Powerful heater in a compact package
a year ago
This very compact heater outperforms much more expensive units in keeping my greenhouse above freezing even when temps outside dip below zero. It does make noise, as pointed out by some of the less positive reviews, but in my space this is not an issue, being able to heat is what I need from this heater and it delivers!
