Ämne: Annual consumption in Stockholm

[ja100]

Hello, sorry for English, jag kan bara pratar liten men inte om ev språk!

I am looking to find out some average yearly consumption metrics for households in Stockholm so I can do some comparisons for ours.
We live in a 150 sq metre villa, radiators upstairs, underfloor heating downstairs, 4 occupants, we have an air/water heatpump that provides heating and hot water. Just to mention we have a ventilation system that takes air and moves it around through air ducts, it particular works well in the basement (half the villa) to keep the air feeling fresh.
In winter we tend to keep the house around 21 degrees as lagom, I think around 20 is best as prefer to wear jumpers etc inside in winter but we keep it a little higher.
We use around 11,000 Kwh annually, it was 11,263 for 2023, and 10,776 for 2022, I can envisage that 2024 might be a bit closer to 12,000 as it was a really cold winter and now we have a new occupant that wasnt around in 2022 and half of 2023.
Speaking just socially to neighbours I get mixed reactions, some think its very low and theirs is much higher, some think its quite average for the area (but I have no concrete understanding of this or of their set ups)
I have no idea if that is good or bad in comparison to other similar set-ups, and would like to know and so I can see if I an improve it (if possible). Is there any statistics I can read online for example or anywhere I can read about modern averages?

any would be great thanks!

Hi!
There are so many factors that affect the energy consumption, that statistics easily become misleading.
Is the house freestanding ? (no terraced house)
How old is the house?
What size of heat pump?
Do you have heat exchanger in the ventilation?

And of corce, how much household electricity do you use?
Any electric car?
Any cabin heater?

[ja100]

House is freestanding yes, not connected to any other house.

It was built in the 1930s.
8 kw
Yes there is, it is 1.3kw so quite minimal ( I think?)
Household electricity? Do you mean a split between heating/ hot water and everything else (tv, appliances etc), I’m unsure how I can get that information?
No electric car
No cabin heater.

Short answer
4 people, 150m2, from 1930.
11.000kWh is okay, it's good but not great☺️

[ja100]

okay so around average with my set up?should I be looking for ways to maybe make it around 10,000 or lower? thanks!

I would say its close to great.
Ventilation does need som power input just for the fans, and heating a old house can be quite expansive, but even here, there are a lot of ifs and buts, new windows and doors insulates much better than old for example.
If windows and doors are old, you might be able to save maybe 1000 kWh/year if you change them.
Other tings that can be energy thieves are old lighting fixtures, old LED fixtures often had transformers in them, that gets hot due to inefficiencies, Halogen bulbs are also much worse than modern led bulbs.
Putting out light in rooms not used can also save a bit.
When you are at your level 11000-12000 kWh, its just the small things that you need to focus on.

If the FTX system is old, you can save more if changing to a modern, but payoff-time will be very long.  (Same with changing windows and doors)

[ja100]

The windows, I believe are quite old (maybe not 30s) but the window frames are particularly old, we are wondering about replacing the windows gradually from double glazed to triple glazed.
Likewise, the heatpump we have had for 3 years now and it has worked remarkably well (for 7 months before that, when we moved in we only had electricity and consumption was silly), but I wish I had gone for ground source then instead. I didnt know anything about heatpumps or groundsource though as we do not really have that in the UK (where I am from). The heatpump possibly seems a little under what we need also, as on very cold days or when its very humid outside it sometimes has to dip into electricity to get heating water.

But this fills me with a bit of hope though, that 11k is good or borderline great. If I could get below 10k one year I think I would be very happy, but that may be more due to it being a warmer year for example !

Make a paretho of all your consumtion, then try to improve all by 20%.
One dolares earned is not one dolares, its only half dolares because of our taxes, but one dolares saved is really one dolares! ☺️
Learn your system and you will find savings for many coming years 👍👌

For that old house it is really good.
I can say that the heat exchanger for ventilation is probably working good and so is the heat pump.

You can compare to my house with a geothermal heat pump
Size 130 m2 and built 1970, I use around 11000 kWh for my house and is fairly economical with electricity.
I live in Sundsvall.
