If I could give a rating of my own it would be -5. We had a Air to water heat pump installed almost 3 years ago. The biggest mistake we have ever made. We have sent letters to the managing director Joe Searle over the last few years with problems we had at the time and since. So far we have not received any replies or the courtesy of even phone call. I am at the moment I am trying to get them to sort out another problem that has recently occurred. I phoned them 2 weeks ago and spoke to Lucas who took my details and said he would get someone to contact me. Yes you have guessed it I am still waiting. I have phoned twice today and all I get is the answer phone.
