Yes - I confirm:
ALL the Finnish Europas have
water thermostat, water-oil exchanger
and electric water heater as Jos wrote.
Some months ago I listed the benefits
of the electric water heater.
ALL water cooled engines should also
have water thermostat. That is a matter
of course in cars - why not in planes
with water cooled engines also?
I think most water cooled aviation diesels
have thermostats.
Reasons are about same when using
electric heater before cold starting:
- reduces engine wear = money to your pocket
- reduces fuel consumption = money to your pocket
- increases the power of cabin heater = safety and convenience
- reduces pollution = you have a place where to fly
All the engines burning fuel love to operate in
certain fixed temperature and also like to achieve
that temperature asap. One of the main benefit of
water cooling is its easy and automatic adjustable
temperature control by thermostat.
I have heard some Rotax-users in Sweden use same
combination and are happy. So will we, Jos and me!
Se on moro, Raimo
