not quoting for boiler/ufh controls

J.C.E · Sep 23, 2017

Evening evening!
I find I am losing potential builders/devoloper clients by excluding controls from my quotes (basically I have never learnt- so always shyed away from doing it)
is it really that differcult to do from scratch?!

I know and have done nest wiring for combi- thats fine

and if I just base 1st fixing on the following- will I be good to go...

y plan 1 zone UFH- https://www.ukunderfloorheating.co....016/07/Wiring-before-mid-position-valve-1.pdf

s plan 1 zone UFH- https://www.ukunderfloorheating.co.uk/wp-content/uploads/2016/07/S-Plan-Zone-ValveNEW-1.pdf

s plan central heating- http://www.electriciansforums.co.uk/wp-content/uploads/2012/02/S-Plan-Twin-Zone-Wiring-Diagram.png

y plan central heating-http://www.electriciansforums.co.uk/2012/02/y-plan-biflow-central-heating-system-electrical-control-connections-and-wiring-diagram/

I don't do new builds so my experience is confined to refurbishments.....

I tend to make an allowance depending on what is planned to be installed THEN make very sure I work closely with the plumber and builders.

Multi underfloor systems can be very tricky...

Sorry if this isn't helpful

If you mainly do new builds and full refurbs etc then imo you should really learn heating wiring. It's not that difficult really. You will have to find out what kit the plumber is supplying, how many zones, secondary return hot water etc then base your 1st fixing on that rather than a generic diagram. I didn't really touch many heating systems throughout my apprenticeship so taught myself it...You could always go on a course like this Wiring & Controls Course | Mr Combi Training - http://www.mrcombi.com/wiring-controls-course/ I would stay away from the likes of the training that some of the leading manufacturers offer as they will obviously be all about their own products.

Here's a few pics of jobs I'm on ATM...ones a polyplumb setup and the other is going to be Honeywell evo home. None of these two would work if you 1st fix it using a generic Y or S plan drawing. For example the pic with all the pumps has ground floor UFH, 1st floor rads, second floor rads, towel rads and hot water. There's another pump which is a bronze/stainless steel pump for secondary return then there's another two pumps on the UFH manifolds. In total there is 9 pumps including the one internal to the boiler.

Slightly disagree with leesparkykent (feeling brave!). I attended the Honeywell course which was £40ish (including a cracking lunch) which I found to be great.
They run their courses at different venues around the country.
The main thing they manage to get accross really effectively is that it is just a series of switches (except three port valves), and to deal with one section at a time in a logical manner. Even the plumbers got it!

Hi - I'm liking the array of pumps - maybe should've been a plumber

.
Can I ask a question? It seems clear the pump in the service boiler probably won't have the oomph needed for that job. I understand the one in the Boiler, one for UFH and the one for HW recirc. But how do you know when CH needs its own pumps? (and can't rely on the boiler pump). I've been in places that have 20+ rads on the boiler pump and it doesn't seem to heat very well and I've thought this may be the issue?

Looks like a very neat consumer unit install in the left of the picture.

been doing a bit of reading this evening- doesnt look too tricky- like everyone says- just a load of switches.

In terms of 1st fix- majority of components will be in a cupboard where the wiring centres will likely go anyways- then just a case off throwing in 3core+e to CH/UFH stat(s)/programer(s) and boiler- going back to wiring centre location.

then worry about the 2nd fix when it comes to it- and just wire by numbers with the diagram in the book.

J.C.E, once you understand how the motorised valves work in terms of each zone they control [or hot water for that matter] you'll find it easy. Feeds generally go from programmer to stat/s to valve which then drives open allowing heated water to flow in that particular zone,then once open a microswitch closes within the valve head which will be the switched live to the boiler.
