Adding heating when a Tadley ground floor is opened up
When an original floor comes out, or a rear extension goes on, the ground floor is open and the build-up can be designed from scratch. That is the most economical time to add wet underfloor heating, because the insulation, pipes and screed all go into the new floor rather than being built on top of the old one.
Pipe cover is the figure that drives everything else. With liquid, we leave 25mm or more over the pipes, making the floor about 45 to 50mm in all. Sand and cement needs closer to 45mm of cover, giving a thicker floor. In a post-war Tadley house, the new floor must still meet the existing doors and the bottom stair, and that gap can settle which screed is used. Floor height is often the tightest limit in a retrofit, and we measure it before recommending anything.
With no air trapped around the pipes, a liquid floor passes heat to the surface quickly and evenly. Sand and cement is worked around the pipes by hand, and it is the right choice for a heated shower room or where a cement base is needed. The two are compared side by side in our guide to liquid against sand and cement.
Pour day starts with our check of what lies under the pipes (insulation, membrane and the edge strip round the walls), and the pipes should have passed your installer's pressure test by then. If the insulation and membrane are not down yet, we can supply them.
Bringing a Tadley heated floor up to temperature
A new heated floor needs a patient start. Calcium sulphate can usually have heat put through it about 7 days after pouring. With sand and cement, keep the heating off for 21 days or more. From there, run it low and step it up over several days, as set out in the heating manufacturer's commissioning schedule. Going to full heat on the first day can crack the floor.
Used properly, the heating helps dry the floor, which shortens the wait for the flooring fitter. We hand over written guidance on the warm-up so the heating engineer, the builder and the homeowner are working to the same plan.
A heated rear extension often opens into the existing kitchen, so the join between old and new floors needs thought before the pour, not after it. Where the older floor stays and is simply uneven, levelling compound can bring it into line with the new one; see floor levelling in Tadley.
