£7.37 smart meter reading after 4 hours?

[Pumpkinsandhotchocolate]

Hi everyone! We moved into our new home yesterday and had the heating on for 4 hours. Before this, I plugged in the left behind smart meter and after the 4 hours of having the heating and hot water on, it came to £7.37! I know energy bills are high right now, but surely that can’t be right? House is 300 years old for context.

Is the heating electric and is the immersion heater on?
It does seem quite high we use £3-5 a day

Sounds high. We use about 3 to 5 £ a day currently. I will add that our smart meter monitor isn't 100% accurate

Yes it is electric and the immersion heater is on. Does an immersion heater cost more?

Yes the immersion heater is 2kw and it will be cutting in and out constantly to keep the tank of water hot. It needs a timer and on twice a day.
Electric heating is the most expensive
We burnt through about £75 of electric in the first few days when we moved but it’s just about under control now because it’s been turned off!

I turn my imersion Heater on every other night over night. There is a switch near mine.

Ah I see, thank you so much! Is the timer on the normal control system? My immersion heater just has an on and off switch?

The immersion is just an on off switch unless you have a timer fitted

Electric heating is a lot more expensive than gas.

We put our heating for half an hour last night and it heated the immersion two. It went from 5.58 to over 8.50

Well a lot of detail missing in your post, but if you are on electric doesn't surprise me. The immersion heater will cost, but it is probably the heating that is really racking up the cost.

£7.37, you used about 21 kWh if you are on the cap tariff (0.35 p/kWh).

Last night to heat my house from 14 to 18 degrees C (3 bed) with gas was about £1.50.

Is your whole heating system electric?
What temperature was your thermostat set to if you have one?

I would only put the immersion on shortly before you need to use the hot water and wouldn't leave it on for hours at a time

i have my immersion on 24/7 but I have E7 and the usage overnight (for everything - so devices on standby, my immersion and the fridge freezer and I guess the router) is 1KW. This leads me to say that keeping the water hot is not what’s expensive but reheating it after a bath for example uses up 4 or 5 Kw.

I have electric heating, a wet system and this is run from a 6Kw boiler. I never turn it on if I can possibly avoid it. Very very occasionally if I’m coming back after weeks away in winter. It’s on a frost setting and turns on if the temp falls below 5C. But is £3 an hour to heat up the house from cold, so really really expensive to use.
