Vattenstand for a wood electric combi boiler
Hi
Sorry to post in English, but my Swedish is bad enough that you will probably prefer it if I stick to English... I moved here from the UK and I'm working on learning Swedish
I bought a house this year which has a wood electric combi boiler (CTC El combi) with a couple of water accumulator tanks. The system is working ok running on both wood and electric, but I've noticed on the front of the boiler the vattenstand (tryck) gauge seems to read rather low. I've attached a picture.
Can anyone tell me if this is ok, or a problem? Although I said the reading is low, this is guesswork on my part as I don't know what pressure these systems should run at.
If the pressure is too low, how could I increase it?
Many thanks

This a gauge for the watersystem for radiators/heating system.
The pressure should be approx. 1 bar for 10 meters height. I.e from position of the gauge up to the highest point of the system.
This under the circumstances that you have a "open system" with a expansion tank in the attic.
To raise the (static) pressure, just fill some water to the system, normally you will have indication/overfill pipe coming from expansion tank, in order to check when tank is full and/or a gooseneck on the rooof.

Thanks Roland, that's a good explanation and helpful to me. I've now discovered where the valve to add water to the system is, also where the overflow pipe drains into a sink in my garage, so can fill the system up to add a little pressure. I appreciate your assistance.
Please be aware, that, if you has to filled quite often, let's say once or twice a year, whitout to have been working with the system, you might have a leak somewhere in the piping system.
It doesn,t need to be a lot, just as small as it evaporate by the time, still it could cause damages if goes on, year after year.
