    The Mascot LX is an all-in-one, wall-hung, space heating boiler and tankless water heater 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.

    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.
