Heating

Energy-efficient installations

In climates that need heating, choosing the right installation is not always easy. Not in the least because energy will become even more expensive in the future. How do you choose the right system for your local conditions and your growing needs whilst keeping cost to a minimum? Let AP Holland answer that question for you. Designing and engineering heating systems is what we do – all day, every day.

We use a wide range of technical solutions to create installations that consume as little energy as possible. Gas boilers in every size imaginable, combined with reliable burners, guarantee continuity. We also factor in integration with CO₂ dosing to ensure the optimal growth of your crop. And, of course, we also take low maintenance costs into account when developing your installation.

Alternative energy sources

It is becoming increasingly popular to use natural heat and cold from the ground. AP Holland is an experienced partner in geothermal projects, in which several greenhouse horticulture companies use the same sources.

Cogeneration (combined heat power, CHP) is an efficient option in many situations, as is using residual heat (or CO₂) from industry.

Here at AP Holland, we are more than happy to point you in the right direction.

Boiler room

The boiler room is the heart of the heating installation. For AP Holland the boiler room is an innovative technical space: industrial and modern in design, made to meet the exact heating requirements of your crop.

By installing a condenser at the same time, you can use the released CO₂ when producing heat to stimulate growth in the greenhouse.

Greenhouse heating

Heat is transported to the greenhouse through pumps and pipes based on the Tichelmann system. Tube rail heating is the most commonly used heating system. This is particularly practical because the rails can simultaneously function as an internal transport system in the greenhouse.

It is also possible to install a pipe system above the crop if heat also needs to be distributed from above. This monorail heating system can also be used for transportation or for carrying out maintenance work above the crop. A snow heating system can also be installed along the roof gutters to melt any snow on the roof.

Heat storage

Do you not need to use the heat produced by the boiler immediately? Heat storage tanks give you the option of producing energy and using it at a later time – giving you maximum flexibility in your energy consumption, at the lowest cost.

AP Holland can build heat storage tanks in any size. These tanks are used to store heat temporarily at a temperature between 65 and 85 °C, which is efficiently regulated by the climate computer.

Dry Cooling

When the maximum capacity of the heat storage tank has been reached, but the heating system continues to produce heat, the excess heat must be destroyed. A dry cooling system can be used for this purpose.

Cogeneration (combined heat power, CHP)

Cogeneration has become more common in greenhouse systems as a result of the ever-increasing gas prices and electricity rates in greenhouse horticulture. Growing crops under artificial light also requires a significant amount of electricity.

The CHP unit produces heat for cultivation as well as electricity for lighting. Any surplus electricity can potentially be fed back to the grid. CO₂ is a by-product of burning natural gas, which can be used to give an extra boost to crop growth.
