mine is 21 degrees which is moderate - ie comfortable for men and children but a woman might need a jumper.
keep it on 24/7 the way God intended.
I'm discovering these boards are full of skinflints who install expensive systems and then sit freezing in the cold.
Cannot understand it.
The problem with most oil boilers running UFH is the temperature they run at. Most oil boilers are mild steel and have to run at 60c. UFH needs only a low temperature so you are heating water in excess all the time.
sfag,
for UFH to be working 'correctly' and at best efficiency....
it should heat up a thermal mass slab at night time and this slab is supposed to release the heat during the day. there maybe days in winter you do require it on at longer times, but if you have it on 24/7 all year round id seriously quesion
1. how its set up
2. if the construction of the house is suitable
3. how much degree of control you have with it
Seems like some folks have their thermostats in the floor from reading the above - I thought they had to be in the room on the wall?
FWIW. More and more I've come across ufh systems that havent been wired correctly and as result people think they aint working correctly. The wiring is cruical.
Mine was wired incorrectly and it constantly ran heating and cooling the water evey alternative minute - A disaster.
A friends was wired incorrectly and his wood pellet boiler generated the heat, sent it round in a loop, skipped the rooms, and never fired down.
With a gas boiler the boiler will keep the room tepid by using a trickle of gas when its warm as opposed to a gigantic blast used to fire up when the house is cold. With my correctly wired boiler keeping it on 24/7 cost no more than running it on radiator style timings.
I even moniter the effect of switching the heatin off for a long weekend and then reheating the house on the evening that I returned. I compared this with leaving it on for a full weekend. The cost was the same. My boiler is a gas glowwarm.
I'd say observe your systems and count the meter units and take other opinions.
UFH systems generate a max of 45 degrees of heat to the floor and that will be cooled down before the water completes its heat. Once switched off surely there is no way the floor can continue to heat your house all day?.
sfag...
This concrete screed then uniformly releases the heat slowly into the room throughout the day. This is why the system is essentially dependant on construction. You say your slab cools after 2 hours, id be seriously worried about your construction.
This means UFH floors have to be insulated to a greater degree than most roofs!!!!!
I cannot feasabily see how 4 to 6 inches of floor slab dept can emit heat all day. Theres nothing magic about that stuff. Its just sand and cement (I'm excluding easy screed here). My floor insulation was regulation standard which I believe was 60 mil hd (kingspan). Again that stuff does not work miracles. But if you say it works that way for you I suppose I have to suspend my disbelief.
It doesent get completely cold within two hours but it stops emiting sufficient heat.
As a matter of interest my gas bill last year was 2600 (hob and water included but they would amount to about 400) .
The house is 4000 sq ft excluding an unheated garage.
One side of the house is all glass and one room is 20ft tall.
I adhered to regulation on the insulation and oversaw the build myself.
The glass has gas and e-coatings.
Do you reckon I'm doing well on the bill or poorly - I appreciate the comments
