Heat Transfer Calculator. To approximate the results of a heat transfer system; enter the fluid data and enter 5 of the 6 available inputs under Flow Rates and Temperatures. A box will be highlighted yellow if it needs input. The currently calculating value will always be highlighted in green. ### Calculate How Many BTUs are Needed to Heat Home - Inch

However, if a furnace is rated at 100,000 BTUs and is 92% efficient, then the heat output will be 92,000 BTUs (100,000 × .92). It may be worth considering a more efficient furnace as less energy will be used to achieve the same heat output. Use a Smart Thermostat. Smart thermostats can also improve the efficiency of your heating and cooling system. ### Heating BTU Calculator & Heaters by BTU

Heating BTU Calculator When shopping for heaters, many people make the mistake of choosing the wrong size for their actual needs. Given all the different options available for heaters –– space, vented, gas, console, and more –– narrowing down the choices can be a great way to ensure that you are choosing the best option. ### BTU Calculator

It is approximately the energy needed to heat one pound of water by 1 degree Fahrenheit. 1 BTU = 1,055 joules, 252 calories, 0.293 watt-hour or the energy released by burning one match. 1 watt is approximately 3.412 BTU per hour.

Energy balance calculation for heat exchanger. Energy balance calculation is often done for designing a heat exchanger to determine operating parameters for hot and cold fluids such as - inlet / outlet temperatures and flow rates. Heat lost by the hot fluid = -Q = m H × Cp H × (To H - Ti H) …. (1) Heat gained by the cold side = Q = m C × Cp C × (To C - Ti C) …. ### Water Heating Calculator for Time, Energy, and Power

The calculators use the specific heat capacity of water of 4186 J/kg/°C (Joules per kilogram per degree Celsius). The heat capacity is largely constant in the temperature range that the calculators work (34-210°F or 1-99°C). It is the way it is taught at school. For practical purposes, it should be precise enough. ### Heating Calculator - BTU Calculator - PlumbNation
