Slant Fin Boilers Features Analysis

There are three things to note about Slant/Fin boiler features:

Slant fin makes two electric boilers, the Monitron EH and Monitron Deluxe. These systems are sometimes installed where no other fuel source is available. However, electric heating is the least efficient and most expensive type of heating. Slant Fin markets its electric boilers as backup boilers for oil or gas systems when fossil fuel isn’t available in the short-term. The units can run on generators.

Slant Fin is one of only a few large boiler companies that makes entire hydronic systems including baseboard radiators, not just the boiler system. There are standard baseboard units and the Decorator Series of attractive radiators with baked enamel finishes in a range of colors. It’s worth noting that the company began as a manufacturer of radiators with a slanted fin design. It began making boilers more than 15 years after its founding in 1947.

Several Slant/Fin boilers are available in pink as part of the company’s Heating for a Cure charity that supports the National Breast Cancer Foundation. This includes the Sentry S-90 and S-120 boilers.
