Had new boiler installed last Dec 2019 - couldn't fault the service then. Last week boiler filter sprung a leak and, so far, Heatables ability to address even a simple replacement in-line limescale filter has been inept in the extreme. I have wasted 3 days waiting in so far for them now to tell me they need to order a filter (a fact that I informed them of last week). Do yourselves a favour, consider the aftercare as well as the price you pay as I have found, Heatable DO NOT deliver what they promise. Update - after some initial confusion, Sam at Heatable bent over backwards to get the fault sorted the next day. Okay, these things happen but I have to stand corrected and say well done Heatable and particularly Sam for restoring my faith and earning the full 5 stars I have now given. Thanks again.
