Which BHK block heating power plant - costs?

Hello,

I am considering buying a "Reinhaus" from Reinhhaus AG and I find it somewhat difficult to estimate the heating costs. To me, the ongoing costs of this power plant, which is actually required for heating, seem quite high given that theoretically it should cover 50-70 percent of the plant’s electricity demand but you almost have to pay the basic supplier tariff for electricity.

It says as follows:

The heat price The energy supplier places the greatest emphasis on transparency when setting the heat price. The monthly all-inclusive price for the heat received is calculated from a basic price and a consumption price. The basic price includes all fixed cost components such as installation or purchase of the plant in the technical center, regular maintenance, operations management, upkeep, chimney sweep fees, and any necessary repairs. Maintenance of the heat transfer station in the ground floor register of your house is also included in the basic price within the five-year warranty period. Your individual heat consumption is taken into account in the consumption price. This also includes the network operating energy required to provide you with heat for heating and hot water production around the clock throughout the year. This is distributed among all consumers by relating the sum of the heat meters of all residential units to the billing-relevant main heat meter in the technical center.

For 5 megawatt hours of heating per year for a 145 sqm house, you are supposed to pay 50.07 basic price and 44.82 consumption price. So 94.89 €/month. Plus 19.22 for metering services. So 114 per month for some warm air. When I look via Check24, I come to 303.16 per year for the 5 megawatt hours + 100 maintenance(?) and 100 chimney sweep(?) or just under 42 per month, which is already an enormous difference for me. Even if you factor in a gas boiler that you replace every 20 years, with a 3000 one you pay an additional 12.50.

The "free electricity" that the community produces is then sold again at a hefty price. But here you can presumably switch to another provider.

Have I forgotten to consider something or are the ongoing costs simply significantly more expensive per year with the super efficient power plant? One naturally also wonders whether you should take out a 50 euro bigger loan and try to buy something else or whether the ongoing costs simply make the price unattractive again?

Well, you can't have everything. The egg-laying wool-milk-sow is not the Deutsche Reihenhaus either.
However, I can tell you, as I know the company, that they deliver overall good quality for the price. With all the particularities like WEG, BBKW, or similar.
These are industrially prefabricated houses with little room for special requests. But in terms of price, really good.

I would find the term "terraced houses" more accurately described as "vertical condominium" according to their concept. You only become a co-owner there and, unlike the classic floor-level condo, you have neighbors beside you instead of above or below you, and your garden share directly attached to the "apartment in terraced house form." Even with the outdoor cabinets for trash bins and leaf rakes, you can forget about individualism. A combined heat and power plant is only consistent in such a concept. As is usual in a homeowners' association, you practically have a "connection obligation." This concept fits for you only yes or no – but only this way does the calculation work out. Helmut or Erich, you cannot mix that.

I don't really mind being a WEG and I don't particularly want to express myself financially or artistically on the facade or in the garden. However, buying an A efficiency house but ending up paying double the heating costs, effectively paying like in an old building, I don't find so great. But I haven't completely given up yet and am calculating it with another a plus house where I would effectively come out cheaper by the estimated time of death. Because the association is so successful, you can almost assume that you still come out well. But as an ordinary consumer, it's difficult to calculate.

one could almost suspect that you still get off lightly.

Just pick some construction areas where building has already taken place (there are plenty of those) and ask the residents there.

I think you can save yourself that: anyone who doesn’t like this concept drops out early; and anyone who moves in there likes it. I get the impression from this provider that he has found exactly his target group in and with his niche - only those, but thoroughly.
