The Dayton 5PV22 Hydronic Unit Heater, model number 16-18, is a compact and efficient heating solution for small to medium-sized spaces. This heater is ideal for applications such as garages, workshops, greenhouses, and other areas where heating is essential.
The Dayton 5PV22 is a cast-iron, direct-fired, hydronic unit heater, which means it uses hot water as its heat source and distributes the heat evenly throughout the room via cast-iron fins. The heater's 16-gauge steel housing is both durable and corrosion-resistant, making it well-suited for demanding environments.
The heater comes with a factory-installed 180,000 Btu/h input rating, making it capable of heating spaces up to 2,500 square feet. It features a modulating burner, which allows for precise temperature control and efficient operation. The heater can be controlled manually using the built-in temperature control knob or remotely using a thermostat (sold separately).
The Dayton 5PV22 is designed for easy installation. It comes with a factory-assembled, factory-painted cabinet and a factory-installed igniter and flame sensor, reducing the amount of on-site assembly required. The heater also includes a factory-installed 1/2-inch NPT connection for the water supply and return lines.
Additional features of the Dayton 5PV22 Hydronic Unit Heater include a low water temperature cutout to protect against overheating, a high limit temperature safety control to prevent excessive temperatures, and a removable, powder-coated, easy-clean combustion chamber. The heater is also equipped with a built-in condensate drain for easy removal of condensate water.
The Dayton 5PV22 Hydronic Unit Heater is a reliable and efficient choice for heating small to medium-sized spaces. Its cast-iron construction, modulating burner, and easy installation make it a popular choice for contractors, engineers, and DIYers alike. With its factory-assembled cabinet, factory-installed igniter and flame sensor, and easy-clean combustion chamber, the Dayton 5PV22 is a smart investment for anyone looking for a dependable and cost-effective heating solution.
