Like others have stated I too was apprehensive about buying a boiler online. I read other reviews and even contacted Heatable with a couple of queries these were answered promptly and professionally. I went ahead and competed the online ordering process which was a very easy process my order was placed on Friday evening and my new boiler was expertly fitted by Dale & Tom the following Monday. A special tanks need to go to Dale & Tom who worked professionally, efficiently and were very friendly. It is coming up 6 weeks since installation and the boiler is excellent I honestly cannot fault Heatable in any way 10/10. What I will say is you get a quality boiler expertly installed at an extremely competitive price from a company that provide excellent customer service.
