Pressurize vaillant ecotec plus vhr

[PierreP]

Hi,

I would like to pressurize my boiler (vaillant ecotec plus vhr) and I don’t know how to proceed; maybe somebody could help?
I watched some videos on the internet and it seems that some vaillant models have valves underneath the boiler but it is not the case with our model, we only have the little screen with 4 buttons and I cannot find how to adjust the pressure which us stuck at 0,5 bars now.

thanks in advance,
Pierre

Hello Pierre,

Have a look more around those pipes that are further down, nothing visible so far. Do you have a cylinder anywhere? There’s no isolation valves on that, so not the best install.

Hi,

thanks for your reply, no nothing visible, no valve no cylinder… I’ve spent an entire day looking for a mamoneter or a valve, somewhere in the house, connecting the water circuit to the heating circuit, but I’ve found nothing. Could it be that the pressure could be directly regulated from the boiler? But how?

No, it won’t be regulated by the boiler, It’ll be x2 valves somewhere.

Ok, I can’t see them…
Although, I don’t get how they could have installed and pressurized the boiler without these valves.

They won’t have.

Ok, just checked again and I can’t see any valve in the pipes connecting to the boiler. Could they be elsewhere? I mean would it make sense?

They can be anywhere on the heating pipe and cold water pipe, I’ve found them in a kitchen cupboard before now, just needs a bit of detective work.

Bearing in mind this isnt a UK boiler, or UK install, so may have internal/auto filling or other means of pressure regulation.

Thanks @ScottishGasMan, I wasn’t aware of our European cousins way of filling
