Why choose a High-Efficiency Heating System for my Factory?

Reduced energy costs

With the ever-increasing rise in the purchase price of fuel and soaring energy tariffs, now more than ever businesses must ensure that the existing heating systems in place are fit for purpose and of the highest efficiencies to prevent wasted energy and increased energy costs. 

Efficient temperature control

Many manufacturing industries, such as steel, moulding, and food manufacturing, are very much reliant on precise and consistent temperature control. Control is achieved through accurate heating of the areas and expensive plant machinery to ensure product quality and process efficiency. 

Fully compliant with temperature regulations

Temperatures in the indoor workplace are covered by the Workplace (Health, Safety and Welfare) Regulations 1992, which place a legal obligation on employers to provide a ‘reasonable’ temperature in the workplace. 

The Approved Code of Practice suggests the minimum temperature in a workplace should normally be at least 16 degrees Celsius, if however, the work involves rigorous physical effort, the temperature should be at least 13 degrees Celsius. These temperatures are not absolute legal requirements; the employer has a duty to determine what reasonable comfort will be in the individual circumstance.

How to Heat a Factory?

Delivering an efficient and effective heating solution for a large factory premises can present several challenges for our design team and it’s essential that great care and attention must be taken from the start to ensure we fully understand and deliver against your project brief.

To help our team identify the most efficient and effective form of Heating for your Factory there are several factors for OKEL to consider:

  • Age of the building and levels of insulation

  • Dimensions and maximum height to the apex

  • Ideal temperature for the customer to achieve quality manufacturing

  • Health and Safety guidance for working temperatures

  • Manufacturing processes and onsite machinery and whether these generate heat

  • Layout of the area; mezzanine floors, plant machinery and office space

  • Extraction systems

  • Fuel type available on site

  • Hours of operation

Great care must be taken to ensure that OKEL’s chosen design maximises efficiency by ensuring all the areas highlighted above are factored into the initial planning and design stages and that the equipment chosen for each customer project is of the highest efficiency and supported by intelligent self-optimising controls to achieve optimum performance throughout the year.

No matter what type of industry you are working in there are 2 main heating concepts to consider when looking at the most effective and efficient way to heat your factory; and these are Warm air and Radiant.

Benefits of Heating your Factory with Warm Air Heating?

The most modern and effective approach to heating large open plan space, OKEL specialises in the bespoke design and installation of warm air heating systems that work by warming the air within the area and utilising the heaters integral fans to move the warm air around to provide an even distribution of heat throughout the whole area.

  • Energy savings of up to 30% can be achieved with OKEL’s carefully thought-out warm air designs 

  • Natural Gas, LPG, and Electric Fuel Solutions Available

  • Erp Compliant in accordance with the latest Eco Design Directive

  • Fully modulating heaters that minimise energy usage by using only the necessary kws of heat to maintain a steady and desired temperature throughout the factory.  

  • Range of heater sizes to suit all size areas

  • Wall or Ceiling mount designs that will ensure the heaters are out of harm’s way whilst creating space on your factory floor

  • Excellent air flow – minimising hot and cold spots

  • Systems individually designed with combined destratification to maximise efficiency by delivering an even distribution of warm air and preventing heat loss from above. 

  • Horizontal and vertical air distribution to blow warm air in any direction

  • In addition to the heater’s functionalities, the heater model chosen has a summer ventilation mode to deliver continuous air circulation throughout the premises – perfect for the summer months.

  • Facility to connect to a Building Management System  

  • Intelligent user-friendly heater controls to deliver optimum performance and lower energy usage

  • Comprehensive manufacturers warranties to give continued peace of mind post installation

Benefits of Heating your Factory with Radiant Heating?

Perfect for spot heating particularly in poorly insulated open plan areas and provides an efficient and cost saving solution by heating only the people or objects that it meets. The effect of radiant heat is felt almost immediately and it ensures a long period of retained heat so that the tubes can be switched off well before the end of the working day, making it an efficient and cost-effective solution.

  • No air movement – perfect for dusty environments
  • Rapid heat up time and long periods of retained heat
  • Provides spot localised heating or complete coverage
  • Minimises heat losses in poorly insulated buildings
  • Does not directly heat the air – heats only people or objects that it encounters
  • Natural Gas, Electric and LPG fuel types
  • Low noise level
  • Low energy consumption

Factory Heating Testimonials

“From initial contact to the commissioning team OKEL performed at every level to ensure the designed heating and destratification system was seamlessly installed throughout our factory. Working in partnership with both their heating and electrical engineers we incurred minimal disruptions to operations and with the majority of works conducted 15 metres above the whole factory. It was a pleasure to work with a knowledgeable and professional business and would highly recommend them.”

Phillip Ward – Operations Director – Strongdor

“Mark and his team were First Class. The heating system OKEL installed is extremely neat and works well and I would not hesitate to recommend them to other companies for industrial heating.”

Anthony Jewell – Managing Director  – Anilox Laser Technology

“After the initial installation we had some questions around the heater controls, OKEL were quick to provide support, and it was reassuring to know that the personalised customer service continued after the sale”
