How to assemble the heater kit of a boat

5 steps to install the heater kit on a boat’s engine

Sole Diesel has developed this kit to use the coolant liquid of the marine engine, in order to exploit the excess heat from the engine to use the heat for any desired application.

This heat intake kit is used to recycle the excess heat of the coolant water of the marine engine and use it to heat the boiler as well as other applications such as building a distiller of sea water and produce fresh water suitable for showers, deck cleaning, running water…(undrinkable).

This way, by avoiding having to turn on the electrical heating, we save a lot of energy.

This manual is valid for marine engines Mini 17 (serial numbers over 35102) and Mini 29 (All engines.)
Kits for other marine engines have it’s own installation manual
