Heat Exchanger - Webasto Air Top 2000ST Installation Instructions Manual

Marine heating system Installation Instructions
Install a bleed valve (automatic or manual): at high point or near difficult to reach locations; in
return line.

10.4 Heat exchanger

Possible heat exchangers:
Plate heater body: small weight, flat construction, even heat distribution, relatively large surface for
good efficiency, silent.
Convectors: good heat output with good air circulation and wide construction, silent.
Achieve fireplace effect. See illustration (side view).
When installing convectors, ensure there is good air convection
Blower heat exchanger: optimal heat exchange with compact construction, requires power.
Blower heat exchanger positioning: if possible, close to the bottom. Good accessibility (for
bleeding). Pay attention to sufficient fresh air supply.
Air distribution using hoses is possible. Hoses: keep them as short as possible.
Avoid air short circuits (intake of exhaust hot air).
Avoid air short circuits (top view): 1) Blower heat exchanger; 2) Air outlet; 3) Air inlet
