ᐅ Hydronic Wood-Burning Stove, Underfloor Heating, Heat Pump, Photovoltaic System in New Construction?

I wanted to ask something here, even though it doesn’t completely fit the topic.

I am building a KfW55 house with 120m² (1,292 sq ft) in April, equipped with an air-to-water heat pump and a central ventilation system with heat recovery. Currently, I am wondering whether I should also install a fireplace or not.

Is it sensible to add a stove in case it gets colder in winter, so the heat pump doesn’t have to work as hard?

Or can you safely do without it?

Because installing a fireplace does involve additional costs, like the chimney and air pressure monitor, etc.

From an economical perspective regarding heating, definitely not.

@GManuel: We are also building next year, our house will be 160 m² (1,722 sq ft), and we will most likely go for an air-to-water heat pump (99% sure) along with a mechanical ventilation system with heat recovery. We also spent a long time considering whether to install a wood stove. Partly because many people claim that air-to-water heat pumps aren’t efficient enough, and I was worried the house might not be warm enough in winter. Plus, all the other builders in our area are installing stoves, so we thought there must be a good reason for that. However, neither of us is really a fan of stoves. Sure, the warmth is nice, but honestly, we currently have a stove in our apartment (sometimes used as the only heating source to keep oil heating costs down in our 1970s building), and we dislike the mess and effort involved. We seriously considered if we would realistically use a stove regularly and if it would be worth the money, as it’s not cheap… We came to the conclusion that while it might be nice occasionally in winter, neither of us would want the hassle and dirt on a daily basis, including carrying and storing wood and such. It would probably end up being lit once a year at Christmas just for the atmosphere and otherwise not used, to put it bluntly. So we decided against a stove; it was too expensive, and with our floor plan, we wouldn’t have had a good spot for it anyway. We’d rather invest that money in things that are more important to us. I hope we won’t regret that decision later, but on the other hand, I’m sure there are people who have a stove and don’t use it, then regret spending so much on it.

Compared to a stove, however, an air-to-water heat pump should be significantly more efficient.
In my opinion, there is really only one sensible reason to choose a stove: coziness.

A stove involves costs, including the initial purchase, loss of living space, and operating expenses... plus the mess it creates.

In my opinion, these factors are not proportional... we have consciously decided against having a stove and have not regretted it so far...

If the air-to-water heat pump is not sufficient in winter, you will simply heat with electricity, which is not more expensive than installing a stove.
