Hello,
I am considering buying a "Reinhaus" from Reinhhaus AG and I find it somewhat difficult to estimate the heating costs. The ongoing expenses of this power plant, which is actually needed for heating, seem quite high to me, especially since it is supposed to cover 50-70 percent of the plant’s electricity demand in theory, but you still have to pay almost basic supplier rates for electricity.
It is described as follows:
The heat price The energy supplier places great emphasis on transparency in heat pricing. The monthly all-inclusive price for the heat received is calculated from a fixed base price and a consumption-based price.
The base price includes all fixed cost components such as the installation or purchase of the system in the technical center, regular maintenance, operation 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 base price during the five-year warranty period.
The consumption price reflects your individual heat consumption. This includes the grid operation energy required to provide you with heat for heating and hot water production around the clock throughout the year. This cost is shared among all consumers by relating the sum of the heat meters of all housing units to the main heat meter relevant for billing in the technical center.
For 5 megawatt-hours of heating per year for a 145 sqm (1,560 sq ft) house, you are expected to pay a base price of 50.07 and a consumption price of 44.82, totaling 94.89 €/month. On top of that, there is an additional 19.22 charge for metering services.
That means about 114 €/month for just warm air.
If I check prices on Check24 for the same 5 megawatt-hours, I arrive at 303.16 €/year plus roughly 100 for maintenance and another 100 for chimney services, which comes to about 42 €/month, a huge difference in my view.
Even if you factor in a gas boiler that needs replacement every 20 years and costs around 3,000 €, that adds only about 12.50 € per month.
The “free electricity” generated by the community is then sold at quite a high price. However, it seems you can choose a different supplier here.
Have I missed anything, or are the ongoing costs really that much higher per year with this supposedly super-efficient power plant? It makes you wonder whether it might be better to take out an additional 50 € loan and try to buy something else, or if the running costs simply make the price unattractive again.

The prices for heat from a combined heat and power (CHP) plant are not exaggerated—actually quite reasonable compared to a district heating network. With district heating, you naturally have a significant investment share in the network infrastructure, which should be much lower in a project like this.
The factor that might be crucial for the provider: with a CHP plant, you can achieve a primary energy factor of 0.3–0.5, or possibly even 0.0 if it’s a larger unit with a corresponding electrical efficiency. Additionally, this meets the renewable share required by the Renewable Energies Heat Act. This way, the provider can reach KfW 55 standard or better without much additional technology, or at least comply with all legal requirements without solar thermal systems or similar. Would that be an option for you if you only consider the supply and possibly the lowest purchase price? I’m still quite uncertain and basically don’t want to lose what I saved on the house through ongoing costs.

If, based on my simple calculation with the basic data I have, I still have to pay a higher amount for a five-stage system over the lifetime compared to the gas boiler I would recommend double-checking your basic data—the gas boiler does not have the efficiency of a combined heat and power unit; with only 5 MWh, the house will stay cold. You should calculate with at least double that amount, as it is unlikely you will get by with less using a gas boiler. You’re also overlooking the annual costs for the chimney sweep and inspections, which you will have to have done at least during the warranty period. Whether it ends up being somewhat more expensive or cheaper is hard to predict. In any case, the difference is not significant.

It’s safer to calculate at least double that amount; with less, a gas boiler will hardly cover the needs. You’re also forgetting the annual costs for the chimney sweep and inspections, which you'll have to have done at least during the warranty period. Whether it ends up somewhat more expensive or cheaper is anyone’s guess. In any case, the difference is not significant. However, the fees for the chimney sweep and inspections are already quite reasonable.

hampshire6 Jun 2020 19:52Yes, the 200 per year is included. I overlooked that. Generally, combined heat and power (CHP) units base their recalculations on the local standard basic rates and stay slightly below them. If you order fuel and optimize every year, you can operate your own system more economically as long as nothing unforeseen happens. You can make the costs look favorable or expensive, however you want.
For tasks I don’t like doing, I calculate my daily rate. If I can buy something cheaper, I prefer to work an extra day because I mostly enjoy that. Managing contracts is not one of those tasks. That’s also a form of making costs look better than they are.
