Water Heating Calculator for Time, Energy, and Power

Mar 13, 2016 · Lets make a calculation example for a tub with 250 us gallons that cools down from 105f to 103f in 2 hours. Using the Water Heating Power Calculator above (250 us gallons, start temperature 103f, end temperature 105f, 120min) tells us that a heating power of 611 watts is required.

How to calculate the kW required to heat a volume of water

Sep 26, 2012 · Also we can use this information to extrapolate both ways. To heat the same water volume in half the time (30 minutes) would need twice the heating power, ie, 7kW. Converesely, if we only use half the heating power, 1.75kW, it will take twice as long to heat up to desired temperature, ie, 2

Jul 03, 2012 · 1 Ton = 25 Million (app.) ELECTRICITY. 1 KW = 3,412 VOLTAGE x 1.732 VOLTAGE x 1.732 WATER HEATING FORMULAS . BTU Per Hour Requirement. BTU OUTPUT = GPM x Temperature Rise x 8.33 Lbs/Gallon x 60 Minutes % of Hot Water Required = (Mixed Water ºF Cold Water ºF) (Hot Water ºF Cold Water ºF)

Approximately 9.810657 x 10 3. A boiler horsepower is more than 13 times larger than mechanical horsepower (~engine output). 1 BTU (International Table) per Hour: Approximately 0.293 071 Watts (SI).

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

Boiler Water Tests | Viking Water Technology, Inc.

May 04, 2016 · For practical purposes, 1 ppm = 1 mg/l and 1 gpg = 17.1 ppm. The term ppm is unitless; that is, as long as the same units are used on both sides of the relationship, any units can be used. For example, 1 ppm can be used to express all of the following; one ounce per million ounces, one pound per million pounds or one ton per million tons.

How to calculate the gas consumption of the gas boilers

Boiler horsepower (BHP) is an obsolete non-metric measurement unit of power. Nevertheless, BHP is still used to measure boiler output in industrial boiler engineering in North America. One Boiler Horsepower (1BHP) is equal to a bolier thermal output of 33 475 BTU/h (British Thermal Units per Hour) or 9.81055407 kW (Kilowatts).
