Step away from gas: 4-point plan for your factory

3 min. reading - published on October 11, 2022

Energy prices are a big issue now and this is the right time to look and reflect on the carbon emissions produced by industries. Depending on the country’s energy strategies for either gas or electricity, industrial buildings should be equipped with either heat pump technology or with more efficient cooling and heating technologies.

It all starts with mapping the current situation. Then, preventive measures can be taken and as a result of that, a calculation can be made for the heating, ventilation, and cooling requirements. 

1. Analysis of the building (external and internal heat load)

The first and easiest step to get the desired indoor temperature is to analyze the building. To reduce the heating costs, the starting point is to find the external and internal heat load points. The checkpoints of heat load are:


  • the solar heat/insulation of a building
  • the outside air temperature
  • infiltration of outside air into the building in case of old, leaky, or cracked building walls
  • Ventilated air: the outside cold/hot air that enters the building without pre-treated


  • the heat emitted by the people present
  • the electrical lighting
  • the heat emitted by equipment and/or the production process
  • transmission heat between different sections of the building

2. Minimize required heating power (energy-saving measures)

After calculating the internal and external heat loads and taking the proper steps to prevent heat loss or heat gain, energy-savings measures can be introduced.

3. Determining heating metrics

Not every building is the same, so it is important to see what is best suited for the building. Every building has different requirements in terms of heating powers and heating needs that are based on the heat delivery system and heating source. 

3A) Determining heating needs (how many hours)

3B) Determining heating power (how many KW)

3C) Determining the delivery system

  • Indirect-fired air heating by means of an air heater
    • Relatively low investment
  • Indirectly fired air heating via Heat Reclaim module
    • Efficient heating combined with sustainable ventilation and cooling.
    • Easy to add to climate control solution, low additional investment.
  • Indirectly fired radiant panels
    • Zone or local heating is possible
    • Radiant heat causes a different perceived temperature, which makes lower hall temperature possible
  • Electric radiant panel
    • Local heating
    • Energy savings due to short heating time, low hall temperature

3D) Determining the heating source

  • Electric heating (only when it is a very low heating requirement)
  • Late temperature (LT) heat pump
  • Medium temperature (MT) heat pump
  • High temperature (HT) heat pump

4. Installation of the energy–efficient four-season climate control system

Oxycom’s patented IntrCooll climate control system can be combined with a natural ventilator box (no extraction fans needed) and a Heat Reclaim Module to create a healthy, fresh and comfortable indoor climate all year round. Additional heating can be provided by connecting the Heat Reclaim Module with a heat pump.

A carbon dioxide (CO2) measuring device can be connected to our system to deliver the required amount of fresh air in winter or shut off the outdoors completely at night and/or on weekends when no fresh air is needed. The Heat Reclaim Module reuses the residual heat generated from machines, processes, heating, lighting, and people. It filters the indoor recirculated air, then mixes it with filtered fresh air. This supplies the production hall with preheated clean and fresh air.

“We are very satisfied with Oxycom's energy-efficient solution which solved the heat problem in our coating department and assembly line. Now we have a pleasant, constant temperature in summer and winter.”
