Ecosy+ Revolution 21 Multi-Fuel / Wood Burning BOILER Stove - Eco Design Approved

About the Stove

" The first Eco Design Boiler stove to be approved in an official UK test facility " 

Designed by our UK brand Ecosy+ the Revolution 21 Eco Design, DEFRA-approved Boiler Stove, is a powerful and efficient heating solution that’s perfect for those looking to reduce heating bills with the focal point of their home. Designed to heat both your room and central heating system, this stove can supply up to 11kW to the water ( which equates to around 8-9 single radiators ) and a whopping 10kW  to the room itself, providing abundant warmth and comfort to your entire home. With an outstanding efficiency rating of over 77%, it maximizes heat output while keeping fuel consumption low, making it ideal for those who are buying in their fuel and producing their own. For added versatility, the optional multi-fuel grate allows you to burn smokeless coal as well. Featuring a durable cast iron door and a large glass window—kept clear by an advanced air wash system—this stove is not only highly functional but also stylish. DEFRA-approved for use in smoke-controlled areas, the Revolution 21 offers unmatched performance, flexibility, and eco-conscious heating for your home.

Revolution 21 is packed with standout features for ease of use and efficiency. Its cool-to-touch chrome handle is ideal for day-to-day operation, ensuring safe and comfortable handling of the door. The extra tall cast iron log guard prevents logs from rolling out onto the hearth, while allowing them to naturally roll back into the fire for improved safety and combustion. The innovative slow burn control and fully insulated vermiculite brick lining allow you to bank the stove up for long, sustained burns—perfect for those chilly winter days when continuous warmth is needed. Other highlights include the stove’s ceramic glass window, offering a beautiful view of the fire, and an advanced air wash system that keeps the glass clean for a clear and mesmerizing flame display.  

Boiler Specification

Note: Our expertise focusses around the use of the stove itself and associated chimney parts. Technical questions in relation to the plumbing side, may need to be put to a qualified plumber.  Please see all technical information for the boiler itself below.

• The stove can supply a maximum of 11kw (37,554 BTU) to the central heating and hot water systems as well as 10kw (34,140 BTU) directly to the room. Your radiator requirements will be measured in BTU. To calculate the needed heat output, add up the BTU requirement of each radiator in the house. (1kw = approx 3,500 BTU.) (  Exact heat output will always depend on the volume / quality of the fuel burnt and the type of system it is plumbed into - Dry seasoned hardwood, or smokeless coal are the best to maintain high outputs to the boiler
• Suitable for open vented systems only (Not suitable for pressurised systems) 
• The boiler has 4 x 1" threaded outlets at the rear. 2 are for flow and 2 are for return. Depending on the system, you could diagonally cap off 1 flow and 1 return outlet, if they are not required. 
• Pressure - 2 bar ( 1bar = 100kpa)
• Boiler Water Capacity - 10.5l

Clean Burn System

The Revolution 21 has an advanced secondary clean burn system that is controled by a chrome pull lever on the base of the stove. This lever opens and closes a vent that pulls air over the fire, re burning the initial smoke emitted by the stove. This makes the stove a lot more efficient and eco friendly saving you a large amount in fuel costs.
