My disabled daughter’s hot water has stopped working. It’s a relatively modern Potterton boiler with an indirect sealed hot water system and a Nest controller. I’m familiar with the old gravity and pumped hot water systems and the new direct systems but not with sealed systems.
Recently she had to have the motorised gate valve on the heating side changed and one possibility is the one on the hot water has now failed. I got them to manually open the hot water motorised valve but that didn’t work. But other than that what else should I look for? Do these systems have a separate pump or is it built into the boiler? There is a pump for the heating side but nothing obvious for the hot water.
The boiler itself is working and running the heating, just not the hot water. Manually overriding the Nest at the HeatLink also didn’t work Trying to do remote diagnosis for her as money is tight and the replacement of the heating gate valve was not cheap for her. Last time - plumber charged her £85 for just the motorised head part . Any thoughts or ideas appreciated.
