New stainless steel heat exchanger
The Condensing KZT boiler is equipped with a new stainless steel heat exchanger which achieves better thermal efficiency and long service life.
Hot water always available with gas condensing boiler
Thanks to the PLUS function, the boiler always has a hot water supply ready that you can use immediately. The gas condensing boiler with a storage tank is able to satisfy high demands on DHW consumption and ensure the supply of hot water at the same time in various situations in the household.
Thanks to the 60L tank, it is possible to have a large amount of water ready for use, while the water contained in the tank is consumed, the boiler quickly heats the same amount that is stored in the tank.
Powerful control unit
Modern control electronics ensure high-quality and trouble-free operation in the Condensing KZT gas condensing boiler. It provides power regulation, self-diagnostics and detection of combustion errors. The control unit carefully analyses all these data and on the basis of them optimizes all factors that affect the overall efficiency of combustion.
Quality and efficiency
In the production of boilers we used brass components of the hydraulic assembly which ensures maximum reliability of the product. The new brass hydraulic group is equipped with:
- High-efficiency pump
- Three-way valve
- By-pass
- Flow regulator with filter
- Drain valve
Frost protection
To increase the service life we have integrated a function into the boiler that will prevent damage to your condensing boiler due to adverse freezing weather. If you leave the boiler connected to gas and electricity it will take care of everything for you. If the temperature drops below 6 °C the burner ignites itself and the pump switches on automatically.
Gas condensing boiler has protection against bacteria
We have incorporated a special Anti-Legionella function into the gas condensing boiler thanks to which you do not have to be afraid of the multiplying bacteria that like hot water. One of them is Legionella which is suitable for a water temperature of 25 – 55 °C.
The bacterium is destroyed by heating the water to more than 60 °C. The Anti-Legionella function will take care of heating the water in the DHW tank to 65 °C at least once a week for you regardless of your thermostat settings.
Comfortable operation
If you want to save even more with a gas condensing boiler and want to move the comfort bar even higher you can use an equithermal regulator * that allows you to do so. The controller will adjust the temperature according to the outdoor temperature.
The temperature will automatically adapt to changes at home and outside temperature. This method of regulation can make more efficient use of the boiler’s output and at the same time save you money on operation. In addition, you get more comfort because the controller will take care of everything for you.
However if you want even more convenience it will be provided with additional control with two-way OpenTherm communication.
* equithermal regulator is not part of the boiler delivery.
OpenTherm control (optional accessory)
The gas condensing boiler enables to connect OpenTherm control which can not only turn on the boiler but also to find out the difference between the actual room temperature and the set value. It enables modulation of the boiler output according to the thermal needs of the system. OpenTherm regulation guarantees lower consumption, more stable temperature and greater comfort for the user.
