Greenhouse Dimensions
The size of your greenhouse is a significant determinant when it comes to deciding the amount of heat you require to warm the vicinity. Luckily, you have an advantage if your greenhouse is insulated, as it helps to retain the warmth. However, a larger space which has no insulation will require more power as compared to a smaller space. Therefore, when it comes to buying, first consider the dimensions then compare it with the power output of the model you want to purchase. Sometimes, more than one heater is necessary when you consider the space.
Determine the source of power
As much as bills are unavoidable, you can still control your expenditure. See below the types of heaters with regard to the source of heat.
1. Paraffin heaters
These models have been in the market for years, and they solely depend on paraffin to power up. They are mostly ideal for keeping away the frost other than maintaining the greenhouse’s
temperature.
Pros of paraffin heaters
These heaters are low maintenance models.
They emit carbon dioxide, which is healthy for the plants.
The models are affordable to purchase as well as maintain.
With these models, you do not have to worry about the loss of electricity to keep them working.
Once you buy the paraffin, you will not have any other expenditure later.
Cons
They require manual tuning off and on.
You need to be present to regulate it; otherwise, the heater will run till the fuel runs out.
The heater produces water that encourages the growth of mould.
2. Electric heaters
These models are highly available in the market. To their advantage, they have thermostats that play an essential role in turning them into energy-saving heaters. All you need to do is set the heater to the temperature you require. Afterwards, the thermostat stops using more electricity until you require it again.
Moreover, they use a water protection medium to work properly. The IPX4/6 feature helps you find out whether the heater is safe from moisture damage. As a result, the unit remains functional whether the moisture is present in the air or not. Mostly, you will find ceramic, radiant, infrared and convection types of electric heaters, among others. Besides, their functionality is highly
dependent on the specific technology used to manufacture them.
The best models are those that come with fans to help in the circulation of hot air. Furthermore, the fans help to rid off the excess moisture that may contribute to the growth of toxic moulds. Most of these models come with a stable posture where you can either leave them standing or hang them in a suitable position. Generally, electric heaters are the best as they are easy to use
and do not require constant powering up. More so, they maintain consistent temperatures in the greenhouse.
3. Propane heaters
These heaters are also affordable, as they power up by using propane which is easily accessible. Their production of carbon dioxide makes them more useful to keep the vegetables and plants in your greenhouse healthy. However, you will have to continually check and change the propane bottles due to the moisture they produce.
The power rating
Since most units measure power outputs in Kilowatts, you will find most models ranging from 1- 3kw. Consequently, these ratings often limit the space that needs heating. High heat productions go hand in hand with larger areas. If your vicinity already has insulation, you will not need high rates of power and vice versa. Most people have small greenhouses; therefore, a unit with at least
a power rate of 2kw is sufficient.
Let’s now have a look at our recommended models to help you in choosing an efficient greenhouse heater.
