Underfloor Heating Temperatures and running

[JamieB3009]

Hello,

I have recently had wet underfloor heating installed round the full ground floor and I am still trying to get my head round how best to run it. At the moment, each of the UFH zones is controlled with a Hive thermostat which monitors room temperature and then cuts the UFH in and out as needed to maintain that temperature. At present, I have the largest zone (kitchen diner open plan) set at 21 degrees and it is maintaining to this day and night. It strikes me that keeping it at this temperature all night and day is a bit wasteful as I'm out the house most of the day and in bed during the night. I have read that the most efficient way to run the UFH is to have it on all the time - I assume this means like the way I have it now (on manual just topping up the temp). Given the concrete takes ages to heat/cool, would it be better for me to have the temperature drop to about 18 degrees overnight and during the day or would this be more inefficient?

Thanks,

Wet underfloor heating is typically run with a desired temperature and a backset temperature of normally 4 °C below desired temperature. So it's normal to reduce temperature overnight and in day if no one in properly.
