Coal boilers are automatic with self feeding from the fuel storage hopper – they are set up to remain “lit” at all times. Hoppers come in all sizes: 500kg to 3 tonne as standard but other options are available.

The embers remain in the boiler (safely) for hours and re-ignite when heat is called for. The only tasks that are required by you is the removal of ash and occasional cleaning.

The boilers are designed to achieve optimum combustion efficiency – this means they remain smokeless while operating, and particulate emission so low that they surpass the Ministry for the Environment and most Local Body standards.

Every coal boiler heeds a hopper – our quality coal hoppers are designed to stand the test of time. Standard hoppers come in capacities ranging from 100kg to 3 tonnes.

All hoppers over 100kg are fabricated from 3mm mild steel, factory finished with metal primer and complete with a lighter Galvanized sheet lid.

Custom made variants are available for those installations that require differing sizes and/or configurations – please complete the form to the left to discuss your coal hopper options with one of our team.
