Defro Firewood complete package 15 kW plus buffer tank without heat exchanger

Defro Firewood Plus 15 kW – modern natural draft boiler

The Defro Firewood Plus 15 kW natural draft boiler It impresses with its solid boiler body and compact design. A built-in electronic flue regulator precisely controls the combustion air, resulting in economical and safe operation. The innovative design, with a factory-integrated safety heat exchanger and sight glass, also allows for easy visual monitoring of combustion.

The state-of-the-art design meets the requirements of the Federal Immission Control Ordinance (BImSchV2) and carries a CE declaration of conformity. Thanks to its flexibility and easy control of the boiler circuit pump and optional induced draft fans, the boiler can be optimally integrated into various heating circuit systems.

Expansion tank for heating

This high-quality expansion tank ensures reliable pressure equalization in your heating system. Available in 80, 100, 140, and 200-liter sizes, it can be flexibly adapted to the specific requirements of modern heating systems. The precise coordination of operating pressure, maximum flow temperature, and pre-pressure guarantees optimal operation.

With an operating pressure of 3 bar, a maximum flow temperature of 110°C and a pre-pressure in the nitrogen range of 1.5 bar, this expansion vessel offers permanent stability and is thanks to the standardized 1"-Thread particularly easy to install.

Buffer storage without heat exchanger for heating

The buffer tank serves as a hot water storage unit and enables the storage and release of heat as needed. It is optimally adapted to modern heating systems and is suitable for use in combination with pellet heating systems as well as wood gasification or solid fuel boilers. Its flexible design helps to efficiently meet actual heat requirements.

With a design caliber that Solid fuel boilersRequiring at least 55 liters of buffer volume per kW of power, the buffer storage tank offers a sustainable and crisis-proof solution for long-term heating needs. It can be used in all closed-loop hot water heating systems and can also be easily adapted to various heat generators.

Defro Firewood connection package

The Defro Firewood connection package includes all the important components for a smooth and efficient connection of the carburettor-Log boilers. High-quality connections such as return temperature boosters, boiler safety groups and boiler filling and draining valves are combined to ensure safe operation.

The included assembly instructions and hydraulic diagrams simplify installation. The components are precisely dimensioned to ensure optimal energy efficiency and minimize potential heat loss.

Connection package buffer storage heating/solar – universal mounting set

This universal mounting kit enables the efficient connection of a buffer tank to your heating or solar system. Thanks to the innovative connection package insulation, the generated heat and energy stay where they're needed. All unused 1.5" connections are effectively insulated, reducing heat loss to a minimum.

The easy installation of the set is supported by the included hydraulic example, which allows even less experienced installers to assemble it quickly.In addition to the insulating plugs, the complete package includes a range of dowels, reducers, strainers and ball valves that guarantee a secure connection and efficient operation.
