Underfloor heating temperature help

It sounded like electric and I think you're over analysing it (not meant to be patronising, it took me a while to get to grips with it). If it's on a timer, just set it to come on an hour or so before you need it to be up to temperature, whether that's one or twice a day. Don't worry too much about the temp setting, just set it to somewhere in the 30s. If it's less than 1kW as I suspect it is, it won't cost a fortune to run.

Thanks - over analyse -me? Fairly frequently:o

It has some sort of energy monitor thing too so I think I'll play around with that and see what it shows. If 30ish is what it needs to run at then I guess as long as it isn't guzzling electricity then I maybe just need to learn to live with it:)

how well insulated is your floor? we have electric underfloor heating in our new kitchen extension which is obviously very well insulated and our tiles are thick quartz.

ours does feel nice and warm, in fact i kick my slippers off and walk on it barefoot as it feels so nice. i looked at our thermostat today and it was set at about 18 degrees.

does your room feel warm? ours does.

love ours and wouldn't be without it!

Actually it's the total opposite ufh runs at a much lower temp than rads

Depends on the system. Mine measures the temperature of the tiles.

Really, don't see the point in that at all, it's room temp that matters. It's like strapping a thermostat to a radiator,

Only going by experience of the 3 systems I've fitted for others, all different makes but all used separate wall thermosats;)

The fact that you (op) are measuring floor temp and not room temp answers my question as to why you would want to heat the 25degs, I assumed you were talking room temp.;);)

Either way it should certainly feel warm to the bare foot

Maybe he's got his socks on??;)

On a serious note, even set at 25deg it's not going to feel very warm, it gets a little subjective. I'd suggest that the floor temp is checked with a thermometer at actual floor level if that's where the temp is being set, to check the correlation between system stat and actual temp

the only time i've really seen electric ufh in action was at a friends house where it was put into a basement bathroom, they said that it took them 4 days of it on very high to get up to temperature but once there it was easy to maintain the temperature, they said they used more units of electricity if they let it go cold and had to heat it up again - but can't confirm, i'll see if he can give me any hard data!

There are different systems. I'd be surprised at 4 days to warm up, unless it's been installed incorrectly (ie perhaps on bare concrete?).

Mine is the Warmup system and is designed to be laid beneath floor tiles, on top of the wooden boarded floor or on insulation board if it's a concrete floor. It's only a 600watt system but as I said earlier, it warms up in an hour or so. It is not powerful enough (and is not deigned) to provide primary heating for a room but it really does take the chill off the tiles. They are very definitely warm under foot.

I only run it in the mornings since we have our showers at a predictable time. It would cost a fortune to run all day for little benefit.

:rotfl:NOT if its electric :rotfl:

Someone threw a spanner in the works not saying it was Electric initially then mentioning the boiler settings

As a wet UFH system uses Blending/Mixing valves to control the actual circuit temperature, according to floor construction, I would still have the boiler setting Higher for quicker warm up of the whole system
