Wabasto Furnace

[davidbrady]

If I recall correctly, the Wanderlodge M450 had a similar system. Some tried to isolate the engine from the system but with the decrease in boiler coolant volume the furnace would short cycle with the boiler coolant heating up quickly and cooling down quickly.

If the reservoir is too large than it takes too long to heat up, if it's too small then it heats and cools too quickly and the furnace fires at a high frequency.

For those who don't know, th Aquahot also contains a Webasto furnace along with a domestic hot water loop and an engine preheat loop.
