Attack KST Plus, 26 kW

Product detailed description

ATTACK CONDENSING KST 24
- wall mounted gas condensing boiler with instantaneous DHW heating
- power:

A compact and elegant boiler with intelligent control for your comfort. The ATTACK Condesing KST 24 is a wall hung condensing gas boiler ideal for heating with instantaneous hot water. The boiler achieves significant savings in gas consumption thanks to Smooth power modulation up to 1:10 and the Intelligent combustion system ISC can also operate with a minimum output from 3 - 30 kW, which is a great advantage for family homes. The boiler can also be controlled according to the outside temperature (equithermal control).

• Energy class for heating A
• Energy class for DHW A
• Preparation of hot water in an external storage tank
• Condensing heat exchanger stainless steel with extra wide water channels
• Compact and elegant design
• Ideal for smaller homes
• Easy to operate with high efficiency up to 106.4% and gas savings
• High modulation ratio 1:10
• Intelligent adaptive gas valve
• Mixed hydraulic group
• ICS (intelligent combustion system) guarantees perfect combustion in all conditions
• Safe and easy to use thanks to integrated protection functions
• Backlit LCD display with self-diagnostics and easy operation
• 6 Class NOx

New heat exchanger
The Condensing KST 24 gas boiler is equipped with a stainless steel heat exchanger featuring extra wide channels, where the inner part has been increased up to four times compared to the commonly used heat exchanger. Thanks to the new exchanger better thermal efficiency is achieved, better resistance to deposits which makes the Condensing KST 24 also ideal when replacing the boiler in an existing heating system.

Intelligent combustion system ISC
The Condensing KST 24 condensing boiler is equipped with an Intelligent combustion system. The only boiler on the market that adjusts its own parameters according to the current conditions using the Intelligent Combustion System. The Intelligent Combustion System controls the combustion and adjusts values such as gas flow to always achieve the correct air/gas ratio, ensuring:

• Reduction of gas consumption
• Lower CO2
emissions
• Shortened installation and boiler set-up time
• Modulation ratio 1:10
• Perfect combustion
• Extended boiler life
• Reduction of the number of off/on cycles
• Possibility to use the boiler for multiple gas types (G20 natural gas or G31 propane, fuel change and adjustment must be performed by an ATTACK service technician)

Quality and Efficiency
When manufacturing boilers we used brass components of the hydraulic assembly thus ensuring 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
• Hot water temperature sensor

Frost protection
To increase the service life, we have integrated a feature into the boiler to prevent damage to your condensing boiler due to adverse freezing weather. As long as you leave the boiler connected to gas and electricity, it takes care of everything for you. If the temperature drops below 6°C, the burner ignites itself and the pump automatically switches on.

Bacteria protection
We have incorporated a special Anti-Legionella function into the condensing boiler, so you don't have to worry about the multiplying bacteria that like warm water. One of them is Legionella, which is happy with a water temperature of 25 - 55 °C. Heating the water to more than 60 °C kills the bacterium. The Anti-Legionella function takes care of heating the water in the DHW tank to 65 °C at least once a week for you, regardless of your thermostat settings.

Pump blockage protection
During prolonged inactivity, dirt can build up in the pump, which could lead to blockage. That's why we have added a function to the boiler that makes sure the pump is clean, and if the pump is idle for 24 hours, the boiler will automatically switch it on for about 5 seconds to clean it.

Comfort Control
If you want to save even more with a condensing boiler and want to push the comfort bar even higher, you can use the equithermal controller* to make it possible. The controller will adjust the temperature according to the outside temperature. The temperature will then automatically adjust to changes in the home and the outside temperature. This method of control can make more efficient use of the boiler's output and also saves you money on running costs. In addition, you get more comfort because the controller takes care of everything for you.

* The equithermic controller is not included with the boiler.
