I recently installed a Wallace DT30 in my E34-2. Outside the cabin sitting in the cockpit you can barely hear the exhaust or fans running. Like any forced air heater there is a little noise from the heater outlet ducts more so when on high and the fans are blowing full speed. It's been consistantly dipping into the 30's here in Seattle and the heater can keep the boat around 65-70 at those outside air temps. It takes a while because I'm heating the entire boat. One of the first things I did was remove the doors to the V-birth so that area is always open. Both heater outlets are on the bottom of the engine cover. I put the heater return air inlet in the aft cabin to help circulate the warm air. When it's 40 deg or greater I can get the boat up to 75-80 deg. I'm a live aboard and primarily use electric heat. I also have a dickenson p9000 propane fire place. When it's in the low 30's If I don't use the electric heat and just use the propane fireplace and the forced air diesel heater I can get the boat up to 80 deg pretty quickly. I sometimes wish I had gone with the larger DT-40. The E34-2 is not an easy boat to run 3" duct through and I wanted to keep my runs as short as possible. I'm very happy with the product and service from Scan marine.
