Is a 3 kW electric heater enough for a garage or workshop?

A 3 kW electric heater with a PTC heating element (an element with a positive temperature coefficient, whose resistance rises with temperature), such as the Toolsa TA-ER3C, has a maximum power of 3000 W and moves 365 m³/h of air, giving a strong stream of heat in a garage, workshop or industrial plant; the manufacturer quotes 5 seconds from switch-on to the first heat. The first setting delivers 1500 W when the full 3000 W is not needed. The heater is for indoor use only, on a flat surface, away from flammable, explosive and damp environments. The full range of models is on the electric air heaters page.

How much electricity does a 3 kW fan heater use?

A 3 kW fan heater on its second setting draws 3000 W, which is 3 kWh per hour of operation, and on the first setting it draws 1500 W, which is 1.5 kWh per hour. The thermostat switches the heating off once the set temperature is reached, so with the thermostat in use average consumption can be lower than with continuous heating. A 3000 W load is demanding for an installation: the manual of the Toolsa TA-ER3C requires you to assess the capacity of the meter, cable and socket before starting and to use a 15 A three-wire socket. To estimate the hourly cost, multiply the kWh by the tariff per kWh from your bill.

How loud is the Toolsa TA-ER3C?

The Toolsa TA-ER3C has a noise level of 45 dB, and the manufacturer's manual describes the noise emission of these heaters as low. Airflow is 365 m³/h, and the unit's footprint is 275 × 175 × 318 mm. The manufacturer also states that the heater produces no exhaust fumes or unpleasant odours, which is why an electric fan heater suits rooms where people work or stay for long periods.

How do the knobs and the two heat settings (1500 W and 3000 W) work?

The Toolsa TA-ER3C has two knobs: the mode knob on the left and the temperature knob on the right. Besides the OFF position, the mode knob has three settings: fan only (the heating stays off), a first heat setting of 1500 W and a second heat setting of 3000 W. The temperature knob, with a range of 0–40 °C when the surroundings are at 0 °C, sets the point at which the thermostat switches the heating off; the fan keeps running, and the heating switches on again when the temperature drops. The POWER indicator shows that the heater is connected to the mains.

Why does the heating switch off during operation?

The heating can switch off for two reasons, and the first is normal operation. The thermostat, which keeps the set temperature, switches the heating off when that temperature is reached, the fan keeps running, and when the temperature falls the heater starts heating again. The second reason is the thermal cut-out with automatic reset, which monitors the temperature at the outlet and prevents overheating caused by incorrect use, for example a blocked inlet or outlet. In that case switch the heater off, disconnect the power, wait for it to cool and find the cause before starting it again.

Can a 3 kW fan heater be used with a timer, and how should it be switched off?

The Toolsa TA-ER3C must not be used with a programmer, a timer or any other device that could switch it on automatically, because this creates a fire risk. Switching off after use is manual: when heating is finished, move the selector to cold air and let it run for 3–5 minutes; only then switch the heater off completely and disconnect the mains cable. The air inlet and outlet must not be covered while the heater is running.

How does the TA-ER3C compare with the TA-ER2C and TA-ES3?

The Toolsa TA-ER3C combines a maximum power of 3000 W with a noise level of 45 dB, and its fan moves 365 m³/h of air; its dimensions are 275 × 175 × 318 mm. The smaller Toolsa TA-ER2C delivers 2000 W and 250 m³/h in a body of 218 × 140 × 250 mm, so it offers 1000 W less power. The Toolsa TA-ES3 has the same maximum power of 3000 W, but airflow of 280 m³/h, a noise level of 46 dB and a larger body of 290 × 253 × 403 mm. The strongest airflow of the three is therefore delivered by the TA-ER3C.

Can an electric fan heater work as a fan only?

The mode knob of the Toolsa TA-ER3C has a fan-only position in which only the fan runs and the heating element stays off. The unit then moves air without warming it, so it can also be used outside the heating season. The same position is used to cool the heater after use: the manufacturer recommends running it on cold air for 3–5 minutes before switching it off.
