Hi all
Sorry if this belongs in the Electrical section, but its equally a plumbing question too. Mods feel free to move if need be.
We have just had a 4Kw Solar PV system fitted to the house (Yes I know the FiT is now low!) so the gas boiler for water heating is now Off and the water heating is via the solar panels and a special power monitoring device and the 3Kw immersion heater element fitted inside the HW Megaflow tank.
Note: Megaflow (high pressure system) tank.
Up until now we have always used the gas boiler to heat HW but of course free daylight time electric is now the order of the day. But the noise the immersion heater is making is enough to wake the dead!!
It knocks, bangs and rattles. The knocking is transferred thought the upstairs flooring too! I can record it if it necessary.
But it does heat the water nicely!
So the questions are...
a) Is it safe to continue using it?
b) How can I easily stop the noise, if at all?
c) Being a pressure system, can I do it or does it have to be a specialist plumber in HP water systems?
Thanks for your time.
