Dimplex Quantum QM150 Storage Heater Off-Peak Supply Wiring Help

You need to get a 2nd opinion. This, all sounds wrong and I'll thought out

And fast

In my opinion what they have done is unacceptable, and the fact they have offered to install the correct supply at their own cost suggests that they are aware that what they have done is unacceptable.
I would insist that they make good to all of the holes etc they have made, and route the cable in a manner which you find acceptable.

Hello all - hope everybody is having a grand weekend so far!


So I've just had the installers leave (2 of them this time, one who was obviously much more competent and experienced that the chap who attempted to install the heater twice with not much luck).


What they have now suggested, is that the heater in the bedroom is changed from the QM150 (3.3kW) to a QM125 (2.7kW) - obviously at their cost.


The more experienced installer did point out to his colleague that the 20A DP switch should not have been connected to the ring main, as the ring main was protected by a 32A MCB (and therefore the heater was not protected to 16A as it should be).


He said that considering that the current draw for the QM125 would be less than 13A, it would be appropriate, safe and abiding to regulations (he said that electrical testing would pass, should I require this in the future for renting out etc.), for the off-peak element to be connected to a 13A fused spur (connect to the ring main), via a 16A rated timer.


How does this sound to you guys? If you feel that there still needs to be a dedicated circuit, I'll give these guys a call back on Monday and tell them I am not interested in their suggestion.


Many thanks again for all of you that have helped out with this over the past few weeks. It's so impressive and touching that so many people are willing to take a little bit of time out of their day to help me out with this.

Although I am starting to understand the basics, it really does help having you all support my efforts to ensure that the installation is carried out in the correct manner, ultimately leading to me and my family's safety!


Kindest regards,
P

My only comment is that the "timer" could be changed and therefore the tenant could use day rate electricity to heat the storage heater.

Is does sound like the installers have improved the situation

Many thanks for the speedy reply Murdoch!

Glad to hear that you feel that the situation has been improved - does give me much more comfort.

Agreed that the timer can be changed, however for now I am living at the flat and therefore am aware of how the timer will need to work. Down the line, yes, tenants would need to also understand this (n.b. the main reason I mentioned renting out is due to the fact that I understand electrical testing would need to occur - which I don't want a risk of failing with the setup that they have suggested).

Thanks again,
P

What certificate(s) have the installers provided?

No certificates have been provided...I didn't realise I needed one to be honest....

What should they have provided. Do I need to request one?

Cheers

I wouldn't accept it personally, the regs suggest that significant space heating loads (those over 2kW) should not be connected to a ring circuit
