    Managed to boil my hot water tank with immersion heater...

    Woke up at 6AM to the sound of my hot water tank boiling and a cold sweat as I realised I'd left the immersion on since 6PM the night before. Immediately turned it off and opened the taps in the bath to drain the tank, temporarily turning my bathroom into a steam shower - still not sure if this...

    Instant hot water heater before or after pump?

    Hi, I have a bespoke system in an old building I did myself. At the moment I have the pump before the instant hot water heater. I wondered if it would be better to put it after the pump? So it pumps cold into the heater, rather than pulls hot out of the heater. Thanks for any help.
