I had an old back boiler in my property which kept failing to work. I had many quotes from various heating companies, which I found to be very unhelpful and very expensive. I found that Coolheat were very genuine and honest. They explained that I could have two different types of heating systems in my property and they explained the advantages and disadvantages of both systems. We come to the conclusion that a combi-boiler with a vertical flue would be best suited to my house. The job was completed in 2 days and they used dust sheets and they took all the old boiler and rubbish away. I found that they made the experience stress free and i would recommend them to anyone.
