Introducing The New Heatranger

Rayburn Heatranger 60K, 80K & 100K
Oil with Chrome Lids trim.

The Rayburn Heatranger is reliable, flexible and controllable, offering hot water, heating and radiant heat cooking. With large capacity cast-iron ovens for roasting, baking and simmering, and a large hotplate for boiling and simmering, the Rayburn Heatranger allows you to master all culinary styles.

The Heatranger has HVO (95% Hydrotreated Vegetable Oil) compatible burners making the appliance eco-friendly, carbon-free and future-ready. HVO is invaluable in helping the UK achieve its net zero carbon target, reducing up to 90% of net CO2 emissions.

Thanks to its digital display and electronic controls, you can easily control cooking and boiler functions independently. The Rayburn Heatranger 60K offers a boiler output of 60,000 Btu/h or 17.58kW, 80K offers a boiler output of 80,000 Btu/h or 23.45kW and 100K offers a boiler output of 100,000 Btu/h or 29.3kW.
