jayc89 Posted March 15 Share Posted March 15 Assuming you know the heat loss and the mean water temperature of the system (open loop, no mixing), is there a mathematical formula used to calculate the most efficient pipe spacings? Assuming 16mm PERT. I've seen nomograph's used to work it out, so presumable there is a known equation? Link to comment Share on other sites More sharing options...
Andehh Posted March 15 Share Posted March 15 I'd opt for closer spacing to speed up heating and run a lower temperature!! Link to comment Share on other sites More sharing options...
JohnMo Posted March 15 Share Posted March 15 Once you get below 15W/m2 there basically nearly no difference in flow temp between different centres. Something like 2 or 3 degs between 300 and 100mm centres. As mentioned the only difference is response time. With thick screed the response time is many hours per 0.1 Deg anyway. So I just did 300mm centres. Easy to install, 8 loops over a 195m2, batch charge overnight on E7 at 35 deg flow temp. Link to comment Share on other sites More sharing options...
