Holland Heaters
Energy efficient Greenhouse Heaters
The levels of CO during combustion are extremely low.
CO( Carbon Monoxide) levels are less than 10 PPM(parts per million)
Conventional greenhouse heaters have levels around 90 PPM.
In addition to the clean burning we always use outside air for combustion. The fresh air intake unit is always bringing in outside air. The heater will not use air from inside the greenhouse for the burning process.
Listed below is a statement from CSA of the testing results during the certification process.
What is CSA?
-Canadian Standards Association
Great reasons to trust CSA marks
When you see the CSA mark, do what millions of others do every day-proceed
with confidence! Here's why:
CSA is a North American leader in product testing and certification, with a respected history dating back to 1919.
CSA International is accredited in the U.S. by the Occupational Safety and Health Administration (OSHA) as a Nationally Recognized Testing Laboratory (NRTL), and in Canada by the Standards Council of Canada (SCC).
CSA works closely with the International Association of Electrical Inspectors (IAEI), the Electrical Safety Foundation International (ESFI), Health Canada, provincial regulators, and the U.S. Consumer Product Safety Commission (CPSC) to promote standards for consumer safety in North America and around the world.
The CSA marks mean a product has been tested and meets applicable standards for safety and/or performance, including the applicable standards written or administered by the American National Standards Institute (ANSI), Underwriters Laboratories (UL), Canadian Standards Association (CSA), National Sanitation Foundation International (NSF), and others.
CSA field representatives conduct more than 50,000 factory visits each year, worldwide, to ensure that CSA-certified products continue to meet the applicable standards.
CSA marks are accepted by inspectors in the electrical, gas, building, and plumbing fields in the U.S. and Canada.
The CSA Mark appears on over one billion products worldwide. We test and certify electrical components and products, gas-fired appliances, plumbing products, personal protective equipment, and many more products to applicable U.S. and Canadian standards.
