Looking at Quantum storage heaters, 2 QM125s (lounge, hall) and 1 QM100 (kitchen) totals 7.72kW input. It’s possible that a QM150 would be needed for the hall as it has a stairwell which then takes input power to over 8kW.
Would this still be ok?

No. I'd connect the lounge ones to the supply for your existing heating.


However, it annoys me to hear that you have given up on this Danrv. Are you perchance in Berkshire, and would you like me to take a look at it?

You should be looking at heaters that will supply sufficient heat to heat the space. So do your heat loss calculations to find out what size heater (or heat loss) you need to compensate for.

Getting a super duper undersized Quantum that doesn't actually heat the room and then having to run the auxiliary heater on full price leccy probably isn't the best or most economical way to heat your place.

Thanks. Based in South Cambridgeshire.
I should’ve mentioned I have contacted a local appliance repairer and also a company that replaced the fan a few years ago but no replies yet.
Will persevere.

Firms only want to replace stuff nowadays. You need a young lad interested in electricity if you don't want to do it yourself.

Yes. A couple of companies haven’t replied. Makes you wonder why they advertise a repair service.
I did get a helpful reply from an Electricaire Spares company in Scotland. They listed the components that may be causing the problem and offered to fix it depending on location.
I would like to fix it myself and do repair most things. I have another local electrician to try first.
