We moved into our renovated build in November 2013. We had solar panels and heat recovery ventilation system installed by Greentherm. We have been so pleased with the running of both systems. The house is never stuffy and still smells of a new house. In the summer fresh air on full blast keeps the house cool and in winter the heat recovery extracts the heat from 2 stoves in living areas to all other rooms.
Excellent I have to say. Solar panels likewise are very efficient with constant hot water on tap. A little while ago I realised the panels were not doing their usual job so I called up for a service. As it turned out my panels were working perfectly after an inspection from Kevin but he found a problem (a leak) nothing to do with the installation by Greentherm I add. I called the plumber and was able to tell him what was wrong and was fixed immediately. Excellent service by Kevin from Greentherm.. I would highly recommend Greentherm and their products.
