Types of System

for Different Climate Zones

Go to City-Data.com's Average Temperature Chart for your city or area. You can determine if you need to order a Tropical, Temperate or Freeze system using these charts. Over 90% of the US is a hard freeze area.

If you are in an area that may be Temperate, go to your city or area and look at the lowest average temperature, then go 20 degrees lower. If it is below 30 F, you are in a "Cusp" area and may need a hard freeze system unless you are willing to drain and blow your systems collectors clear of water if a freeze is expected.

If Average Daily Low Temperature minus 30 degrees is less that 30 F, be aware that you are still in a marginal zone. This means you will probably be OK with the Temperate system but may be subject to freeze damage in your coldest weather, which may occur over 10 years or so. Some Temperate areas are more or less subject to wide swings in "Coldest" temperatures, so check your local weather data history if in question.
