How long should I be heating my unvented cylinder

[dwaindigital]

Hi All,

I have a tempest 360litre cylinder with a Ecotec 637 (37kw) all tucked away in the loft.

I currently heat it for an 1.30 at 7 a.m. in the morning and then for 3 hours at 6pm till 9pm
I actually wasn't sure this is the best way to heat it as I've read you should leave it for 6 hours over night.

What say you on best practices?
For me the water is always piping hot as we set the temp to 60 degrees

Cheers in advance

Problem is yours is a horizontal cylinder so it actually doesn’t store much hot water unless you have a de strat pump fitted

Tbh I would leave it on constant it will regulate it self via it’s thermostat

Doesn't really matter, if what your set to now is adequate ? then leave it there no big benefit of heating it overnight unless your using electricity to heat the tank . Kop

Hey, Thanks for your reply.
I think I do have a destrat. I don't fully understand it but think it keeps hot water flow in the cylinder.
If I leave it on all the time I think it will fire up more often than I'd like even with it regulating itself

That's what I was thinking overall. I suppose if the demand isn't outpacing the supply of hot water then it's fine.
I think I was worried from a maintenance side of things and if there is a minimum requirement for a tank this size. I think I read once about inverted pressure blah blah

2 hours should be ample then so try 2-4am
