Looking for energy efficient heating and cooling solutions? Geothermal heat pumps are similar to ordinary heat pumps, but use the ground instead of outside air to provide heating, air conditioning and, in most cases, hot water. Because they use the earth's natural heat, they are among the most efficient and comfortable heating and cooling technologies currently available. Earning the ENERGY STAR means products meet strict energy efficiency guidelines set by the US Environmental Protection Agency and the Department of Energy.

Take a glance around your home and you'll see a thousand reasons to protect what you've worked for: treasured photographs, a piece of furniture passed through generations, and most important those who matter most to you. You've earned the lifestyle you lead, and now the name you've trusted in your home for decades will help you keep everything running in the event of a power outage. Power loss is more than an inconvenience - it can quickly affect the safety and security of your family and your possessions.

Hot water for any size home endless supply with more volume - not only can a tankless water heater provide an endless supply of hot water, it can also deliver more of it for all your hot water demands. With this much volume, tankless water heaters can meet any hot water demand of today's homes. No dirty tanks with a tankless water heater, water is heated as it passes through the unit so you will always be using a fresh supply of water. As the years pass by, traditional tank water heaters start to rust and build-up scale inside the tank, which is where your hot water is being stored for use.
