ᐅ Alternative to Gas Heating: Photovoltaic System / Pellet Heating?

BauherrHello!
I currently have a gas heating system. Due to the continuously rising gas prices, I would like to switch to something else. What sensible alternatives can you suggest?
How cost-effective are photovoltaic systems or pellet heating systems?
Thank you very much!

Even though you had to wait a long time for a response and apparently no one had an opinion on this, you will get feedback from us.
Regarding the photovoltaic system, you probably mean a solar system for water heating, which means you use the sun to warm your domestic hot water. A photovoltaic system only generates electricity but, if sufficient surface area is available, it might also be interesting for you; however, that is a different topic.
There are several strategies to reduce your heating costs. The first step is to fundamentally reduce your consumption. You can achieve this by improving energy efficiency. Options include replacing windows, insulating the facade, and much more. Using new heating technology is also possible. If your gas heater is already quite old, maybe 10 to 15 years old, a straightforward replacement might be worth considering. Modern gas condensing boilers from well-known manufacturers typically cost around 5,000 € (about $5,500). Depending on the age of the system being replaced, savings of 20 to 25% are possible. I find Wolf reasonably priced.
Depending on your budget, solar support (not photovoltaic!) could be considered. A pure hot water support system is available for around 3,000 € (about $3,300).
Pellet heating is more complex. Do you have space to store pellets? If not indoors, an outdoor pellet tank is an alternative but more involved. Overall, you should expect an investment at least in the five-digit range. There are subsidies available for pure boiler replacement, solar support, and pellet heating. However, since many people are currently applying for these funds, it is possible that the budget runs out by the time you decide. So, don’t rely on this funding too firmly. From an investment perspective, gas heating is definitely the most affordable option; even with solar support, the system will likely be several thousand euros cheaper than a pellet heating system.
Also, have a look at Initiative Erdgas pro Umwelt. There you will find some information about photovoltaic systems and gas condensing technology.
