Hello,
we have a somewhat complex problem and are currently unsure about what to do. Any experiences would be appreciated.
Our house is 23 years old, with a Buderus boiler and control system; the burner was recently replaced. In our living room, there was a kind of "thermostat" that was already broken when we bought the house. We naïvely accepted the sales advisor’s statement that it wasn’t needed and assumed that the heating could be controlled directly at the unit downstairs.
We suspect that something was set up about 23 years ago, after which no one cared about this thermostat, and eventually, it just broke. The water may be a bit cooler, and our bathroom radiator never really gets warm despite bleeding and unblocking. Otherwise, everything is fine for us. When my husband goes into the living room around 7 a.m., it’s still a bit cool, but absolutely okay, and when I come home in the afternoon, it’s warm in there. So far, so good.
Now, we have rented out our granny flat to a young woman for 8 weeks. There is only one heating circuit. Due to her work, she gets up at 4:30 a.m. This was not a problem before, but since last weekend it seems that the flat is freezing cold when she gets up in the morning. Previously, according to her, this was different, and the heating was running in the morning. Now it isn’t anymore. She feels cold and wants this changed, which I can understand.
Today, a technician was here. The problem is: this control unit is broken. The heating is set to something, the sensor is located outside on the north side, but exactly what was set can no longer be read or changed.
The young woman now wants the heating to be set so that it is warm at 4:30 a.m.
Because we have only one circuit, we cannot separate the systems for the granny flat and the main house. This means we would have to set it so that the radiators start heating at 4:30 a.m. for ourselves as well. This makes no sense for us—no one here gets up before 6:30 a.m., the children get up about an hour later, and we may not be as sensitive to cold.
But to do this at all, a new controller is needed. These parts from 25 years ago are no longer available today—you can get “refurbished” ones from various online shops for around 300 euros, but whether we can still set those ourselves is questionable.
The alternative would be a completely new heating control system, which would cost about 1500 euros; a binding offer will be made. That is certainly even more expensive 🙂
For us personally, everything is basically fine, so this is a lot of money. On the other hand, it may also not be very sensible if you have no way to adjust your own heating, and sooner or later, one might have to invest in this anyway?

Hello, my husband also took another look at the system in the basement, but he doesn’t see any way to adjust anything. We can’t find the buttons that would be necessary; there’s absolutely nothing like that.
We have also received an offer from the technician:
A control unit MC110 RC310 BRM 10 Set retrofit with 7-pin burner connector, storage connection set AS1 with hot water temperature sensor and connection plug, small parts flat rate, installation, Buderus Logamatic BC30 E boiler display for Logamatic MC 110 (display for room mounting set). All together for 1242 euros including VAT.
I understand the technician to mean that we currently have no way to adjust anything on the heating system, whether that’s operation based on time, specific temperature settings, water temperature, etc., and that it’s not ideal to have no control at all over the heating.
What I don’t understand is why we MUST replace the system after 30 years? Is that definite? I haven’t found any information on this, and I understood the chimney sweep to say that, with proper maintenance and a bit of luck, we could still enjoy the heating system for a long time. The heater is now 23 years old, the burner was just replaced, and we would upgrade the controller now—but if we definitely have to replace everything within 7 years, then about 1300 euros seems a bit expensive.

Caspar202027 Mar 2018 14:32The replacement of constant temperature boilers older than 30 years is mandatory. The key factor is the manufacturing year of the heat exchanger. However, some heating systems older than 30 years are allowed to continue operating.
Those who have lived in their own single-family or two-family house since before February 1, 2002, are exempt from the replacement requirement. The same applies to systems in multi-family buildings with a rated output of more than 400 kilowatts, small systems with a rated output of less than 4 kilowatts, as well as to all condensing and low-temperature boilers.
Perhaps you already have a condensing boiler?

Hmm, good question. Should that be stated there?
The house was built in 1995 and has always been used as a private residence by the original owners. We signed the notarized purchase agreement in 2016 and have lived here since 2017, solely for private use.
Are we then exempt?
