Night “set-back” and under floor heating?
Screeded (and concrete) floors, when heated by under floor heating, retain heat for many hours, which means night set-back is ineffectual. However, this is UFHs great comfort strength; the floors relative slowness to cool down ensures that indoor comfort is not affected by rapid temperature falls from outdoors. If you are going away (e.g. on holiday) the set-back feature can be effectively used. Wood suspended and floating floors have much faster reaction times, so with these structures night set-back can be used. Many modern homes in Britain and Ireland incorporate wood suspended floors for the first floor and above, so set-back may be useful for the bedrooms.
