Combi Boiler Supply

[rmaynard]

I have put in a new supply for a combi boiler, its supplied off of a 16a mcb on the RCD side of the board, can i add a single socket for the water softner/calc inhibitor that fits round the pipe?

No reason why not

 

[sedgy34]

corse you can its a radial

i thought it would be ok but just checking

Just make sure you fuse the combi-boiler SFCU at 3A and do the same for the softener.

Oh, and use heatproof flex on any cabling which runs inside the boiler itself...

Thanks, im only doing the supply, the boiler wiring will be down the heating engineer

Heating engineer will usually want you to get a 3A supply to the boiler itself. You must have have a heating engineer who knows what a cable is

For heating engineer read plumber, enough said!

Just a quick question; is there an option of running boiler off an rcbo as this should be the preferred method, a fault on any other circuit married up to same rcd could see a loss of hot water and heating as well, if the property has other means of heating (gas fires) then not such a big problem.... loss of heating when its minus 10 outside because of an unrelated fault is a thought to be considered in design, thus should be avoided.

This was also my preferred choice but was unable to physically fit an rcbo into the CU

If I'm running a feed for a combi boiler I tend to use a 6a RCBO. This is fairly rare though cos in many cases it's easier to spur off the kitchen sockets circuit. Having the boiler on its own RCBO though is definately the way to go if possible - however the benefits of having a dedicated circuit are somewhat negated by not using an RCBO.

have you tried using one of these?

In the last 10 years at my current address I have lost heating and hot water twice. BOTH times were when the boiler packed up and nothing to do with earth faults.
If you are going to take that train of thought to it's conclusion then a cooker should be on it's own RCBO (hot food is important) and so should every other "system" in the house.
I think we are getting obsessed with "what-ifs" in this Country. Soon we will be a colony of the US of A.
