The Propane Education & Research Council is partnering with heater manufacturer L.B. White to study the benefits of using variable-rate controls on propane-powered heating systems in livestock buildings. "The partnership with PERC is allowing L.B. White to accelerate the demonstration of improved fuel savings, presently documented as 15[%] to 35%. And more importantly, it allows us to document the improvement in animal productivity and health with dedicated trials that are starting shortly," said L.B. White Engineering Director John Tomlinson.
