Chasing walls for E7 wiring

danrv

Hi
I’m soon going to install three Quantum storage heaters downstairs in my semi detached property.
The original Economy 10 electric warm air heater uses a switched off peak supply and a 24 hr supply so there’s no wiring in place 
for the Quantums.
The walls I think are concrete block so was wondering about chasing in cables. May not be much to do, depending on 
whether or not a supplementary E7 board can be installed.
Any help appreciated.

 What sort of help do you need?

What floor is it? Can you run the cables under the floor or in the ceiling?

I hope you like dust

If you can go from underneath it would be a lot easier.

attach a henry hoover to one of those and it does away with 95% of the dust

Just advice on chasing into concrete walls. Floor is concrete too.

Good idea, thanks.

It's either the above machine or a SDS chisel (or both - cutting two sides, than chiselling). The latter can be used for many other jobs. Blocks are very easy to chisel.

And again, ignoring the dust issue, cutting can be done by a more universal angle grinder.

Personally, I'd cover the cables with steel channel/profile, but this isn't necessary. And don't forget, the channels you make in the wall have to be strictly horizontal and vertical starting from the sockets or fused spurs.

Consider running cables in the ceiling and vertical channels down.

Thanks. I have an angle grinder and chisels. I’ll ask the electrician about routing as there’s already sockets near where I’m putting the heaters.
