Tips on Purchasing a New Heating System
All heating systems must be properly sized for your house – be wary of the contractor that says one size fits all because this is not true.
You should also be skeptical if a contractor simply looks at your old system and proposes a system of the same size. Changes in your home over the years can lead to it requiring a larger or smaller system. Plus, your home may not have been properly sized at the start. A system that is too big or too small will lead to problems, higher fuel bills and the premature failure. Proper sizing is the most important element when selecting a new heating system for your home.
A qualified heating contractor should perform a heat loss on your home to determine how much heat is required to heat your home comfortably on the coldest day of the year. This should be used as the upper sizing limit, as installing too large of a heating system is not good for a home; it will only waste energy and break down more frequently, shortening the life of the system.
Proper Steps to Size a System
Many factors should be considered in sizing the proper heating system for your home. Key factors include the following:
- The local climate
- Fuel types available
- Size, shape, and orientation of the house
- Insulation levels
- Windows(location, area and type)
- Air infiltration rates
- The number and ages of occupants
- Desired comfort levels wanted by the occupants
- The types and efficiencies of lights and major home appliances that give off heat.
These factors affect a home’s heating requirement, or “load.” Your contractor should measure walls, ceilings, floor space, and windows to determine the room volumes, and should assess the R-value of the home’s insulation, windows, and building materials. An estimate of the building’s air leakage should be conducted; using a blower door test is the best way to measure air leakage.
When designing your new heating system, the contractor you choose should do the following:
- Use a computer program or written calculation procedure to size the system
- Provide a written contract listing the main points of your installation and include the results of the load calculation
- Give you a written warranty on equipment and workmanship
- Allow you to hold the final payment until you are satisfied with the new system.
