Heating Systems

For ideal pig house temperatures

Ideal house temperatures have a substantial influence on pig health and performance. Adequate heating systems are therefore required in many climate zones. The overall goal is to maximize the thermal yield and transfer it to the pigs in the best possible way to keep energy costs as low as possible.

Big Dutchman offers several different systems to fit your needs:

Hot Water Convection Heaters
Delta Pipe and Twin Pipe
Fin Heater
Zone Heating
Two-climate System
The 235pro climate computer ensures consistent temperatures

Hot Water Convection Heaters

No open combustion inside the house

Convection heaters are becoming increasingly popular, since they significantly improve the house climate (reduced CO2 concentration int he house air). The objective is to maximize the heat output. This is achieved by a radiator with a large surface. The heating elements are mounted directly beneath the air inlets to heat the incoming air.

In piglet rearing houses with two-climate systems, mainly twin pipes are installed directly in the resting area. This saves energy costs as temperatures in the rest of the pen can be significantly lower.

The 135pro and 235pro climate computers regulate the entire house climate, including the continuous three-way control of the hot-water heaters from 0 to 100%. The pigs do not have to suffer from temperatures fluctuating which benefits them and maximizes their growth.

Delta Pipe and Twin Pipe

Ideally suited for diffuse fresh air systems

Delta and Twin pipes are especially well-suited for ceilings with spray-cooling channels and DiffAir ceilings. They are made of aluminum and are operated with hot water, of which they require only a limited amount, however. Thanks to their good thermal conductivity (heat output of 180-200 watts/m) the ensure constant room temperatures inside the house. These heating systems can also be used as pre-heating in the central aisle. The pipes have an anodic coating for a better protection against ammonia. They are of comparatively low weight and can be delivered in different sizes up to a length of 6m. The pipes are easy to assemble.

Delta pipe – ideal for installation below the DiffAir ceiling
Twin pipe – less dust on pipes
Fin heater as a full-space heating system- ideal in combination with ceiling inlets
Galvanized fin heater
Special coupling for time-saving assembly

Fin Heater

Large surface area for high heat output

The fin heater consists of a galvanized tube or of an aluminum tube with epoxy powder coating through which hot water is pumped. Fins are welded to the tube like a spiral, creating a large surface of 1m2/running meter of tube. Heat emerges from these fins and causes a strong thermal. The heat output can be as high as 600 watts/ running meter. The spacing between the fins is large enough to ensure that dust does not accumulate. The tubes are fastened to the wall by means of angle brackets or suspended from the ceiling, which is very easy to carry out. An automatic ventilation (for Delta and Twin pipes as well) ensures a high functional reliability of the heating system.

The aluminum fin heater is characterized by the following advantages:

  • Reduced Weight
  • Increased heat output, up to 750 watts/running meter
  • Simple, time-saving assembly by means of special coupling with clamps

Zone Heating

Ideal for use in piglet rearing houses

Piglets need a lot of warmth, especially during the first days after moving to the rearing house so as to be able to cope better with the critical weaning period. Ideally the resting area should have a temperature of approximately 32°C. Apart from traditional full-space heating, zone heating operated with hot water is becoming increasingly popular for pig rearing houses. Such zones are created using a covering plate or hover that is fixed at a distance of 70 to 80 cm above the slatted floor. The required dimensions of the cover depend on the number of piglets and the depths of the pen. An edge of approximately 20cm in the front area of the plate helps to create a heat blanket. The heating system (Twin pipe) is installed directly below the plate. The main purpose of this system is to heat the resting area of the piglets. As the rest of the pen does not require as much heat, therefore making lower temperatures possible, heating costs are significantly reduced.

Plastic flooring with only 10% slatted area is used beneath the covering plate; Twin pipes ensure optimum temperatures in the piglets’ resting area

Two-climate System

We recommend connecting the set temperature values of full space and zone heating as a result the heat requirements of the pigs can be met in an ideal manner, keeping pace with their age. The illustration shows DiffAir ceiling in combination with Delta pipes to heat the incoming air (full space heating), and a zone heating system to provide the required higher temperature in the piglets’ nesting area. The 135pro and 235pro climate computers control both full-space and zone heating.
