ᐅ Heat pump on a separate meter or combined with household electricity

Hello

We are now considering whether to run the heat pump on a separate heat pump meter or to connect it normally to the household electricity supply.

What additional costs should we expect if we use a separate meter? The electricity costs are clear, but are there other fees, such as installation costs, that may apply?

Hello

We are now facing the question of whether to connect the heat pump to a separate heat pump meter or to run the pump through the regular household electricity supply.

What additional costs come with having a separate meter? Electricity costs are clear, but are there other charges? For example, for installation, etc.?

Hello, this is not really a question. The heat pump is automatically connected to a separate peak/off-peak meter. So you pay double standing charges. The advantage is that the electricity for the pump is cheaper; the disadvantage is the standing charges and the general electricity cut-off. For us, this is three hours around midday. Sometimes, water for showering is cold at midday.

Oh, so basically you don’t have any choice at first?

I have often heard that some people run the heat pump on household electricity, since the costs are not significantly higher.

It’s a question because it doesn’t have to be automatic. You can connect everything to a single meter and, for example, have a submeter installed to measure the electricity consumption of the heating system yourself.
I personally have two meters, but due to the low electricity demand of my heat pump for heating, the savings from avoiding additional basic fees are small (double digits). So it’s not necessarily worth it. Interestingly, our provider has never actually enforced a disconnection period.

We also considered it. We don’t need to use two meters, at most a disconnect device; my electrician is currently looking into that. However, we are also opting against the second meter because the estimated savings of €4 per month do not justify the extra effort for the initial installation, and afterwards, you are tied to providers that offer a suitable tariff.

But we have planned space for the second meter to remain flexible.

We only have one meter with a submeter (for entertainment purposes). We pay 0.248 cents/kWh (regardless of whether it’s for the heat pump or household electricity) and have no basic fee at all.

In hindsight, I would have even skipped the submeter, since the heat pump already has one built in.
