I am wondering if it is possible to heat a bungalow with a pellet stove WITHOUT hydronic (water-based) heating.

Please also take a look at the screenshot.

Basic information:
Heated area: 120 m² (1,292 sq ft)
Pellet stove with about 6 to 7 kW, centrally installed.
Air is drawn in above the stove and blown into the rooms at ceiling height.
The heated rooms have ventilation openings at the bottom of the doors to allow “cold” air to flow freely into the living room.
The stove is intended for heating only and does NOT produce hot water.
The slab foundation will be insulated, no basement.
Flat roof will be insulated with approximately 25–30 cm (10–12 inches) of insulation.
Wooden walls with about 20 cm (8 inches) of insulation between the studs.
Triple glazing. Large windows facing west.
The property is heavily shaded in winter.

Thanks in advance =)

One more request...
I am currently in the stage of idea development and rough feasibility assessment. I am specifically looking for your experiences and subjective evaluations. Tips like “You should ask a professional” are not helpful for me right now.

Before going into such detail: Is the building project even feasible at that location? (my answer from yesterday).

Arguments against pellets: delivery, storage space/storage room, maintenance, and cleaning. The air heating is controlled through floor or ceiling vents. This can lead to a barrack-like climate and possibly to dirt deposits on walls and ceilings. Instead of a pellet heating system, a low-temperature heat pump or building insulation to passive house standard could be considered.

I’m not sure if it’s feasible at this point. Right now, I’m just exploring ideas.

The amount of work a pellet stove requires shouldn’t be underestimated, but I think it offers a sense of simplicity and independence. I’m still undecided whether it’s truly the right choice or if it might become annoying over time.

My main idea was that this house will need very little heating energy overall, as it will be very well insulated, so I can avoid installing a hydronic heating system. (I have had water damage in the past.) This will naturally mean it will be warmer near the stove than in more distant areas. However, that shouldn’t be a drawback, since it’s nice to warm up by a hot stove!

What you are planning is basically a pellet stove with controlled mechanical ventilation. Of course, it works, why not. There is also an Italian manufacturer that builds pellet stoves with warm air outlets, I just can’t recall the name right now...

Yes, I have seen something similar, but from the company MCZ. They call it "Comfort Air" and claim to deliver warm air up to 8 meters (26 feet) away through flexible ducts. Unfortunately, I only know the marketing claims and have no user experiences.

Oops, I just realized that MCZ is Italian, so we were referring to the same company.
