Heat pump, the new surprisingly old way to heat a greenhouse.

Updated: Jun 19, 2023

With the increasing trend of environmentally friendly efforts, heat pumps have successfully replaced old oil-fired boilers. The air energy heat pumps are now used in various fields as a part of energy conservation and emission reduction policies.

Now, not only thousands of households but agricultural specialists also do heat pump greenhouse heating to get effective results.

So, what is a heat pump, and how can you use it to enhance your vegetation experience? Let's find out.

What Is a Heat Pump?

A heat pump is a device that helps greenhouse growers transform low-temperature energy into higher-temperature energy, just like your refrigerator. This technology has been around for more than a century now.

It is believed that ground-source heating systems save up to four times more energy than oil or gas boilers. This is because these devices move naturally-available energy rather than producing emissions that lead to global warming.

Types of Heat Pumps

There are four types of pumps for environmentally-friendly greenhouse heating:

  • Ground Source Heat Pumps. These draw the heat energy from the Earth to your greenhouse.

  • Air Source Heat Pumps. These are the ideal pumps for greenhouse growers, providing a versatile system that efficiently heats and cools the greenhouse.

  • Water Source Heat Pumps. These pumps draw heat from the water and transform it into heat for your greenhouse.

  • Heating & Cooling Systems. These all-in-one pumping systems serve as an air-conditioner, a boiler, and a radiator to offer underfloor heating and fan coil services.

Is an Air Source Heat Pump the Ideal Choice for a Greenhouse?

An air-source heat pump absorbs heat from the outside environment and releases it into the greenhouse's interior. These devices are of two types depending on their functions:

  • Air-to-Air Systems. They deliver warm air that heats the entire greenhouse.

  • Air-to-Water Systems. They heat water that provides both heating and hot water for the greenhouse through radiators or an underfloor heating system.

The Energy Saving Trust in the UK found that air-source heat pumps can reduce heating bills by £870 annually and carbon dioxide production by 6 tonnes.

How Does Air Source Heatpump Greenhouse Heating Work?

The heat pump has three parts that ensure adequate heating to your greenhouse, including:

  • Evaporator Coil. It draws heat from the outside.

  • Compressor. It then pumps a refrigerant type with the heat pump and compresses the gaseous form to the ideal temperature for heat distribution.

  • Heat Exchanger. This part then transfers the heat energy obtained from the refrigerant to air or water.

The air-to-air and air-to-water systems then transfer this heat to the greenhouse for effective and energy-sufficient vegetation.

When comparing your alternatives, don't forget to factor in the following.

  • Cost of energy

  • Cost of installation

  • Cost of maintenance
