Cooling from the water heater alone:
During tapping, the level of cooling will Typeically be 30–35°C. When
hot water is not being tapped, it is completely normal for the return
temperature from the water heater to rise slightly. In this situation,
the district heating meter will register very modest consumption as
the volume of water is very small.
On water heaters with recirculation, the calorie meter registers the
heat loss in the circulation pipe.
Tightening of connections
Retighten all connections after reading of the heat meter. If case of
leaks, contact your professional provider for assistance.
Please note that the connections may feature EPDM rubber gaskets!
Therefore, it is important that you DO NOT OVERTIGHTEN the
union nuts. Over-tightening may result in leaks. Leaks caused by
over-tightening or failure to retighten connections are not covered
by the warranty.
