... a hot thick fire

and therefore speedy evaporation.
That’s the secret of boiler firing.

But you cannot get the best results
from the natural draught —that is,
chimney draught. A chimney relies
upon hot gases for its drawing power—
and that’s waste.

These hot gases should be utilised
in the reduction of your fuel bill.

The “Cyclone”

Induced Draught Plant

gets the maximum from the fuel. It
helps you to use cheaper fuel. And
it means—all the time—economy with
efficiency.

We now use only the one Boiler, have reduced the
