The Types of Heat Loads

Choosing the right equipment for your home’s heating and air conditioning purposes is an integral part of planning for an energy efficient and money-saving system. Experts often use three types of heating loads when considering a home’s needs, and in this short guide, we’ll give you a brief overview of these concepts.

Loads and Capacities

Effective heating and air conditioning of an entire house often use the terms “load” and “capacity”. Loads refer to the amount of heat a building needs in order to be adequately covered. Capacity, on the other hand, is the maximum amount any device can produce.

Planning for an efficient heating and cooling system requires a careful accounting of a home’s total load and the capacities of the devices to be installed.

Design Load

There are three main types of loads that heating and air conditioning experts often consider, and the first one is called the design load. The design load is the hypothetical amount that any particular home needs. An HVAC engineer can calculate a home or a building’s design load using pre-existing data and a set of protocols laid out in Manual J set by the Air Conditioning Contractors of America (ACCA). The results of these calculations are used as a rough but accurate estimate of your heating needs.

Extreme Load

Extreme loads are the maximum heating and air conditioning levels typically set much higher than the design load. This type of heating load is often used to account for extreme weather variations, such as cold spells and heat waves. Design load calculations often already cover a range 10-15% higher or lower than actual loads to make room for drastic changes in outdoor temperatures. This is why extreme loads are rarely used in load planning.

Part Load

Part loads are more or less the actual load that your home will operate on at any given day. Because you’ll be spending a major part of every season running on part load conditions, experts give careful consideration for this particular type of load.
