A simple underfloor heating layout system? Advise please!

[tamz]

Well at least nobody swore😀

Most of the underfloor systems i have fitted have required the pipework to be left at 6bar when screeded over, then dependant on what the screed is made of the temp needs to be controlled and slowly increased as to not shock the screed compound and cause cracking in the floor. I can only see one outcome to this situation.

Most underfloor manufactures will help with design and even produce drawings for you free of charge if you are buying there kit, when i have been unsure in the past i have requested them onsite for advise and they are happy to help.

Let us know how you get on?

You should have a secondary pump for the UFH and if using a combi you need to check MI's that you can have a secondary pump. So you're retro fitting of mani and pump idea if it doesn't work properly (which it won't) will go out the window if you can't have one on your particular boiler. Just do it properly INHO or not at all.

Many thanks for that advice, I will take note. Thanks

Many thanks for your advice.
I did infact fit UFH in one of the 12m2 ground floor rooms 8 years ago, with 50mm screed overlay. I just supplied it with the return on the last radiator in the system and it worked fine with no cracked floors etc.

I know you will ALL really really hate me now!

I am buying two proper manifolds now though; one floor the screeded flloor loops and one for the suspendend wooden floors, so I will be able to easily add a secondary ULH pump and mixer valves when it goes pear shaped. I'm going to fit inline TRVs in the bedroom loops to act as room thermostats.

many thanks

Mick

It's only hot water. It's only gas....

Hi Howsie For your reassurance, I am not going to fit the boiler myself, I found a nice chap from Watchdog!

I think all your trying to do mate is take the micky, listen to people that know, think the replys from the lads have been very ploite, dont push it anymore.

mick it takes some going to annoy the chaps on here,

its not like other forums as i have said in the past. Take a hint and call in some underfloor guys, of which I am not.

Hi Smillsey. Yes I do appear to have touched a nerve. I do really appreciate everyones advice. I will let everyone know how I get on (with whatever set up I end up with) when I buy a a boiler etc in a few weeks time. Although this winter will be the true test.

But strangely fitting for this thread!

what screed compound have you put down and what is the manufactures recommended drying timescale for the screed? these can be critical to when and how you commission the UFH. many screeds although dry and able to walk upon within a day or two take weeks and months to fully dry/cure.
