INFORMATION
Risk of space heating capacity shortage for domestic hot water tank without internal
booster heater: In case of frequent domestic hot water operation, frequent and long
space heating/cooling interruption will happen when selecting the following:
Tank > Heat up mode > Reheat only.
INFORMATION
When the DHW tank mode is reheat, the risk for capacity shortage and comfort
problem is significant. In case of frequent reheat operation, space heating/cooling
function is regularly interrupted.
In scheduled mode the DHW tank produces hot water corresponding to a schedule.
The best time to allow the tank to produce hot water is at night, because the space
heating demand is lower.
