1

Select a tank size (gallons of capacity) which is about the same, or somewhat larger, than your boiler horsepower.

2

Select your construction materials. A steel tank with cast iron/bronze fitted pump(s) for the lowest initial cost; or an all stainless steel system for long life and best value. Steel tanks have an average life of 3-6 years. Stainless tanks are warranted for 20 years, and may be the last tank you ever need to buy. Cast iron/bronze fitted pumps are warranted for 1 year; stainless pumps for 5 years.

3

Decide whether you need a simplex or duplex system. A simplex system (one pump) typically needs no control panel because most boiler manufacturers include motor starters in their control panel. But if you decide to go this way, keep a spare pump available to avoid down time.A safer alternative (if downtime is critical) is to install a duplex (2 pump) system with alternating control panel (optional). The control will alternate pump use and if a pump fails, allows you to flip a switch, and the remaining pump will keep your boiler operating while you repair the defective pump.

Our complete system includes: tank, stand, make-up valve, sight gauge, drain valve, pump(s), isolation valve(s), inlet strainer(s), and piping
