Draper Bottle-Mounted Propane Space Heater, 15,354 BTU/4.5kW

The Draper PSH-RAD15 is a compact, lightweight bottle-mounted propane radiant heater designed for portable outdoor and semi-outdoor use in areas of up to 80m². Where the PSH-RAD15A stands independently on its own tubular stand, the PSH-RAD15 mounts directly onto the rim of the propane cylinder via a steel tubular bottle clamp — eliminating the need for a separate stand and producing one of the most compact, self-contained portable heating solutions available. Built around Grade A ceramic radiant plates with two power settings between 3kW and 4.5kW (10,250–15,354 BTU), an integral gas safety valve, and supplied with a hose, regulator, and 90° connector, the PSH-RAD15 is an exceptionally practical heater for patios, outdoor work areas, market stalls, camping, and events where minimum setup and maximum portability are the priority.

Key Features

The bottle-clamp mounting system is the PSH-RAD15's defining practical feature. By clamping securely to the rim of the propane cylinder rather than standing independently, the heater and gas supply become a single, self-contained unit that sets up in seconds and requires no ground space beyond the cylinder footprint itself. This makes it the most compact and quickest-to-deploy option in the Draper radiant heater range — particularly valuable for market traders, outdoor hospitality, construction sites, and anyone who needs effective heating with minimal setup time and equipment.

The Grade A ceramic radiant plates deliver efficient infrared heat that warms people and objects directly in the beam rather than attempting to heat the surrounding air — highly effective in open or semi-open outdoor environments where convection heat disperses rapidly in any breeze. The heater head angle is adjustable, allowing heat to be directed precisely toward the area or people that need it rather than radiating in a fixed direction. Two power settings — low at 3kW (10,250 BTU) covering up to 20m², and high at 4.5kW (15,354 BTU) covering up to 80m² — allow output to be matched to conditions and requirements, with fuel consumption of 0.22kg/h on low and 0.33kg/h on high providing a practical guide to gas duration.

The integral gas safety valve shuts off the gas supply immediately if the heater fails to light or if the flame is extinguished for any reason, preventing the accumulation of unburned gas around the heater — an important safety feature for any gas appliance used in public or outdoor environments. The PSH-RAD15 is designed for use with G31 propane cylinders of 7–15kg capacity at 37mbar normal gas pressure, and is supplied with a 90° hose connector, regulator, and 0.7m hose. At just 1.8kg it is the lightest heater in the Draper propane range, making it as easy to transport and store as any accessory in an outdoor kit.

Specifications

Who Is This Heater For?

The PSH-RAD15 is ideal for anyone who needs the most compact and portable propane heating solution possible without sacrificing meaningful heat output. Market traders and outdoor hospitality operators who need quick-setup heating at a stall or table will find the bottle-clamp format eliminates the need for a separate stand and reduces the equipment needed to a single unit. Campers, festival-goers, and outdoor enthusiasts who want a lightweight, packable heat source for cool evenings will appreciate the 1.8kg weight and self-contained design. Construction workers, gardeners, and site users who need supplementary warmth in open areas will find the 4.5kW output adequate for most practical requirements. The PSH-RAD15 is also a natural companion to the PSH-RAD15A for users who want the option of either bottle-mounted or free-standing operation with the same heating performance.

How Does the PSH-RAD15 Compare to the PSH-RAD15A?

The PSH-RAD15 and PSH-RAD15A share identical heating performance — the same Grade A ceramic plates, the same 3–4.5kW output range, the same gas safety valve, and the same coverage area of 20–80m². The key difference is the mounting system. The PSH-RAD15 clamps directly to the propane cylinder for the most compact, self-contained setup possible, while the PSH-RAD15A stands independently on its own tubular steel stand with a longer 1.5m hose allowing the heater to be positioned away from the cylinder. The PSH-RAD15 is the right choice for maximum portability and minimum setup; the PSH-RAD15A suits applications where a freestanding unit is preferable or where the heater needs to be positioned independently from the gas supply.

Why Choose the Draper PSH-RAD15?

The PSH-RAD15 is the most portable and quickest-to-deploy propane heater in the Draper range, and for many outdoor applications that is precisely what matters most. The bottle-clamp design removes the need for a separate stand entirely, reducing setup to connecting the hose and lighting — a genuinely useful advantage when time, space, and simplicity are at a premium. The Grade A ceramic plates and gas safety valve ensure the heating performance and safety standard match those of the freestanding PSH-RAD15A, so the choice between the two is purely about how and where the heater will be used rather than any difference in quality or output. For anyone who needs effective, immediate, and genuinely portable propane radiant heating in the most compact format available, the PSH-RAD15 is the straightforward choice.
