The heat exchanger is made of one or two rows of coils with aluminum fins, with approximately 10-1/2 fins per in |
The spacing between the fins makes cleaning and maintenance of the heat exchanger easier, which is essential to keep the unit heater efficient |
The standard steel tubing is very strong and long lasting |
Steel tubing is designed for hot water applications up to 150 psi |
The copper tubing used for the heating coil is very thick (0.03 in), making Reznor heating coils extremely sturdy and long lasting |
The large tube diameter reduces the water pressure drop, which means these units require lower pump pressure than other hydronic heaters |
It also allows a very rapid heat radiation |
Heat exchangers are subjected to a pressure test at over 350 psi (25 bar) before leaving the factory |
The standard 2-speed motor is a hermetically sealed motor which is maintenance free |
The motor is wired for 115/1/60 supply voltage |
The motor speed is field adjustable to run at high or low RPMs |
The flexibility of changing motor speeds allows the installer to adjust the unit to high speed for increased Btu/hr output or low speed for reduced noise level |
All motors have internal protection as a standard feature |
All model WS units can be installed for either vertical or horizontal |
