 - Wood Heater - How it Heats
Reliability and efficiency lie at the heart of the Rayburn
concept. Designed by engineers and hand built by craftsmen,
the Rayburn delivers assured performance year after year.
Around the country thousands of homes depend upon Rayburn
for central heating, domestic hot water and cooking. It is
a combination of `a good product well made` and the use of
the very latest technology that help the Rayburn perform
so well.
A clean burning, wood fired Rayburn uses indirect heat technology to create a stable, controllable heat source. Heat is transferred from the fire to the heavy, heat retentive castings by the radiation, the top of the oven being heated by flue gases passing over it. A unique triangular box under the oven reflects upwards to distribute heat across the floor of the oven. Inside, a special convector duct ensures that heat is conveyed to all parts evenly.
In a Rayburn, there are no oven flues to become blocked that could mean weekly cleaning as with some other wood burning cookers. There's little residual soot or dust, just the combustion gases being utilised to the full before being released cleanly via the chimney.
Mounted into the top of a Rayburn is a large, cast-iron hotplate, underneath which are deep fins angled directly above the fire to collect and concentrate the heat. The heat is then graduated across the hotplate from left to right. The hotter left side being perfect for fast stir-frys and quick boiling - just slide across to simmer. And, as many a Rayburn enthusiast will confirm, its superb built-in griddle makes it perfect for toast, toasted sandwiches and pancakes etc.
Firebox
For best results use a mixture of soft and hard woods. Dry soft woods give a quick, hot fire to bring the cooker quickly up to temperature after idling. Burn hard woods for more prolonged burning once a desired temperature has been reached or for through the night. |
Spinwheel
This controls the amount of air to the fire. The more open the higher the burn - adjust to set the fire at the stable level. For overnight banking, the spinwheel should be turned until it is almost closed so that the fire burns low and slow. |
Hotwater
With all four water heating Rayburns, domestic hot water is provided 24 hours, completely automatically with no attention necessary. Some models can be adjusted seasonally to limit the output as required therefore conserving fuel. |
Thermostat
This simple control is fitted to the 345W and the 355SFW to allow the temperature circulating through the radiators to be adjusted. It automatically adjusts the air flow to the fire working in conjunction with the central heating thermostats to maintain a constant temperature. |
There's more to discover, controls to tweak to set your Rayburn just so - the Chimney Damper, Flue Dilution Lever, Secondary Air Slide, Priority Damper - all there to provide maximum flexibility, performance and economy. But finding out is half the pleasure as you learn to enjoy life more with your Rayburn.

1.
The Hotplate
A solid one-piece cast iron construction, with heat graduated
along its length. Just like a professional chef`s Hotplate,
pans are simply slid from simmer to boiling, or any temperature
in between, eradicating the need to be constantly handling
controls and glancing under pans. Hotplate heat can be adjusted,
and larger models will accommodate up to five saucepans.
A useful integral pan stand is an additional feature of Power
Flue Cookmasters.
2. Heat Source/Burner Unit
Different models have different types of burners, from the
traditional continuous burning Rayburn to advanced high
power units which allow on/off operation.
3. Insulated Lids
The characteristic insulated lids are a stylish feature of
the true range. When in the closed position they retain
Hotplate heat, leaving the highly polished finish warm
to the touch.
4. Main Oven
Another authentic range feature is the Rayburns cast iron
main oven. All models include this large oven, which is
ideal for all types of cooking, baking roasting and slow
cooking. Being made from cast iron and using indirect heat,
the oven can cook in the gentle way that is unique to a
real range. A thermodial in the main oven door shows a
guide to the centre oven temperature.
5. Lower Oven
Models featuring a cast iron lower oven operate at half the
main oven temperature; sheet metal versions maintain heat
at one third of the main oven settings. |

2. Heat Source/Burner Unit
The heart of the Rayburn. Different types of burners are
available, from the traditional continuous burning Rayburn
or the modern technology of powerful burners allowing intermittent
on/off operation. Gas and oil central heating models generally
have two burners, and most have an integral programmer.
