Hello,

Today I found out that two electricity meters are planned to be installed in our new single-family house:

One for general household electricity and
one for heating electricity for the heat pump.

Our electrician wants to install the latter because he believes that heating electricity is cheaper than electricity for other consumption.

Unfortunately, there is no cheaper heating electricity available in our town, and I want to keep my existing electricity contract with EON, which I signed at Media Markt with a rate of 30 cents/kWh, and use it in the new house to bill both household and heating electricity.

According to EON, I can only bill one meter with this contract.

Within the next five years, a photovoltaic system is planned to be installed. At that time, I will definitely need a second meter.

Therefore, my question is:
Is it better to have only one meter installed now to cover current needs?
Or should the second meter be installed right away for the future photovoltaic system, even if it remains unused for the first few years?
For such an unused second meter, is there only an annual meter rental fee of about 20 euros, or am I required to have a separate electricity contract for that meter with a corresponding fixed monthly fee?

Unfortunately, I received many different answers to these questions today.

What makes you think you need a second meter for a photovoltaic system?

We have a photovoltaic system and a heat pump, and everything runs through a single meter.

This information was somewhere between the lines in the flood of details today. Unfortunately, I can't recall the context right now...

You only need a bidirectional meter for the photovoltaic system.
The electrician usually installs a simple DIN rail meter in front of the heat pump to measure its consumption separately.

Most heat pumps already have an integrated electricity meter, don’t they?

Often only heat meters are used, from whose data the electricity consumption is then "calculated," making it quite inaccurate.
