The classic simple styling of the Tortoise Built-In Firebox, available in the widest selection of sizes, is perfectly suited to so many situations – they’ve been gently house-warming for more than 25 years. If a standard size doesn’t quite fit the bill, we offer a unique made-to-measure service which can be a cost-effective and less intrusive option than having to alter an existing opening. Happy to burn the fuel of your choice – wood, coal or gas, straightforward to install, with most existing chimneys being suitable, the Tortoise open convector fire has to be a front runner.
