In the colder months looking after your boiler correctly is imperative, not storing the unit appropriately can cause issues with the function of the boiler, ultimately leading to increased time on site and an increase in cost. In ideal circumstances the unit should be stored indoors in a temperature above 5 degrees, however if this is not possible a number of preventative measures are advised.
If the unit is stored in temperatures below 5 degrees or outdoors the pump and boiler must be flushed through with anti-freeze.
As a rule, anti-freeze mixed at a 10% volume should be pumped through the system until the water coming from the outlet is pink. The unit should then be drained which will leave any retained water treated with anti-freeze.
After the boiler has been used and the anti-freeze washed out this process should be repeated before putting the unit back into storage.
Hot Water Boilers:
The same process as the above should be undertaken for hot water boilers, we also recommend covering the diaphragm pump with some form of insulation blanket which will prevent any moisture from the compressor freezing.
Once the unit has been used and the anti-freeze washed out the above process should be repeated before storing again.
Small Hot Box:
If the unit is stored below 5 degrees it will also need treating before use.
As the Hot Box has no pump it is advised that anti-freeze (10% vol) is pushed through the unit either using an external pump, airline, or simply by gravity.
Again, once the unit has been used and the anti-freeze has been eradicated the above process should be undertaken before putting the unit back into storage.
Premium Hot Box:
If it is not possible to store the unit in temperatures above 5 degrees you should ensure that both the re-circulation and water inlet systems are flushed with anti-freeze (10% vol).
Once the unit has been used and the anti-freeze washed out the above process will require repeating before storing again.
We also recommend that all boilers are serviced annually to keep on top of any maintenance that is required, and we offer a full Service & Repair facility at RSM.
