AquaStar Instantaneous Water Heaters
AquaStar water heaters have thermostatically controlled burners, which make them a good choice if your water is already heated or preheated by a wood stove or solar thermal collector. The New AquaStar 38 is their smallest water heater and is great for single fixture applications. The AquaStar “S” series, available in Model 125 and the standard Model 170 are designed to back up a solar water heating system, so its burner will adjust itself from 0 BTUs to full output to heat the water to your desired temperature. Other AquaStar models modulate from full out put down to 50%. The 125L is designed for recirculation systems, where water is pumped from a pressurized storage tank through the water heater and back to the tank. This system is often used in radiant floor heating and snowmelt systems. (The 125L requires a smaller pressure drop to activate the burner. Aquastar’s newest model, the 125X, is just like the 125B but has a battery sparked ignition unit.) 10 year warranty on the heat exchanger and a 2 year warranty on all other parts. AGA listed.
