Verticell 200 L No hot water

[G_manon]

Hello,

I have a Verticell 200L which recently stop giving hot water even though the input flow is hot.  The thermometer in the boiler indicates 34 °C and doesn't get hot.

The hot water temperature is set to 55 °C for both, day and night but the water in the boiler doesn't get warm.

Any recommendation of what could I do to fix the issue would be appreciated.

Thank you

Übersetzt mit Google:

At first glance: It's clear that the pump is defective and is pushing the heating water into the pipes with maximum gravity.
At second glance: There could be air in the charging line. Or, if present, the changeover valve is stuck.

Thank you for your reply Franky,

Does that mean that there is not quick or easy fix for this, right?

and I need to check with a technician. Correct?

Thanks again

Which system is actually installed? Because you can check the air in the line yourself. Changing a pump or switching valve is more demanding.

It is a Verticell 200L not sure what model. Picture

Could you advise, how can I check the air in the line.  I would appreciate it.  Thanks

So with a separate charging pump? Here you could measure whether there is any voltage at all. You may also be able to use a screwdriver stoscope to check whether the pump is turning.

Thank you Franky,

Not sure that I can do that, I might need an specialist.

Maybe it would be better to contact an HB.
