An issue came up today though is that not sure how to set up a circuit for the two towel rads we're having. Here are the different factors we're juggling: The UFH will need to be kept fairly low temp, because our engineered floor cannot be exposed to a subfloor that is hotter than 27 degrees. So I'm guessing we will run the UFH at 30C - though not sure how to calculate what temp to give 27? And presumably different rules apply for heating screed on a ground floor than for heating a non-screed system on the first and second floors. The hot water cylinder I understand needs to be at 60 degrees minimum to avoid legionella. Our plumber thinks this is a waste of energy, but I don't see a way around it, although I know some people just heat it once every so often to sterilse, but either way the temp of the UVC will be much higher than the temp sent to the manifolds won't it? Then what to do about the two towel rads. Presumably these are fine at 40 to 45 degrees, but that is higher than the UFH and lower than the UVC. Or can each UFH manifold lower the temperature of the water it is getting from the boiler? We are not having buffer tanks for the UFH because we've gone for a broad range modulating boiler and a low loss header instead.
