Best Electric Heater For Greenhouse

10 Best Electric Heater For Greenhouse 2022 – Reviews & Guide

Choosing the best electric greenhouse heater for your operation is a big decision, and you definitely want to do it right. When considering electric heaters for greenhouses, you want to make sure that the unit provides adequate heating to keep the plants happy without compromising on energy efficiency.

The most important factor in choosing an electric greenhouse heater is the design of your greenhouse. If it has a rigid structure with no holes or vents for cross ventilation, then you will need to go with a more powerful and larger unit that will provide more heat.

However, if the structure of your greenhouse is not very rigid then you can get away with a smaller unit that uses less power. If your greenhouse is a good size and there are enough vents or holes to allow cross ventilation, then you can consider a smaller and cheaper model.

When shopping around for an electric greenhouse heater, look at both the wattage rating and the BTU rating of the units available. You can easily calculate one from the other by dividing the wattage rating by 1,000 and multiplying that number by the BTU rating.
