House construction 2016 + gas heating

That is of course annoying. Although I don’t consider that universally valid. For many other builders (and also for us), a gas condensing boiler with controlled residential ventilation worked perfectly.

True. I keep wondering about that too..

I built the house exactly as stated in the assembly instructions. And it works much better than calculated. Even though I followed the 80% method during construction: 80% is enough, the other 20% only costs money, time & energy.... haha.

The energy consultant (who I needed here in NRW) comes to the same conclusion with the house – it’s close to KFW55.

I suspect the manufacturer company calculated way too conservatively, which made it seem like you need a catastrophic investment.....
I guess it’s owed to the principle of building a house and tolerances.... I suppose.

The ST would – I learned some basic math professionally and have forgotten very little – absolutely not necessary in reality.

Now I won’t get any more upset. 4.5 sqm (almost 5) of valuable (haha) roof tiles are super protected against weather influences. The thing is just there. You can look at the numbers..... try to be happy somehow..... and talk yourself into the pointless.
Since I have the photovoltaic system, I have become the eco guru in the Gäu here anyway; everyone rings the doorbell wanting coffee and some knowledge.... (two now have a photovoltaic system .... they were smart and had delicious coffee, the others declined the investment in ST, they wanted to retrofit and are now spending the money on the garden and such).

The – completely unimportant and pointless – increase in my popularity and Jesus sandal-eco status in the neighborhood by arming this tiny hut with collectors on the roof until the boards crack...... well, I honestly have to chuckle hard right now....

Best regards

I have to work against that.

My new car (coming in July, hopefully) - I'll just stick on a

AMG63 - V8 badge on the back for fun. I bought the very small engine without type designation..... hardly anyone notices. Because I ordered the exhaust trim on both sides for little money. Spirit stove with a flashy image. And space - for the AMG badge....;):)

Also Abi 85 - Dad pays, gas costs 3.10 euros too.......

Very useful here: The construction cost increases make the carport unnecessary. Everyone passing by here sees the car....

So soon I'll be an environmental sinner again.....Smile.

:D:eek:

So I have a kind of dummy system on the roof and I can't escape the hot water in the summer...however, that doesn't mean that I like it and that the investment was worth it.

I completely agree...it's really not worth it here, even though I sometimes have solar gains in winter...but I still wouldn't recommend vacuum collectors, unfortunately, they break even faster than the flat ones.

P.S. I bought a 2.2 diesel SUV last year, am I out now?

The share of renewable energy caused this strangely expensive useless system. Yes.
Otherwise, based on the values, the house easily and comfortably manages everything with one hand, it really wouldn’t need this ST system at all. Even mathematically, the controlled residential ventilation/heat recovery brings significantly more, which is credible in practice. The ST values – fabricated, nicely calculated, pure idiocy.

It could have been avoided. With a heat pump.

A neighbor of my property will start building in September. At first, he wanted a ground-source heat pump, but due to the high costs, he decided against it. Now he is building with a gas heating system. He probably has to install an air-water heat pump as well, but it will probably never be properly operated.

What does he have them for then? That's nonsense.

I would like to see the calculation. That one geothermal heat pump with a subsidy of 4,000€ is more expensive than an air-to-water heat pump + gas condensing boiler + connection. You also need a larger utility room for that.
