Then I would also like to introduce our building project here and keep you updated.

First, a brief introduction about us. He (42.5 years; controller in healthcare), she (38.5 years; full-time teacher), child (8.75 years; fully dependent). Our household net income is currently about €6,400 (approximately $6,800) plus performance bonuses, 13th-month salary, overtime, etc. We own a 1,462 sqm (15,735 sq ft) plot of land in Fichtenwalde. The remaining debt on the land is €37,000 (about $39,000). According to official land value guidelines, the land is valued at €146,200 (about $156,000) (€100 / sqm). The market price is around €400,000 to €600,000 (recent sale prices). We submitted the building permit application including the land conversion at the end of December. We expect approval by mid to late July.

The construction company is KB Brandis from Jüterbog. External site supervision will be handled by Bauherrenhilfe with 13 appointments.

Now about the house. It will be a 144 sqm (1,550 sq ft) bungalow plus a 12 sqm (130 sq ft) covered terrace with the following additions:
- Ceiling height 3.00 m (9.8 ft)
- Electric roller shutters (including smart home integration)
- Double-sided laminated windows (wood-colored; RC3 security rating)
- Brine-to-water heat pump with ground collectors due to water protection area (Bosch Compress 7800i LW)
- Hydraulic balancing of the underfloor heating
- Controlled residential ventilation with heat recovery (Bosch)
- Motion detectors from a security company
- 13 kWp photovoltaic system, including battery preparation
- 10 m³ (2,650 gal) cistern for rainwater use
- Doorbell with video function
- Wallbox preparation for electric vehicle charging
- Exterior lighting

Floor plan attached.

We have not yet finalized financing (although discussions have taken place). So far, we have invested up to €30,000 (approximately $32,000) from our own savings during the planning phase. This is almost all of our equity. However, we continue to save about €2,750 (approximately $2,920) per month. The monthly mortgage payment is expected to be around €1,650 (about $1,750) plus additional costs of approximately €200-250 (about $210-265) (taking into account the photovoltaic system). This means when we move into the house, we will still have savings of at least €1,500 (about $1,590) per month.

The construction contract will be signed within the next few weeks. The prices (recently discussed with the company) correspond to the offer and commitment as of September 2020.

The price per square meter of the house (according to the latest offer and full specification) will be €2,700 (about $2,870). This includes everything, such as painting, flooring, etc. The overall costs are structured as follows:
House: €378,000 (about $402,000)
Land conversion including reclassification: €25,000 (about $26,600)
Additional building costs: €40,000 (about $42,500)
Outdoor facilities: €25,000 (about $26,600)
Total financing volume: €468,000 (about $498,000)

Please explain to us the difference between a chimney and your heat-retaining fireplace.

If you read carefully, you wouldn’t have needed to ask that question. As I already said, it doesn’t make sense to only read what you want to. If you still want an explanation, ask Uncle Google.

Alright. For example, the drywall ceiling hardly absorbs any heat.
Thanks. My masonry heater has 4.5 kW over 8 hours.
That means I put in 10.11 kg (22.3 lbs) of wood once, let it burn for 2–3 hours, and the rest of the heat is gradually released.

Neubau2022 has the same construction method as we did back then, also a drywall ceiling. And a masonry heater is definitely a different concept. I’m not familiar with that.
Neubau2022 has two large glass fronts. If he puts in 3 to 4 logs and lets them burn properly, the heat escapes through these large glass fronts—it’s radiant heat into the room. In this case, potential thermal mass materials used when building or cladding the fireplace are not particularly important.

Neubau2022 has 2 large glass facades. If they place 3 to 4 logs in the stove and burn them properly, heat will escape through these large glass surfaces, since it’s about radiant heat into the room. In this case, potential thermal storage materials used when enclosing or cladding the fireplace are not particularly relevant.

OK. You are right, and I will keep quiet...

I would call it experience.
You always have those 500 degrees (assumed; definitely very hot 😀) on the glass, no matter how you “wrap” the insert with the stones.

...I was proactive in installing the better system.

Just out of curiosity, may I ask what about @Neubau2022’s decision triggered you so much that it led to three pages of discussion?

Other homeowners should avoid making such impractical decisions regarding the fireplace.
Is my brief answer sufficient for you?
