Workshop heater - how do you look after it? Quick reference guide

Workshop heater is a device that can transform working comfort in the cold months. In workshops, warehouses, production halls or on construction sites, it gives quick and pinpoint heat exactly where it is needed. However, like any heating equipment, it requires proper care. Regular maintenance ensures that the heater lasts longer, uses less fuel and remains completely safe.

Below you will find a practical guide explaining how to take care of oil heaters for workshopsin order to avoid breakdowns and enjoy their reliable operation for years.

Why is workshop heater maintenance so important?

Lack of proper care results:

decrease in heating efficiency,
higher fuel consumption,
greater risk of failure at key moments,
or even a threat to occupational safety.

Well maintained oil heater operates stably, generates less exhaust fumes and provides even heat, resulting in better workplace conditions.

Regular cleaning - the first step to a long heater life

Dust and dirt are the natural 'enemies' of the heater. They settle inside the appliance, restrict airflow and interfere with the combustion process.

Fuel filter - Check it every few weeks for contamination. A dirty filter causes a loss of power and firing problems. If you can see deposits - replace it.
Fuel nozzle - A dirty nozzle means less efficient combustion and smoke. It is worth cleaning or replacing it at least once a season.
Housing and inlet grilles - Dust collects especially in these areas. It is best removed with compressed air or a soft brush.

Checking the fuel and supply system

The quality of the fuel directly affects the service life of the workshop heater.

Use only tested fuel - Diesel or fuel oil in accordance with the manufacturer's recommendations. Cheap substitutes can damage the pump and cause filter clogging.
Check for leaks in the hoses - Even minor leaks can inflate the system and cause firing problems.
Do not store fuel for too long - over time, it loses its properties and forms deposits.

Fan and electrical installation

Although the combustion system plays a major role in an oil heater, the fan and electrics are equally important.

Cables and plugs - check that the insulation is not damaged. This is a simple way to avoid a short circuit.
Fan - if it makes unusual noises, e.g. metallic clatter, this could indicate a problem with the bearings.
Fuses - It is always a good idea to have a spare to avoid downtime at the least opportune moment.

Professional service once a year

Just as a car needs regular maintenance, so does a oil heater should go in for servicing at least once a year - preferably before the season.

The service technician will check the pump pressure, the tightness of the fuel system, clean the nozzle and adjust the burner. This is a small cost compared to the losses associated with downtime or repairing a major breakdown.

How to store your heater in the off-season?

Heaters often stand unused for several months. It is worth ensuring that they are ready for use after a break.

Empty the fuel tankto avoid the formation of deposits.
Store the device in a dry, well-ventilated place, away from moisture.
Run a test run once every few weeksso that the mechanical components do not stagnate.

FAQ - Frequently asked questions about infrared oil heaters

Can fuel be left in the tank for the summer?
This is not recommended. Fuel loses its properties over time and forms deposits that can clog the filter. It is better to empty the tank and pour fresh fuel before the next season.

How often should I change the fuel filter?
Depending on the intensity of use - once a season is the minimum. In dusty conditions it is worth checking it more often.

Can the heater be operated in an enclosed room?
Yes, but provided there is adequate ventilation. The exhaust fumes must have an outlet so that they do not pose a danger to users. In EMLO workshop heaters, a tilted window is sufficient - in other words, natural ventilation. This is one of the important arguments for using our heaters - they do not require dedicated exhaust systems.

When to have the heater serviced?
Preferably before the heating season starts. Then the service technician can detect and rectify minor faults before they develop into more serious problems.

Infrared oil heaters are indispensable appliances in workshops, warehouses or on construction sites - provided that they are well maintained. Regular cleaning, fuel checks, fan inspection and annual servicing will ensure that the equipment will last for many years.

Looking after your heater is an investment in safety, fuel efficiency and uninterrupted operation.
