just bought a webasto 2010 and iwould like some suggestions on the setup, i thinking about putting it the ac bay as i have removed the coils and blower then using the original heater lines to move the heated water around the bus. i want to let it flow up to the dash to the defroster core then add a heater core near the center of the bus controled by a thermosat to heat the rest of the area? what size circulating pump will i need and were is a good place to purchase? can i just let the water flow to the engine to preheat and once the engine is running and up to temp the webasto should not fire up correct? does any one have a system set up this way? i read some systems are using a heat exchanger or the engine so a to keep the systems seprate but im trying to keep it simple. george b | ||

__. George, I'm planning a similar setup. I'll have "sources" 1) heater (in my case, "ProHeat") and 2) engine going into a manifold. __. There will be valve to completely isolate the engine so if there's a leak anywhere else in the system, the engine can still be run. It will also require some valving to direct the hot coolant from the manifold (to hot water heat exchanger, to driver's heater and defrosters, to main heater core and blower etc.) but this will be straight-forward. __. Dunno if the webasto is different from the Pro-Heat but I'm going to set mine up for manual control. I don't want mine starting up unless I know about it but of course the "overheat" shutoff will still function. | ||

I have a 2010 set up the way you are planning. I used a old circulating pump from a Fishbowl parts bus and hooked it between the 6V71 and the Webasto. I but a manifold with three shut offs. One zone goes to heat inside the coach, One zone sends the water to my heat exchanger on the side of the electric water heater. When driving down the road with the valves open the water circulates all three zones. I no longer use the circulation pump that is provided by Webasto because they are prone to not work and are expensive to replace. | ||

Bruce, We are using the ProHeat. The ProHeat is controled by a cube relay that is activated by power from our wall mounted thermostat. Our system is a single loop from the ProHeat through a heat exchanger (other side is engine coolant), to a heater core and 2 toe kick units inside the bus, then through a small core in the "water bay" before returning to the ProHeat. All fans are controlled by an Aquastat that turns the fans on when water reaches 120 degrees. We are completeing the installation and hope to have it finished by next week-end. Just our way, YMMV Jack | ||

paso 1 does your setup do a good job of heating the coach? | ||

George, I'm also using a DB2010 in similarly sized bus. Mine however is what I'd call a 'more conventional' installation. It does a very good job of heating and preheating, the coldest it's gotten here is 9f and it was cycling 10 minutes on 15 minutes off while maintaining 70f inside. I found room in the engine compartment, over the transmission to mount the boiler, engine heat exchanger, pumps and fuel filter. My heat exchanger ties into the engine coolant through 'tees' that replaced elbows below the valves on the front firewall. I built a 4 gallon polypropylene resivoir tank that sits in the right corner of the rear cap. I have 2 thermostats on walls, one in the bedroom, one on the dinette wall. 3ea. 7000 btu rated 'toe kick' fan coils are on the bedroom 'zone' with one actually in the bathroom. The front heating is by 2 7000 btu toekick fan coils under the kitchen counter cabinet and a 4 outpuct ducted 28,000btu fan coil for the driver-copilot area. I also have a domestic hot water heat exchanger in the hot water tank and an added flat plate heat exchanger for unlimeted hot water. The system is all 'plumbed' with heavy duty heater hose and includes a 3 way valve that bypasses the fan coils for summer water heating and a 120 degree aquastat to delay fans till the coolant is warm. The pumps I'm using are what Dick Wright of Wirco recommended and the work very well. Regards Jerry 4107 1120 | ||

I like your system of a heat exchanger to isolate the engine coolant (if I ever have a heater hose break, I'll have to close my engine valves and refill the engine coolant -- but my way is a little more towards the KISS system, for a simpleton like me). I hadn't figured out how to do the fan regulation and the "aquastat's" sound like a perfect solution for me. Thanks for that info! Best wishes, Bruce | ||

FYI .... Vehicle Systems (Aqua-Hot/Hydro-Hot) doesn't advise you to use their system for vehicle defrost, it should use the vehicle motor coolent. If their system quits while you are driving and you have no defrost it could cause an accident. Ron | ||

I hadn't thought of that but both our systems (Jack's and mine I'm talking about) use engine coolant for heat (to "heat exchanger" water heater, to defroster, to "room heat") when under way. I guess if for some reason that the engine wasn't putting out enough waste heat to provide what's needed, then the auxiliary heater could add some, but I can't imagine that happening. __. Jack's system would separate the coolant in the engine loop from the coolant in the auxiliary loop with a heat-exchanger; mine would share the coolant in a long loop. But both would use engine heat when underway in every situation that I can think of (correct me if I'm incorrect about your system, Jack). __. Of course, it would be possible to run the auxiliary to heat the engine, preheat the defroster, and warm the interior of the vehicle, resulting in better defroster/heater performance as the vehicle is started, but that doesn't change that the real energy when underway comes from the engine. | ||

Hi George Yes the system keeps the bus cozy but I have the webasto feeding a old front heater removed from a parts bus c/w new core and high powered fan. I heat only the back 20 feet and have to shut it off. I'm sure it would heat the whole bus but I have not tried. | ||

I had to replace the circulating pump recently in my Espar system and ended up with this Johnson pump. Its a better pump than the original at half the cost. I have it wired to run with the Espar system, or independently to improve circulation on the road and am very pleased with it. http://www.pumpagents.com/JohnsonPumps/10-24190-1.html tg |
