Geothermal energy or gas condensing boiler?

Hello,

I would give you the following tip.

There is no more efficient heating system than a gas condensing boiler. No other heating system comes close to these efficiency levels. A heat pump neither. Heat pumps have the crucial disadvantage that they are powered by electricity. An annual performance factor of, for example, 3.5 means that the heat pump delivers 3.5 times as much heating heat as the electrical energy it consumes. Such a seemingly positive balance is relativized when the heat pump is powered by electricity. Only about 1/3 of the primary energy used in electricity generation (e.g. lignite) reaches the end consumer. With a performance factor between 3 and 4, this is a zero-sum game. To perform better ecologically than a gas condensing boiler, the performance factor would have to be >4, a value that is usually not achieved in practice.

In this context, it should be noted that with a heat pump you have to be tied to the local grid operator. Unlike natural gas, for example, you cannot switch suppliers. If the grid operator raises prices, you cannot choose a different supplier.

At present, it is advisable to install an efficient heating system combined with a thermal solar system. A heat pump does not count among these.

In this context, it should be noted that with a heat pump you have to be tied to the local network operator. Unlike, for example, natural gas, you cannot change the supplier. If the network operator raises its prices, you cannot choose another supplier.

That is not correct in that form.

In this context, one should note that with a heat pump, you are bound to the local network operator. Unlike with natural gas, for example, you cannot change the supplier. If the network operator raises its prices, you cannot choose another supplier.

However, I consider this to be a myth. In September last year, we switched our heat pump electricity from RWE/Westnetz to E-Wie einfach. This September, we switched to Maingau-Energie.

For heat pump electricity, I think there are fewer providers than for regular electricity. On comparison portals, you have to search (I found nothing for heat pump electricity on Check24). But a change of provider is possible at any time (apart from the general contractual obligation, which as far as I know also exists with gas suppliers).

Good evening,

Heat pumps have the decisive disadvantage that they are operated with electricity.

And a gas condensing boiler runs without electricity?

At the moment, it is advisable to install an efficient heating system combined with a thermal solar system. A heat pump is not included in this.

In view of the upcoming tightening of the Energy Saving Ordinance, it is probably rather the case that a gas condensing boiler will no longer be classified as "cheap" by builders. I am curious how you will market that

Rhenish greetings from on the road

Hello,
With a coefficient of performance between 3 and 4, it is a zero-sum game. To perform better ecologically than a gas condensing boiler, the coefficient of performance would have to be >4, a value that is usually not achieved in practice.

This applies to air-water heat pumps, brine (and comparable wwwp like well or also direct evaporators) easily achieve 4. So far, I have reached 5 with brine (and hot water).
