NO ONE BRINGS IT ALL TOGETHER LIKE LOCHINVAR: Lochinvar is the industry leader that other leading companies call upon for the most advanced and efficient water heating products in the world. For that reason, Lochinvar is trusted to go beyond the call of duty to find a solution for every project, no matter the size. You will not find a water heating company that works harder or cares more.

THE RIGHT INVESTMENT: If you’re looking for a heating system for your new home, replacing an old boiler, or thinking about converting from expensive electric heat, Lochinvar’s Solution heating boiler is the right heating investment for you. You rarely think about heating your home, that is unless you can’t get warm enough, or your monthly heating bill just surpassed your house payment. A reliable and efficient heating system is the key to keeping your family comfortable when the weather turns cold. That’s why Lochinvar developed the Solution. This gas-fired boiler stands above any other boiler in it’s class in terms of comfort, quality, efficiency, flexibility and dependability.

BUILT FOR DEPENDABILITY Every Lochinvar boiler is designed, assembled and engineered in the USA. Built to commercial grade standards, the Solution boiler is better designed and better built. And every Solution boiler is quality checked throughout the manufacturing process, giving you a boiler built for dependability. When you select Solution, you get home heating that is economical, reliable, flexible, safe and dependable. And we back it all up with our exclusive 20-year Limited Warranty

COST SAVINGS HIGH EFFICIENCY: Often times old boilers operate as low as 50% efficiency. This means that 1/2 of your fuel dollars are wasted up the chimney. A Solution boiler, with an annual fuel utilization efficiency (AFUE) of up to 84%, can reduce your heating bills by over 30%. This means that the Solution boiler can actually pay for itself in just a few short years with the money the old system is wasting. If you are currently spending $2,000 each year to heat your home with your old inefficient boiler, your fuel savings could be as much as $800 per year by switching to the 84% efficient Solution boiler. Lochinvar’s Solution boiler makes heating your home with gas a smart investment that you’ll appreciate for years.
