Cosier Heat Ltd Opiniones 4

Big thank you to Ben and his team. Very professional team from the beginning until the end. We got many quotations with misleading information from many companies, including the big ones. Only cosier was able to make us take the decision to move from gas boiler and hot water tank to heat pump installation and hot water system with Sunamp. From the beginning, Dina was sharp with the right information with knowledge in the calculations and price. In the installation process Ben and Mark work hard to make everything OK. Ben is a great team leader. He always dealt patiently with all the situations in the process and keep us informed on the process to make it easier. Mark has an unbeatable knowledge and experience in these subjects, Furthermore, he is a perfectionist very good engineer. He worked hard with an installation that looks great and works very well. Now that all is done, we want to share our personal experience with Cosier but most importantly the great experience with the Cosier team. Thanks again.

Friendly, helpful & efficient

We had a fantastic experience with Cosier, they were such a delight to have around whilst doing the installation, were patient in explaining what was going on, considerate and tidy, and went above and beyond to ensure everything was working correctly. Fantastic service - thank you

A different company installed my heat pump but I'd had a nightmare trying to get them to come back to do a service. In contrast, it was easy to book a time with Cosier, and the engineer Mark turned up on time and thoroughly cleaned the outdoor heat pump. He showed me how the fins behind the fan had become dirty over time and that the heat pump would be working less efficiently as a result. Mark used some cleaning fluid to clean the heat pump itself and showed me the dirt that was starting to build up in the magnetic filter. After cleaning everything, he spent extra time going through the settings that my original installer had set. He noticed that the hot water had been set to run 24 hours (which was expensive), and set up a schedule so that it would only do the hot water heating in the night time when I get the cheapest rate on my EV tariff. He also set up "weather compensation" and explained how this would allow the heat pump to run low-and-slow instead of on-and-off at the fixed temperature set by the original installer. I got the feeling that my original installer had just left the controls on default factory settings instead of trying to optimise it to give me the lowest running cost.

I'll be using them every year from now on.
