“I've owned the bl2840 for four seasons. I bought this outdoor wood furnace when Lp was over 3 dollars a gallon and a year or record snow and cold, while only keeping the thermostat only at 68. Since then the house stays at a comfortable 74. I also heat hot water and a three car garage. The bl-40 was not the biggest model to choose from at the time. After talking with the folks from Portage and Main. They sized the boiler to the heat load saving me money and wood. The features I like about bl 2840 are the sleek design the amply sized doors and the heat exchanger along with the refractory brick used inside.”
We purchased the Ultimizer bl2840 6 years ago and we are very pleased. With 2 teenagers taking long showers the furnace has been working great! All the mess is outdoors. It is nice not to hear the oil furnace come on all winter long. Especially with the price of furnace oil that goes up in the winter. Oh, the money you will save. The customer service is great too!
The Ultimizer wood series is the product of more than 40 years of research and development that has earned Portage & Main Outdoor Boilers the reputation as an industry leader.
