air Source Heat Pumps

What are Air Source Heat pumps and how do they work?

Pipelife Ireland specializes in Hitachi Yutaki Air-to-water Heat Pumps which 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

Frequently asked questions about Air Source Heat Pumps

Are Air Source Heat Pumps easy to install?

Yes, during a renovation or for a new installation. Hitachi heat pumps can be connected to all conventional low temperature radiators, underfloor heating systems, convectors and water heaters – tailored to your requirements.

How quiet is a heat pump?

Hitachi focuses on your comfort. Ventilator blades and scroll compressor have been specially developed for a low noise level.

What features make Hitachi Air-to-water heat pumps so energy efficient?

Hitachi was one of the first manufacturers to use DC inverter technology for heat pumps This keeps temperature fluctuations to a minimum, giving customers the opportunity to tailor the temperature of their homes to their own preference, whilst saving up to 40% of energy compared to systems without this technology.

Which Hitachi heat pump do I need?

It depends on many factors, including the size of your flat or house, the type and number of heating elements involved and hot water function. Your living environment also plays an important role. In general, you can use both Yutaki M and Yutaki S in connection with common radiators or underfloor heating systems. The Yutaki S heat pump is a split system, consisting of an outdoor unit and a separate indoor unit. In contrast, the Yutaki M heat pump is a compact solution, whereby only a single unit has to be installed on the outside. It does not take up much space and can use an existing heating solution. Your Hitachi specialist dealer will be happy to help youmake the right decision.

Do you want to heat and regulate temperature?

No problem with the Yutaki S! The Yutaki S is a split system comprising an outdoor unit and a separate indoor unit. They are connected via a refrigerant pipe and are installed by a trained professional. All sizes are equipped with an electric heater as standard, which can be switched on as needed. This is particularly beneficial in transitional periods. The use of convectors as a heating system means that the Yutaki S can be used to regulate indoor temperatures in summer. It is especially suited to new builds that you ideally want to equip with underfloor heating. Its screed drying function is a real advantage here, which shortens the drying process considerably. It also has a legionella purge cycle, automatic summer cut-off (this does not affect service water heating) and the option of solar connection.Thus, its use can be customised all year-round.


Yutaki-M 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.


Yutaki-S Combi Split Tank 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.
