Hot water from engine

Bought a 285 bayliner the water heater was blown , to conserve space went with a small electric tankless (no good) .We were on a house boat last summer the hot water came directly from the engine ( no resivoir) used the water from the lake.

Anybody, have this set up ,is it hard on the engine ?pros? cons ?

Re: Hot water from engine

the usual is a loop from the engine through the water heater so that the water heater is warmed. this is a heat exchanger so no engine water makes it to the water tank. In my system, the engine is glycol cooled. hot glycol passes through the heat exchanger in the water heater before it goes to the sea water heat exchanger for massive cooling. There is also a circuit of hot glycol passing through a reverse cycle heating system for the air conditioners.
