ᐅ New Construction Heating Technology: Pellet Stove and Tiled Stove

Guan-diHello everyone,
I am currently planning the construction of my new house (the old house will be demolished in August).
I work for six months each year on weekends in a forested area. As a result of thinning the forest, I receive about 20-40 cubic meters of wood annually, which should more than cover my needs.
For ecological reasons, I plan to avoid using fossil energy sources completely in my new house.
Now about my project:
The house will have approximately 160m² (1722 sq ft) of living space plus a large open-air space.
The open-air space will be located in the living room, along with the planned tiled stove.
The entire house will be equipped with underfloor heating and energy recovery through mechanical ventilation with heat recovery.
In the basement, a small pellet heating system will serve as the central heating. The building’s energy demand is expected not to exceed 50-60 kWh per square meter annually.
Since the pellet heating system is connected to a 1000-liter (264 gallons) stratified buffer tank, I am considering connecting the tiled stove to this system as well.
This means the tiled stove’s excess heat will be distributed via the mechanical ventilation system. Additionally, the water heat exchanger will supply energy to the buffer tank and the underfloor heating.
During summer, the buffer tank water will be heated exclusively by solar thermal and pellet heating.
Most of the electricity will be generated by photovoltaic panels.
What do you think of this concept, and do you see any concerns (including economic considerations)?
Do you have any additional ideas or tips?
Which stove inserts have you had experience with?
Is there anything I might have overlooked?
Thank you very much for your help.
Best regards,
Guan-di

Why both a tiled stove AND a pellet boiler?
One of them should be sufficient. The tiled stove will cover the entire heating demand in winter, and if it has a water jacket, it will also charge the storage tank. So what exactly is the purpose of the pellet boiler?
Better to use just one heat generator, preferably wood, since you have cheap access to it. Although there is no subsidy for a wood stove with a water jacket, the low cost of wood balances that out.
And a pellet heating system for domestic hot water in summer? Solar energy is completely sufficient for that. However, I would prefer a domestic hot water heat pump instead of solar, as it cools the house in summer and uses electricity from the photovoltaic system. This also leaves more space for the photovoltaic panels. By the way, solar panels are more appropriately placed on the facade anyway.

Hi, thanks for your opinion.
The problem is that the house is empty several times a week for at least 24 hours since both my wife and I work 24-hour shifts.
When we come home from work, we don’t feel like first lighting the stove and waiting for the water to warm up.
That’s why we chose the pellet heating system.
Solar energy provides the hot water we need in summer, but during transitional seasons it’s less effective.
I’ll have to look into the domestic hot water heat pump. I don’t have any information about it yet.
Best regards,
Guan

With a 1000L (264-gallon) storage tank, the water in the buffer should still be very hot after 24 hours. To charge the buffer, you don’t necessarily need a pellet boiler; a hydronic stove is sufficient. This can save you around 10,000 euros.
Search online for “temperature loss in buffer tanks.”
The domestic hot water heat pump supplies warm water in summer using photovoltaic energy at almost no cost and in winter it recovers excess heat from the stove’s air (with a properly positioned air intake pipe). Prices start at around 700 euros depending on the tank size, excluding installation.

Hi,
It’s simply about becoming more independent from utility companies and so on.
I have nothing against gas, but I do have an issue with the pricing policy.
Pellets are also getting more expensive, but the idea of not being dependent on gas suppliers is reassuring to me.
Wood will always be available.
