Gas-fired unit air heaters in industrial applications

The Dutch Gasunie did research on the most effective way of heating an industrial building comparing several heating methods. The best results were achieved by gas-fired unit heaters. (source: ISSO 57).

Under-floor heating was also taken into account in this research and turned out to be less effective due to higher installation and annual running costs. In industrial environments, air heating is used mostly during the day whereas under-floor heating responds slowly, requiring 24 hours per day operation.

 

Effective heating with unit air heaters

An industrial building has to heated only when people are at work and this is exactly what unit air-heaters do. The heater(s) turn on only when the thermostat requires heat. Under-floor heating has a slow response time and it takes a long time before the temperature is at the right level. Also, the annual running costs are higher as this system needs to maintain the temperature overnight.

For normal operating hours (like in shops, garages, sport halls, warehouses or production companies) the best solution is air heating because:

  • Lowest possible annual running cost
  • Low investment for equipment and installation
  • A saving in running costs of approx. 40% can be expected with air heating

Heaters for agricultural markets

Winterwarm also manufactures heaters for use in greenhouses and poultry farming.

Greenhouses

In greenhouses, both DXA and DXC can be applied. Each type of crop (i.e. salad, tomatoes, garden plants) require a specific concentration of CO2 influencing the choice of the heating unit.

The DXA produces CO2 for the growing process as well as water vapour. There is no loss of energy. It is essential to ventilate the greenhouse properly to prevent build-up CO2 for human well behaviour as well as for the crop.

The DXC has a flue to discharge CO2. A combination of DXA and DXC is also possible. 

Poultry farming

Traditionally, poultry houses are heated by so called "open-fired heaters" using gas or oil. For these situations, Winterwarm  offers the DXA (gas-fired) or DXB (oil-fired) heaters.

However, these units produce CO2 and water vapour, so it is necessary to have a high level of ventilation in order to maintain a healthy environment as neither CO2 nor water vapour is required, especially not in cold areas. However, during the proces of ventilating the CO2  and the water vapour out of the building, also the warm air disappears to the outside. This is of course very un-economical.

Therefore, Winterwarm has developed the DXC heater (gas-fired) with a flue. With this new concept with so called "closed combustion"  all CO2 and water vapour is discharged to the outside directly. Advantages of this concept:

  • Saving of approx. 25 % on energy cost
  • Dry environment in the farm
  • Low noise
  • Safe operation (no open flame)
