Ecovision did exactly what they said they would !! From survey to installation they were on top of the whole event which was a big decision for us, yes, we had a few teething problems that were expected but Ecovision shone through to sort and even just recently we had another small fault and they were on it and all sorted. Thank you Ecovision, we would recommend this company to anyone who is thinking of this major change in renewable heating, since we have changed to the new system it is by far more efficient than our older LPG boilers, the house stays exactly on the 21 degrees it's set at but the radiators are not boiling hot, it takes a while for you to get your head around how smart the newer technology is. With the RHI payments for seven years it's a bonus on top of that. Best wishes. Richard Bone West Sussex.
