Installing A Heat Emission Plate (HEP’s) System
When it comes to UFH on ground floors, this tends to be done by embedding pipe into the screed. And providing it is done right, you have an extremely efficient system. However, more and more people want UFH throughout their home meaning incorporation of underfloor heating on (normally) a suspended timber floor. Many systems can do this, but this week we are covering heat emission plates.
Things to know when selecting this system.
- You want to try and select the thickest plate you can (the more aluminium, the better the heat transfer). You can generally ask your supplier for thickness for the plate. You need to be looking at 0.5 mm plates – any thinner & the transfer is reduced.
- The centres of the joists are important if selecting HEP’s, they need to be uniform and they cannot be an engineered type of joist. You are required to notch the joist at the end then past the pipe through.
- The plate size needs to match your joist (the most common size is 400mm between joists) and the plates should be slightly shorter, this is so the HEPS do not overlap and cause noise.
