Every heating season we get, at least, a half dozen calls with the question above, which is the subject of today’s R. L. Deppmann Monday Morning Minute. Vacuum condensate transfer pumps exist in many older steam heating systems. There were many reasons contractors and engineers used these pumps but most of the systems fall into three categories: time control, temperature control, and condensate lift.
Our Monday Morning Minute (MMM) in September outlined the value and need of using Bell and Gossett triple duty valves in variable speed pumping applications. The use of the triple duty valve ports will make it easier to determine the maximum speed to set in the drive.

R. L. Deppmann is offering another series of seminars, this fall, which are centered on “Energy Savings and ASHRAE 90.1 and 189.1 standards”. During a couple of the first 7 seminars, the question of the air separation location sparked a short discussion. Let’s review the response in this Monday Morning Minute.
Every week a question comes in to R. L. Deppmann about the minimum flow rate through pumps. In hydronic heating and cooling systems, it is …
Bell and Gossett triple duty valves have, for decades, provided a cost effective way to assure there is a non slam check, balance, and shutoff valve on the discharge of your hydronic pump installation. These valves are used to throttle excess head and, therefore, should not be oversized. B&G offers these installation friendly valves in traditional full port model (3DS-S) and in a reduced port version (3DS-B)
The RBT-3000 is a combination safety and energy saving device for installation on hot water heating boilers. The low water cut-off turns off the burner when an unsafe water loss occurs in the system. The energy saving feature reduces fuel consumption, wear on boiler parts and burner emissions. The control actively manages the burner cycling along with the operating control to match boiler output to the required load.
In today’s economy there are many small office, retail, and tenant fit-out work jobs than large expansive projects. These smaller projects come with tighter budgets. Here is a tool you may not be aware exists. Bell and Gossett ECO-CIRC under sink recirculating pump available for tank type water heater as well as tank-less systems. High efficiency and lead free brass construction.
