ᐅ Heating System Reliability During Power Outages – What Are the Options?

Dear members,

This is my first post in the forum, and I am looking forward to becoming part of the community.

I work as an IT technician, and if I can offer any advice regarding home networking, home automation, etc., I am happy to share my knowledge and provide help at any time.

Regarding my concern:

I have a ground-source heat pump in my house that heats a cistern. For the particularly cold months, the system is supported by a water-based pellet stove, which is centrally located in the basement and also serves as a heating source. Unfortunately, there is only one chimney in the house connected to the pellet stove, and I would prefer not to have an external chimney added to the outside.

This means I am completely dependent on electricity and cannot heat during a power outage. Therefore, my question:

Does anyone in the forum know of a water-based hybrid stove that can be operated with either firewood or pellets, which I could install in place of the pellet stove in the basement?

So far, my search has been unsuccessful.

Thank you for your responses and efforts.

Best regards from Munich

Markus

In another forum, this topic was also discussed. Backup generators need regular maintenance and must be started periodically to ensure they work when needed. Fuel such as gasoline or diesel must be stored in advance. High-quality backup generators are also quite expensive. Another option is to operate a voltage converter in a car. The conclusion was that all of this requires a lot of effort for the few times that power outages occur.

Another approach was to use a photovoltaic battery storage system. However, this requires the possibility of standalone operation. Normally, the inverter switches off when it no longer detects grid voltage. Above all, you need to have a photovoltaic system and battery storage in the first place.

I can confirm that. Our air source heat pump stopped working. We noticed it because of the cold water (about 24 hours). The house never really cooled down completely.

To me, this sounds like a crazy idea.
I would like to see the cost-benefit analysis.

Okay, good, we have now discussed emergency power generators and so on, but we haven't made much progress because I am still looking for a recommendation for a stove like that (if there is even anything useful available).

@readytorumble - What kind of off-topic reply is that? This could be my problem, right? Did I ask for an evaluation? - No - I asked for a recommendation for such a system.

The problem is that there is no such recommendation. Even if there is a stove suitable for your needs, you will still need a backup generator to actually heat your house. Or do your circulation pumps also run on wood? But without them, it won’t work!

And if you have to generate electricity anyway, you might as well run the entire heating system on it. That way, you only have to deal with one backup system instead of two, as in your solution.

Best regards,
