potted history of rayburn solid fuel cookers post - Harworth Heating Ltd

THE SUPREMEwhich also altered the oven temperature byallowing more or less air to the fire grate.Available in a limited range of colours, it had abrown top-plate and enamelled lids and wasalso available in a Matt-finish black or brownenamel, the latter with brass colour fittings.Manufacture had ceased by 1992, beingreplaced by the Nouvelle, which had beenintroduced in the mid 1980's.RAYBURN SOLID FUEL NOUVELLERayburn 300W, 345W, 355S, 355M &355SFWThe Rayburn Supreme was introducedin 1982 for use with a range of solid fuels andalso wood and peat. It provided cookingtogether with domestic hot water and heating.It was only produced with ovens on the righthand side.The fabricated steel boiler was originallyquoted as providing 35000BTU/Hr (10.3KW),based on a 4 hour re-fuelling cycle, inaccordance with B.S. 1252. This was achievedby maintaining a high oven temperature andselecting the 'heating' position on the controldamper. The output figure reduced to20000BTU/Hr (5.8KW) when burning wood.During summer use when the firebrickpositions were changed, the output reduced to3.1KW (for solid fuel use) with the 'cooking'position of the control damper selected. Theboiler temperature was controlled using thethermostat sited at the rear of top plate.The appliance was fitted to a heating systemwith the circulating pump on the return pipebefore the junction of the return from theindirect cylinder. The domestic hot water isavailable constantly, while the appliance isalight, by using an open vented gravity feed190 Litre (40 gallon) cylinder. The pump canbe controlled by a programmer and/or roomthermostat, and it was recommended that aboiler low temperature return thermostat befitted.The hotplate had 2 hinged insulating lids, theheat being provided by the hot flue gasespassing across the underside. The temperaturebeing regulated by use of the spin wheel,The Rayburn Solid fuel Nouvelle wasintroduced in the mid 1980's, to initiate a newrange of central-heating cookers intended foruse with a range of solid fuels and also woodand peat. Oil & Gas Nouvelle's weresubsequently introduced.Similar to the Rayburn Supreme, the Nouvelleoffered wider choice of colour options andchrome insulating covers.It provided cooking together with domestic hotwater and heating. It was only produced withovens on the right hand side.Advantage was taken to quote the boileroutput ratings in accordance with the newEuropean Standards, which permitted a 2 hourre-fuelling cycle. Therefore, although thefabricated steel boiler was identical to theRayburn Supreme model, it was quoted ashaving the higher maximum output of16.1kw/hr (coal) 5.9kW/hr for wood. This was4
