The Garage Furnace Size Calculator is a valuable tool used to determine the heating capacity needed for a garage space. It calculates the required British Thermal Units per hour (BTU/hr) based on specific inputs such as the volume of the garage, desired temperature increase, and heat loss factor.

### Formula of Garage Furnace Size Calculator

The calculation formula used by the Garage Furnace Size Calculator is as follows:

`BTU = Volume × Temperature Difference × Heat Loss Factor`

Where:

**BTU**is the required heating capacity in British Thermal Units per hour.**Volume**is the volume of the garage in cubic feet.**Temperature Difference**is the desired temperature increase in degrees Fahrenheit.**Heat Loss Factor**is a factor that considers the insulation level and other factors affecting heat loss. It typically ranges from 1.0 to 2.0, with 1.0 indicating a well-insulated garage and 2.0 indicating a poorly insulated one.

To calculate the volume of the garage, the following formula is used:

`Volume = Length × Width × Height`

### Table of General Terms

Term | Description |
---|---|

BTU | British Thermal Unit, a measure of heat energy |

Cubic Feet | A unit of measurement for volume |

Fahrenheit | A scale for measuring temperature |

Heat Loss Factor | Factor considering insulation and heat loss characteristics |

This table provides definitions for general terms related to the calculation, aiding users in understanding the concepts involved.

### Example of Garage Furnace Size Calculator

Suppose you have a garage with dimensions of 20 feet in length, 15 feet in width, and 10 feet in height. You want to increase the temperature by 30 degrees Fahrenheit, and the insulation of the garage is average, with a heat loss factor of 1.5.

Using the Garage Furnace Size Calculator:

**Calculate Volume**:cssCopy code`Volume = Length × Width × Height = 20 ft × 15 ft × 10 ft = 3000 cubic feet`

**Calculate BTU**:mathematicaCopy code`BTU = Volume × Temperature Difference × Heat Loss Factor = 3000 cubic feet × 30°F × 1.5 = 135,000 BTU/hr`

So, a furnace with a capacity of 135,000 BTU/hr would be suitable for heating this garage.

### Most Common FAQs

**1. How do I determine the volume of my garage?**

To calculate the volume of your garage, multiply its length by its width and then by its height. This will give you the total cubic feet.

**2. What is the heat loss factor, and how do I know what value to use?**

The heat loss factor takes into account the insulation level of your garage and other factors affecting heat loss. It typically ranges from 1.0 to 2.0, with 1.0 representing a well-insulated space and 2.0 representing a poorly insulated one. You can estimate the heat loss factor based on the insulation quality of your garage.
