ᐅ Utility Costs Settlement – How Should the Statement Be Prepared?

Hello

We have a single-family house with a granny flat. There is a central heating system (Viessmann air heat pump) and a hot water buffer tank.

A heat meter is installed at each underfloor heating manifold.

Additionally, there is a hot water meter in the granny flat.

I have tried to research online how to prepare an operating costs statement, but without success.

I would be very grateful for any tips or explanations.

Calculate the total. Heating electricity. Maintenance costs. Determine the heat meter readings. Both apartments together make up one hundred percent. Now allocate the identified costs according to the reading values.

I hope the distribution of costs is specified in the rental agreement – even if your question doesn’t seem to suggest that.

Should the electricity consumption be allocated based on the heat meter readings?

How do I do this for hot water?

Why? The heating costs are already included in the heating bills, meaning electricity. For water in general, there are water meters.

Hello,
I would recommend having the billing prepared for the first few years. Once you understand it, you can handle it yourself in the following years. If a completely unrelated tenant is living in the apartment and the billing is incorrect, it can become expensive if the tenant disputes it.
I also hope that not only the tenant but you as well have a water meter for the hot water. That way, it works like with heating. The electricity consumption is either divided proportionally or possibly based on data from the heat pump between heating and hot water. Then, from all costs—fixed and variable—you calculate the price per unit, and both you and the tenant pay according to your consumption.
