Natural Refrigerant

​

The SANCOâ‚‚ is the most environmentally friendly HPWH on the market!

In an effort to protect the Ozone layer and as part of the 2006 Montreal Protocol, all refrigerants are required to have a zero Ozone Depletion Potential (ODP). More recently, focus has turned to the Global Warming Potential (GWP) of refrigerants.  The GWP is a standardized metric of how much a given pollutant contributes to Global Warming.
 

The GWP of a gas refers to the total contribution to global warming resulting from the emission of one unit of that Gas relative to one unit of the reference gas (COâ‚‚) - which is assigned a value of 1. GWP is typically measured as the impact of that Greenhouse Gas over a period of 100 Years.

 

Many States and Provinces, such as California, are now scrutinizing refrigerants' GWP and requiring the use of low GWP refrigerants (typically those with a GWP below 750).

 

R134a (seen above) is the refrigerant most commonly used in Heat Pump Water Heaters (HPWH) and has a 100-year GWP of 1,430, well above the recommended threshold of 750.

✘  R134a

  • A single HPWH typically contains approx. 22oz (1.375lbs) of R134a.

  • 1lb of R134a has a 100-year GWP of 1,430.

  • Therefore, the refrigerant in a single HPWH has the potential for a contribution to Global Warming of 1,966.25 times an equivalent quantity of COâ‚‚ over a 100-year period.

This represents a saving in Greenhouse Gas Emissions of 1,964.8.  By using the EPA (Environmental Protection Agency) online calculator at:


https://www.epa.gov/energy/greenhouse-gas-equivalencies-calculator


we see that this is equivalent to the greenhouse gas emissions produced by burning 100 gallons of gasoline or charging 113,000 smartphones.


The SANCOâ‚‚ truly is the most environmentally friendly HPWH on the market!

✔  R744 (COâ‚‚)

  • A SANCOâ‚‚ unit contains 22.9oz (1.43lbs) of COâ‚‚.

  • 1lb of COâ‚‚ has a 100-year GWP of 1.

  • Therefore, the COâ‚‚ refrigerant in a SANCOâ‚‚ unit has the potential for a contribution to Global Warming of 1.43 over the same period.

The SANCOâ‚‚ HPWH uses the environmentally friendly COâ‚‚ refrigerant, also known as R744.
