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)

Not in my case. Please read carefully 😎
I spoke with the specialist earlier. He showed me the installation plan. 26 heating circuits 😎 By the way, the company is ATHE-Therm.
Is that too many now? I thought the more, the better? Now it’s too many 🙂You already have interior plaster, so are your heating circuit manifolds surface-mounted?ypg schrieb:
Just to be clear: my house has been standing for 9 years, and I have been managing my underfloor heating loops quite well 😉 ! However, the statement from @Mahri23 seemed a bit questionable to me, so I wanted to ask for clarification!If the refrigerator is placed on a heated surface, theoretically it has to work against that.Theoretically.
First, the refrigerator stands on legs about 5cm (2 inches) high and is ventilated underneath for its cooling fins.
Second, we have KfW new-build standards, so the 0.5–2°C (0.9–3.6°F) at the floor level more or less don’t matter. (The screed is a relatively good thermal conductor.)
That said, if you can plan for it, there is no reason not to optimize it right away.
I calculated the cost of my expensive KfW 40 XPS insulation under the floor slab plus foam glass perimeter insulation to avoid thermal bridges in the base area.
It cost me about 3,500 euros for a 150m2 (1,615 sq ft) floor slab.
It will never pay off within 100 years. It was purely for subsidy reasons.

You already have interior plaster, so are your heating circuit distributors surface-mounted?!The heating circuit distributors are “hidden” in the wall. There are two boxes. Both are located in the hallway. One is in the wall towards the dressing room, and one in the wall towards the pantry. Here is a photo and the floor plan.

@Neubau2022 which screed are you getting? Cement or anhydrite?
Anhydrite, meaning liquid screed, has better thermal conductivity but also different disadvantages.Here is the description of the screed. It is anhydrite.

Neubau20223 May 2022 07:23Good morning everyone 🙂
I received the plan this morning (see attachment).
Converting the PDF to JPEG unfortunately reduces the quality significantly.
Here are the relevant details:
If I’m reading it correctly, there are 1x 13 and 1x 14 heating circuits, so a total of 27.
The maximum circuit length is 80m (262 feet).
The supply temperature according to the plan is 35 degrees Celsius (95°F). I personally find this quite high. I will ask about it again. Isn’t the setting done by the heating system installer and not by the underfloor heating company?
In the living room, kitchen, children’s room, and main bathroom, the pipe spacing is 6.5cm (2.5 inches).
In the bathrooms, bedrooms, office, utility room, and corridor, the pipe spacing is 13cm (5 inches).

No, everything fits, you will never reach 35°. That number is just irrelevant. Okay. So everything is very good, or at least well planned, and I can just sit back and drink cheap whiskey with cola? 😎
