Project
hydronic underfloor heating of the villas , located in the bathrooms . The hot water flowing through the screed heats up the screed to a temperature of about 28 ° C , giving a heating output of 70 watts per square .
Pool heating : The hot treated water is also utilised to heat the pools .
PEX piping laid on top of foam for the underfloor hydronic heating system in the bathrooms . The next stage of the process would be a mesh layer and screed on top of the piping system , and then the tiles .
Heated towel rails : The hot treated water is also sent to the heated towel rails in the bathrooms to warm up and dry the towels .
Villa pools are heated through heat exchangers .
The pool is heated up by the hot treated water sent to a Bowman shell and tube heat exchanger . The treated hot water flows over the tubes in the heat exchanger and the pool water flows through the tubes in the heat exchanger . This allows us to be able to heat up the pool water without having to mix the pool water with our treated hot water . The Bowman shell and tube heat exhangers are fully serviceable and have probe sockets to measure the temperature of the pool water flowing through it .
Bowman heat exchanger
Potable hot water : From the insulated trench , the potable hot water is branched off the ring main to plumbing manifolds . The plumbing manifolds are located at all bathrooms and kitchens .
