The Complete Guide to Commercial Outdoor Heating: How to Heat a Restaurant, Hotel, or Venue Patio
Outdoor dining, rooftop bars, hotel terraces, and event venues all share one critical challenge: keeping guests comfortable when temperatures drop. The right commercial outdoor heating system doesn't just solve that problem — it extends your operational season, increases revenue per cover, and signals a level of quality and care that guests notice immediately.
This guide covers everything hospitality operators, contractors, and commercial designers need to know before specifying an outdoor heating system — from choosing between electric and gas, to sizing, installation, and selecting the right product for your venue type.
Why Outdoor Heating Matters for Commercial Venues
Research consistently shows that heated outdoor spaces deliver measurable commercial returns. Venues with effective patio heating report higher average covers per service, extended trading hours into cooler months, and significantly improved guest satisfaction scores for outdoor areas.
Beyond revenue, the quality of your outdoor heating signals something about your brand. A premium restaurant with exposed propane mushroom heaters reads as an afterthought. The same space with discreetly integrated Bromic infrared heating reads as considered, intentional design — exactly the kind of detail that earns reviews and repeat visits.
Venues with effective outdoor heating report up to 19% higher outdoor occupancy rates and a meaningful extension of their outdoor trading season — in some climates by three months or more.

Electric vs Gas: Which Is Right for Your Venue?
Choosing between electric and gas heating is the first and most consequential decision in any commercial heating specification. Both technologies deliver radiant infrared heat, but they perform differently depending on your venue's architecture, exposure level, and infrastructure.
Electric Infrared Heating
Electric patio heaters are the preferred specification for architecturally designed commercial spaces where design integrity and quiet operation are non-negotiable. They mount discreetly to ceilings and walls, produce no combustion byproducts, and require no ventilation clearances — making them ideal for covered or semi-enclosed outdoor areas.
Bromic's electric range includes the Platinum Smart-Heat™ Electric, Cobalt Smart-Heat® Electric, and Tungsten Smart-Heat® Electric — each offering different output levels and mounting configurations for different venue types.
Best for: Covered terraces, pergola structures, hotel lobbies with outdoor access, rooftop bars with partial cover, restaurant dining rooms with retractable roofs.
Gas Infrared Heating
Gas heating delivers significantly higher BTU output than electric alternatives, making it the right specification for open-air venues, large terraces, and spaces with high wind exposure. Bromic's gas range is engineered with patented wind-resistance technology that maintains consistent heat output in conditions up to 12mph — a critical consideration for rooftop and open-air applications.
Available in natural gas and propane configurations, gas heaters offer flexibility for venues without established electrical infrastructure at the point of installation.
Best for: Open-air restaurant terraces, exposed rooftop bars, large event venues, pool areas, and high-volume outdoor dining areas.

Commercial Heating by Venue Type
Restaurants & Cafes
For restaurants, the primary goal is maximising outdoor covers across as many services as possible. Electric infrared heating is preferred for covered dining terraces — the quiet operation doesn't interfere with the dining experience, and the discreet ceiling-mounted profile doesn't intrude on the table setting. For open-air terraces, Bromic Tungsten Gas delivers the output and wind resistance needed to keep diners comfortable even on exposed sites.
Key consideration: plan heating zones around your table layout rather than treating the terrace as a single zone. Focused directional heat at table level outperforms ambient heating that dissipates before reaching seated guests.
Hotels & Resorts
Hotel outdoor spaces — terraces, pool areas, rooftop bars, and alfresco dining rooms — each have different heating requirements. The consistent thread is design: a luxury hotel's outdoor areas need heating that feels as considered as the interior. Bromic's Eclipse pendant heater, which combines infrared warming with dimmable LED lighting, is a particularly strong specification for hotel terraces where ambience is as important as warmth.
Rooftop Bars & Lounges
Rooftop installations face the greatest wind challenge of any commercial venue type. Gas heating with Bromic's wind-resistance technology is the standard specification for fully exposed rooftops. For partially covered or pergola-protected rooftop areas, electric ceiling-mounted heating offers a cleaner installation and better design integration.
Event & Entertainment Venues
Event venues require flexibility — the heating layout that works for a seated dinner is different from a standing cocktail reception. Bromic's Tungsten Freestanding Gas heater addresses this with a modular, portable design that can be repositioned between events without any fixed installation. For permanent installations across fixed zones, ceiling-mounted electric or gas provides consistent, reliable coverage.

How to Size a Commercial Outdoor Heating System
Accurate sizing is the most commonly overlooked aspect of commercial heating specification. Under-spec a system and guests are cold. Over-spec and you've wasted capital and operating budget. The key variables are:
Space Dimensions
Total square footage of the area to be heated, accounting for zones and seating layouts rather than treating the entire space as one uniform area.
Ceiling Height
Higher ceilings require higher wattage units. A 4500W electric unit effective at 9 feet may require a 6000W unit at 12 feet to maintain equivalent heat at floor level.
Wind Exposure
Open or exposed sites require gas heating with wind-resistance technology, or electric units positioned to minimize cross-draft dissipation.
Mounting Location
Ceiling mounting delivers more even coverage than wall mounting. The angle and position of each unit should be planned around the seating layout, not the structural grid.
As a general starting point: a single 2400W electric unit covers approximately 13 square feet of effective heat zone. A 4500W unit covers up to 22 square feet. Bromic's gas range covers up to 215 square feet per unit under optimal conditions. For multi-zone commercial installations, we recommend a professional site assessment before finalising your specification.
Installation Requirements for Commercial Heaters
All commercial outdoor heater installations require licensed tradespeople and must comply with local building codes. The specific requirements vary by heater type:
Electric heaters require a dedicated electrical circuit rated for the unit's wattage, installed by a licensed electrician. For ceiling-mounted units, structural mounting points must be confirmed prior to installation to ensure they can safely support the heater's weight and any vibration loads.
Gas heaters require connection to a natural gas line or propane supply by a licensed gas fitter. Clearance distances from combustible materials must be observed in accordance with the manufacturer's specifications and local building codes. Ventilation requirements apply to enclosed or semi-enclosed spaces.
For large commercial projects spanning multiple zones or venues, AlphaCaveHQ can connect you with qualified installation contractors and provide full project documentation to support your building consent process.

Smart Controls & Automation for Commercial Heating
Modern commercial heating systems don't require manual operation at each unit. Bromic's Affinity Smart-Heat® Controls Collection enables centralized management across multiple heaters and zones from a single interface — wall-mounted, app-based, or integrated with your building automation system.
For hospitality venues, this translates to practical operational benefits: front-of-house staff can activate or adjust heating zones from a central point as the evening progresses, rather than manually operating individual units. Scheduling allows the system to pre-heat outdoor areas before service without staff intervention. Multi-zone management means different areas of a venue — a covered terrace and an open rooftop, for example — can be controlled independently at appropriate output levels.
For large hotels and multi-venue operators, Bromic's system supports integration with BMS (Building Management Systems) via the appropriate expander hardware, enabling heating to be managed as part of a property-wide energy and operations platform.
