Traditionally, greenhouses can be quite energy and water intensive, running on fossil fuels which are detrimental to the environment. This is why more and more UK homeowners and gardening enthusiasts are designing their greenhouses with sustainability in mind. In this article, we’ll talk you through the different areas where you can consider improving the sustainability of your greenhouse and how these could benefit you – so that you can garden with a green conscience as well as a green thumb.
Greenhouses are partially heated by the sun (passive solar heat), however, when it comes to winters in the UK, you will require an alternative heat source to keep your greenhouse ticking over.
In more traditional greenhouses, a gas or paraffin heater may be used as an additional heat source. These both require fossil fuels and are damaging to the environment. Gas heaters are also typically bulky and heavy, while paraffin heaters are easy to knock over and are a potential fire hazard. However, there are renewable alternatives, which are not only better for the environment but also for your energy bills.
A thermostatically controlled electric fan heater is one of the best options for heating your greenhouse. This is because it doesn’t emit water, soot, or carbon monoxide, which can all negatively impact your plants. However, for it to be truly sustainable and save you money, you need to ensure that the electricity is coming from a renewable source such as solar panels. If you combine this with a solar battery, then you’re better able to save and harness the sun’s energy whenever you need it.
Another sustainable option for heating your greenhouse is an air source heat pump. Heat pumps usually have high efficiency ratings of 300-400%,
