Versatility. Used with remote air handler or gas furnace.

As the upgrade to our popular Envision product line, the 5 Series® carries some of our best features and efficiencies. The 5 Series upholds the standards we’ve set over three decades and the trust associated with the WaterFurnace name. Every unit is computer run-tested to ensure flawless performance at start-up—and in the unlikely event your equipment needs service, it’s backed by the best warranties in the industry. The 500R11 features advanced components to offer a level of comfort and savings that’s far greater than any ordinary system and represents an amazing 25.3 EER and 4.4 COP.

The 500R11 is engineered for use where an all-in-one unit would be difficult to install, like attics or crawl spaces, and is the perfect solution for retrofitting existing homes. By connecting to the WaterFurnace NAH Air Handler, the 500R11 can provide ultra-efficient heating, cooling, and even a portion of your home’s hot water. The 500R11 is also great for use in extremely cold climates where a dual fuel application is ideal. The unit uses the clean, renewable, comfortable energy from the earth and switches to fossil fuels only during the coldest parts of the winter. It’s ENERGY STAR rated and was developed in the HVAC industry’s only in-house EPA/ENERGY STAR Recognized Laboratory. Tap into the earth to achieve a level of comfort you have to experience to believe.
