HEATING LINE

The expansion vessel for heating systems makes available the volume for water dilation due to temperature increments, and keeps the system safe to dangerous pressure variations.
The working of the expansion vessels is more important during system start- up, when water temperature rises very quickly

Frequently Asked Questions

What to do when the water stinks?

Here are two solutions for you:

  1. Check and adjust the precharge pressure;
  2. The gum must be used for a period of time before losing its characteristic odor.
what to do if the expansion vessel loses the pre-charge pressure?

Check and adjust the precharge pressure.

Can I request the issue of a duplicate certificate of conformity?

Send the photo of the label for the certificate request to: varem@varem.com

What to do if the pre-charge values are over the limit declared on the label?

If the value is higher than the maximum precharge of the vessel, our products are not suitable for the application.

What is the country of production of the expansion vessels?

Our pressure tanks are all produced in Italy with the exception of the Plusvarem 25bar.

Can I use expansion vessels with temperatures over 99 ° continuously?

No. Our Solarvarem range can withstand temperature peaks of 130 ° C (3-4 hours a day). Temperatures are also affected by the presence of glycol in the system.
