Heatable website gives a straightforward comparison of a variety of boilers, this was really useful when making the decision of which to buy. The on line ordering process was extremely easy and I was contacted by telephone to confirm and settle any questions I might have had. I sent photos of my existing set up on line and was again contacted by phone the day before delivery. The fitter and electrician arrived on time, worked quickly, efficiently and cleanly. My new boiler was installed without problem and is working brilliantly. I would recommend Heatable without hesitation.
