Boiler supply

[selfbuildy]

Do you normally have a separate supply for boiler?

Boiler is going to be floor mounted under a worktop.

What metal boxes shall i sink in wall and where???

Should i have a Switched Spur with Flex Outlet below surface of worktop.

boiler usually requires to be connected to a switched FCU with a flex outlet. Where you site it is up to you, but the switch must be accessible in case of emergencies, and for routine maintenance. The type of backbox you use depends on the type of wall . . .

seperate supply is preferred. less chance if loosing you heating if there is a fault. you will need 2 FCU for the boiler and if you have a room stat, youll need another flex from boiler to connection plate and then a 3C+E to stat

....and some cables to other bits and bobs depending on type of boiler. Are you having a HW cyliner, or is this a combi?

System is going to be oil combi with unvented cylinder for back up.That is if anything does go wrong with boiler got immersion back up. Heating system is underfloor heating downstairs, rads upstairs.

Underfloor heating is zoned, so i have run 3core and earth out to each thermostat from Underfloor wiring centre box.

Andy, when u say 2 FCU's, that is one above worktop for isolation of supply and then 1 below for connection of boiler?

Also, haeting system is going to have 3 zones, underfloor,hot water and heating upstairs(no thermostat)

Planning on running 1 3 core and earth from heating controller to boiler for hot water and upstairs heating and 1 3c and e to underfloor wiring centre box.

Also, can anyone recommend a reliable heating controller.Last Honywell 1 i had was rubbish!!

Thanks for replies so far.

Sorry if it sounds stupid

No - it doesn't sound stupid, nor is it stupid to ask if you don't know.

But it does sound as if you are lacking enough knowledge to be DIY-ing. If your name is a guide to what you're engaged in right now, what do your LABC think about you doing the wiring?

Probably know more about electrics than u could ever imagine shed head. I am a sparky, but with little experience of house wiring.

I'm unsure where to locate things thats all(read 1st message)That comes from experience which i'm trying to get from this site.

meeiow!!

A highly implausible postulate. And oh boy are you unaware of the intellect that you're trying to belittle.

I am a sparky, but with little experience of house wiring.

Not only is this a contradiction in terms, but it requires a new definition of the label "sparky" that was previously given to experienced and capable electricians, many of whom post on this forum regularly. In all likelihood, you are a fraud, selfbuildy.

Nuff said.

You have misunderstood what i meant softy.
What i meant little experience of positions of things, not wiring.

With all the posts u have written (need to get out more!) have any of them been advice or all been trying to be a cocky so and so. Are you a bloke? Cause you sound like a woman.

You have misunderstood what i meant softy.

No. I didn't. You wrote some words, I understood them. If you want me, or indeed anyone, to have a different understanding, then write some different words.

What i meant little experience of positions of things, not wiring.

However, those ones are incomprehensible.

With all the posts u have written (need to get out more!)

Thank you for your concern, but I get out exactly as much as I want to.

...have any of them been advice or all been trying to be a cocky so and so.

If you don't like me being what you interpret as cocky, then I recommend that you just ignore me.

Are you a bloke?

Indeed yes; and a particularly intelligent and good looking one if I do say so myself.

Cause you sound like a woman.

That just shows how easily one can get the wrong impression. For example, you sound like a pratt.

 

[selfbuildy]

I only asked where to put something.U started being cocky!

Definition of a pratt; 1671 posts in just over a year.

That's approx 5 a day. U definately need to get out more. Stop watching them porn channels. Stop wearing them tank tops and take the bunch of keys dangling off ur trousers off,u pratt! Get a bird!!!!

Clearly I am no match for your superior intellect and wit. However:

Self-explanatory methinks.

FYI, I'm earning money while I'm doing this. You're entitled to think I'm a pratt, if it so amuses you, but at least I can do simple arithmetic.

 

[selfbuildy]

Never mind mate.

You are losing it. Entitled to think ur a pratt? Can u remember what u even write. Paid for this! Ur better off as a traffic warden. U would have more friends.

Are u an electrician? Or have you just worked out ohms law was nothing to do with gays?

If we can put aside the trade in insults for a moment, you mentioned an FCU under the worktop. I think you need a fused DP switched spur above the worktop, to isolate the supply, but its output will want to go to a controller, which will want to be above the worktop (unless you are very short) and the output from the controller will want to go down to the boiler. So I reckon you need a single deep socket going to a double deep above the top, and a flex outlet (not an FCU) for power to the boiler plus a box for whatever multi-wire connection the boiler/pump/thermostats stuff needs. Personally I would run the power outlet sepatarately from the controls wires, because I find the knitting inside a boiler controler frightening, but it might be straightforward when you understand it.

On controllers, I'm coming to the view that the ones with a rotating clock are more straightforward than the digital ones with different daily/weekend/holiday settings; I've spent too long trying to train elderly relations and their carers how to operate one correctly.
