Does anyone here have underfloor heating? Does it cost a lot to run?

[PremiumPony]

I live at home with my mother and we share the bills. We have a visitor for the Christmas and New year. The first task my mother does every morning is put on the underfloor heating in the bathroom in anticipation for his shower. There were a few days that he didn't even go for a shower so it was on all day from morning til night. Then other days when he went for a shower only at night time and it was on all day from morning til night time after his shower. Then other days when he had an earlier shower and the underfloor heating was turned off earlier in the day.

I am dreading the electricity bill. I am being mindful of energy usage and if I turn it off because there's no need to have it on all day, she gets angry.

If you have a smart meter, the you can work out how much it costs.

For a small area it won't be that bad.

No, I don't have a smart meter unfortunately.

I turned ours off in our (small) bathroom - it was disproportionately expensive for the area it was heating! We are already paying over £300 a month for gas and electricity, and so I'm trying not to use energy unless it is essential.

(We are in a leaky 4 bed Edwardian house with 4 teens for context)

We have gas underfloor heating in the main living space and don’t find that expensive. However we’ve turned off the electric uf upstairs as that seemed to cost loads! So yes, we find electric uf heating expensive

Yes, concur with @DGPP - ours is electric UF heating....

I had electric UF heating in just the teeny hallway in my old house. The bills were astronomical. You’d be cheaper burning tenners.

I am anxious that anything that heats up that is going to cost and that would likely mean the underfloor heating too. It's electric underfloor heating. To be honest we very rarely use it. It's been years since it was on to be honest. We just done use it.

Now my mother has it one from morning til the guest has a shower and that could even be at nighttime or not. It could be 4 or 5 or 6 hours a day or even more. Last week after Christmas Day, the had a quite day in front of the tv and didn't plan on going anywhere and didn't need a shower but my mother still had the underfloor heating on in anticipation for him to have a shower.

I think if she wants the under floor heating on for his shower, she could just talk to him and see what time he wants his shower at and then turn it on for about half hlan hour before hand.

If I turn it off she's angry at me.

if we have it on in the kitchen (about 1 square meter) it costs about a tenner a day.
so it stays switched off.

Electric UF in kitchen. It is permanently switched off. It is too expensive to run for minimal benefit.

Who is this visitor?
In the scheme of things the cost of heating one small floor might not be that much extra.

Do you both own the house? Or is it your mother's house? If she owns the house then I guess she gets a bigger say in it, maybe?

Do.you split everything like repairs, maintenance, property tax etc?

We have underfloor heating in our breakfast room and a shower room. We leave it on low all the time at the moment, we have economy 7 so it is cheaper to heat at night when it is colder, and if it isn't switched off it more or less keeps its heat during the day rather than needing to heat up from cold. The (elderly and arthritic) cat gets shut in the breakfast room overnight, and the shower room is downstairs and absolutely freezing if not heated at all.
We are in the lucky position of not having to struggle to pay our bills at the moment, but I haven't seen any huge rise since we started to do this.

Wet gas UFH downstairs - excellent value - have to plan it carefully though as it takes a while to get going but can switch off as soon as the temp increases by 0.1 degree as it carries on getting warmer for a couple of hours.
Upstairs, electric UFH. Mostly off. Switch it on 1 hour prior to shower, with towel rad on at the same time.

Switch it off when I go for my shower. Costs about £1 hour.
