Hello everyone,
Our building contract includes gas with hot water heating and underfloor heating.
For an additional 12,000€ (approximately 13,000 USD) we would get an air-to-water heat pump. From our perspective, that’s too expensive, right?
The idea was to have gas installed first, then sell the gas boiler later and install the heat pump afterward (by outsourcing the work separately).
Is it that simple to swap, or is our idea missing something?

The gas boiler operates almost maintenance-free for about 15 years,How does this statement align with the Energy Saving Ordinance and the TRGI?
Energy Saving Ordinance §11
(3) Heating, cooling, ventilation, and domestic hot water systems must be operated properly by the user. Components that significantly affect the efficiency of such systems must be regularly maintained and serviced by the operator. Maintenance and servicing require expertise. A qualified person is one who possesses the necessary knowledge and skills for maintenance and servicing.TRGI
The TRGI clearly specifies an interval of 1 year or according to the manufacturer’s instructions for gas appliances.
The manufacturer also requires compliance with warranty conditions, usually service once a year or every 2 years.
By the way, heat pumps are also practically maintenance-free. However, you definitely do not need a chimney sweep for them.

Who knows if burners will still be allowed indefinitely, since the energy saving regulations already penalize this system. The planned end date is 2030.
Therefore, all necessary measures should be taken to switch to a different heat generator.

If you have a general contractor who wants to charge more than €10,000 (about $11,000) extra just for having a heat pump, then you basically have no choice.This very important question should be clarified before signing the contract. If in doubt, you simply choose another general contractor.
We have also decided on an air-to-water heat pump... without an outdoor unit. It is a combined air-to-water heat pump with controlled residential ventilation including heat recovery (KFW 55 house).
I would have preferred a ground-to-water heat pump, but that was no longer feasible. We have already made preparations for a future solar upgrade to partially generate electricity for the air-to-water heat pump ourselves and thus reduce costs.
Whether our air-to-water heat pump was a good decision, we will probably only know in a year... On Monday, the screed will be installed, and a few days later the heating system will be put into operation. Let’s see....

Some of you are really spreading panic here. If gas heating is actually banned by 2030—as the FDP is advocating—no one will force me to replace an existing gas system with who-knows-what.
Those who have gas heating will be allowed to keep it... the same goes for oil. This is a matter of legal certainty. A previously legal situation cannot suddenly become illegal. Protection of existing rights.
The energy-saving regulations and all that fuss can leave me alone... a heating system is working, and as long as it works, no one needs to tinker with it. If it acts up, I call the technician. Our old gas boiler only needed him twice between 1997 and 2016: once to replace the three-way valve, and once for something I’ve forgotten. One time it cost 600 Deutsche Marks, the other about 200 Euros. That was it. It’s still running today.
Our installer doesn’t trust heat pumps because of the compressors. Karsten
