Heating systems
The correct indoor temperature has a substantial influence on the health and performance of your pigs. Adequate heating systems are therefore a necessity in many climate zones. The overall goal is to maximise the thermal yield and to transfer it to the pigs in the best possible way to keep energy costs low.
Big Dutchman offers several different heating systems for full-space or zone heating. The heaters can be fuelled by gas, oil or hot water.
JetMaster
JetMaster is a tried and tested heater that has been part of the Big Dutchman product range for many years. JetMaster heaters are available for operation with natural gas or propane as well as fuel oil and are thermostat-controlled. Since the flame is monitored, the gas supply is immediately interrupted should the heater not ignite or the flame extinguish.
The built-in fan propels the warm air over a large throwing distance, so distributing it optimally in the barn. The Automatic Control Unit (ACU) provides information about the heater’s operating state.
Main advantages
- the generated heat is 100 % beneficial to the pigs: no heat loss;
- no chimney connection necessary;
- easy installation;
- attractive price : performance ratio.
Gas radiators
Gas radiators are especially well-suited if it is necessary to supply pigs with intensive heat in a specific area and for a defined amount of time. The fact that these gas radiators do not require a power supply is a great advantage.
Convection heaters
Hot water heaters continue to be very popular: they work without open combustion inside the barn, which reduces CO2 concentration in the air and improves air quality.
The objective is to maximise heat output. This is achieved by a radiator with a large surface area. The heaters should be mounted directly below the air inlets to heat incoming air.
Renewable energy sources such as wood chips or straw pellets are an ideal solution for producing the hot water.
Delta pipe and Twin pipe
Delta and Twin pipes are especially wellsuited for perforated air channels and DiffAir ceilings. They are made of aluminium 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) they ensure constant room temperatures inside the barn. These heating systems can also be used for pre-heating in the central aisle.
The pipes are anodised for better protection against ammonia. They are of comparatively low weight and can be delivered in different sizes up to a length of 6 m. The pipes are easy to assemble.
Fin heater
The fin heater offered by Big Dutchman is made of galvanized or aluminium piping with an epoxy powder coating. Hot water is pumped through the pipes.
The fins have a large surface area of 1 m² per running metre. Heat emerges from between the fins, giving a strong thermal flow. The spacing between the fins is large enough to ensure that dust does not accumulate.
The pipes are attached to the wall with angles or suspended from the ceiling, if possible directly below the fresh air inlets, thus heating the incoming fresh air. Automatic aeration (for Delta and Twin pipes as well) ensures a high functional reliability of the heating system.
Main advantages
- high heat output: up to 600 watts per running metre;
- low space requirements;
- low weight (aluminium);
- simple, time-saving installation by special coupling.
HeatMaster
The H series HeatMaster models are either suspended along the side of the building at the height of the fresh air inlets or mounted by wall brackets. The main components of our HeatMaster heaters are a fan and a system of stainless steel fins.
The heaters are easy to clean with a highpressure cleaner and resistant to corrosion. The built-in fan provides a wide throwing range and distributes the warm air ideally in the barn.
Main advantages
- the throwing ranges are very wide;
- no flue gases reach the air in the barn;
- a great variety of fuels can be used;
- there is no open flame in the barn.
Zone heating
Piglets need much warmth, especially in the first days after their move to the nursery, so they adapt well during the critical weaning period. Ideally, the resting area should have a temperature of approximately 32 °C.
In addition to traditional full-space heating, hot water zone heating is becoming increasingly popular for nurseries. The zones are created using a covering plate that is fixed at 70 to 80 cm above the slatted floor. The required dimensions of the cover depend on the number of piglets and the depth of the pen.
A deep lip of approx. 20 cm at the front of the cover helps create an insulating blanket of warm air. The heating system (Twin pipe) is installed directly below the cover. The main purpose of this system is to heat the resting area of the piglets. Temperatures can be lower in the rest of the pen, allowing a significant reduction of overall heating costs.
