The newly enhanced ESP-Plus Tank selection program can size and select B&G expansion tanks using a direct method that requires minimal input. The program also offers a more helpful method with graphical step-by-step guidance in sizing the tank. The Summer 2007 issue of Counterpoint highlights the features of both methods. Read the full article in the current issue of Counterpoint.

It’s that time again to make sure your customer’s Series 100 and other 3-piece boosters get properly oiled. Following recommended oiling procedures ensures long lasting and quiet operation. There are three oil ports- two on the motor and one on the bearing assembly. We recommend using a B&G #20 weight non-detergent oil. One teaspoon per oil port at the start of each heating season is suggested. For more info, go to http://www.bellgossett.com/homeowners/BG-OilingSeries100.asp

The new Primary Secondary Header is a low-loss header, which simplifies primary-secondary circuit piping. Replacing the need for closely spaced tees as well as other costly components such as an air separator, air vent, strainer and dirt separator, the PSH saves valuable installation time. The PSH is ideally suited for installations with energy efficient condensing boilers. By hydraulically decoupling the flow in the primary and secondary circuit, each leg of the circuit can run at its optimal flow rate and temperature, raising overall system efficiency.

Prior to the 1920's, about 80% of the heating systems in homes were hot air and the remainder gravity hot water or steam systems. Steam gained in favor and there was a corresponding decline in the use of gravity hot water systems. One reason for this was that only one pipe was needed for steam whereas two were required for gravity hot water. Of course, there was the slow heat response of hot water gravity systems.

1929: Bell & Gossett became interested in the manufacture of equipment for "Forced Circulation Hot Water House Heating Systems". This type of system had marked improvements over the old gravity hot water systems. Through the use of a small electrical pump, circulation of heated water through the system was greatly accelerated.

1930: B&G begins selling a quiet "booster" pump for use in circulating water. In addition, automatic controls were added with the addition of the B&G Flo-Control Valve and Electrical Controls. This improved method of heating tied in perfectly with the use of a B&G Indirect Water Heater. During "off" periods of the pump, the heat stored in the boiler water was used to heat domestic tap water in the indirect heater. This combination was widely advertised and sold as the B&G Triple Duty Valve System. It had the virtues of furnishing controlled and rapid heat for the building during the winter and domestic hot water all year 'round, from a single boiler.
