  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 PX50 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 mini-
mizing 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!

The temperature sensor must not be located to low, in wich case the boiler might be 
overheated. 
If uncertain, make a test as follows: 
Run the stoker until boiler temperature reaches about 95˚C. Then measure the tem-
perature on different spots on the tank. Choose a place that is maximum 80˚C and 
where the sensor can be attached conveniently. A special storage tank control unit is 
as extra accessories.
