Laars Mascot® ST Condensing Tankless Water Heater

Laars introduces the new Mascot ST condensing tankless water heater. The natural gas or LP-fired unit offers an ultra-high 0.96 EF (energy factor) efficient stainless steel heat exchanger, full 10:1 modulation, is available in a 199 MBH size and produces a plentiful supply of domestic hot water to meet the needs of the modern home.

The innovative condensing heat exchanger is a self-cleaning design that allows condensate to flow down along the tube walls and out through condensate collection system. Uniform heat distribution also reduces stress points in the heat exchanger. Combined with erosion–and corrosion–resistant materials, the result is a durable long lasting design.

Packed with features, the Mascot ST includes an advanced control system, primeless condensate trap, zero clearance installation and venting up to 100 feet in PVC, CPV & Polypropylene. Learn more at
