I am renovating my single-family house. An apartment will be created on the first floor and attic that I want to rent out.
Is it sufficient to have a heat meter (underfloor heating) on the first floor and attic, but none on the ground floor?
It seems that one on the ground floor wouldn’t serve a real purpose since gas is also used for hot water.
The apartment also has separate water meters for hot and cold water. In my part, there is no additional meter for hot and cold water, only the main water meter.

S_t_e_p_h_a_n29 May 2020 11:41Ok, thanks, and then the plumber installed a heat meter in both the ground floor and the attic. Couldn’t he have just installed one on the riser going up? Nothing branches off there anymore.
Hello
To my knowledge, that is not correct.
Billing companies usually require a heat meter and a water meter for each residential unit, as well as a heat meter for the domestic hot water system.
Otherwise, even without domestic hot water production, the losses from the heat generator and heat distribution would not be fairly allocated.

S_t_e_p_h_a_n29 May 2020 15:00I would cover the losses myself if none are installed in my case.
The house will have a total of 2 residential units, both with underfloor heating. Will one of them be owner-occupied?
Then, a heat meter is required for both the ground floor unit and the upper floor + attic unit. These are usually installed after the branching of the heating circuits to the individual units and measure the amount of heat transferred between the supply and return lines.
Why is a heat meter needed for the ground floor apartment as well?
-> Because heat meters do not measure absolute values but relative heat quantities. For the annual consumption-based service charge settlement, the heat consumption for each apartment must be recorded separately for all units in the building. Otherwise, a calculation in the usual way will, to my knowledge, not be possible. I also use heat meters for billing in a multi-unit residential building.
A heat meter for domestic hot water preparation is also required in addition to cold and hot water meters. In some cases, this is already integrated into the heating system (e.g., heat pump).
