Warmheart D is a high-quality, eco-friendly heating solution that ensures your home stays warm and stylish featuring a bolster lid & towel rail.
Primarily a 5kW log burner Warmheart D offers space heating capacity up to 100 square metres. The durable exterior conceals super-efficient clean-burn technology that extracts maximum energy from the combustion process and stores heat for many hours after lighting.
Sizzle, steam, toast, braise, boil and fry – the ESSE Warmheart D is designed complete with hotplate and firebox grill. With the most concentrated heat directly above the firebox, a heavy based kettle, pan or griddle can be heated on the hob. As your flames subside to glowing embers you too can achieve that classic restaurant chargrilled flavour by cooking in the firebox.
