Storage tank
Using a storage tank
The larger water volume achieved with a storage tank makes the stoker running
in longer intervals, thus giving higher efficiency.
However, the cost of installing a new storage tank is normally not profitable
due to the extremely high thermal efficiency of the KMP stoker.
Installation on a boiler system using a storage tank
If there is a calorifier or a shunt valve in the boiler, the temperature sensor
should always be attached directly to the boiler, preferably in an immersed tube.
When the boiler and the tank are in direct-cycle, the water temperature should
not be below 60˚C when the stoker starts, otherwise condensation may lead to
corrosion of the boiler body.
If the calorifier and shunt valve is situated in in the tank, the temperature sensor
can alternatively be placed on the tank, this leading to longer running intervals,
thus minimizing the number of starts and stops.
Placing the temperature sensor on the tank
If the temperature sensor is to placed on the storage tank, the charging pump
system must have capacity enough to cool the boiler off sufficiently.
Boiler temperature must not exceed 95˚C before the tank temperature is about
80˚C (recommended temperature) and the stoker stops.
The cut-out thermostat must always be attached to the boiler!
Two temperature sensors can be used with PX22. Simply connect two sensors
via our junction box (accessories, art.no 1599) to the burner’s temp. sensor
connector. Then an authorised installer adjusts the start, stop and alarm temp.
in the Service menu.
