Pipe spacing The most common spacing between each pipe run is 200mm. However, this will vary in some instances both wider and narrower spacing, based on the heat loss of the area. Heat loss will be adversely affected by large areas of glazing, or poor insulation values.
What is the maximum length of pipe for underfloor heating?
The maximum loop length of 110 m must be used in all installations. It is not advisable to make the loops longer than 110 m. The reason for this is due to the head pressure from the pump, the pump used is only capable of pressurising water through 110m of pipe.
How can I make my underfloor heating more efficient?
For an efficient system and quick response times, set your underfloor heating temperature to 16°C in “off” periods. This will result in a quicker warm up time as the heating system needs to supply less energy.
How do I calculate pipe size for underfloor heating?
To calculate how much pipe is required, you will need to divide the area of your room(s) by the pipe spacing you require. What should be the maximum circuit length? To avoid excessive temperature and pressure drops, Uheat recommends a maximum circuit length of 100m (for the 15, 16 and 20mm pipe).
Can you cross underfloor heating?
Never Cut or shorten the heating cable! Allow heating cables to touch or cross over each other. Connect underfloor heating mats/cables in series! Multiple mats/cables must always be wired in parallel. Power up the heating system while coiled or exposed to air as this will cause the heating element to burn out.
How do you trace underfloor heating pipes?
To correctly trace underfloor heating, the user should turn on the system and hold the thermal camera steadily pointing at the floor once it has fully warmed up. Temperature directly above pipes tends to be at roughly 26˚C compared to an average floor temperature of 18˚C.
