Costs for the heating & sanitary trade

If you have a good feeling, say yes. A small buffer in the return flow results in only a very slight reduction in efficiency. Unlike a combination buffer or separation buffer. How big should the buffer be? Take the smallest offered if you take one. Only take the wall heater with a heating cartridge, no connection to the heat pump.

40 l is installed in the same housing as the water storage and is also intended by Vaillant. Yes, I still need to discuss the flow temperature and installation plan with him to see if he will adopt the TGA plan or wants to do something else.

Yes, of course if underfloor heating then decoupled with an extra heating cartridge. But the question is whether wall heating or underfloor heating. Wall heating is somehow cleaner, but the wall is still lost. With underfloor heating, at least I can hang the towels. If only the cheap ones weren't so ugly and the "nice" ones weren't so expensive...

So second offer and second conversation are done. I have to say he is moving more and more into my favorite position, which will really be tough for the others. I still have two companies that absolutely want to write an offer and an appointment with a "neighbor". The master is very friendly, flexible, understanding, sometimes overlooks something, but then immediately gives in. So far, apart from the total costs, which are not yet 100% certain regarding the ventilation ("we have to see how it looks on site"), I am very satisfied and optimistic. The payment terms are also good (no advance payment, always 10,000 EUR installments according to progress, 2% discount within 7 days) if the execution works even remotely as well I would be happy. He also does the sub-insulation, for example, but said that this is just busywork and you could easily do it yourself. Regarding the wall heating, my wife has now decided that she would rather have towel radiators (of course only with heating cartridge). Wall heating does steal more space where nothing can then be attached, even if it initially looks cleaner. But she will probably want design radiators that cost 1,000 EUR...

Without wall heating there is more floor space and for €1000 radiators are well invested. Now you get your desired technology/features and not GU standard, it works. I miss cloud images in the new year

Yes, it will be fine. but 1000 EUR per piece doesn't necessarily have to be... So far, nothing else has happened there. The weather is too cold...

But she will probably want designer radiators that cost 1000 EUR...

with the best design, so one with your picture on it........
