ᐅ Liquefied Petroleum Gas (LPG) to Natural Gas Conversion or Direct Heat Pump Installation? Experiences

Hello everyone,

I have a challenge for which I would really appreciate your opinions or feedback.

Current situation:

• There is an existing house, 2.5 stories, approximately 150m² (1,615 sq ft) of living space.
• Currently running on liquid propane gas, with a tank located in the garden. The new heating system (Viessmann) is about 2 years old.

Planned work (financing is secured):

• Temporary relocation of the gas tank on the property (because an extension will be built exactly there)
• Construction of the extension (heat pump), starting in the coming weeks
• In about 6 months, natural gas will be available locally, then switch to natural gas and removal of the propane tank
• A photovoltaic system covering around 40m² (430 sq ft) of flat roof is planned.

However, given the current situation, it is now very questionable whether switching to natural gas (as planned a year ago) makes sense.

An alternative could be:

• Relocate the propane tank on the property
• New construction as planned
• Convert the existing house to a heat pump as soon as possible
• Remove the propane tank
• Cancel the natural gas connection

This option would incur additional costs of around 20,000 euros.

From your perspective, is this now reasonable (considering the heating system is only about 2 years old), or would you continue using natural gas for a while longer? (We don’t really want to; my main concern here is the financial aspect — I am aware that natural gas is not ideal politically or ecologically.)

Thank you very much for your input!

Best regards,
Rüdiger
