Suitable fuels
4 Suitable fuels
Suitable fuel
The firewood must be air-dry, i.e. it must have dried for
at least one year and have a water content under 20%.
We recommend using half-metre split logs with an
average diameter of 10 cm.
Do not split round logs with a diameter under 8 cm;
instead place them between the split logs in the
middle.
Boards may only be added between the logs and in no
case should they be included in the first layer as they
would block the burn-through opening in the grate.
Small pieces of fuel may only be burned as a minor
addition placed among the split logs, but never in the
bottom layer. The smaller the pieces, the less of them
may be added.
Wood briquettes measuring 6 cm to 10 cm in diameter
in compliance with ISO 17225-3:2014.
Only 1 oversized split log or 1 stump piece can be
placed in the top layer, but no more. Complete
burning may require 2 combustion phases.
Unsuitable fuel
Wet fuel with a moisture content in excess of 20% may
not be burned as it results in condensation which can
lead to corrosion of the boiler's fuel chamber walls.
The following also may not be burned: rubbish, paper
and cardboard (only for start-up), wood dust from
sanding, sawdust, pieces of wood smaller than thumb-
sized, coal and coke, and fuels generally prohibited by
local air quality regulations, such as old railway
sleepers, plastic-coated plywood, impregnated wood,
etc.
The Clean Air Act 1993 and Smoke Control Areas
Under the Clean Air Act local authorities may declare
the whole or part of the district of the authority to be a
smoke control area. It is an offence to emit smoke from
a chimney of a building, from a furnace or from any
fixed boiler if located in a designated smoke control
area. It is also an offence to acquire an "unauthorised
fuel" for use within a smoke control area unless it is
used in an "exempt" appliance ("exempted" from the
controls which generally apply in the smoke control
area).
In England appliances are exempted by publication on
a list by the Secretary of State in accordance with
changes made to sections 20 and 21 of the Clean Air
Act 1993 by section 15 of the Deregulation Act 2015.
Similarly in Scotland appliances are exempted by
publication on a list by Scottish Ministers under section
50 of the Regulatory Reform (Scotland) Act 2014.
In Wales and Northern Ireland these are authorised by
regulations made by Welsh Ministers and by the
Department of the Environment respectively.
The ETA SH 20, 30, 40, 50 and 60 kW boiler has been
recommended as suitable for use in smoke control
areas when burning air-dried billet wood (max. 20%
water content).

Air Act can be found here:

Your local authority is responsible for implementing the
Clean Air Act 1993 including designation and
supervision of smoke control areas and you can
contact them for details of Clean Air Act requirements.
