According to Alliant Energy, a Midwest energy delivery company, the general rule of thumb holds that indoor spaces require one boiler horsepower of energy per 1000 square feet of space. Remember that one BHP equals 33,475 British thermal units. Therefore, dividing this by 1000, this general rule requires 33.475 BTUs of power output per square foot.

5/9/2016 · Before you get the chance to attend a class, here are ten simple rules of thumb for designing hydronic systems: PSI x 2.31 = feet of head (TDH) GPM x Delta T x 500 = BTU/hour. Pressure Drop for piping system = Linear Feet of Longest Circuit x .06. Proper flow for boiler in GPM = Output BTU/hr. divided by 10,000.

19/12/2020 · In reality, the boiler size rule of thumb is the more radiators you have, the higher output rating you need with A++ being the best that is currently on the market. So if you're looking to find out the answer to "what size boiler do I need for 16 radiatiors?", then the answer is one with the best possible rating that you can find.

28/3/2016 · Boiler feed units are generally sized for 5 minutes of net storage. You can feed your boiler for 5 to 10 minutes, depending on the load, to keep it steaming while waiting for condensate to come back. In smaller systems, up to 150,000 sq ft EDR, 5-minute pumping capacity is a good rule of thumb. For systems larger than 150,000 sq ft EDR, 10

Another quick rule of thumb is that 1/10 of a gallon is needed for every boiler horsepower. So a 500 HP boiler will need a pump capable of delivering 50 gpm. An 800 HP boiler will need an 80 gpm pump. The next step is to determine the proper discharge of the pump.
