Hi,
I'm looking into the GHG - been put off ground source heat pump as it means digging up entire garden; bit put off air source heat pump by need to replace all radiators and replace a new-ish boiler. Now considering Solar Thermal as an 'easy' way of doing something to improve my homes environmental impact & reduce bills. Has anyone else accessed the GHG? What have you had done? Are you happy with it? Anyone got solar thermal system? Grateful for any views - it's making my head hurt...
