Following on from a similar post about vacs, the heaters in my machine take an age to get properly hot, i.e. 'burn your hand on the connect hot'.
In a 2 bed I'll be at the bottom of the stairs before I get to this stage, even if filling from the customer's hot tap. I'm guessing they're on the way out - maybe scaled up inside? We live in a very hard water area.
I recenly bought a back up machine which has has an immersion heater fitted and it beats the poo out of the inline ones. I'm thinking that if I have to have the inline heaters replaced I might see if I can have an immersion one fitted instead.
Any views welcome
