DIY UFH should I attempt?

[mordzy]

Hi All.

Im currently doing as much as I can on a extension. Im looking to install some UFH and have laid 100mm celotex on the floor slab ready for the UFH pipes.

The space is approx 90m2 with 3 rooms. Bedroom + ensuite and a living room. Ive watched plenty of videos and laying the pipe looks quite easy with the plastic clips into the celotex.

Ive had a number of quotes ranging from 3 - 5k with a DIY kit being approx £1500. Is it reasonable to Lay the pipe yourself and ask a plumber to quote to pressure test, fill and bleed the system for me? and would that be a days work?

Im just trying to work out if the hassle factor and potential of me getting it wrong is worth the saving I may make?

In general,people are very wary of doing half the job,a major factor being,if there is a fault,who is to blame and stands the warranty.

Pressure testing and filling it is surely the easiest part of the job!

It is....The standing of the warranty for the home owners installed bit is the tricky bit

Fitting UFH isn't particularly difficult. I did mine. For pressure testing just connect the mains up and have a gauge on the manifold to see that it stays pressurised for a few hours or days. Leave it pressurised whilst the screed is being done. if it's going to be a while (months) before it gets connected up then putting a bit of biocide in is smart just to stop anything growing in there.

Pressurise it with air.
