9 tips to save energy
Energy is one of the biggest costs for many growers. Nevertheless, some horticultural businesses still waste a relatively large amount of energy, for example due to a lack of maintenance of the boiler, insufficient insulation and air leaks. In this article we will give 9 tips on how to save energy. These tips do not require a large investment, but can lead to considerable savings.
1. Maintenance of the heating system
If a heating system is not maintained properly, this can lead to corrosion, lime scale and blockages.
A result could be an increase of the energy cost because the heating system has to work extra hard to maintain het greenhouse temperature. That is why it is important to maintain the heating system properly and have it inspected annually.

2. Check the insulation of pipes
In a well-insulated boiler room for a greenhouse should be between 12 and 15⁰C all year round. If the boiler room is warmer than 15⁰C it means the system is losing heat from the heating system. The generated heat must be transported to the greenhouse
and not delivered to the boiler room! Therefore, it makes sense to carry out periodic spot checks on the insulation of the pipes (don't forget the bends!). On a well-insulated pipe through which water from 80 to 90⁰C flows, you should be able to lay your
hand without burning.
4. Switch off a stationary boiler
If you are using multiple energy sources and the boiler is actually on stand-by for most of the year, check how often the boiler is still running for a short time and why. You can consider turning the boiler off completely for part of the year. Make sure
that you open both the front and the hatch at the back of the boiler to prevent the risk of condensation forming during standstill.
7. Insulate around the greenhouse soil
Avoid leaking energy from the warm greenhouse soil indoors to the cold(er) soil outside. To do this, place PUR or tempex plates 3 to 5 cm thick along the base of the greenhouse, half a metre buried. PUR has the advantage that it has a closed cell structure
and therefore does not absorb or permeate water.
8. Place insulation plates behind the heating pipes
If you are growing on cultivation gutters, place PUR, tempex or other insulation boards with a reflective layer behind the heating pipes to keep the heat inside the greenhouse. Place the panels on the base of the greenhouse against the front and side
wall glass to a height where it has no adverse effects on the crop (such as shade).
9. Painting the heating pipes
You can also save energy by painting the heating pipe in the greenhouse white. A white heating tube reflects up to 50% more light and provides up to 20% more heat output. By painting the heating tubes you reduce the heating costs. Would you like to know more about having your heating installation painted? Agro Active provides these services.
