Boilers - McKenzie Design

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.
