ᐅ Heating: How useful is water analysis?

Hello everyone

I have a 23-year-old heating system (unfortunately a 20 kW electric heater = now with very high energy costs 😡 ), and the heating system (underfloor heating) is being flushed again after 4-5 years.

The heating company recommended doing a water analysis beforehand (around 600.--).

Does such an analysis make sense?
If yes, what is it for and how often should it be repeated? (During the last flushing 4-5 years ago, an analysis was done and all values were within the "green" range.)

I am also considering replacing the heating system (old: electric) with, for example, an air-source heat pump.

Thanks for your information.

25 Years of Underfloor Heating

Hello

25 years is enough. Why not change everything right away?
My idea: install an oil heating system and use heating strips along the exterior walls. This creates radiant heating, which is the healthiest for people. It can also be installed by yourself.
I plan to do the same in my house within the next 5 years.

Kind regards from Dämmunsinn

My idea: install an oil heating system, with baseboard heaters on the exterior walls. That provides radiant heat, which is healthiest for people. And it can also be installed by yourself.

Hello Dämmunsinn

No, no; an oil heating system is not a solution or alternative for me.
Because I:
1. Don’t have space for an oil tank
2. Oil prices will inevitably rise significantly sooner or later (oil is currently much too cheap)
3. From an ecological perspective, it doesn’t make sense to use a non-renewable energy source (this is my personal opinion)

That’s why I want to understand what makes sense or not with regard to water analysis.

And if the entire underfloor heating system ever fails (for example, leaks everywhere, etc.), you can still install radiant heaters or raise the floor by 5–10cm (2–4 inches) and lay a new underfloor heating system (the room height would allow that).

Hello Fujiutsu

1. I am not familiar with water analysis; what is it useful for?
2. Oil is still the cheapest energy source. To this day, no one really knows where it comes from. When people say there will be no oil left in 40 years, it’s just scaremongering. People always react quickly to that kind of talk. (see swine flu, which became a huge business for some)
3. Wood chip or pellet heating systems will never be installed in my house. Because wood chips and pellets have a large surface area, they absorb moisture from the air and develop mold.

Hello Fujitsu,

Typically, a underfloor heating system needs to be flushed every 10 years at most, depending on the pipe material (plastic, copper, composite pipe, etc.). If you had good results and little sludge in the pipes during the last flushing, you can wait a bit longer before the next one.

A water analysis is also useful and serves as a basis for deciding when to perform the next flushing.
