underfloor heating?

[bungarm]

Just wondering what you guys think of 'wet' underfloor heating..is it okay to consider or a definite no-no in your opinions.

I am aware of the possible leakage problem, just want to know if there are any others, for instance, does the size and output of the boiler matter? I'm guessing it does...we have about 22 sqare metres to warm up...) We will be doing away with all the downstairs rads bar one (tiny one near front door) but keeping all 5 of the upstairs rads, and replacing our 11 year old boiler too.

We also want to lay the pipes under a solid wood floor...any comments about this? Any info would gratefully received, like how deep should the pipes be laid in concrete, or can they just be clipped to the existing concrete floor.

Apologies in advance if this is the wrong forum for this...if so, could you guys point me in the right direction? It seems really difficult to find any ifo on this...thanks in advance.

Underfloor heating is a speciality and even the best has very different characteristics from rads and needs seperate control..

I would not recommend DIY underfloor until you fully understand and accept its limitations.

We have just done our first system in a farmhouse, works brilliant on the tiled floors, not as efficient where the wood has been laid. You still need to screed under the wood floors. but look on the polyplumb website, this was the system we used, and they were so helpfull i.e. planning, even can arrange as we did for their engineer to come and work with you for a day

Check your heat losses (via walls, windows, ceilings, etc) against what you will get out of the floor, allowing for carpets, etc. In a retrofit situation, you may well find that the floor will not give you enough watts.

I've read the OP several times and I can't find the part that asks for an Agile recommendation.

It's not that much of a specialism these days - there are many companies who will sell a complete kit of parts, including instructions.

Laying the pipework is not a difficult job, and the plumbing job is not extensive or difficult.

Would not recommend it as a DIY job without basic training... digging up floors is gonna be a big hassle.
Nuheat are a good choice (www.nu-heat.co.uk) ... different heat outputs required depending upon your choice of floor covering... thick carpets and underfloor is no good... excellent for tiles and pretty good with wood flooring but Nuheat will need to know floor covering before designing system.
