When was the last time you serviced your room heater? If you’re like most people, probably never! We often plug in our heaters as soon as the chill sets in, expecting them to work perfectly without a second thought. But just like your air conditioner or refrigerator, room heaters also need regular maintenance to perform their best and last longer. Skipping servicing can lead to poor heating, higher energy bills, or even unexpected breakdowns when you need warmth the most.

Did you know that not all heaters are the same? Whether you use an oil-filled heater, a fan heater, or an infrared heater, each type requires specific care to keep it running efficiently. Don’t worry if this sounds overwhelming, we’ve got you covered!

In this heater maintenance guide, we are revealing some DIY service tips tailored to each heater type. These hacks will help you ensure your heater delivers consistent warmth, save on energy bills, and avoid costly repairs down the road. So, before you switch on your heater this winter, take a little time to show it some care.

Why is room heater maintenance essential?

Regular maintenance is the key to keeping your room heater running efficiently, safely, and for a long time. Dust and dirt can clog its components, reducing its heating power and making it work harder, which increases energy consumption. Servicing helps the heater distribute heat evenly, ensuring your space stays warm and cosy.

More importantly, a well-maintained heater reduces the risk of overheating or electrical faults, making it safer to use. By taking the time to care for your heater, you not only save on energy bills but also prevent costly repairs or replacements in the future.

What are the signs that your heater needs immediate servicing?

If you are noticing any of the below signs in your heater, you need to get it repaired at the earliest:

Reduced heat output: If your heater isn’t warming up the room like it used to, it’s time to check for blockages or worn-out components.

Strange noises: Unusual sounds like buzzing, clicking, or rattling could indicate mechanical or electrical issues.

Burning smell: A burning or unusual odour may signal dust buildup or overheating, which needs immediate attention.

Uneven heating: Some parts of the room feel warm while others remain cold, pointing to inefficiency or internal blockages.

Higher energy bills: A sudden spike in your electricity usage could mean your heater is struggling to work efficiently.

Frequent shutdowns: If your heater keeps turning off unexpectedly, there could be an underlying issue requiring urgent servicing.

Understanding the types of room heaters

Since each type of heater requires a different type of servicing, let's first understand the key differences between each:

Oil-Filled Heaters	Fan Heaters	Infrared Heaters
Provides consistent and even heating	Heats rooms quickly	Emits infrared rays to heat objects directly
Energy-efficient and silent	Compact and portable	Ideal for smaller spaces
Takes longer to heat up but retains warmth longer	Prone to dust accumulation	Silent operation
Heavier and less portable	Can dry out air in the room	Energy-efficient for direct, localised heating
Suitable for larger rooms and long-term use	Noisy during operation	Limited to heating small areas
Requires more maintenance due to oil levels	Less energy-efficient compared to oil-filled heaters	Not effective for heating entire rooms

Maintenance hacks for oil-filled heaters

Oil-filled heaters are known for their consistent warmth, but just like any other appliance, they need a little care to keep running smoothly. Here’s a simple step-by-step guide to help you maintain it.

1. Clean the dust and dirt

Over time, dust and dirt can build up on the oil-filled heater’s fins and body, reducing its efficiency. Use a vacuum cleaner with a brush attachment or a soft cloth to gently clean the surface. Don’t forget the hard-to-reach spots! Regular cleaning helps your heater work better and keeps the air cleaner in your room.

2. Check for oil leaks

One of the key things to look out for is oil leaks. If your heater starts leaking, it’s time to get it serviced. Always make sure the heater is standing upright and avoid tilting it, as this can cause the oil to leak. If you notice any oil stains, it’s a red flag!

3. Test the thermostat and switches

The thermostat controls how hot your heater gets, so it’s important to check it regularly. Make sure the thermostat is responding to temperature changes and that all the switches are working properly. If anything feels off, it’s worth getting checked by the professional.

4. Storing it during the off-season

When the winter ends, don’t just shove your heater in a corner and forget about it! Store it in a dry, cool place to avoid damage. Make sure it’s clean and unplugged before storing it away for the season.

Maintenance tips for fan heaters

Here’s a simple guide to help you maintain your fan heater, so it stays in top condition all winter long.

1. Clean the fan blades and vents

Dust and debris can clog the fan blades and vents, preventing your heater from working at its best. Use a soft brush or cloth to clean the fan blades gently. Be sure to clean the vents as well to allow proper airflow.

2. Remove dust from the motor and internal components

As dust accumulates inside your fan heater over time, especially in the motor and other internal components, use a vacuum cleaner with a nozzle attachment or compressed air to blow it out. This will prevent blockages and ensure the heater operates smoothly.

3. Test the thermostat and temperature settings

To make sure your heater is delivering the right temperature, check the thermostat and temperature settings. Test it by turning the heater on and adjusting the settings. If the temperature seems off or doesn’t match what’s set, it could mean the thermostat needs attention. It is advisable to call a professional for accurate checking.

4. Safety precautions

Fan heaters work by blowing warm air, so safety is essential. Always keep your heater away from water to avoid electrical hazards. Also, keep it clear of any flammable objects, like curtains or papers. These simple precautions can prevent accidents and keep your heater running safely.

Maintenance hacks for infrared heaters

Follow these simple maintenance tips and your infrared heater will continue to provide effective, silent warmth when you need it most:

1. Clean the reflectors and infrared bulbs

Heat output gets reduced as the reflectors and infrared bulbs gather dust or dirt over time. To clean them, use a soft cloth or a microfiber duster to gently wipe the surface. Be careful not to damage the bulbs, as they can be delicate.

2. Inspect wires and connections

Always check the wires and connections for signs of wear, fraying, or any damage. If you spot any issues, it’s important to address them immediately. Damaged wiring can lead to safety risks, so never ignore them. If needed, consult a professional to fix any electrical issues.

3. Ensure proper positioning

For the best heat distribution, make sure your infrared heater is positioned properly. It should be placed in an open area without any obstructions, so the infrared rays can reach you directly. Avoid placing it near walls or corners, as this can affect the heater’s performance.

4. Handle and replace infrared bulbs safely

If your infrared bulb burns out, it’s important to replace it with the same type and wattage. Always turn off and unplug the heater before handling the bulb. Wear gloves to avoid touching the new bulb with bare hands, as oils from your skin can damage it. Follow the manufacturer’s instructions for safe replacement.
