Of course not. Main advantage is to get about same
temperature with oil and water, as Jos wrote. Ideal
temperature will be achieved also as soon as possible
and keeped there with the help of a water thermostat
(which is a separate equipment).
Engine pre-heating system is electric (mains 230 VAC
or 110 VAC) as I wrote. Total power is 550W.
This is also a separate equipment and it is equipped
with a thermostat also. There is power enough to
heat also cockpit /panel especially if the engine
cowlings are coverred by heat insulated blanket or
other separate cover as the wings and other flying
surfaces. That is common practise here in Scandinavia
(if you keep your plane outside). It is possible also to
add a separate heat blower in the cockpit and connect it
to the same wiring loom as engine pre-heater. It is weight is
about one kilo and it is not fixed. It is also equipped with a
thermostat and overall structure is safe enough to use in a
cockpit (do not cover it anyway!).You take it away before flying.
The prices for all previous components without tax:
- big heat exchanger 359 euros (this is for Rotax 914)
- smaller heat exchanger 300 euros (for 912 and 912S)
- water thermostat 316 euros
- electric water heater 550W with thermostat 144 euros
- electric cockpit air heater 1200 W with thermostat less than 50 euros
Mr Pertti Lehtinen will do happily also international shipments.

Subject: Europa-List: Heat exchanger

> Got some more pictures today, decided to make a new subject, because this is
not really about pre-heating a rotax, although it makes it a lot easier and more
reliable. So to recap: This heat-exchanger will be mounted instead of the oil
radiator. Not in the same physical place. An oil thermostat is also superfluous
because the oil temperature will be closely coupled to the coolant temperature.
Since the water will warm faster then the oil, this helps to keep the whole
engine at a nice temperature. There will be a water thermostat as well. The
dimensions show up in the attached photos, weight is 826 grams. Price quoted
to me is 359 Euros without tax. For info contact info@aerotecno.fi, Pertti
