#heater

Hi all I have a dimplex electric wall mounted heater that is currently not working and flashing red with error code 30. I have turned off and on at the wall and problem persists. I read elsewhere that the common issue is that the overheat stat has failed but I’m not sure if/how I can resolve...

Hello, Sorry if this has already been asked and answered, but I have an unvented water heater and I was wondering if it will be a problem if I turn it off while on holiday ? Could it give pressure problems or anything? Thanks, it's first time I have one and I am kind of stressed about it.
