This Bayfield 25 sloop is located in the Chesapeake area. Engine compartment space is always at a premium on sailing vessels. The only location this owner found involved mounting his Xtreme Heater upside-down. While we suggest mounting our heaters lower in the bilge, this is because heat rises, and it can be more efficient. IN this case, the heater is dropped down a bit into the engine space, which helps with air circulation. Xtreme Heaters can be mounted in any orientation. Xtreme Keeps Chowan County Water Search and Rescue operations ready to go, no matter what conditions present. I am glad to count on the Xtreme Heater to maintain a constant heat in my engine room. This is special.
