ᐅ Costs for heat pump, water, and electricity

Hello everyone,

I hope this topic is posted in the right section or generally appropriate for this forum. I am a new property manager and have a problem with the billing of electricity, water, and heating electricity. I have attached an image listing all the values. The building consists of 4 residential units (Unit 1 to Unit 4).

Can someone explain how to calculate the costs for each individual unit? Calculating the total water consumption cost is not an issue, but for example, electricity is needed to heat the water. However, there is no specific price per cubic meter for hot water. How should I calculate the electricity costs for heating the hot water for each unit?

Additionally, there is a general electricity meter connected to the heat pump, which supplies, for example, the corridor lighting or the bicycle storage room lighting.

How does this work for the electricity consumption of the electric auxiliary heater and compressor? This consumption is not reflected on the general electricity meter, which I would have expected. I am a bit confused here and might be missing something. Hopefully, someone can help me.

Thank you very much and best regards

To be honest, I doubt that the meter generally includes the heating electricity for the heat pump. From my perspective, it could be the system power (circulation pump, etc.) of the heat pump and, as you mentioned, the hallway lighting. Otherwise, the numbers simply don’t add up.

Is there no main electricity meter that basically measures the entire house connection? At least that’s what I would expect, and that’s what I assumed in my instructions. I would only use the total heat quantities to allocate the electricity costs—so proportional heat quantity divided by total heat quantity, multiplied by total electricity costs.

That’s what I meant by apportioning.

So, how is this arranged? Do the residents have individual electricity contracts, or did you receive a single electricity bill?

Maybe I didn’t explain myself clearly. To break it down a bit further: there is no overall electricity bill. There are a total of five electricity meters. Each residential unit has its own meter, and the electricity is billed separately by each unit, meaning every unit has its own electricity provider. The fifth meter is the “common” one. It covers everything like the hallway lighting but is also supposed to be connected to the heat pump and has a separate electricity provider contract as well. I assume that this meter additionally measures the electricity that is required for the operation of the heat pump itself (i.e., electric auxiliary heater and compressor?).

Oh, I see. Okay, that’s under General Hot Water. What kind of meter is that? Where is it located?

And what consumption is currently listed on the bill from the main meter?

I have had good experiences with the online tools at eddi24 for creating heating and additional cost statements for tenants. The pricing is quite reasonable, which tenants also appreciate. Once set up, the following year you can directly use the values already saved. The tenants receive a clean statement as a PDF printout, including a small statistical comparison to their previous year's consumption and to the overall consumption of the building.

The best software is useless if it is unclear what the meters are showing or if they are installed incorrectly.
It is obviously problematic when the heat pump and general electricity are connected to the same meter.

The hot water meter listed under General is a heat meter installed on a pipe next to the heat pump. The meter is labeled “hot water” with a marker. There is no bill available yet.
