Heating: How useful is water analysis?

Hello everyone

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

The heating company has now advised to have a water analysis (approx. 600.-) done beforehand.

Does such an analysis make sense?
If yes, for what purpose and how often is it repeated? (There was an analysis during the last flushing 4-5 years ago and all values were in the "green" range)?

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

Thanks for your info.

25 years of underfloor heating

Hello

25 years is enough. Why not change everything at once?
My idea: install an oil heating system, and use heating strips on the exterior walls. That provides radiant heating, the healthiest for humans. And it can also be installed by yourself.
I will do the same in my house over the next 5 years.

Kind regards from Dämmunsinn

Hello Dämmunsinn

No, no; an oil heating system is not a solution/alternative for me.
Because I:
1. Have no room for the oil tank
2. Oil prices will rise massively sooner or later anyway (oil is currently way too cheap)
3. It makes no ecological sense to use a non-renewable energy source (this is my personal opinion)

That is why I want to know what makes sense or not regarding a water analysis.

And if the entire underfloor heating ever really fails (= e.g. leaking everywhere, etc.), you can still install radiant heating systems or raise the floor by 5-10cm and install a new underfloor heating (the room height would allow that).

Hello Fujiutsu

1. I don’t know about water analysis, what is it supposed to be good for?
2. Oil is still the cheapest energy. Until today, no one knows where it comes from. When they say there will be no oil left in 40 years, that is just scaremongering. Humans always react quickly to that. (see swine flu, for some a huge business)
3. Wood chips or pellet heating systems will never come into my house. Because wood chips and pellets have a large surface area and absorb moisture from the air and mold.

Hello Fujitsu

As a rule, a underfloor heating system must be flushed every 10 years at most, depending on the pipe material (plastic, copper, composite pipe ...).
If you had good values and little sludge in the pipes during the last flushing, you can wait longer for the next flushing.

A water analysis is then also useful again and serves as a basis for the decision for the next flushing.
