ESPAR heat

Does anyone have expeience with an ESPAR diesel heater integrated into an existing AC system? Does it work properly, create unpleasant odors, require maintenance? Any general comments?

A, it seems you are asking two separate questions. Re: Eberspracher/Espar operation generally, they make both heated water and heated air systems. The techs I''ve talked with work much more on the water systems, and recommend the air system for longevity. These were redesigned some years ago to due a start-up cycle with far less current draw (which used to be a performance problem when boats were out on the hook or without a dock plug); that was problem we had with ours. Operation is dead simple (adjust the thermostat; turn it on/off) and the heated air is usually drawn from within the boat and is sealed from the combustion process, so it is safe and without odor.

The only integration with an existing HVAC system I can imagine is share the ducting. How easy/hard that is to arrange will depend on the given boat, ducting arrangement, and no doubt will involve some kind of flapper valve, since both systems will have their own air blower motors that are integrated into their respective control circuitries.

Thanks. Sounds like the air system is best, which would be our situation anyway.

We have dual heated air supplies using a common duct system. One is the conventional Espar air heater. The other is a Volvo QL heat exchanger that uses the closed 50/50 glycol loop on the engine to heat air which is then blown into the same duct system. It has it''s own three speed fan. We have a flapper valve as Jack suggests that is re-positioned depending on which heat source is in use. We have no experience with air conditioning however it would seem easy enough to rig something similar.

I highly recommend utilizing engine waste heat for cool climate cruising. It''s a great way to warm and dry things out whenever motoring.
