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 impresses with its solid boiler body in a compact design. With a built-in electronic draft regulator, the combustion air is precisely controlled, 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 design according to the latest standards meets the requirements of BImSchV2 and has a CE declaration of conformity. Thanks to its flexibility and the easy control options for the boiler circuit pump as well as optional induced draft fans, the boiler can be optimally integrated into various heating circuit systems.
Expansion Vessel for Heating
The high-quality expansion vessel ensures reliable pressure compensation in your heating system. Available in sizes 80, 100, 140, and 200 liters, it can be flexibly adapted to the respective requirements of modern heating systems. The precise coordination of operating pressure, maximum flow temperature, and pre-charge pressure guarantees optimal operation.
With an operating pressure of 3 bar, a maximum flow temperature of 110°C, and a nitrogen pre-charge pressure of 1.5 bar, this expansion vessel offers long-term stability and is particularly easy to install thanks to the standardized 1" thread.
Buffer Tank without Heat Exchanger for Heating
The buffer tank serves as a hot water storage tank and enables the demand-based storage and release of heat. It is optimally matched to modern heating systems and is suitable for use in combination with pellet heating systems as well as with wood gasification or solid fuel boilers. The flexible design helps to efficiently cover the actual heat demand.
With a design caliber that requires at least 55 liters of buffer volume per kW of output for solid fuel boilers, the buffer tank offers a sustainable and crisis-proof solution for long-term heating needs. It can be used in all closed hot water heating systems and can also be easily adapted to various heat generators.
Connection package Defro Firewood
The Defro Firewood connection package includes all important components for a smooth and efficient connection of the gasification log wood boiler. High-quality connections such as return temperature control, boiler safety groups, and boiler fill and drain valves are combined to ensure safe operation.
Installation is made easier thanks to the included assembly instructions and hydraulic diagrams. The components are precisely dimensioned so that an energetically optimized connection to the heating system can be achieved and potential heat losses can be minimized.
Connection package buffer tank heating / solar – universal mounting set
This universal mounting set 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 remain where they are needed. All unused 1½" connections are effectively insulated, reducing heat loss to a minimum.
The easy installation of the set is supported by the included hydraulic example, which also allows less experienced installers to set it up quickly. In addition to the insulating plugs, the complete package includes a range of wall plugs, reducers, dirt traps, and ball valves that guarantee a secure connection and efficient operation.
