We retro fitted this Grant r 290 into an old 1950s house just recently along with Ambiente underfloor heating systems Ambidec 20. I went back yesterday to check up on things with the customer and they were delighted. For someone that was a total sceptic he absolutely loves the system and the fact that it is giving a registered COP of 8.78 he’s even more delighted as it’s saving him money. We’re proving that done right, heatpumps DO work efficiently and CAN save you money.

We are very happy with the 12kw Panasonic heat pump installed by Energy Naturally Renewables that works alongside our solar panels. Their initial quote was comprehensive and accurate and addressed our system requirements. The installation was carried out by a small team of engineers who were quick, clean and professional. In addition, Darren is always reachable for any questions that might arise. I wouldn’t hesitate to recommend them.

I’ve decided to try one on my house. This is our third install of a Grant r290 in three months and I have to say we are impressed. We are now qualified for R290 installations and can offer our customers an extended Grant warranty.
