High-Efficiency

Mascot® LX

The Mascot LX is an all-in-one, wall-hung, space heating boiler available in 7 sizes to meet the smallest to largest home’s heating needs. Mascot LX efficiently transfers the most heat possible from your Natural or Propane Gas by using modern controls, a stainless steel heat exchanger and a very efficient condensing design.
The Mascot LX is also available as a combination (heating & hot water) unit in sizes 125, 150, and 175 MBH.

Stored heat that normally goes up the chimney as waste in traditional heating systems is recovered through the condensing operation by the Mascot LX and is returned back into your home. Save thousands of dollars over the life of the Mascot LX versus traditional lower efficiency units.

Open up your home heating possibilities, Open up to the Mascot LX!


The Mascot LX gives you the ultimate flexibility in home heating that an ordinary furnace simply can’t deliver.

Imagine heated floors, walls or ceilings that are the ideal temperature to the touch. No more hot or cold spots in your home! Continue outside with walkway or driveway snow melting or into your bathrooms with heated towel warmers - all can be heated with the use of the Mascot LX.

The Mascot LX can also be paired with an air handling system to provide hot air through your existing furnace ducts, and then, in-floor or radiator heating or perhaps that towel warmer can be added where you want it.
