System examples
The following examples are only meant to give an indication of the possibilities available with
the THISION-L/R40 water heater. These examples can not be used in a project without any
further analysis of the project situation by an authorized company.
System 1: water heater with buffer tank
Water heater connected to a buffer tank, with the cold water feed connected to the return
connection of the buffer tank. This is the most common way to connect a water heater.
Having the cold water feed on the return connection of the tank results in less start/stop
sequences of the water heater and creates a stable temperature control in a normal hot
water installation.
System2: water heater with big buffer tank
When having temporary peak demand, it’s useful to have a big buffer tank (or multiple
smaller tanks in series) in combination with a small water heater capacity. The capacity of
the water heater is determined by the maximum loading time of the buffer tank.
