Hello everyone,
we are currently planning our house. One of the first questions from suppliers is always about the "heating method."
So far, I have mostly shrugged and said "gas heating."
Over the weekend, one supplier recommended air-to-water heat pumps. Until now, I didn’t even know such systems existed.
I’m trying to educate myself a bit and found the following model from the company "Stiebel Eltron":
WPL 13-23 cool
The description says it can be used for both heating and cooling.
Now my question:
Can the cooling function be understood like an "active" air conditioning system (performance of a split air conditioner), or is it more of a kind of "pseudo cooling" that lowers the building temperature from 35°C to 34.5°C (95°F to 94°F), meaning almost no real cooling?
What do you think of this technology in general? (I have only lived in houses/apartments with gas heating so far)
(Warm in winter with gas, cool in summer with a separate air conditioner)
I want it to be warm in winter (without having to wear a thick sweater indoors) and cool/cold in summer.
Until now, I have never really looked into energy efficiency.
In winter, I prefer a (very) "warm house" and rather pay extra than be cold and get 100 euros back.
With friends and acquaintances who have installed "new" technology, I often get the feeling their house is (too) cold in winter. (You don’t freeze, but it’s not comfortably warm either.)
When they visit us, they almost always say, "Oh, it’s so nice and warm here."
Best regards
Bubb

Hello Maxim,
good to hear.
By stove, do you mean a fireplace? Yes, I would like to have one too.
Do you have the price for that Mitsubishi model?
I believe my budget would include a heat pump up to €11,000 (approx. $12,000) including installation.
As an example, I was shown Viessmann and Heliotherm (split system, Basic Comfort).
I just found a Mitsubishi Zubadan 11.2 kW for €12,300 (approx. $13,400) and an 8.1 kW for €11,200 (approx. $12,200) on billiger.de. That’s roughly in the same range.

Hello Wallace,
about €50 per month is realistic. We are also building a KfW 70 house this year, and based on my calculations, our heating costs will be around €50 per month as well.
Not all heat pumps require an electric heating element; for example, the Mitsubishi Zubadan does not need one down to -25°C (-13°F). Of course, you need to design the underfloor heating system to operate at the lowest possible supply temperature, which will further improve efficiency.
Regards,
Max

Sorry Wallace, the last two messages (yours and mine) didn’t show up for me, so I sent the same message again.
8.1 kW for €11,200 (about $12,000) seems overpriced to me, especially since the site is called billiger.de.
Please check eBay or, if you have contacts, a specialized wholesale supplier in refrigeration technology.
I found an 8 kW (split system) for €9,000 (about $9,700). You need to be careful, there are differences with Mitsubishi models, for example whether a hot water tank is integrated or not.
Best regards
