Rayburn - Cookers

You are here: Home > Range Cookers > Rayburn

For over fifty years, the Rayburn has been the warm heart of many homes, supplying hot water, running the central heating - and, of course, creating the controllable heat that makes them such a joy to work with.

There are three types of Rayburn to choose from:

The Rayburn Cookmaster
is a family-sized two oven range cooker that gives you a flexible choice of cooking methods

The Rayburn Cookmaster Plus
is a cooker which has the addition of a boiler to supply domestic hot water.

The Rayburn Heatranger
is truly the universal answer to all your household requirments; it cooks wonderfully, provides piping hot water and can run your entire central heating system - all at the same time!

Cookmaster Message
	From high-heat cooking which quickly brings out the best in vegetables to gentle roasting and brilliant baking; the Cookmaster is master of all culinary styles. The Cookmaster's strength is its versatility. The Rayburn Cookmaster is an authentic range cooker benefiting from indirect heat technology. We call this 'kind-to-food' heat because rather than allowing food to dry out it seals in the flavours and natural juices, creating healthier, more delicious dishes. Truly an object of desire - manufactured from cast iron and enamelled in an attractive choice of colours, a Cookmaster will transform your kitchen into a warm and welcoming space.
Heatranger Message
	The Rayburn Heatranger is supremely versatile and efficient. The Heatranger delivers superb range cooking performance along with hot water and/or central heating. Thermostatically controlled to automatically maintain a constant temperature. The Heatranger saves space by combining cooking and heating in one compact unit. Truly an object of desire - manufactured from cast iron and enamelled in an attractive choice of colours, a Heatranger will transform your kitchen into a warm and welcoming space.
The Thermodial
	Common to both the Cookmaster and the Heatranger, the Thermodial gives a guide to the internal oven temperature. The Simmer section temperature range is between 90 & 150°C, the Bake section 150 & 200°C and the roast section 200 & 250°C.

Frequently Asked Questions
Will the chimney need lining?		Generally, yes, but it depends on the flue construction. A professional survey will determine this.
How much approximately does it cost to install a Rayburn Heatranger?		This will depend entirely on site requirements. A profession site survey will be required with any Heatranger installation.
How much does a Rayburn cost per year to run compared to a normal cooker?		Fuel costs are similar. Refer to published fuel consumption comparison chart. Again, there are many variables, such as lifestyle, usage, model and system design. Bear in mind that the presence of a Rayburn in the kitchen will possibly eliminate the need for a radiator there, and its space warming feature is an important plus point.
What warranty comes with a new Rayburn and what does it cover?		3 years and 12 months labour. Certain components are chargeable consumable items and will need to be replaced at service intervals. Refer to guarantee documentation. Optional extended warranty covering labour costs is available.
Does the boiler have an extra warranty on Heatranger models?		Yes. 5 years parts warranty.
Will we need another cooker for the summer?		With the 400 series, probably not, as it can turned on during cooking periods only.
Will my children be safe when a Rayburn is in operation?		A Rayburn is generally safer than most conventional cookers as there are no naked flames or very hot electric elements to touch. It's controls are also hidden away. Although the 'body' of a Rayburn is hot to the touch, its surface temperatures are not likely to cause significant injury and children soon learn to avoid hot objects. However, as a general safety matter, children should not be allowed to play with a cooker or its controls or to interfere with fires or burners.
What happens in a power cut when a Rayburn is in use?		Solid fuel models, as well as the 208G, 200K, 208K, 300K and 309K will continue to provide cooking and DHW. The 368K has a manual override lever to also provide cooking and DHW during power cuts. All Rayburns will go into safe mode when the electricity supply is interupted and should automatically restart when it is restored. None of the 400 Series, nor the 200G, will operate during a power cut.
What is the noise level from a pressure jet burner in a Rayburn?		Compares favourably with any other pressure jet applianceand is probably quieter than previous generations of range cooker. Actual sound level readings (i.e. decibels) are pretty meaningless, due to other site factors such as property location and environment. Conventional flue models will generally be quieter than balanced flue, particularly if appropriate flue pipe materials are used. Balanced flue models are quieter in the actual kitchen but may create more noise at the vent outside. Noise acceptability is very subjective and therefore it is recommended that potential customers are invited to hear the product running and then make their own judgement.
Do you make a gas balanced flue Rayburn?		Not at present, but there is a power flue option for the 400G.
Do I have to leave my Rayburn on all the time?		Traditional models are designed for continuous operation and are adjusted to provide the required temperatures. Rapid Response models are designed to be able to be turned on and off as required and heat up fast. If required they can also be operated on a special low setting to give a gentle warmth to the kitchen.
Will a Rayburn keep my kitchen aired and cosy?		Yes. A Rayburn gives off warmth into the kitchen. As there are two basic groups of Rayburn - traditional, continuously burning models and the new generation Rapid Response models - obviously the latter will only provide warmth during the period when they are programmed to be on.
Is it better to have a cooker only Rayburn and a separate central heating system?		In some instances this might be the preferred option, especially if you want a different fuel for cooking and heating. It will depend on the design of the property and installation. Lifestyle also plays a part. The Heatranger 400 Series is designed so that the cooker and central heating burners are controlled separately.
Can I cook without running the central heating?		Yes. All twin burner models have separate burners for the ovens and the boiler.
Can you control the water temperature separately to the ovens>		Yes, with the 400 Series. Separate burners are used for the ovens and boiler repectively.
Do you make a left hand flue model because our chimney is on the left?		No. Right hand only. Where a chimney is not located conveniently, a balanced flue or power flue model might be more appropriate.
Can you time the ovens to come on and off?		Yes, with the 400 series. 440, 460, 480 & 499K have an integral programmer. 400 models have an integral one-event timer, but can be fitted with an optional external programmer. 480G/AL (CF) models may be fitted with an external programmer. Even the 200G could be fitted with an external timer.
How many radiators can a Heatranger run?		It depends on radiator size/shape/output and heating requirements of the property, but typically: 440 = 8, 460 = 12, 480 = 16, 499 = 20. To some extent it will also vary according to domestic hot water demands.
Would you recommend we have a radiator in the kitchen with a Rayburn?		A Rapid Response model may be turned off for a long periods and therefore alternative heating might be required in the kitchen. With other models it depends on the size of the kitchen, but it probably won't be necessary. If a radiator is installed, it should be fitted with a thermostatic valve, to compensate for the possible varying heat outputs of the Rayburn due to the various cooking operations carried out.
Do you get domestic hot water for free with a Heatranger?		No. There will always be an increase in fuel consumption to generate hot water. A Rayburn can be a means of providing economic domestic hot water, dependant on the type of system fitted, particulaly with the continuously burning traditional models - 212S, 208K, 308K, 208G.
Does the Rayburn require clearance at the side?		It depends on the model. In general, 200 & 300 series do, but 400 series don't. Please refer to Rayburn Technical at www.aga-rayburn.co.uk
How about the pipe work?		The cooker is intended to go flush with the wall, unless the wall is of combustible material, when there should be a gap of 25mm. Water and fuel pipes come out of the side of a Rayburn and should avoid travelling around the back of the cooker.
Does the Rayburn have to be positioned against a wall?		No. With the introduction of a power flue, gas fired and oil fired Rayburns can now be installed in locations previously considered impossible, in virtually any position in the kitchen, including island and peninsular settings.

Glossary

Rayburn Codes

Flue Types
Conventional Also known as Open Flue: The Rayburn needs to be installed using either a lined masonary chimney or a pre-fabricated twin-wall system.		Balanced Flue The Rayburn must be positioned against an outside wall for this option. No chimney is needed; the flue pipe goes directly through the outside wall. Wall thickness: Standard: 250mm to 430mm Optional Extension: 430mm to 880mm		Power Flue Rayburns with power flues can be positioned virtually anywhere in the home, up to a maximum of 5 metres and 5 bends from the outside. A 50mm pipe travels from the Rayburn to a fan on the outside wall.

Burner Types
Gas Atmospheric Gas Used in both continuously burning and Rapid Response models. (Different outputs) Silent operation. Simple construction.	Oil Vaporising Oil Used in the continuously burning models. Near silent. Non-reliant on electricity.
Premix Gas Used in the Rapid Response 400 Series models. Near silent. Automatic.	Pressure Jet Rapid Response burner. High output.

Controls

There are 5 different types of controls for Rayburn.
Manual - The Rayburn is adjusted manually
Integral Oven Timer (IOT) - A one-event timer. The timer is preset and the Rayburn will respond to the on/off times.
Thermostatic (TH) - When the Rayburn reaches a set temperature it turns off - a constant temperature is maintained.
Integral Programmer (IP) - The Rayburn can be programmed to turn on/off up to 3 times a day on a 7 day schedule.
Optional Wall Programmer (OWP) - The Rayburn can be programmed to turn on/off up to 3 times a day on a 7 day schedule.

Base/Hearth/Plinth

A base(hearth) of non combustible material is required for a Rayburn.
The minimum thickness for each fuel is:

The correct base for a Rayburn to stand on is important:

It must br of a non combustible material e.g. stone or concrete

Building regulations demand that it should be non combustible for a minimum thichness of at least the dimensions shown above.

It must also be strong enough to carry the weight of the Rayburn.

Specialist advise may be required if the Rayburn is not to be installed on a solid ground floor. e.g if there are cellars underneath or the floor is suspended.

It must be absolutely level in all directions.

Plinths are only required if you want to alter the height of your Rayburn.

400 Series are of standard worktop height (910mm) and do not require a plinth.

200 & 300 Series have a working height of 820mm and therefore require a plinth of 90mm if you wish to raise the cooker to standard work top height. The plinth must also be made of non combustible material and be of the same width and depth as the base of the Rayburn.

A Guide to Fuel Consumption

Rayburns are all about choice and flexibility. Some models are designed to burn continuously and are adjustable between idling and higher burning rates, whilst others are intended to be used as on/off cookers; fully programmable for intermittent use.

It is therefore, difficult to generalise on or predict fuel consumption, taking into account the variable factors such as amount of usage and size of heating system etc, which will vary considerably from household to household.

The following figues are chosen as typical examples of average fuel consumption and may be of assistance. Figures quoted are approximate over a 24 hour period.

Example 1 - Cookmaster 400 Series
Use:	Full burning rate for cooking - 2 hours Off - 22 hours
Fuel:	Model 400K 2.8 litres / 0.6 gallon kerosene oil Model 400G 29 kW/hr Natural Gas Model 400L 4.1 litres Propane gas

Example 3: Heatranger - Cooking/DHW/CH (continuously burning)
Use:	Full burning rate for cooking - 2 hours + full central heating for 6 hours + 455 litres of domestic hot water.
Fuel:	Model 355M 30kg / 66lb Sunbrite smokeless solid fuel Model 368K 22 litres / 4.0 gallons Kerosene oil Models 480AG(CF) 206 kW/hr Natural gas Model 480AL(CF) 26 litres / 13 kg Propane gas

Example 2: Heatranger - Cooking/DHW (continuously burning models)
Use:	22 hours idling + 2 hours at full burning rate. Cooking + 455 litres (100 gallons) of domestic hot water + background warmth to the kitchen.
Fuel:	Model 212S 10Kg / 22 lb Sunbrite smokeless solid fuel Model 208 or 308K 7.75 litres / 1.7 gallons Kerosene oil Model 208G 88 kW/hr Natural gas Model 208L 12.2 litres / 6 kg Propane gas

Heatranger - Cooking/DHW/CH (intermittent)
Use:	Full burning rate for cooking - 2 hours + Central heating for 6 hours + 455 litres domestic
Fuel:	Model 480K 20 litres / 4.5 gallons Kerosene oil Models 480AG(CF) 192 kW/hr Natural gas Model 480AL(CF) 24 litres / 12 kg Propane gas
