Adding quartz heater

[Nozzle]

Evening all,

I recognise my post might attract flack from some regulars; as anything other than questions about changing a fuse usually do. Given this is a "DIY" site, and people come here to ask for good, sound advice, that is what I have come here to ask for.

I was given a quartz heater, brand new http://www.machinemart.co.uk/shop/product/details/honeywell-qh-803e-1800w-bathroom-heater. A range of outputs, the most being 1800W. I am going to mount this in my garage, a dry location that has recently been built and above the garage is the master bedroom. The box is lacking in advice about the minimum distance things should be stored away from it - one concern might be the plasterboard that is over the fireboarding the constitutes the ceiling - don't want to set that on fire!

Any how, I was consider either breaking into the ring main and diverting it to the heater and back to a plug socket, or perhaps just nick a spur from it straight from the socket.
View media item 67655What is the current wisdom when fitting this type of heater? Should I fit any additional isolator or protection?

Many thank for considering my post.

If you are going to power it from a socket circuit then you should use a fused connection unit to provide isolation and overcurrent protection. I would personally use a spur to feed the fused coonection unit, some seem to preffer to extend the ring but I don't see any real point myself unless you are planning further expansion later.

Before connecting a substantial fixed load to a socket circuit it would also be advisable to take a quick look at other loads (both fixed loads and likely portable loads) on that circuit and decide whether it is likely you would be overloading the circuit as a whole.

I started the job and then realised the low-profile box I bought to mount the fuse plate in has a snow-balls chance in hell of actually housing all the terminations. I'll pick up a standard sized one and refit. In the end I went for the option of breaking into the ring, only for the simple reason then there is never more than two wires in each termination.

Other loads potentially plugged into the ring include power tools upto 1000W, halogen lamp tripod (2*350), welder, 2.5HP Compressor, pillar drill battery charger etc, clearly not all going to be used at the same time though! The largest sustained loads are probably the welder and compressor - but I'd struggle to use them both simultaneously (though the compressor can cut-in by itself)...

What is the reasonable maximum load one should draw through 2.5mm2 cable ring main in conduit?

Actual - 23A.

It's a Ring final circuit. Ring mains are in the road.

Cheers!! (all about the terminology )
