Scenario 1: Winter day, 0°C (32°F) with sun around noon.
Living room facing south with glass front, kitchen facing north. How does your heat pump manage without an ERR to prevent the living room from becoming boiling hot or the kitchen from getting too cold?
Maybe the Viessmann Blablubb-Eco-XX with smartphone app control and weather service integration, working together with the smart home central unit and photovoltaic yield measurement based on the battery storage charge level and Alexa presence sensors, can manage it even without an ERR, but a thermostat valve is definitely simpler.
Yes, I know, "self-regulation" of the underfloor heating—but that is at least as slow as the underfloor heating itself and only works moderately well.
But especially during a raclette dinner or cooking with friends, or any other heat input that can't be anticipated based on outdoor temperature, your central control (without regulation based on room temperature) will fail, even with the "self-regulation effect of the underfloor heating." The house won’t burn down, no one will freeze, and there will be no building damage, but it will simply be uncomfortable. And considering how much money is sometimes spent here on fancy tile designs, stair railings, garage doors, or KNX systems, adding an ERR delivers a very high comfort return on investment.All of this has nothing to do with smart homes or apps or weather services or whatever else—sorry to be so blunt—but you clearly have little to no understanding of the subject and either can’t or won’t engage with it. No one spoke about a control system “without” indoor temperature—it’s obvious that any reasonable heating needs an indoor temperature sensor, but just one. And why do you mention a self-regulation effect of the underfloor heating? I never said that. I was talking about the logic of a heat pump working better with a proper hydraulic balancing than with an ERR, where the intentionally warmest room forces the others to be throttled. You then have to run a higher supply temperature to get that one room as warm as you want while lowering all the others… wow, super effective.
How do you know it’s uncomfortable? I’d say it’s more uncomfortable during every transition period or when the sun shines, and the ERR goes up and down but nothing happens because the underfloor heating is too slow… haha.
Sorry, I just don’t like it when someone spouts such barroom talk and unsettles others who are interested in an effective, comfortable heating system (without any electronic gimmicks).
The ERR is not an optional comfort upgrade you can add—it’s a legal requirement under the energy saving regulations—but it’s total nonsense because most people don’t know how to operate a heating system properly.
Oh, and one more thing: if you’re roasting in the living room on a winter day with midday sun, then you probably don’t know anything about proper shading… and then the heating system can’t help either…

It’s either wood or tiles. Exactly. That’s why I find it amusing when people who usually prioritize “organic” materials install ceramic products with a wood appearance. Those people in particular—more so than I—should find such products as “transgenic” rather unappealing.

The background is that compliance with the development plan is strictly monitored by the mayor, without any possibility of deviations. What exactly is the royal Bavarian mayor’s requirement about: is it a specific color tone from a list or a range of shades for the roof or windows, or is it “if gray, then roof and windows must match exactly”?
To achieve an “exact color match” between different materials, you would have to define it according to Pantone; this is impossible with RAL. The “similar” designation related to RAL color codes for building materials is no coincidence. This is less about variation within a production batch or a single lot, and more about how identical color pigments appear differently depending on the surface quality.

Josephine, in our residential area, there are several houses that have been without plaster for years. Is that common practice? What is the plan for your place?
Our plaster was originally scheduled for June but couldn’t be applied because the shell contractor was delayed with sealing. So, we are actually behind schedule.From completion of the shell + roof + windows?
After that came electrical work, floor insulation, screed, plaster on the walls (base plaster and fine plaster). Then a long drying phase.
Afterwards, tilers and painters worked, while technical installations and small finishing tasks were done simultaneously.
Then ceiling moldings and painting, including ceilings and drywall partitions, with tilers working in between.
They finished this week; the carpenter is currently installing the staircase along with the wardrobe and window seat.
Paving stones are ready for the driveway and terrace.
Exterior plaster is planned for October, but we might already be moving in by then.
So far, it all seems quite logical to us...[/QUOTE]
The paving is finished and compacted. What I like is the channel made of stone instead of a grate, and how neatly they paved around the manhole cover – that wasn’t planned, and I hadn’t really thought about it either...
Actually, I thought the path to the front door was too wide, but it’s fine, you can easily park a bicycle there or something. Or maybe a planter will go there, we’ll see.
Hopefully, they will clad the terrace just as neatly.
Still no bathroom photo, but the kitchen will be installed next week.
