Adding water to my CV

[lg.alessio]

Dear all,

First I apologize for posting in English but my Dutch level is still very basic.

Recently, I bought a house with a central heating system Daalderop combipact 24/35 and after I bled the radiators, the pressure dropped to 1 bar.
I tried to find information about how to add water to the system but I couldn't find it in the manual or this forum.
Can someone let me know how to do it, please? I guess I am allowed to do it myself without calling a specialist.

I think that I should connect a hose to the inlet just under the red valve. Is that correct? That seems to be the hot water line that goes to the radiators.

Thanks in advance!

Kind regards,
Luis

No, do not use the red valve.

The red valve is a safety part of the system.

Do you have a picture of the lines on the right to the Daalderop system?

Nothing in the pictures.

Do you have a filling hose ? (cv vulslang)
Do you see a fosset or tap that can be used to get the water from?
Often a washing machine tap (wasmachinekraan) is used.

Thanks everyone for the quick replies!
I don't have a cv vulslang, but I can get one.
I have a water connection for the washing machine nearby.
Here are some pictures of the right side of the Daalderop. There are two valves next to the pressure tank. One in the hot line and the other in the return line.

" There are two valves next to the pressure tank "
That's were you fill it.

Now you just need a "cv vulslang"
Normally it's left near the cv, but some take everything when they move out.
Sometimes a normal garden hose is used.

The connection on the valves should be the same as the one for the washing machine, so a standard filling hose can be used.

Alright! I will try it out with my garden hose then.

Thanks a lot for your help!

Make sure you fill the hose with water first,
just let it run into a bucket before you connect it, else you can force a lot of air into the system.

That's a good advice. thanks once again!
Can I use the same connection to drain my CV system for working on the radiators?
