TEZA - Thermal device
Manufactured and certified in Slovakia since 2010
Certified product TEZA 2000 - is suitable for floor heating and radiators. The device has a very low power consumption of only 2 kWh and the current consumption is less than 9 A. Therefore, our device is at least 30% more economical compared to traditional electric boilers. One unit of TEZA 2000 can heat an area of approximately 60 m2. If you want to heat a larger area, you can simply add another TEZA 2000 to the series. By combining two TEZA 2000 devices, you can heat an area of up to 120 m2 with floor heating. This device is also ideal for connecting to solar panels, heat pumps, solar collectors, boilers, fireplaces, and other systems.

Thermal devices TEZA 2000 are characterized by reliability and trouble-free operation and exceed the lifespan of boilers several times. In case the thermal device still stops functioning, for example, due to a lack of water, etc., we will ensure the service of these thermal devices so that you send us the non-functional device, for example by post (recommended), and we will repair it as soon as possible. If it is a non-warranty service, the total cost of repairing the thermal device represents half of the purchase price of a new thermal device.
Our device was designed as a compact unit that effectively achieves rapid heating. The flowing water immediately cools the device, while the thermal energy is transferred to the system without losses. This innovative approach ensures even temperature distribution between all radiators, resulting in optimal heating with minimal heat losses.
During operation, our device maintains a stable temperature, which means that on radiators or in floor heating systems, it reaches a higher temperature than the water returning to the device. For example, when the temperature in the device is 50 °C, the temperature in the radiators reaches 55 °C, ensuring an effective and comfortable heating system.
This is not a trick, but a combination of electricity and physics. When you put a liter of water in a kettle, it boils in 3 minutes. But you can keep your hand in the water for 20 minutes. It's based on this principle. The thermal device does not heat the water, it is designed to heat up quickly and the water flowing through it cools it down. Radiators are like heating bodies. This also applies to floor heating. Therefore, the water in the radiators is always warmer than on the heating device itself. It is warm like the return. The goal is to heat the water in the radiators as quickly as possible. So if I heat it with 6 kW and suitable impulses that must correspond to this system and precise setting, I have 50% lower consumption and the water in the radiators moves around 54 °C.
TEZA 2000 is a new thermal device that works on the basis of heating circulating water with a unique internal system that can more effectively deliver the produced heat to radiators or floor heating.
The thermal device is never warmer than the radiators or floor heating - perfect temperature distribution throughout the system.
The new thermal device TEZA 2000 is intended for heating rooms, apartments, houses, offices, cottages, garages, etc. In the heating system with TEZA 2000 devices, we recommend using steel panel and rib radiators, and for floor heating, this system is ideal. For this device, it is necessary to use radiators corresponding to the performance of the given room and their dimensions. The thermal device TEZA 2000 is the most economical, safest, most reliable, and simplest heating solution. The heating costs are comparable to gas boiler heating. This system can be combined with other heat sources. A great advantage is that for the installation of thermal devices, we only need 10 A. TEZA 2000 has very small dimensions. Heating with the TEZA 2000 device is ideal for low-energy houses.
You can see the thermal device TEZA 2000 installed, for example: Penzión Kamzík Stredisková 360/1 Lieskovec u Zvolena, Suveníry shop námestie Bardejov, Mešťanská piváreň Jozefa Vuruma 115/10 Žilina or info also at Mešťanská Piváreň Mariánské námestie 195/10 Žilina. We presented the thermal device TEZA 2000 at the AQUA-THERM Nitra 2012 exhibition, where there was great interest in this heating system, see: Aqua-therm 2012 - it impressed us.

EVERYTHING PROBLEM-FREE AND FUNCTIONAL!!!
A:
We performed a test in a garage with a metal gate and a size of 30m2. The outside temperature was -5°C and in the garage it was 0°C. We put a 2kW direct heater in the garage and let it run for 10 hours. After these 10 hours, we measured a temperature of 7°C in the garage. We let the garage cool down to have the same conditions and put one TEZA®2000 device in it, to which we connected two 1m steel radiators Korad 22k 6/10. After 10 hours, the temperature on the radiators was 58°C and in the garage 15°C, which proves that the direct heater with a consumption of 2kWh heated this garage by half less than when we used a device that also consumes 2 kWh and connected two 1m radiators to it. The temperature in the garage was higher by 50% with the same consumption of 2kWh and under the same conditions with the TEZA®2000 device.
B:
Tested in an uninsulated building with an area of 110 m2, 5 radiators with a total length of 5 m, temperature 24 °C, average consumption 2.75 kWh, which is enough for an insulated house with an area of approximately 100 m2. To achieve the same performance, heat exchangers with a power of 7 kW are used. Money like for wood, but no work. Confirmed by buyers. A man to whom I installed this system 8 years ago in Hodonín in a 170m2 house, floor + radiators, uses only 2 heating devices, told me that when he turns on the third, he has 27°C in the house. When we met after two years, he told me literally: "I don't know what's in it, but I save 30,000,- CZK per year".
He used to use a 12 kW electric boiler, now he has a power consumption of just over 2 kWh and the heat is pleasant. His words!!! Unfortunately, it's true, even if critics don't like it. But no one can change it. Tested for 8 years. Almost 2000 pieces of heating devices sold. Those who have this system and installed it correctly do not complain. On the contrary. The interest of buyers who want to heat cheaply and ecologically pleases me, I don't impose my system on critics. The production and sale of this system do not make a living for me, it's just my hobby, which I've been improving for 12 years to make it better and more efficient :)
C:
During our tests, we found that one 2kWh device heats four 1m radiators to a temperature of 40 °C. If we put two devices in series and run them simultaneously for 15 minutes, so that they turn on for 15 minutes and turn off for 15 minutes, the temperature on the radiators ranges from 43 °C to 52 °C and the energy consumption is the same as if one device were in operation. The temperature rises by 15 °C in 15 minutes, but cools down by only half, 7 °C - 8 °C, in the same time. The thermal performance has increased and the energy consumption has remained the same, so in the end, if we heat 4 rooms, we have a lower energy consumption than 2 kWh in this case. We only run these devices in stronger frosts.
