ᐅ Your current heating consumption

It's not about oil. It's about a house from 1979. That's what I mean by progress being slow as a snail. Because six thousand liters is actually okay for 430 m² (4,630 sq ft) as an annual consumption. Oil has already almost cost one euro per liter, very volatile. I also wouldn’t choose oil for a new build and won’t do so. But in new construction, we will hardly manage to cut our heating costs in half.

The 430 m² (4,630 sq ft) wasn’t entirely living space, right? And to what extent the "usable or commercial area" is heated to the same temperature, I of course don’t know. But for example, I wouldn’t heat storage rooms to 23 degrees Celsius (73.4°F)…

Hello,

I’m having trouble following your calculations:
You claim your heat pump will produce 60,000 kWh of heat for 2000 €. A quick calculation shows you can buy about 8,000 kWh of electricity for 2000 €. That would mean a seasonal performance factor (SPF) of 7.5, which implies a coefficient of performance (COP) around 9-10 on average over the year.
Either you’ve found a way to get very cheap nuclear power from France, or you have a perpetual motion machine as a heat pump, or you’re tapping into a hot thermal spring...

More realistically, I would estimate the electricity consumption of a heat pump producing 60,000 kWh of heat at a minimum of around 15,000 kWh. That would translate to roughly 4000 € in electricity costs.

Or am I missing something here?

Best regards,
Andreas

In our area, electricity for heat pumps costs around 18.x cents per kWh, so for 15,000 kWh it’s less than 3,000 €.

Wow, that’s cheap, which of course changes the entire calculation. When I looked into the question of gas versus heat pump about 1.5 years ago, only heat pump tariffs were offered around Nuremberg that were almost as expensive as regular electricity. Some neighbors even paid more for their heat pump tariff than we do for our household electricity.

Seems like things have changed...

Of course, this only applies if you also purchase your household electricity there. Since it is around 25 cents gross, you can definitely manage with that...

Where can you find prices like these?

I checked for my location: the red energy supplier offers heat pump electricity for 18.35 cents, without requiring me to get my household electricity from them.
