ᐅ Experiences with gas or air-source heat pumps?

Hello experts,

one of many questions: What is more economical, an air source heat pump or a gas boiler? It’s just one of many points we hardly understand.

We were considering a photovoltaic system with an air source heat pump, but it seems clear that usually, the sun shines the least when you need heating the most.

Is the good old gas boiler actually more economical after all?

Thanks!

Are you sure you have read the tariff conditions correctly? It took me some time to realize that you cannot use 18 cents, as this applies to the dual-rate metering (18 cents at night / 25 cents during the day). With separate metering and a single-rate tariff, I am charged 21 cents for the heat pump. And only if I also get my household electricity from the local provider do I receive a discounted meter price (€66/year) for the second meter.

120 € basic fee
On average 17.8 cents (?)
3000 kWh therefore costs you: 654 €
3000 kWh costs me (household electricity): 744 €
For 2000 kWh (more our estimated consumption) it is 496 € for me and 476 € for you.
Unfortunately, I do not have your terms.

That’s actually a base fee of €119 (about $130) and not €4.20 (about $4.60) per month, right?!

But the two-rate tariff prices are really good; you just have to set the heat pump correctly so it heats more at night.

Today I read an interesting article on Welt: "The expensive madness with heat pumps"

Don’t always trust the expert image

The article is total nonsense again... he “still doesn’t know what actually went wrong,” big mystery... the poor simple man suffers under power-hungry lobbyists or, even better, the government.
It gets worse!!! Soon Merkel herself will come and remove the gas heating system and leave an air-to-water heat pump in the yard – those who vote green will even get an air-to-air heat pump.
Then the fairy tale begins... the factor 1.8 is divided by the COP... the typical factor would be around 0.8 – that would mean a COP of 2.25, or am I mistaken? Good grief, how can anyone spread such populist, unresearched nonsense.
It goes on: “In one case, the performance of a heat pump was so poor – you might as well have heated the house with an immersion heater”... in another case, the car emitted black smoke because it was burning oil... still, not everyone demonizes the car or crowns the new pope.
And finally, the logical connection between electricity price development and user behavior is made – the only thing missing are asylum seekers or alternatively a nude photo of Miss Vaillant, then the article might have made it into the right tabloid as well.
