Heated extensions on Bournemouth's post war and inter-war houses
Homes built between 1945 and 1972 make up 19% of Bournemouth's housing, and with the inter-war homes they form a large stock of houses across the suburbs. A rear extension on one of these houses is a natural place for underfloor heating, because the new floor is insulated from scratch and there is no old slab to work around.
The screed does two jobs over the pipes. It spreads heat evenly, and it carries the load of the floor above them. That is why pipe cover matters. Over the pipes, pumped liquid has to clear each one by 25mm or more, leaving an inter-war extension floor somewhere near 45 to 50mm deep. By hand, sand and cement has to bury the pipes under something like 45mm, so a Moordown or Charminster extension done that way ends up thicker and heavier.
Liquid screed has an edge here. It flows around each pipe and fills the gaps, leaving no voids to slow the heat down. Hand-laid screed can do the job well, but compacting it around the pipes takes more care. Before pouring we look over the edge strip, membrane and insulation, and can provide any of them; the insulation and membrane service has the detail.
Your installer should have every pipe clipped and pressure tested before our visit, and it is wise to leave the circuit pressurised while we pour, so a leak would show straight away. For more on the pumped option, compare liquid screed in Bournemouth with the traditional one.
Retrofitting underfloor heating in Boscombe and West Cliff villas
Adding heating to an older Bournemouth house is a tougher job. Victorian and Edwardian villas around Boscombe and the East and West Cliff often have little depth to spare: lifting an old solid floor to add insulation, pipes and a new screed can raise the finished level against doors, stairs and thresholds. The lower build-up of liquid screed often decides whether the new floor fits at all.
Where the old floor is timber, the question becomes whether a screeded system is right, and that is a conversation for the heating designer and us together before anything is ordered.
After the pour, commissioning should be gradual. Heat can usually go into a calcium sulphate floor from about 7 days, but a sand and cement one in a Boscombe villa wants 21 days at the least. The temperature is then raised in small steps, which helps the floor dry evenly without cracking. For day by day timings, the guide to screed drying is worth reading before you book the flooring. Where an old villa floor has to be dug out and relaid before any of this, read about relaying with sand and cement.
