Safety Features
This appliance incorporates a number of safety devices. In addition to the Important Safety Advice section, your attention is drawn to the following.
Tilt Switch
- The tilt switch will prevent the heater from working if it is accidentally tipped over on its side.
- If the radiator is tipped over while it is hot, disconnect the power and allow it to cool, then stand the radiator back upright. Reconnect the power; normal operation should be resumed.
Overheat Protection
- The heater is fitted with a temperature limiter, which will reduce the output of the heater should it overheat for any reason. The product will return to normal operation after the cause of the overheating has been rectified.
Parts
- On/Off & heat selector dial
- Thermostat dial
- Neon
- Carry handle
- Ventilation openings
- Castors
- Cord wrap
Fitting The Castors
- To fit the castors, turn the radiator upside down on carpet or another soft surface to avoid damage. Warning: The radiator is heavy; ensure that it is supported to prevent it from toppling. Ask a second person to help with this if necessary.
- To fit the castors, place the castor plates in position and secure using the wing bolts provided. There are guides to ensure the correct positioning and orientation of the castor plate.
- Return the radiator to the correct orientation so it rests on the castors. The product is now ready for use.
Operation
Note: When turning on the product for the first time, it may emit a little smoke and smell for a short period. This is normal and will subside. Position the heater at least 1 m from the wall and other surroundings. We recommend maximising the clearance where possible.
On
Switch the product ON by turning the dial (1) clockwise to the desired heat setting. There are 3 heat settings to choose from, as indicated in the specifications table. The neon (3) will indicate the heat setting selected.
Thermostat
To set the temperature, turn the thermostat dial (2) clockwise until the required setting is reached. Alternatively, to heat a cold room quickly, turn the thermostat dial up fully. To decrease the set temperature, turn the dial anti-clockwise.
Cleaning
Over time, dust can accumulate on the heater, which can affect performance. It is recommended to clean the unit at least once a month.
- Turn the unit OFF and disconnect the appliance from the power supply.
- Remove any dust build-up with a soft brush.
- Wipe the surface of the unit with a soft, damp cloth. Mild detergent can be used for any stubborn marks.
IMPORTANT: The control panel and other parts must not come into contact with water or any other liquids.
Storage
If not using the unit for an extended period of time, after cleaning, please:
- Ensure the control switch is OFF and remove the plug from the power outlet.
- Cover the unit and store it upright in a location where it will not receive direct sunlight. NB: Prolonged exposure to direct sunlight will discolour the unit.

Dimplex DHOC15 1.5kW Oil Column Heater-FAQs
What are the key specifications of the Dimplex DHOC15 1.5kW Oil Column Heater?
The Dimplex DHOC15 is a 1.5 kW oil-filled column heater designed for indoor use. It operates on 220–240 V at 50/60 Hz, offers three heat settings (around 600 W, 900 W, and 1500 W), and has a castor-mounted body weighing about 7.96 kg. Its dimensions are roughly 245 × 380 × 630 mm, and it includes an adjustable thermostat and easy-roll castors for portability.
How do the adjustable thermostat and heat settings work on this heater?
The DHOC15 has a thermostat dial and a heat selector dial. Turn the heat selector to choose one of the three power levels based on your comfort needs. Then use the thermostat dial to adjust the temperature more precisely — higher for quicker heat and lower to maintain warmth. The neon indicator shows when it’s powered on.
Is the Dimplex DHOC15 safe to use around children and pets?
Yes, but with precautions. Parts of the heater can become hot to the touch during operation, which could pose a burn risk. It should be placed on a stable surface away from high-traffic areas. Children should be supervised and not left alone with the operating heater. Also, keep flammable materials at least 1 m away.
What safety features are included in the DHOC15 heater?
The heater includes a tilt switch that stops operation if it’s accidentally tipped over, and a thermal overheat protection system that reduces output if internal temperatures get too high. These features help prevent hazards, but users must still follow placement and clearance guidelines for safe use.
Where should I place the heater for optimal performance and safety?
Place the DHOC15 on a flat, stable, horizontal surface with clear space around it. Do not use it in wet areas like bathrooms or outdoors. Avoid placing it directly under a socket or behind curtains/furniture, as obstructed airflow may cause overheating.
Can the Dimplex DHOC15 be used with extension leads or power boards?
No. Using an extension cable or power board increases the risk of overheating and fire hazards because these heaters draw significant current. Always plug the heater directly into an appropriately rated wall socket with the right voltage (220–240 V).
How do I maintain and clean the oil column heater?
Before cleaning, always disconnect the power and let the unit cool completely. Wipe dust from the outer surface and ensure ventilation openings are clear. Do not use abrasive cleaners or immerse the heater in water. Periodic cleaning ensures efficient heat circulation.
Can the DHOC15 heater overheat, and how do I handle it?
The heater has built-in overheat protection, but if it cuts out, it indicates excessive heat. Unplug the unit, let it cool, and check for blocked airflow or proximity to flammable items. Remove obstructions before restarting. If issues persist, seek professional advice.
Is this heater suitable for all room sizes?
The DHOC15’s 1.5 kW output is ideal for medium-sized rooms (e.g., living spaces or bedrooms). Its adjustable thermostat and multiple heat levels let you fine-tune warmth, but performance also depends on insulation, ceiling height, and outdoor temperatures.
What should I do if the heater stops working properly?
First, check that the unit is upright, plugged in securely, and that no obstructions block airflow. If it still won’t heat or shows abnormal behavior, unplug and let it cool. Continued issues may mean contacting Dimplex support or a qualified technician — do not attempt DIY repairs as this can void warranties and pose safety risks.
