A recently installed Panasonic Aquarea K Series Air Source Heat Pump in rural Shropshire 2025. 

The new system replaces an old oil fired boiler therefore upgrading our Client's Home to a more healthier environment with a significantly lower carbon footprint.

Proudly, this project originated from recommendations from an existing Client whom also has a Panasonic Aquarea Heat Pump which we installed in 2024. 

Following a number of discussions with our regional Panasonic Representative and our Local supplier, Farr & Harris regarding the suggested Refrigerant Split options a second visit to site was arranged to obtain all of the essential measurements and other important information and a full room by room heat loss calculation was conducted with that data. It was determined that the Panasonic Aquarea K Series 12 kW T-CAP with a Panasonic Bi Bloc would be ideally suited for this project. The Bi Bloc houses all of the Hydraulic System Components within it. It also houses a 6 kW Backup Heater. Due to the airing cupboard being too small to house a Panasonic All in One Tank or standard size cylinder, the Slimline Joule 200L High Gain cylinder with 3m Coil would be the proposed solution for the Domestic Hot Water. As the Space Heating was 1 Zone of Radiators the Panasonic Controller could be mounted in the Hallway and used as a thermostat to control the Heating. A competitive Estimate was provided for our Client and with Client Consent the application for the Boiler Upgrade Scheme grant was also submitted which was approved a matter of days later. Our Client approved the Estimate and gave consent for the project to proceed. We would now confirm and schedule a start date. 

9 and 12 kW K Series Unit can be installed up to 30m away from the Bi Bloc

Smaller K Series Units can be installed up to 50m away from the Bi Bloc

There were more tasks involved in this project by comparison to other projects so it would need to be organised in such a way to keep disruption to a minimum and to leave the existing system in play until absolutely necessary to power down and drain down. 

It was determined that the garden groundwork would be done first so not to disturb our Clients daily routine and leave the existing heating on. We had the concrete base for the heat pump to be made and we also had to prepare the Concrete bases for the Composite Fence posts. Shovels at the ready, there's much digging to do!

The base for the heat pump was 600 x 1400mm and 7 inches thick. We used Concrete and rebar to form it. The fence post bases needed to be 600mm deep. The fence posts would be secured with four 150mm Thunderbolts per post.

To make provisions for the condensation waste water generated by the heat pump we would form a trench around the base which we would stone with decorative chippings. A trench that would accommodate the ducting for the refrigerant pipes would be prepared. As part of that initial fix a coil of pre-insulated dual 1/4" and 1/2" refrigerant pipe would be fed through the ducting and terminated a sealed in a location from which we could connect to it once the piping up began. 

We were able to coordinate the Electrical supplies to be installed by the Electrician without any disturbance to the existing system. The electrician had installed a separate mini consumer unit and rotary isolator switches for the new system which we could then wire from. 

It would be day four of the project before the system could be flushed and drained down. Each day of the project we had updated our Client on the stages we were at and what to expect for the next day and so forth so on the day of flushing and draining down the system our Client was well informed and had also been keeping busy baking the best Rock Cakes I've ever tasted. 

As it had been cold that week we wanted to get some heat back into the house and worked on Saturday to get the new system up and running. We would then return on the Monday to do the final tasks.
