How to specify infrared heaters for hospitality in 2026

What “best” should mean for a venue

Consumer reviews rank heaters by price and looks. A venue has different criteria: it will run the unit for six hours a day through winter, it will be cleaned by staff who did not install it, and it needs a replacement element in three years without importing a new fixture.

So the useful ranking criteria are duty cycle, serviceability, control granularity and certification — not the number on the box. A 3.2 kW heater with no spare-part supply is worse value than a 2.4 kW heater you can repair.

• Duty cycle: can it run continuously for a full service, not just an evening?
• Serviceability: is the element replaceable, and at what price and lead time?
• Control granularity: can you run half the terrace without running the whole circuit?
• Certification: does the unit carry the mark your market requires, with documents?
• Fixings and IP rating: does the mounting hardware suit the wall, and is IPX4 enough for the position?

How much output does a terrace actually need?

The industry shorthand is watts per square metre, and it works well enough to start a conversation. A sheltered, glazed terrace needs roughly 80–100 W/m². A terrace with one or two open sides needs 110–130 W/m². An exposed rooftop or a site with a prevailing wind needs 130–160 W/m², and a windbreak will do more good than another kilowatt.

Mounting height changes the calculation. Radiant intensity falls with distance, so a heater at 2.5 m delivers materially less to a seated guest than the same unit at 2.0 m. In spaces with ceilings above 3 m, plan on higher output per fixture or accept coverage of the seating cluster rather than the whole floor.

Wind is a layout problem, not a wattage problem

Every experienced operator has seen a terrace with four heaters running and guests still in coats. Almost always the heaters are fighting air movement that a screen would have stopped. Glass panels, planter walls, awning sides and pergola infills cost less per square metre of comfort than additional heaters, and they reduce running cost permanently.

Place heaters on the leeward side of the seating, facing across it. A heater mounted on the windward wall blows its radiant field into moving air; the same heater mounted opposite works.

Certification by market

• European Union / EEA: CE marking, with EMC and safety documentation; RoHS for materials.
• United Kingdom: check the current UKCA position with your importer — CE and UKCA requirements have diverged.
• Australia and New Zealand: SAA certification is the usual expectation for electrical appliances.
• Saudi Arabia and the Gulf: SASO for market access; confirm any additional efficiency labelling.
• China: CCC for domestic sale.
• Every market: ask for the certificate, not the logo. A declaration of conformity without a test report is not a specification.

The five mistakes we see most often

• Sizing on floor area when only a third of the floor is seating.
• Buying the highest wattage available instead of fixing the wind.
• Single-circuit installation, so the whole terrace runs for four guests.
• Forgetting that 3.2 kW draws 13.9 A and a four-heater terrace needs a proper distribution board.
• No spare-element plan, then discovering the model is discontinued two winters later.
