Outdoor Patio Heater Ravanson OT-1500S — electric oil-filled heater for terraces and patios

Ravanson OT-1500S — electric oil-filled heater for terraces and patios is designed to deliver steady convection heat to localized outdoor seating areas. The unit operates without an open flame and uses an oil-filled radiator element to maintain even surface temperature and gradual heat release. Intended for use on covered terraces, patios and semi-outdoor hospitality zones, this electric oil heater provides a simple way to extend comfortable outdoor time during cooler weather.

Advantages

The oil-filled construction ensures sustained heat output and reduced surface temperature fluctuations compared with some instant-heat devices. As an electric heater it produces no combustion byproducts and does not require fuel storage on site. Its design allows for quiet operation and low maintenance since the heating medium circulates internally, reducing the need for frequent servicing. The compact footprint and vertical profile make it suitable for placement near seating areas without occupying large floor space.

Suitable for

• Covered residential terraces and patios
• Outdoor seating areas of cafes and small restaurants (under awnings or pergolas)
• Semi-enclosed balconies and garden rooms
• Temporary outdoor warming for events and gatherings in mild to cool weather

Key specifications

• Heating type: electric oil-filled radiator providing convection heat
• Intended application: outdoor and semi-outdoor patio and terrace heating
• Heat distribution: steady, gradual heat release suited to localized areas
• Safety: no open flame; designed for use in covered outdoor spaces (follow local safety guidance)
• Form factor: vertical, compact footprint for placement near seating

How to use

Place the heater on a stable, level surface on your covered patio or terrace, keeping the unit clear of combustible materials and ensuring adequate clearance around all sides. Connect the heater to a suitable outdoor-rated power outlet following all local electrical safety rules; avoid using long or damaged extension cords. Operate the controls according to the unit’s settings to reach the desired comfort level. Allow time for the oil inside the heater to warm up and distribute heat evenly; expect gradual temperature rise rather than instant radiance.

Usage recommendations

Use the heater in covered or semi-enclosed outdoor areas where exposure to direct precipitation is minimized. For safe operation, maintain recommended clearances from fabrics, furniture and walls, and switch off and unplug the unit when not in use. For hospitality settings, position units to provide targeted warmth to guest seating without obstructing walkways.
