We as a company have now fitted hundreds of Hounsfield boilers and can't thank Andrew enough for his service. I thought I'd give him alittle shout out today as he's helped one of my dear clients out. I spoke with Andrew this week to explain one of my clients had a problem with his boiler that has been in 5 years. No fault of Hounsfield but my own client had lost his wife to lung cancer and had forgotten to get his boiler serviced for 2 years. As a result some of the door seals had gone wrong and the boiler was in alittle bit of a state. I explained the situation to Andrew and sorted the boiler

We have fitted a number of Hounsfield boilers recently and have been very pleased with the product. They are simple to install, easy to service and are very quiet when in operation. We are very fortunate to have a great manufacture on our doorstep.

Had been looking to replace my old boiler but didn't know who to use or which boiler. I was recommended to Hilton heating who suggested a Hounsfield. I decided to do some research and unlike all the other makes had all positive feedback. I sent an email to Hounsfield and within a short while the owner contacted me and gave me lots of information. Also sent me literature. My new boiler has now been fitted, looks smart, small and quiet, was replaced in a day, working well. Early days yet as I am a pessimist but all good so far, seems to be more efficient too.
