Do greenhouses emit radiation?

Yes, greenhouses emit radiation. Plants and soil absorb heat energy and release it as infrared radiation. The greenhouse glass absorbs this infrared radiation and re-emits some of it back into the greenhouse, maintaining a warm temperature even if it’s colder outside.

1. Greenhouses primarily emit infrared radiation.
2. Infrared radiation plays a key role in keeping greenhouses warm.
3. The greenhouse effect is essential for plant growth in greenhouses.
4. The emitted radiation can affect the overall temperature regulation inside the greenhouse.

How much warmer is a greenhouse than the outside air?


A greenhouse is typically warmer than the outside air due to its design, such as sunlight being trapped inside. In winter, you can further decrease heat loss by adding insulation. A practical way is to use bubble wrap polythene, cut to fit and attached on the greenhouse’s interior close to the glass, serving as an effective method to maintain warmth.

What kind of heater can I use in my greenhouse?

For a greenhouse, the type of heater to use depends on factors like its size, insulation, and the outside temperature. Typically, greenhouse temperatures can be about 30°F warmer than the external environment. Factors influencing the choice of heater include the type of crops being grown and the specific temperature requirements for optimal growth. Some common types of heaters used in greenhouses include gas heaters, electric heaters, and propane heaters.

Can a candle heat a greenhouse?

Yes, a candle can provide some heat in a greenhouse. However, to effectively protect your plants from winter weather while being mindful of energy costs and the environment, consider these tips:
1. Place candles strategically to distribute heat.
2. Use multiple candles for better warmth.
3. Monitor candle usage to ensure safety.
4. Consider alternative heating methods like electric heaters for more consistent and controlled heat.

What is the best heat sink for a greenhouse?

The best heat sink for a greenhouse is tubular heaters. They are more cost-effective than traditional options like hydronic heaters and fan heaters. Unlike boiler heaters that need a lot of water, pricey piping, and specialized installation, tubular heaters are simple to set up, requiring only a few components for operation.

Additional information:
1. Tubular heaters provide consistent warmth and distribute heat evenly in the greenhouse.
2. They are energy-efficient and offer reliable temperature control.
3. Tubular heaters are easy to install and maintain, making them a popular choice for greenhouse heating.

Will hot water heat a greenhouse?

Yes, hot water can heat a greenhouse. Plastic bottles can work as a heat sink by acting as natural heat absorbents when filled with water and painted black. Placing several black-painted plastic bottles around the greenhouse allows them to gather solar energy during the day and release it back into the greenhouse, effectively heating the space.

Will a candle heat a greenhouse?

A candle will not effectively heat a greenhouse. Propane gas greenhouse heaters, fueled by propane bottles, offer a more practical solution. These heaters are equipped with thermostatic controls and provide cost-effective heating. However, the cost savings compared to electricity are minimal in the current market. Other viable options for heating a greenhouse include: 1. Electric greenhouse heaters 2. Wood-burning stoves 3. Solar-powered heaters 4. Geothermal heating systems.

Are greenhouse paraffin heaters any good?

Paraffin heaters may not be the best option for all plants in a greenhouse. It is essential to consider that some plants may be sensitive to the increased carbon dioxide levels and emissions released by paraffin heaters, such as carbon monoxide, nitrogen oxides, and sulphur dioxide.

1. Not all plants can tolerate the raised CO2 levels and fumes emitted by paraffin heaters.
2. Sensitivity to emissions like carbon monoxide, nitrogen oxides, and sulphur dioxide varies among plant species.
3. Consider using other heating alternatives to ensure the health of all plants in the greenhouse.

What is the cheapest form of heat?


The cheapest form of heat is propane heaters. Propane heaters offer an affordable heating solution for those seeking cost-effective warmth.

1. Propane is generally cheaper than electric heating alternatives.
2. Propane heaters are efficient in heating small to medium-sized spaces.
3. They provide a reliable heat source during power outages.
4. Propane is readily available and easy to store for future use.

What is the most economical heater for a greenhouse?

The most economical heater for a greenhouse is dependent on the power source available. For a greenhouse without mains power, paraffin heaters are cost-effective if fuel is inexpensive. Alternatively, propane gas heaters are a good choice. If electricity is accessible, a thermostatically controlled fan heater is typically the most efficient option for heating a greenhouse effectively.

How do you keep heat in a greenhouse overnight?

To keep heat in a greenhouse overnight, you can reduce heat-loss by installing winter insulation over glazed areas. The most effective method is to use bubble wrap polythene, cut to size and fixed on the inside of the greenhouse, close to the glass.

1. Securely seal any gaps or cracks in the greenhouse structure to prevent heat from escaping.
2. Use thermal mass such as water containers to absorb and radiate heat during the night.
