Considerations for Air Source Heat Pumps


The average household in the UK emits 2.7 tonnes of CO2 every year from heating alone. Switching to air to water heat pumps to provide heating to our homes such as the Panasonic Aquarea J Generation with R32 refrigerants, housing emissions can be lowered significantly, plus residents can save up to 50% on their fuel bills.

Air to water heat pumps is the future for the housing sector and an essential step in challenging the climate change problem.

Air source heat pumps currently on the market are very reliable, are quiet in operation and highly energy efficient when compared to oil-fired boilers or electric heaters and can be play a large part in lowering carbon emissions. Further efficiencies can be achieved when linked to smart controllers to produce significant savings for heating and domestic hot water (DHW) provision.

Panasonic’s Aquarea range of air to water heat pump solutions use only a small amount of electricity to turn surrounding air into hot water to heat our homes and DMH. The new Aquarea J Generation has improved comfort in extreme conditions with temperatures as low as -20˚C.

Heat pumps can be connected to existing radiators, underfloor and fan assisted radiators to deliver heating in the winter, plus dedicated cooling can be provided during the summer if required from the units.

Panasonic Aquarea A2W Heat Pumps are proving popular with housing associations and developers looking to provide highly efficient heating and hot water, whilst also providing homeowners with a reliable system offering long-term energy savings. Andy Denton, Director of Marshgate Properties commented, “Selecting sustainable energy options is high on our list of important aspects for the homes we build. We had already installed Panasonic Aquarea Heat Pumps on a previous project a year earlier and have been impressed with the units and their performance. This approach has proven successful for the heating and hot water provision for our latest projects.”

Panasonic is currently working with several social housing providers, including West Highland Housing Association in Albourne where approx. 80 Panasonic air source heat pumps have already been installed this year with a further 60 being installed over the next six months to existing housing stock.

The Panasonic Aquarea range utilises air-to-water heat pump technology by converting heat energy in the air outside into household warmth, the highly efficient Aquarea technology helps to reduce CO2 emissions and the environmental impact. Furthermore, the range can synchronise with solar panels for an even greener solution to optimise the use of energy in the most efficient way.

Design considerations to ensure the correct size heat pump for each project

Panasonic has a wide range of air source heat pumps to suit different property types from one-bedroom apartments to six bedroom detached properties and all those in between. To help simplify the choice of selecting the right heat pump size and type for each project, Panasonic has recently introduced its Aquarea Designer, the online tool to help heating and cooling designers, architects, design offices, installers, and distributors alike. The newly developed air-to-water design tool is optimised to help professionals easily identify the most appropriate Aquarea air-to-water heat pump for a particular application, to calculate the savings compared to other heat sources and to calculate CO2 emissions very quickly.

This bespoke program from Panasonic helps to promptly design and size an Aquarea heat pump system, allowing users to identify the correct application for them at the simple click of a button. Users can compare investment and operational costs compared to other heat sources. It also calculates the savings and swiftly calculates CO2 emissions. The system can produce a Heat Pump Design Report which includes product web links for heat pumps and DHW tanks and can be individually selected to include the following information: operational costs, investment costs, detailed product information, and ErP label.

The Panasonic Aquarea Designer will calculate the project’s energy costs in terms of domestic hot water, heating and cooling demand. It will furthermore show the total heat consumption by operation mode and the calculated SCOP (Seasonal Coefficient of Performance). It then allows the designer to show clients a comparison with other equipment options such as heating by conventional gas-fired boilers, oil fuel systems, pellets and standard electric heating.
