Fitting electric heater NOT storage.

[superthornt]

Hello,

So as a newly qualified domestic installer, I have been given a job that means getting rid of a domestic central heating system and replacing with electric heaters. Noe first thing Im going to do is upgrade the fuse board, here is the rad sizes by kw

Downstairs
1 x 2.5 kw
1 x 1.75 kw
1 x 1.0 kw
Upstairs
2 x 1.0 kw
3 x 0.5 kw

Basically, Im asking for anyones advice how they would go about running this in. Do i need to run 1 x 4mm radial to upstairs rads and 1 x 4mm for downstairs???

Sounds like a plan.

Now you need to plan the rest of the circuit.

well depending on distance and vd and earthing sytem and installation methods your slightly out i. maybe

Seems like an expensive to run method of heating a property.

Personally, I would be splitting them up over more than just 2 circuits to allow some to remain in use should the OCPD or RCD operate for any reason.

Radial to each heater imo opinion. That way, when they realise how expensive it is to heat it that way, it will be all in place to convert to eco 7.
Does your new install comply with "an efficient way of providing heating"?

Problem is they got an oil boiler heating system but dont want it anymore. they wana have eco electric heaters which is beyond me. My guess is they cant afford the oil.

If they've been fooled into those "eco" electric heaters tell them to steer well clear. Was an article in the paper the other day about a council who had installed a load of them a couple of years ago and are how having to rip them out and install central heating.

8.75kw of electric heaters, they had better get an LCD meter installed or a new bearing in the old meter. Why would they not use storage heaters?

May be an idea as others have said to keep the old system in place for when they get the leccy bill as the oil would have been cheaper.
