Phoenix Solar Water Heater by HTP

Phoenix Solar Water Heater by HTPThe Phoenix® Solar Water Heater from HTP is a revolutionary product that combines an internal solar heat exchanger with a 96%-efficient gas-fired back-up, all in one storage tank. When connected to solar collectors, the Phoenix Solar Water Heater harnesses the power of the sun to provide ample Domestic Hot Water while reducing energy costs and pollution. When the sun’s energy is not enough, the gas-fired back-up heat source engages, providing large quantities of hot water without consuming large amounts of energy, thanks to modulating condensing technology and a 96% thermal efficiency rating. The Phoenix Solar Water Heater is suitable for a variety of commercial and residential water heating needs, including hotels, apartment buildings, restaurants, laundry facilities, schools, homes, and more.

Key Features

  • Minimal energy costs - solar energy provides 50-75% of your home hot water needs

  • Environmentally conscious - each solar panel prevents tons of carbon dioxide from being released into the atmosphere -- the equivalent of planting more than 40 trees

  • Built-in gas back-up - when the sun is not shining, the gas burner provides ample hot water while operating at 96% Thermal Efficiency and 93% Combustion Efficiency

  • High system efficiency even during low load conditions - the modulating burner operates at a 5 to 1 turndown ratio, matching fuel consumption to demand

  • Improved component life and reliability - modulation, along with thermal mass, eliminates the short cycling effect, which conserves energy and improves component reliability

  • Enhanced comfort and efficiency - weather responsive outdoor reset controls match the supply temperature to the heating need, preventing overheating

  • Appropriate for both residential and commercial applications - available in two gallon sizes (80 or 119 gallons) and 2 BTU inputs (130,000 or 199,000 BTUs)

  • Low standby losses - the tank loses only ½ degree Fahrenheit per hour when the burner is off, thanks to 2” of environmentally safe foam insulation

  • Virtually maintenance free operation - the robust material and sophisticated design of the heat exchanger minimize lime and scale buildup, eliminating blockage risks

  • Incredible system flexibility - built-in auxiliary taps provide connections to air handlers, radiant heating, or supplemental storage tanks

  • Optimum serviceability - a removable casing provides service technicians easy access to components

  • Quality construction - an extremely durable cupronickel and stainless steel heat exchanger boasts excellent heat transfer properties and resists corrosion, while the robust 316L stainless steel tank eliminates the need for anode rods

  • Excellent venting options - uses inexpensive, easy-to-install PVC or CPVC pipe, with vent lines up to 85 feet total equivalent length

  • Self-diagnostic electronic control - displays digital readouts for water temperature, set point and differential

  • Eligible for tax credits and utility company rebates - based on high efficiency ratings
