How Reznor Electric HVAC Helps Industrial & Commercial Spaces Go Sustainable 

If you manage an industrial or commercial building, going sustainable rarely comes down to one big equipment swap. The real progress comes from cutting wasted heat, improving control, and choosing solutions that fit how your building actually runs. 

Reznor provides HVAC solutions beyond gas, including a dedicated electric range for industrial and commercial spaces. Below, we break down where it fits best, helping facilities managers plan upgrades that support sustainability goals whilst keeping comfort consistent.

1) Start with the two checks that decide your energy spend 

Before you pick products, do a quick walkthrough and answer: 

Where do people actually need comfort? 
Think work areas, packing benches, pick faces, reception points, checkouts, pedestrian routes, and any place people stand still for long periods.  

Where is energy being wasted? 
Doorways, loading bays, warm air trapped at roof level, hot and cold spots that force higher setpoints, or heating running outside true occupancy. 

Once you know where the waste is coming from, you can choose electric solutions that cut it at the source and support your sustainability goals, without sacrificing comfort.

2) Destratification fans: stop paying to heat the roof space 

In tall buildings, warm air naturally rises and builds up at ceiling height. That can leave people at working level feeling cold, whilst energy is spent heating air that is not doing much. 

That is exactly what Destratification Fans are designed to address. They reverse the natural convection process by recirculating warm air back down to working level, helping reduce roof space temperature build-up and improve temperature distribution. 

They are particularly relevant in large open spaces such as warehouses, workshops, and sports facilities. Reznor also highlights benefits including reduced pre-heat time, improved comfort, and a reduction of fuel usage up to 15% in suitable applications.

3) e+ electric warm air: fast response, smarter control 

If your site needs whole-area comfort and you want a gas-free route for warm air heating, the e+ Electric Warm Air Unit Heaters are built for industrial and commercial settings where response time and controllability matter. 

The sustainability win is not only that it is electric, it is how it runs day to day: 

• Adaptive control that monitors and adjusts output to maintain the required room temperature efficiently 

• Rapid heat-up at start-up for quicker comfort when the building comes online 

• The ability to manage up to 16 units from one Signal Pro controller with plug and play connections 

• Fan-only mode on the controller for air circulation in warmer weather 

That combination helps you avoid the usual pattern of overheating to chase cold spots, then cycling hard to recover.

4) Air curtains: protect entrances and stabilise temperatures 

If doors are opening all day, it is not just a comfort issue, it is an efficiency issue. Every door cycle pushes warm air out and pulls cold air in, forcing your heating to recover again and again. 

That is where Air Curtains come in. Reznor describes them as creating comfortable conditions using a powerful down-flow of heated or ambient air, helping reduce heat loss and improve air quality. They can also help reduce outdoor contaminants entering the building, such as dust or insects. 

For busy, customer-facing entrances, the Guardian EC is a solid choice: surface-mounted, with EC fan efficiency and easy day-to-day control via a Wi-Fi enabled controller and app. 

Air curtains work best anywhere footfall is high, including main entrances, lobbies, reception areas, shopfronts, and trade counters. 

Reznor’s range lets you match the unit to the opening and environment: 

• Guardian EC: busy commercial entrances, with EC fan efficiency and app control 

• AC and ACR: compact options for smaller commercial entrances 

• ACT: a robust choice for higher-traffic commercial doorways 

• AB: industrial entrances and larger openings 

The takeaway: protect the entrances where comfort leaks out fastest, so your heating is not constantly playing catch-up.

5) Electrical radiant plaque heaters: heat the zone, not the whole volume 

Some buildings do not need blanket heating everywhere. If you have high ceilings, large openings, or only certain areas occupied for long periods, targeted heat can be a smarter route to efficiency. 

Electrical Radiant Plaque Heaters provide instant high frequency infrared heat, focused exactly where required. Rather than trying to warm the entire air volume of a large space, radiant heating supports comfort in the areas that matter most. 

This approach is useful for: 

• Work zones in industrial and warehousing spaces 

• Areas affected by frequent air change 

• Spot heating requirements where rapid warmth is needed

6) EuroT+ with an electrical option: bespoke HVAC built around your application 

Some facilities need more than heating alone. You might be balancing heating, ventilation, and optional cooling, or replacing an older system where downtime and access constraints matter. 

The EuroT+ heating, ventilation and cooling unit is designed for retrofit and new installations, suitable for internal or external mounting, and available with multiple fuel options including an electrical option. It is also custom built to suit each application, with a compact approach aimed at simplifying retrofitting and minimising disruption. 

For electrification plans, that flexibility can be the difference between a concept and a solution that fits the building and the programme.

7) LIRA air-to-air heat pumps: one system for heating and cooling 

If you need heating in winter and cooling in summer, the A+++ LIRA industrial air-to-air heat pump gives you both in one system for commercial and industrial spaces. 

LIRA is designed for European climates and is built to keep operating reliably even at temperatures as low as -20°C. As an air-to-air heat pump, it transfers heat between outdoor and indoor units using refrigerant, so there is no water circuit. You can choose free-blowing or ducted indoor units to suit the building layout. 

The takeaway: LIRA is a practical route to efficient, year-round comfort for sites looking to move towards a gas-free heating and cooling solution. 

Turning targets into action 

Sustainability in HVAC is not about making buildings colder. It is about reducing waste whilst improving control. 

The strongest results often come from combining technologies that solve different problems: 

• e+ electric warm air for whole-area comfort 

• Destratification fans to keep heat at working level 

• Air curtains to reduce losses at doors 

• Radiant plaque heaters for targeted zones 

• EuroT+ (electric option) where you need a bespoke HVAC approach 

That is what it means to be a solutions provider beyond just gas. One joined-up electric range that can be designed around your space, your operating realities, and your sustainability goals.
