Buffer tanks efficiently collect, store, and transfer excess hot water from multiple heat sources, including pellet boilers, heat pumps, water-jacket fireplaces, and coal boilers. Acting as a safeguard for central heating systems, they balance the thermal power of heating devices and the system's demand.

Insulated with polystyrene foam and encased in durable plastic, our buffers offer exceptional energy efficiency. Available in both wall-mounted and standing models, KHT Group provides capacities from 60 to 2000 liters to suit various needs.

The buffer functions like the body's fat reserves, storing surplus energy to meet increased demand during peak periods, ensuring consistent and efficient heating performance.

The KHT-Streamfire pellet boilers are state-of-the-art heating solutions that seamlessly integrate efficiency, cost-effectiveness, and environmental sustainability. These systems provide optimal comfort for heating both residential and commercial buildings, while maintaining a strong commitment to environmental preservation. With superior build quality, user-friendly operation, and cutting-edge technical features, they represent the ideal choice for those seeking a high-performance, eco-friendly heating solution.

The advanced burner technology incorporated in our boilers requires no tools for maintenance, such as replacing the igniter or photocell.

The maintenance of the burner is straightforward and can be completed in under 10 minutes. Removing the burner does not necessitate detaching it from the front door of the boiler. The innovative clamp system enables the burner to be detached in less than three minutes.

We offer two types of controllers: the KEY brand controller and the Bragger controller.

The boiler design, with the storage tank mounted above the heat exchanger, allows for installation in the majority of boiler rooms.

Our boilers are listed on the ZUM registry.

Available boiler capacities: 10 kW, 15 kW, 20 kW.

STREAMFIRE BOILER EFFICIENCY CLASS - A+

Hygienic tanks efficiently connect to buffer systems, delivering domestic hot water via a high-performance, flexible corrugated stainless-steel coil. This design ensures rapid heating, excellent flow-through capacity, and hygiene certification across all tank sizes.

The corrugated coil's advanced structure provides superior heat exchange compared to standard round coils. Multiple heat sources can be integrated, such as water-jacket fireplaces, coal or gas boilers, and heat pumps. Robust insulation minimizes heat loss, ensuring optimal efficiency.

Available variants:

• HPh-10: One hygienic coil
• HPh-11: One hygienic coil + one heat source coil
• HPh-12: One hygienic coil + two heat source coils
• HPh-20: Two hygienic coils

Coil heat exchangers are a reliable solution for providing hot water, compatible with a single heat source such as gas, pellet, or oil boilers, and water-jacket fireplaces. Water is efficiently heated by a spiral coil positioned in the lower or upper sections of the tank.

Enamelled heat exchangers are available in multiple variants:

• BTm: Maxi coil optimized for heat pumps
• BT-11: Two coils for solar panels and central heating boilers
• BT-01: Single coil
• BT-00: Coil-free design
