What is the principle job of just about any residential or commercial heating system? Is it to "heat up" a residential or commercial structure? No, typically the primary job it to gently and evenly replace the heat energy that is lost by a structure. There are exceptions to the above statement - do you know what the exceptions are?
For years, we have had the technology that enables us to accurately determine how and where heat energy is lost. Unfortunately, there is a substantial amount of math and science involved with this technology and many heating mechanics (who call themselves "contractors") never made the commitment to thoroughly understand the science of heat loss.
A heating system will not perform correctly if it is not properly sized. An improperly sized system will often cause one room is too warm while another room feels chilly. A heating system that is oversized will raise the temperature of a structure (or zone) too quickly, overshooting the desired temperature set-point. In addition to the comfort issue, the department of energy has demonstrated that over sizing a heating system waists energy. Did you know that most heating systems over 25 years old are oversized?
Did you know that a HVAC businesses is liable for the systems it designs. A home owner, or a general contractor is relying on you to be an expert in the HVAC field. If you fail to properly size a heating system, you could be (and in the opinion of the Furnaceman - "should be") subject to a law suite.
If you are using "rules of thumb", or some cardboard calculator, or relying on a canned software package to determine heat loss, you need to take our course. Students who successfully complete this course will understand heat loss inside and out. They will able to calculate "on the fly" the various losses that affect a structure. A person knowing this subject mater will be able to identify mistakes made by others. That person will be in a position to capitalize on the lack of knowledge of others.
This is not an easy course, and it requires a solid understanding of math, including basic algebra. For those who successfully complete this course - they will be in a position to design superior heating systems for their customers.
The residential heat loss course runs for a minimum of 24 hours, and can be scheduled evenings, or days. Class size ranges from 10 to 20 students. Students must have a calculator for class.
