Winterwarm Heaters: The Energy-Efficient Choice for Industrial Warm Air Heating

 

Winterwarm industrial warm air heaters offer distinct and measurable benefits compared to older or standard conventional warm air heaters.1 These advantages focus heavily on advanced energy efficiency, sophisticated control features, and a versatile range of heating solutions, making them a preferred choice for modern industrial and commercial environments.

 

 

Maximum Efficiency: Lowering Operational Costs with Winterwarm Heaters

 

The primary advantage of choosing a Winterwarm unit is the significant reduction in operating costs, driven by advanced engineering and innovative burner technology:

• Advanced Pre-Mix Burner Technology: Unlike many other warm air heater manufacturers, Winterwarm units incorporate a pre-mix zero governor burner, similar to the highly efficient burners found in modern condensing boilers. This system precisely blends all the gas and air before combustion. This advanced method leads to:

  • Lower NOx Emissions: A cleaner, more complete combustion process drastically reduces harmful NOx (Nitrogen Oxide) emissions.

     

  • Wide Modulation Range: Allows the heater to precisely modulate its heat output to match the room's demand (often down to 20% of max output), preventing energy-wasting cycles and ensuring stable, even heat.

     

• Condensing Technology (HR Series): Winterwarm's HR (High Efficiency) series utilizes condensing technology, achieving thermal efficiencies of over 100% (net). This process recovers heat from flue gases that would typically be wasted, leading to substantial gas savings (up to 25% compared to standard, non-condensing heaters).

   

• EC Fan Technology: Heaters equipped with EC (Electronically Commutated) fans (such as the HR EC-series) drastically cut electricity consumption (up to 25%) and operate with significantly lower noise levels—a key benefit for busy commercial spaces.

 

Advanced Control for Superior Comfort and Consistent Temperatures

 

Winterwarm heaters incorporate smart features that improve comfort while maintaining efficiency:

• Vertical Gradient Control / Delta-T Function: This unique feature (on HR and XR+ models) actively monitors the temperature difference between the floor (working zone) and the ceiling. If a heat buildup is detected at the ceiling, the fan automatically turns on to push the warm air down, acting as a destratification fan before the main burner fires. This optimally utilizes existing heat, ensuring a consistent temperature and further reducing the burner's running time.

   

• OpenTherm Control (HR Series): This technology enables precise heating control, allowing the heater to match the heat delivered exactly to the building's current demand, enhancing both efficiency and comfort.

   

• Centralized Control Systems: Advanced thermostats (like MultiTherm) can manage up to eight heaters simultaneously, offering programmed time blocks and diagnostic functions for seamless operation.

   

 

Versatile Heating Solutions for Every Industrial Application

 

Winterwarm's extensive product range ensures there is an efficient solution for nearly any industrial or commercial setting:

• Multiple Fuel Types: Options include high-efficiency gas-fired (condensing and non-condensing), LPHW (Low Pressure Hot Water) for connection to boilers or heat pumps, and Electric heaters (EH Series), ideal for gas-free locations or when using self-generated solar power.

• Hybrid Options: The innovative Qwikshift Hybrid heaters combine highly efficient heat pump technology with a traditional gas or electric booster for maximum energy flexibility.

• Flexible Installation: With compact designs and various suspension options (horizontal, vertical, or angled), Winterwarm units can be easily integrated into diverse spaces, from high-ceiling warehouses to showrooms.

   

Conclusion:

By combining advanced pre-mix zero governor burner technology with condensing warm air heater design and sophisticated control systems like the Delta-T function, Winterwarm heaters offer a modern, highly efficient, and cost-effective heating solution that goes beyond the capabilities of standard industrial models.

Oil Fired Floor Standing and Ceiling Suspend Warm Air Heaters

​

Powrmatic Oil-Fired Warm Air Heaters (CPx/OUH Series)

 

 

1. Core Technology & Efficiency

 

• ErP 2021 Compliant: All current models meet the strict European EcoDesign (ErP) Directive for seasonal space heating energy efficiency and NOx emissions.

• Low NOx Burner Technology: Utilise pre-fitted and tested Riello high/low pressure jet burners for reduced NOx emissions, keeping units below regulatory limits (e.g., OUH series NOx below 160  mg/kWh.

• Two-Stage Firing: Standard operation is High/Low fire, allowing the heater to reduce output once the required temperature is nearly met, improving efficiency and comfort (similar to a modulating unit).

• Durable Heat Exchanger: Features a robust, proven heat exchanger manufactured from 304-grade stainless steel as standard for long life and reliability, often backed by an extended warranty.

 

2. Versatility & Installation

 

• Fuel Flexibility: Capable of running on either 35-second oil (Gas Oil/Red Diesel) or 28-second oil (Kerosene), providing adaptability based on site requirements. Bio-fuel options may also be available.

• Model Configurations:

  • OUH (Suspended): Available in Axial Fan (F) for free-blowing applications or Centrifugal Fan (C/D) for connection to ducted systems.

  • CPx (Cabinet/Floor Standing): Available in upright configurations, with options for free-blowing (adjustable heads) or ducted setups.

• Oil & Flue Connections: Units are indirect-fired and room-sealed, supplied with a fire valve and oil line filter (loose) for on-site fitting, ensuring a sealed combustion circuit.

 

3. Outputs & Applications

 

• Output Range (Suspended OUH): Models typically range from $20 kW to 60 kW for suspended applications where floor space is limited.

• Output Range (Floor Standing CPx): Cabinet heaters are available in larger outputs, extending to over 100 kW for heating vast industrial spaces.

• Target Applications: Ideal for large volume commercial and industrial premises where oil is the preferred fuel source, including: Warehouses, Factories, Workshops, Garages, and Logistics Centres

 

4. Control & Maintenance

 

• Advanced Control: Controlled by the Powrmatic MC200 Optimised Start Controller, which offers:
