For supplemental heating, an electric heater with adjustable power and a thermostat is the most economical choice, as it allows you to heat only that one room to the exact desired temperature, rather than firing up the entire central heating system for a single space. Ceramic, infrared, or halogen heaters react quickly and consume relatively little power for short, targeted heating, whereas a heater without a thermostat often continues to run at full power for unnecessarily long periods. A model such as the Dynter HW2002, with an adjustable power range of 1500 to 2000 watts and a thermostat, lets you control consumption yourself.
What determines if a heater is economical?
Three factors combined determine how economical an electric heater is in practice: the power in watts, the presence of a thermostat, and how targeted the heat output is. Higher power warms a room faster, but also costs more per hour. A thermostat ensures that the heater switches itself off as soon as the set temperature is reached, preventing you from heating unnecessarily. Targeted heating techniques, such as infrared, radiate heat directly to people and surfaces instead of heating the entire volume of air first, which can save energy during short-term use.
Electric heater with thermostat vs. without thermostat
A heater without a thermostat runs at a fixed power setting as long as it is on, even when the room is already at the desired temperature. This means you have to manually switch it on and off to prevent the room from becoming unnecessarily hot and wasting electricity. A heater with a thermostat, such as the HW2002, measures the room temperature and automatically switches between power levels or standby as soon as the set level is reached. In practice, this makes a noticeable difference in total energy consumption, especially if you use the heater for longer periods.
Ceramic heater vs. halogen or infrared heater
A ceramic heater warms the air in the room relatively quickly via a ceramic heating element and a fan, making it suitable for making small to medium-sized rooms comfortable within minutes. A halogen or infrared heater primarily warms objects and people directly in the path of the radiation, which is efficient if you are sitting in one spot, such as at a desk, but is less suitable for evenly heating an entire room. For general supplemental heating of a room, a ceramic heater with a thermostat is usually the more practical and economical choice.
When is supplemental heating with an electric heater more advantageous than the central heating boiler?
Supplemental heating with an electric heater pays off especially when you only want to heat one room briefly and in a targeted manner, for example, a home office during the day or the bathroom in the morning, while the rest of the house does not need to be actively heated. The central heating boiler often heats the entire home or at least a large part of it via radiators, which is less efficient if you are only in one room. For the structural heating of an entire home throughout the day, the central heating system is generally more cost-effective, as electric heating is more expensive per unit of heat generated than gas.
How much does an electric heater cost per hour of use?
At an average electricity rate of around €0.30 per kWh, a heater at its highest setting of 2000 watts costs approximately €0.60 per hour, and at its lowest setting of 1500 watts, approximately €0.45 per hour. Thanks to the thermostat of the HW2002, the unit does not actually run continuously at full power in practice, which often results in lower average consumption and therefore lower hourly costs than this maximum calculation. Please note that the exact rate and thus the hourly cost may vary per energy contract.
Tips for using a heater as economically as possible
Do not set the thermostat higher than necessary; every extra degree costs noticeably more energy. Use the heater in a targeted way in the room where you are actually sitting, rather than heating multiple rooms simultaneously. Close doors to limit heat loss to other rooms, and possibly combine supplemental heating with a lower setting on the central heating thermostat in the rest of the house. This way, you benefit from fast, targeted comfort without unnecessarily burdening your energy bill.
Quick answer: an electric heater with adjustable power and a built-in thermostat, such as the Dynter HW2002, is the most economical for targeted supplemental heating of one room, as it allows you to heat only what is necessary without firing up the entire central heating system.

Frequently asked questions
Is supplemental heating with an electric heater more expensive than the central heating boiler?
For brief and targeted heating of one room, an electric heater is often more advantageous, but for the structural heating of the entire home, the central heating boiler remains generally cheaper per unit of heat generated.
What heater power do I need per m²?
As a rule of thumb, count on approximately 60 to 100 watts per square meter for a normally insulated room; an adjustable heater like the HW2002 therefore covers most rooms in the house.
Is a heater with a thermostat really more economical?
Yes, because the heater switches itself off or down as soon as the set temperature is reached, rather than continuing to run at full power.
Can you leave an electric heater on all day?
You can with a heater equipped with a thermostat and overheat protection, but never leave a heater running unattended without supervision in the room.
What does an electric heater cost per hour?
At a rate of around €0.30 per kWh, a 2000-watt heater at full power costs approximately €0.60 per hour; with a thermostat, average consumption in practice is often lower.
Is a ceramic heater safer than a halogen heater?
Both types are safe under normal use provided they are equipped with tilt protection and overheat protection; a ceramic heater generally does not have a glowing visible element, which reduces the risk of burns upon contact.
