Warehouses – how to heat them effectively?

Warehouse buildings are objects of a large cubic capacity, which require the use of an appropriate heating system. Radiators and surface heating definitely will not work here. It is difficult for this type of system to operate effectively when an enormous space must be heated.

The basic challenge – maintaining the right temperature

Work of people, and often also specific requirements of stored goods, impose on owners of warehouse spaces the necessity to maintain the temperature at a certain level. The system should be able to react dynamically to its drop – a long wait for heat from radiators is a discomfort primarily for employees, but also a problem in the storage of sensitive products. Traditional heating most likely does not meet this requirement.

Which system will be right?

The best solution in this type of buildings are various types of air heaters. They can be independent heating devices or part of a central heating system. The former are usually supplied with gas or fuel oil. You should then ensure safe fuel supply and exhaust removal. It is a solution worth considering for warehouses that do not have a central heat source, e.g. a boiler, a heat distribution centre or a heat pump. However, if this type of system is in or near the building (for example, there are offices next to it), it is worth considering installation of water heaters.

Air heaters allow for quick delivery of heat to selected room zones. In high buildings, they give a chance to limit the flow of the hot air upwards. If the heaters themselves are not enough for this purpose – you can optionally use destratifiers.

Air heaters and more

A good supplement to the air heaters will be air curtains mounted near gates and doors. These devices constitute a kind of barrier that protects the building against the inflow of outside air and helps to reduce heat losses. In the case of warehouses where the exchange of goods takes place frequently, it is worth considering their use. In addition, the stream produced by the curtain hinders access of insects to the interior.

An alternative when it comes to heating warehouses can be infrared heaters. They heat directly objects in the warehouse (including people), bypassing the air. They are characterised by low inertia and high efficiency. The disadvantage, however, is the power supply – electricity. Electric heating is expensive.

Saving is possible

When designing warehouse heating, it is worth taking into account the latest technical solutions. They allow you to save heat, because they ensure high efficiency of heat exchange, as well as reduce the demand for electricity in the case of devices using, for example, fans. A good example here is sonnEC heaters offered by Neutec with multi-row heat exchangers and EC fans. Their advantages and wide application possibilities can be found in other articles on our blog.
