Underfloor Heating Heavy Electric Bill
14 Answers
Hi hoping someone can advise.
We have a house (electric only no gas) and the usage is more than FIVE times what the national average is for an electric only house if this size.
We tested the meter (it’s fine) and we tested the distribution board (ie turning on / off each breaker switch till we found what was pulling the power)
It is the definitely the underfloor heating (we have it in every room). I spoke to manufacturer who told me that the anticipated usage for our sort and size house etc is 0.14p per hour. Ours is 0.73p per hour !!! The power continues to be pulled even when the room stat is set to heating off mode (tho it does reduce substantially in this mode).
We’ve now turned off all the underfloor heating at the board. But are so cold (it’s our main heating source).
We are at a loss as to why this is happening. We clearly can’t afford this!
What could be the fault? I’ve hear of electricity “leaking “ due to faulty wire etc. But - we have 3 different breaker switches for different parts of the underfloor heating and each is having similar readings so can’t helieve each room could be faulty?
We are 2 people in a 4 bedroom house. We tend to set the floor temp 18c - 21c.
Brand is: warmup Electric underfloor
Stat type: warmup wireless 4ie (or something like that ... I forget the exact name).

We don’t have all rooms on. Literally about half of the house was set to heating off (but we discovered still pulling some power) and the rooms we do use often were set to 18-21c (average depending on time of day etc). Don’t have very high ceilings. We do have wooden floors in most rooms with tiles in kitchen, utility, dining room.
Could it be wired up wrong? Though surely that would trip the board?
Also why does it continue to pull electricity even when set to heating off ? (It is less electricity but still significant)

How about checking the usage of each room individually? That may narrow down the problem or identify a part of the circuit that is pulling a load even when off. I agree that there is something amiss. Is this a new build or a newly installed system? If so you should have warranty protection. If not it is obviously worth getting it checked out. Another though..... is there a previous occupant that can verify that the system has operated efficiently if you are new to the house?
Hymie when our underfloor heating is turned off at the distribution board our consumption averages about 6p per hour when (obv more if we cooking or washing machine or dishwasher on) when u/floor heating on it shoots up dramaticallt. Manufacturer tech team said for our size / type house they’d expect the u settlor heating to use 14p (average)
You raise a good point. I've not got the figures handy to check expected house heating costs, but maybe the manufacturer was/is trying to sell the system and being optimistic regarding running costs ?
0.73 x 16 = 11.68 if you leave it on all the waking day
x 90 = £1,051 a quarter. No, still seems high to me. Even if you only had it on 8 hours a day it'd be £525; well maybe.
I guess if you only heat 3 rooms it comes down to manageable. Unsure it's near 5 times the average though.

Talking about the cost is really a secondary thing, the primary focus should be on the actual amount of energy (kWh) being consumed to heat your house (charge rates vary considerably). Also, the question is whether you have intermittent heating or continuous heating - comparing continuous heating with national statistics where intermittent heating is the norm will always lead to frustration, your temperature levels are quite possibly different from what the statistics are based on (low levels of average heating in the UK). Finally, how well the house retains the heat is of enormous importance. Underfloor heating through wooden floors is somewhat inefficient (certainly less efficient than, say, with tiled floors) as wood is a mild form of insulation and your heating elements are to a degree insulated from the air above the floors (assuming heaters are below the surface material).
