- Our system has been in for two weeks now, with temperatures below freezing and windchill temperatures at around -12c. The system has functioned perfectly, and it is lovely to have hot water and hot radiators rather than the lukewarm we had previously. Lewis and Ben were completely professional with the installation, and we're happy to answer any questions we had, and the making good on the Saturday was better than we could have ever imagined. Thank you for looking after us, and the reassurance throughout. Looking forward to future dealings with you, have already recommended you. Thank you.
