{"product_id":"woodfire-ex-wood-burning-inset-boiler-stove","title":"Woodfire EX Wood Burning Inset Boiler Stove","description":"\u003cp\u003eThe Woodfire EX is a wood burning inset boiler stove that sends most of its heat to water for radiators, hot water or a thermal store, with a smaller share into the room. All three models share the same 634mm wide body, a 200mm top flue outlet and wood-only fuel. Choose the EX10 (10kW), EX15 (15kW) or EX22 (22kW), from a well insulated or low energy home up to the main heat source in a larger home.\u003c\/p\u003e\n\u003ch2\u003eWhy choose the Woodfire EX\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e10kW to 22kW in total, with 8.5kW to 18.5kW going to water and 1.5kW to 3.1kW to the room.\u003c\/li\u003e\n\u003cli\u003e82% to 84% efficiency depending on model, with Woodfire stating Ecodesign compliance.\u003c\/li\u003e\n\u003cli\u003eSame 634mm wide body across the EX10, EX15 and EX22.\u003c\/li\u003e\n\u003cli\u003e200mm top flue outlet and a 125mm external air supply connection; operating pressure 2.5 bar.\u003c\/li\u003e\n\u003cli\u003eTakes logs up to 400mm long; wood and wood briquettes only.\u003c\/li\u003e\n\u003cli\u003e3 year warranty when fitted with a load unit or load valve and installed by a qualified fitter (1 year otherwise).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWill it suit your space?\u003c\/h2\u003e\u003cp\u003eOnly a small part of the output reaches the room directly, so these stoves suit rooms that would overheat with an ordinary stove. As a rule of thumb, an average room needs roughly 1kW for every 14 cubic metres, so the direct room heat of 1.5kW to 3.1kW suits roughly 21 to 43 cubic metres depending on model. Older, draughty or high-ceilinged rooms need more, and a heat-loss check by your installer gives the right answer. Every model is 1107mm high, 634mm wide and 545mm deep; check the sizes table below for the output and weight of each. Woodfire asks for 400mm clearance to combustibles at the rear and sides and 1000mm in front.\u003c\/p\u003e\n\u003cdiv class=\"gf-sizes\" id=\"gf-sizes\"\u003e\n\u003ch2\u003eSizes and options\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth scope=\"col\"\u003eModel\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eWeight\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eHeat output\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eEX10\u003c\/th\u003e\n\u003ctd\u003e177kg\u003c\/td\u003e\n\u003ctd\u003e9.9kW nominal (8.5kW to water, 1.4kW to room)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eEX15\u003c\/th\u003e\n\u003ctd\u003e179kg\u003c\/td\u003e\n\u003ctd\u003e14.9kW nominal (12.5kW to water, 2.4kW to room)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eEX22\u003c\/th\u003e\n\u003ctd\u003e181kg\u003c\/td\u003e\n\u003ctd\u003e21.8kW nominal (18.5kW to water, 3.3kW to room)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gf-desc-specs\"\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eWoodfire\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFuel\u003c\/th\u003e\n\u003ctd\u003eWood and wood briquettes only\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions (H x W x D)\u003c\/th\u003e\n\u003ctd\u003e1107 x 634 x 545mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFlue\u003c\/th\u003e\n\u003ctd\u003e200mm, top outlet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eExternal air supply\u003c\/th\u003e\n\u003ctd\u003e125mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaximum log length\u003c\/th\u003e\n\u003ctd\u003e400mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOperating pressure\u003c\/th\u003e\n\u003ctd\u003e2.5 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e3 years with a load unit or load valve, installed by a qualified fitter (1 year otherwise)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEfficiency\u003c\/th\u003e\n\u003ctd\u003e84% (EX10); 83% (EX15); 82% (EX22)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch2\u003eInstallation and safety\u003c\/h2\u003e\u003cp\u003eIt must be installed by a HETAS-registered installer or signed off by Building Control, and a carbon monoxide alarm is required in the room.
