1. SpeedComfort Heizkörperverstärker
The SpeedComfort heater fan improves the heat output of radiators and can double heating performance, resulting in savings of up to 22% on gas costs. With better heat distribution, the temperature in the room rises faster and more evenly, without disturbing the peace. Installation is simple, and the device operates energy-efficiently, consuming no power in standby mode and only 0.55 kWh per year during operation. An automatic temperature sensor controls the operation based on the radiator temperature. The Dutch company behind SpeedComfort aims to reduce CO2 emissions through intelligent heating and make households more energy-efficient.

2. SpeedComfort 2.0 Duo set radiator booster 50-120 cm
The intelligent radiator fan with up to 22% energy savings. SpeedComfort provides radiators with more power and accelerates convection. This way, you get more heat from your radiators, the room warms up much faster, and a better heat distribution is created. As a result, the thermostat turns off more quickly, and the water temperature of your boiler can be lowered. This saves energy. The Basic Duo Set is the ideal starter kit if you have a standard radiator that is between 75 and 120 cm long. The set includes two SpeedComforts, an adapter, and a smart thermostat sensor that automatically turns the SpeedComforts on or off.
SpeedComfort Starter Set Duo:
Smart radiator booster fan for heaters with a minimum plate gap of 70 mm for mounting under the radiator. Depending on the length of your radiator or convector, you can attach multiple SpeedComforts to your heating system. In an average-sized living room, you will need about 3 to 5 SpeedComforts. With the included 30 cm connection cables, additional SpeedComforts can be connected.
How the radiator fan works:
Through enhanced air circulation and improved heat distribution, a pleasant and even room climate is created about twice as fast in your home, ensuring greater living comfort. The energy-efficient radiator fan improves air circulation in the room through its blower, thereby increasing heating performance. This allows you to use your energy supply more efficiently and significantly reduce your heating costs. Once installed, you can enjoy worry-free. The SpeedComforts are automatically turned on and off. This is managed by the smart sensor, which is not visible behind the control panel. Due to the lossless adapter, the SpeedComforts consume no power when turned off.

3. SpeedComfort Mono set
Description
The intelligent radiator fan with up to 22% energy savings.
SpeedComfort provides radiators with more power and accelerates convection. This way, you receive more heat from your radiators, the room warms up much faster, and better heat distribution is achieved. As a result, the thermostat switches off more quickly, and the water temperature of your boiler can be lowered. This saves energy.
The Basic Mono Set is the ideal starter kit or expansion set if you have a small standard radiator. The set includes one SpeedComfort, an adapter, and an intelligent thermostat sensor that automatically turns the SpeedComforts on or off.
SpeedComfort Starter Set Mono:

4. SpeedComfort 2.0 Extension set radiator amplifier
The intelligent radiator fan with up to 22% energy savings.
SpeedComfort provides more performance to radiators and accelerates convection. This way, you receive more heat from your radiators, the room warms up much faster, and a better heat distribution is created. As a result, the thermostat turns off more quickly, and the water temperature of your boiler can be lowered. This saves energy.
The Basic extension set consists of an additional SpeedComfort without power supply and sensor, but with a connection cable. The SpeedComfort can be used as an addition to a starter set for very long radiators. With a 30 cm long connection cable, you can easily connect multiple SpeedComforts together without needing an additional adapter.
Functionality of the radiator fan:
Through enhanced air circulation and improved heat distribution, a pleasant and even room climate in your home is created about twice as quickly, providing more living comfort. The energy-efficient radiator fan improves air circulation in the room with its blower, thus increasing heating performance. This allows you to use your energy supply more efficiently and significantly reduce your heating costs. Install it once, then enjoy worry-free! The SpeedComforts are automatically turned on and off, managed by the intelligent sensor. Due to the lossless adapter, the SpeedComforts consume no power when turned off. When turned on, they consume very little energy: only 0.55 kWh per SpeedComfort per year. In short: you install SpeedComfort and no longer have to pay attention to it.
Features
Support feet for convector radiators and single plate for flat and narrow radiators.

9. H-Tronic H Tronic HTS 1000
Based on this measured value, a variety of temperature controls can be implemented using 3 different functions (thermometer, cooling and heating). Various consumers (e.g. fan heaters, air conditioners, alarm systems, etc.) can be directly controlled automatically and manually via two integrated, potential-free relays. A clear OLED display provides constant (or time-limited) information about the current temperature, selected function and current switching status of the integrated relays.EXAMPLES OF USE:Replacement for defective thermostats in heating systems, as a replacement control for air conditioning systems, for monitoring and controlling temperatures, e.g. in the production of beers and spirits or in greenhouses for temperature-controlled ventilation.
