Electric heater EH3 is a compact and efficient 230 V heater for construction sites, renovation projects and other spaces that need temporary heating or drying. The efficient 800 m³/h airflow circulates air effectively. In addition, the built-in kWh meter makes it easy to track the unit’s energy consumption.

The EH3 suits heating, construction drying and air circulation alike. Warm air and a high airflow speed up the drying of structures and help even out the temperature across the whole space.

Who the Electric heater EH3 suits

The compact EH3 works well on construction sites, in renovation projects, apartments, warehouses and other spaces that need temporary heat or effective air circulation. Thanks to its IP44 enclosure, the unit also suits demanding conditions.

For example, you can use it during filler, painting and surface material work, for drying water damage, and for general temporary heating and better air circulation.

Electric heater EH3 – heating and drying

The EH3 has two power settings, 2.1 kW and 2.8 kW. At the lower setting, the heater runs on a 10 A fuse, and at the full 2.8 kW it needs a 16 A fuse.

You connect the heater to a standard 230 V mains supply. Therefore, it is easy to put to work on different site and renovation jobs.

The stepless 5–45 °C thermostat lets you set the temperature to suit the job. In addition, automatic overheating protection improves operating safety.

800 m³/h airflow speeds up drying

The 800 m³/h airflow of the Electric heater EH3 keeps the air moving effectively. This matters especially in construction drying, because good air circulation helps move moisture from structures into the surrounding air.

The top of the EH3 has four narrow air outlets that blow warm air in four directions. As a result, the heat spreads evenly, even in irregularly shaped spaces.

Built-in kWh meter for tracking energy use

A major advantage of the EH3 is its built-in energy meter. The kWh meter shows directly how much electrical energy the heater has used.

For example, this data makes it easier to monitor site energy use, allocate costs and document the actual energy consumption of the unit in rental use.

Choosing the right site heater

First, consider whether the site needs heating, drying or both. Then work out the output you need from the size of the space and the heating demand.

• Available supply: 230 V or 400 V
• Required heating or drying output
• Size of the space and need for air circulation
• Need for energy consumption tracking
• IP rating to match the operating environment

The EH3 meets these needs with a standard socket supply. For higher output or a 400 V supply, however, other temporary electric heating products are a better fit, such as the versatile TSR-EH18.

Safety

Place the heater on a stable, level surface so that air can circulate freely around it. Do not cover the air intake or outlet, because that reduces output and can trigger the overheating protection.

Check the supply cable and plug visually before each use. In addition, clean dust from the air intakes regularly so that the airflow and heating output stay unchanged.

Store the heater in a dry place when you do not use it. The compact design and light weight make it easy to move from one site to the next. A qualified electrician makes the electrical connections. You can read about the requirements for electrical work on the Tukes website.

Frequently asked questions

What is the difference between the 2.1 kW and 2.8 kW settings of the Electric heater EH3?

At the lower 2.1 kW setting, the heater runs on a 10 A fuse. The full 2.8 kW output needs a 16 A fuse and heats a larger space more effectively.

Can you also use the EH3 for drying?

Yes. Warm air and the 800 m³/h airflow together speed up the drying of structures. Therefore, the unit suits both heating and construction drying.

How does the kWh meter work?

The built-in kWh meter shows directly how much electrical energy the unit has used. For example, this helps you track energy use in rental use or allocate site costs.

Does the heater withstand site conditions?

Yes. The IP44 rating makes the unit suitable for demanding site conditions, and automatic overheating protection improves operating safety.
