With Schiedel you can be energy efficient and enjoy a real fire. The combination of advanced chimney technology and efficient wood burning appliances can give you the best of both worlds - an energy efficient home and the enjoyment of a real fire.

The Schiedel Energy Efficient solutions are designed to work with modern efficient appliances. The superior insulation in the chimney allows flue gases to escape freely to the atmosphere even at low temperatures.

Advanced chimney technology in action. Suitable for stoves, inserts and pellet boilers in masonry and timber frame construction.

What does Energy Efficiency & Document L mean for you?
In the drive for more efficient homes the latest revision of the Document L building regulation means that all new build developments must comply with stringent new rules, aimed at reducing carbon emissions from houses by 20%. By choosing an appropriate secondary heating appliance and an efficient chimney/flue system, you can help meet the Government’s target without compromising on the cosy focal point that truly makes a house a home.

Lower your carbon count
Document L assumes two types of heating - primary central heating and secondary heating from room heaters. The SAP calculation used to determine the carbon emissions assumes the secondary heating to be electric.

Electricity is a more carbon intensive energy source than wood, dual fuel (a mix of wood and solid fuel), gas or oil. This fact gives you the opportunity to make a carbon saving by substituting electricity with another fuel and an efficient appliance, open or glass fronted. By using a carbon efficient secondary heat source you can gain carbon credits to offset against other aspects of construction like insulation or glazing.

Chimney specification
The carbon saving can be increased further by using a chimney that has a diameter of less than 200mm or one with a damper as this halves the assumed air flow in the chimney. Most modern appliances can work efficiently with a properly insulated chimney of less than 200mm. It is important to note that there is no benefit in using a flueless appliance, as the air flow will be assumed to be the same as a 200mm chimney.

Choosing your appliance at the planning stage is now crucial
Both primary and secondary heating MUST be specified at the design stage if the required carbon savings are to be realised. This is a big change in our thinking as the choice of appliance would usually have been left until building was complete or the house occupied. If the choice is not made before the build, the SAP programme will default to the worst case scenario.
