My boiler install was carried out on the 14th December 2021 ( Viessmann Vitodens) First the positives, the web site was very easy to use and the options available were very good, booking in the boiler install was very easy and all within a very acceptable time scale (considering the time of year) Unfortunately they are the only positives The boiler was poorly installed with the following issues- Gas Leak at the gas meter test nipple ( Unacceptable) The engineer left the property without checking the test nipple after he had used it ! Flu incorrectly installed ( No fall on the vertical section to the boiler) Condense pipe poorly installed No Non return value on cold water inlet to the boiler No Gas bond on the gas pipe Poor messy workmanship on the flu installation ( See pictures) Insecure plume kit Concrete walked up and down driveway Chemical flush not carried out As per Heatables T & C’s Two Gas safe building compliance certificates issued, one with an engineers name that had nothing to do with the installation?? Heatable never return Email’s for some reason and only interact over the phone after YOU have called them. Heatable have since sent another engineer out to rectify the above issues and given us £100 to have the drive jet washed. But Heatable offered NO apology for the dangerous installation, which is unacceptable. You can best judge how good a company is ,when things don’t go as planned, and Heatable were just about the worst I’ve come across, so in conclusion if your looking for a boiler to be installed, look for local recommendations and don’t take the risk of Heatable.
