Hello everyone,
I hope someone can help me here! I am completely lost at the moment. We have bought a house built in 1960 with a basement, ground floor, first floor, and converted attic. The total living area is about 135 sqm (1450 sq ft). We are renovating the entire property, basically everything: water pipes, drains, heating, electrical system, windows, etc.
What we are planning for the heating system:
Ground floor underfloor heating
First floor bedroom 2 radiators, children’s room 1 radiator, bathroom 1 radiator
Attic 2 radiators
I have had about 10 heating companies visit to provide quotes, but I don’t understand it. What I do understand, or what I think a heating system consists of, is this:
There is a "burner" and a hot water tank. The burner heats the hot water tank to a certain temperature during specific times, and this hot water is then available, for example, in the kitchen and bathrooms for showers, etc. When the hot water is used up, it must be reheated by the "burner," which could take some time if several people take showers one after another.
This type of system is available as a "fridge" style (e.g., a unit like the Vaillant ecoCompact) or as separate storage and burner. So far, is this correct? Please excuse my choice of words when referring to the devices.
Now, what I don’t understand:
One heating company said they recommend something different. One device only for the heating and a "boiler." Both would run on gas. The one device (I don’t know exactly what it is) would only supply the heating and could be switched off or turned down, for example, during summer.
The "boiler" (is this correct, or what exactly is this?) would, however, provide hot water continuously on demand for the kitchen and bathrooms, day and night.
From a customer perspective, without understanding the technical background, it sounds quite good because the "heating system" is only heated when it makes sense according to the outside temperature, and I would still have hot water continuously, but only when I need it. So where is the catch?
My questions:
- What exactly is he offering me? What are these two components technically?
- Is this common? Why did only one company out of 10 offer this option?
- What would you recommend – option 1 or option 2?
- They said this option would be significantly cheaper. Why is that?
I hope you can shed some light on this for me.
Best regards,
Yavuz

That now depends on the hot water consumption. What they are suggesting to you is a combination boiler. A gas heater that warms the hot water on demand as it flows through, similar to an electric tankless water heater. This works and is neither new nor particularly expensive. However, if a lot of hot water is used for a long time, it eventually only delivers lukewarm water. So, for two people mainly taking showers, it’s okay. But it’s not ideal for frequent bathtub use.
