generally very pleased (not about our downstairs control being removed for water cylinder in loft, now can only adjust by going up there, and we are OAPS)

The boiler that I had installed looks very smart and glossy white, however, as it is taking up less space than my old boiler which is better than before due to proper clearance space around it but the pipes that were boxed in before are now exposed and I now need to redecorate around the boiler but that is difficult as my kitchen design is discontinued and I did not recon getting a new boiler would lead to the expense of a new kitchen so I am not happy about having a bare brick wall. I have not been well since I got my new boiler, I am finding that the heat is like that from storage electric heaters which I would never have had in my home as they give my family headaches due to the dry air they produce, the new boiler seems to have done that to the radiators, so with trial and error I hope to find a setting which doesn't lead to a banging headache. I open my windows so it is not because I've no air circulating, I'm also finding that the radiators are only hot from the middle upward and not all the way up or all over, my old ones did that surely there should be an improvement having paid for my installation in full.

We were happy with the installer althought it took a half a day longer to install compaired to the salesman timescale. And the installer didnot updated us until the end of day one. Unfortunately your builder orginally left the drain in the centre of both back doors. Fortunately your installer made him to change it. We also expected a call a few days later to check if every thing was okay?
