After a lot of research on combi boilers, installation companies and prices we chose Heatable because they supply Veissmann highly rated combi boilers, the reviews of their installations was five star and finally their prices were very competitive. The result was we placed our order on the Sunday and had the boiler installed the following Wednesday. The communication was excellent and the installation straightforward, nothing was too much trouble, the installation guy was brilliant. The follow up satisfaction checks, guarantees and certificates all very professional yet friendly. We would not hesitate in recommending.
