All good until the install DAY the plumber was grumpy, short and sharp in his manner, messy and damaged our Victorian woodwork on the way in and then denied it once we had complained, Heatable claim they make the process better and vet and train their tradespeople, not this time it took use 2 hours to clean up after him and then redecorate where he had damaged our hall wood work!!!! Would I use Heatable again? NO The after sales dept have your evidence and photos to complain against the plumbers denial of any wrong doing, same old issues they state to have solved in there sales speel and marketing, the two guys that set it up need to vet the plumbers doing the job as it was a more stressful experience for us, wish we had used a local company !!!! He even left the Exhaust pipe for us to dispose of!!
