5 Series Forced Air (500A11)

5 Series Flagship Heating and A/C Geothermal Heat Pump

The Most Efficient WaterFurnace Product in the World

As the upgrade to our popular Envision product line, the 5 Series® carries some of our best features and efficiencies. Its advanced components offer a level of comfort and savings that’s far greater than any ordinary system and represents the industry’s highest efficiency two-stage unit at 30 EER and 4.8 COP.

The 500A11 carries the Energy Star Most Efficient 2015 designation and was developed in the HVAC industry’s only in-house Energy Star Recognized Laboratory. It provides forced air heating, air conditioning, and even generates a portion of your home’s hot water—all from a single unit. Replace your fossil fuel furnace and noisy outdoor air conditioner with a system that uses the earth as its fuel source.

The Symphony system, by WaterFurnace, is a complete system monitoring package that internet enables the entire unit, giving you access to all the data you need, where ever you need it, to not only control, but monitor and troubleshoot your WaterFurnace. Symphony is cloud-based, so there’s no software to install and provides control over your entire geothermal system - not just the thermostat as in other ‘smart thermostat’ systems.
