Even cheaper than a water hammer arrestor, hammer relief valves are also easily installed on the taps that may be causing the water hammer – like the washing machine and dishwasher. High water pressure is commonly associated with water hammer, so you can also put a pressure-limiting valve at the meter for a whole-of-house fix.

An insulation layer can be installed over the sub floor prior to the installation of the hydronic pipes and the screed bed.  This provides a thermal break between the sub floor and the heated screed bed ensuring most of the heat generated will be radiated up into the room above.

Hydronic screed heating is suitable for large areas (80 m²+) and requires a sand and cement bed on top of the pipe. The minimum depth of the screed bed is 50mm. Screed installations have a faster response time than in slab installations, as the pipe is closer to the floor surface however, they do not have the same ability to store the heat to provide thermal mass.

Comfort Heat provides technical diagrams, electrical loads and helpful tele-support for a seamless installation. Your project manager will need to coordinate with a licenced electrician, plumber and concrete contractor to ensure all trades have the specifications they require.
