Which heat quantity meter do we need and approximately how much will it cost?

Our single-family house has a heat pump of the brand Viessmann, model Vitocal 222-G. It is a brine-water heat pump with 9.6 kW output and 250 L storage capacity. To receive the government subsidy, we now need a heat meter. Does anyone here have experience and can tell me which type of heat meter we need to get and approximately how much the device will cost? Thank you very much!

A heat meter costs about €300; I cannot recommend any manufacturer or type, it is best to have your installer offer you a device. Check the technical description, perhaps a heat meter is already built into the device.

Hello

For the sizing of the heat meter, you need the nominal flow rate, min-max flow rate. This way you can determine the heat meter.
Price starts from about 350 CHF (Siemens meter)

Best regards

Hello,

We have also purchased a heat meter and we have one from the company Zenner. It cost 280 CHF and we bought it here in Switzerland.
