Heating the Greenhouse 

Heating the greenhouse is certainly a huge task when subfreezing temperature exist.  Heating with a wood stove might not be worth the expense.  A waste oil heater is a more economical choice.  This heater is designed for a permanent greenhouse structure.   When there is severe weather and heavy snow, a permanent and solid greenhouse is required.  A simple wood shed with double pane ceiling windows is a perfect way to get a jumpstart on the season.  

This heater is not recommended for use in a small area greenhouse or in a plastic sheeting greenhouse.  Note:  The greenhouses posted on The Pond Plant Girl Show are designed as temporary structures and are not built for oil heaters or for severe cold climate zones. Excessive heat can spark a fire.  This is an important consideration when it comes to home insurance quotes.  If constructed and installed in a small area, I recommend a concrete, dirt, or brick  floor.  Aluminum siding should also be installed on the walls adjacent to the oil heater and possibly on the ceiling to prevent fire danger.
