(NewsUSA) - With the memory of last winter's harsh heating bills still vivid, North American property owners would do well to embrace proven cost-saving energy efficiency and conservation practices.Space and water heating can consume up to 80 percent of a home's energy use, notably in northern climates. So, a high-efficiency combination space and domestic water heating system is the right home-heating choice for the times, according to Marathon International, the exclusive distributor of Baxi heating and renewable energy solutions in North America."These heating and renewable energy systems have enabled property owners throughout the U.S. and Canada to generate significant energy use and utility cost savings over the past two decades," says Marathon International president Mike Thomas.Up to 98 percent energy efficient, combination gas boilers typically save upwards of 35 percent. On the high side, a Long Island resident is saving over 70 percent annually with a Baxi combi gas boiler, which reduced his previous inefficient oil boiler bills by $3,500.

"Our Energy Star-certified Luna Duo-Tec is the only boiler with gas-adaptive technology. It not only ensures proper initial set-up, but also sustains high-efficiency performance for the life of the appliance."The boiler is so quiet that it is approved for closet installation. It has multiple built-in performance enhancement and safety components, such as gas-adaptive and self-calibration technology. It can be used in a range of applications, including in-floor radiant, hydro air, radiators, towel warmers and snowmelt systems.Before investing in the right heating solution for their property, Thomas advises homeowners to talk first with a qualified heating and plumbing installer with gas experience. He further recommends that property owners get an energy efficiency audit, covering their older heating appliance, as well as insulation, windows and doors."Above all, make sure contractors are trained, certified and accomplished in the installation and servicing of the equipment they recommend," says Thomas. "Do they offer annual maintenance and an optional extended parts and labor protection? What utility rebates and other energy-efficiency incentives are available?"Choosing the right heating appliance, properly installed and maintained, is key to achieving energy-efficiency and conservation success.
