The boier runs on the exhaust from the engine. Not vice versa.

The boiler heats the fluid input to the engine, the fluid condenses and
heats the CH water.
There is a second stage in the boiler that further heats the CH water.

Make sure you use it for a low temp heating system so the condenser works
well and the boost isn't used much.

You ARE in Lala land Denise.
