WATER HEATER SIZING GUIDE FOR ENGINEERS

Boiler Sizing Calculators | Powerhouse

To do so, we divide the BTU/hour by a constant of 33,475. This constant represents water being converted to steam, which is 34.5 pounds of water multiplied by 970.3 BTU/lb, or latent energy. For this calculation, you will enter the BTU/hr of your operation along with the efficiency of your boiler.

Select water heating equipment for a 200-room convention-type motel. The flow rate of each shower head will be 2 GPM. The laundry will have three 50-lb washers. There will be no food service. The owners request one central system. First, calculate the rooms load: RD = TU x FR x AF x 0.8 RD = 200 x 2 x 5 x 0.8 RD = 1600 SR = RD x .33 SR = 528

The key to proper water heating system design is to correctly identify the quantity, temperature and time characteristics of the hot water requirement. The goal is to reduce hot water wait time to 10 seconds or less, which is considered acceptable for public lavatories. A wait time of 11 to 30 seconds is considered borderline and a wait time of 30
