Program heating settings for nighttime

So the price is really steep. It used to work before, right? So as I said, I would then buy the old controller and reinstall it. Even if it is used, etc.

It is then an outdoor temperature-controlled low-temperature boiler. It probably was that way before as well. Constant temperature means: no matter what, I go to 60 degrees flow temperature. Always. Weather-independent. Please use Google.

I have consulted Google, but I am still not really any wiser.

What we know:

On the boiler itself, terms like constant temperature, low temperature, condensing boiler or whatever cannot be found.

The chimney sweep said we don’t have to replace it (which still doesn’t take into account that a heating system might break down due to old age and then a repair is no longer worthwhile).

Among other things, I read during my Google research:

"A constant temperature boiler for oil or gas can be recognized, for example, by the fact that its temperature remains permanently high during operation. It also has neither an outdoor temperature sensor nor an adjustment option for night setback."

I don’t know how a permanently high temperature during operation is defined. If an outdoor temperature sensor means such a "probe," then we have one on the north side of the house in the entrance area by the front door. And even if we can’t set anything new because the control system is currently defective, obviously something was set here at some point. Because there definitely seems to be a night setback, otherwise the heating would not stay off at outdoor temperature X at 4 a.m.?

Or do I have a flaw in my reasoning?

Can you tell me which heating parts tend to give out due to old age so that a repair is economically unreasonable?

The burner was just replaced, we had the tanks cleaned. According to the chimney sweep (and some maintenance values?), the boiler is absolutely fine at the moment.

Dear

There are so many ready to share knowledge with you. Maybe you should take photos of the heating and everything? Maybe the guys can then be even more precise?

I think 100 euros is not a lot if there is a chance to minimize the problem. Of course, you don’t need a warm temperature from 4:30 onwards, but it is what it is: the tenant needs it. Whether in the ground floor or basement. So 100€ rent goes into this device, with or without warranty. Maybe the unverifiable set night reduction is also way too low? Give it a try :)

I'm currently on the ground floor and can't leave here – I'll try to take a good photo in the basement later and maybe get it to a size that can be posted here? Is there some trick to taking a picture with the iPhone and getting it directly in here? It always tells me the photo is "too large."

Well, I'll put it this way: like probably all new owners, we've already spent significantly more on/in the house in the first few months than planned. And living here, you quickly notice what you'd like more of, or different, etc. But we don't have a money tree here either. According to my husband, there’s no device for 100 euros, more like 200-300 euros, and if that gives up the ghost after 3 weeks because it's an electrical device from the '90s, then that's just bad luck.

Since we can't control the main house and the granny flat separately, we'd have to invest additionally in various wireless thermostats so that the heating doesn't come on everywhere at 4 a.m. 4:30 a.m. is not enough either because she wants it warm long before that, and preferably in summer as well. After all, it’s probably not "warm" in the basement even in summer if you’re freezing at 21 degrees. There are still several things to clarify with her since the heating behavior she wants can't be managed with a flat rate as agreed, and as landlords, as far as we are thinking, we are not willing to bear the costs for such an investment that we don’t need alone.

Yesterday, during an Easter celebration, we talked to someone who knows a bit about these heating things, and somehow everyone tells us we’re completely crazy to pour so much money into a 23-year-old oil heating system again.

We still know too little about questions like gas boilers or other things, but buying a new regular system and equipping the whole house with wireless units will cost us around 2000 euros, and if from 10,000 euros you can already talk about a new gas system, that’s insanely expensive for us—

If I lived with you and was freezing, then you would either have tenant protection or a lawyer on your case plus a rent reduction.
