Calculating Greenhouse Heating Cost
Knowing how much it costs to heat a greenhouse is key for planning and budgeting. You need to think about the size of the greenhouse, how efficient the heating system is, and the local energy prices. By looking at these factors, owners can figure out the total heating cost. This helps them plan their energy use better.
First, find out the heat loss value of the greenhouse covering material. This is called the U-value and shows how fast heat moves through the material. The lower the U-value, the better the material is at keeping heat in. Common materials and their U-values are: 4 mil polyethylene (1.20), 4 mm twinwall polycarbonate (0.70), and 6 mm twinwall polycarbonate (0.62).
After finding the heat loss value, estimate how much heat the greenhouse needs. This depends on its size and the temperature difference inside and outside. For instance, an A-frame greenhouse at 66.6°F with outside at 30°F needs 135,878 BTU/hr. A Quonset greenhouse requires 170,860 BTU/hr for the same conditions.
| Greenhouse Model | Size | Heating Requirement (BTU/hr) | Daily Heating Cost at $0.12/kWh |
|---|---|---|---|
| A-frame | – | 135,878 | $89.60 |
| Quonset | – | 170,860 | $112.65 |
To find the total heating cost, change the heating need to the fuel type you use, like kilowatt-hours of electricity or gallons of propane. Also, remember to use the local energy rates to figure out the daily or monthly costs.
By using this detailed method, greenhouse owners can get a clear idea of their heating costs. This helps them use energy wisely and cut down on their expenses.
