{"product_id":"colenzo-black-vertical-2-column-radiator","title":"Colenzo Black Vertical 2 Column Radiator","description":"\u003cp\u003eColenzo is a steel multi-column radiator with the classic look of a traditional column radiator and the speed and lightness of steel. A black finish turns the radiator into a design feature, striking against white, grey or boldly painted walls.\u003c\/p\u003e\u003cp\u003eChoose from 3 sizes with outputs from 3,885 to 6,105 BTU\/hr at ΔT60, so you can match the radiator to the room. It is made from steel, pressure tested to 10 bar, and its large surface area makes it a good choice for bigger rooms. Radiator valves are sold separately.\u003c\/p\u003e\u003ch3\u003eSpecification\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eFinish\u003c\/td\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eSteel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrientation\u003c\/td\u003e\n\u003ctd\u003eVertical\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColumns\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth\u003c\/td\u003e\n\u003ctd\u003e70mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnections\u003c\/td\u003e\n\u003ctd\u003e1\/2\" BSP tappings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure\u003c\/td\u003e\n\u003ctd\u003eTested to 10 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eValves\u003c\/td\u003e\n\u003ctd\u003eSold separately\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGuarantee\u003c\/td\u003e\n\u003ctd\u003e5 year manufacturer guarantee\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eSizes and heat outputs\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSize (H x W)\u003c\/th\u003e\n\u003cth\u003eOutput BTU\/hr (ΔT60)\u003c\/th\u003e\n\u003cth\u003eOutput watts (ΔT60)\u003c\/th\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1800x335mm\u003c\/td\u003e\n\u003ctd\u003e3,885\u003c\/td\u003e\n\u003ctd\u003e1,139\u003c\/td\u003e\n\u003ctd\u003e21.4kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1800x425mm\u003c\/td\u003e\n\u003ctd\u003e4,995\u003c\/td\u003e\n\u003ctd\u003e1,464\u003c\/td\u003e\n\u003ctd\u003e27.05kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1800x515mm\u003c\/td\u003e\n\u003ctd\u003e6,105\u003c\/td\u003e\n\u003ctd\u003e1,789\u003c\/td\u003e\n\u003ctd\u003e32.7kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003cp\u003e\u003cem\u003eOutputs are quoted at ΔT60, the manufacturer's test standard.
