The ups and downs of oil

If you’re looking for a new oil furnace or boiler, it’s probably because you want the most efficient heat source you can find. But what if the cost of oil goes up? Your heating costs will rise with it and there’s nothing you can do but grin and bear it.

Balance your resources

With a Benjamin Combination, you can enjoy the convenience of oil when oil prices are down, and switch to costsaving wood when they’re up—all with one unit that takes up the same floor space as an oil furnace or boiler.

Benjamin Combination furnaces and boilers provide up to 85.3% efficiency when burning oil. When it’s cheaper to burn wood, or when there’s a power interruption, you can easily switch fuels.



Choice and Convenience

Some people prefer to burn wood most of the time. Whether you do it often, or only occasionally, you won’t sacrifice efficiency with a Benjamin Combination. And if you’re away for an extended time, the oil burner will automatically kick in. So you can think of a Benjamin Combination as having oil with wood back-up, or the other way around. It’s your choice!

Small Package. Big Value.

Benjamin Combinations are compact, one-piece units with the same footprint as an oil furnace or boiler, and designed to use one chimney, so you can likely replace an oil furnace or boiler without major changes. That saves you money on installation.
In addition, a Benjamin Combination is a good investment, giving you peace of mind and paying for itself by adding value to your home.

Choice, efficiency, convenience, value...

Now the only question is, why would you choose an ordinary oil furnace or boiler, when you can have an extraordinary Benjamin Combination?
