The coil has a significantly larger heat dissipation surface compared to a heater of the same capacity where one coil is designed for use with a boiler. The larger surface of the coil makes it possible to maintain the required heating capacity for heating domestic water at a lower flow temperature - in the range of 50-60°C. Favorable operating conditions are also guaranteed for low-temperature heat sources - a heat pump or a condensing boiler.\u003c\/p\u003e\u003cp\u003eAn additional optional heat source can be an electric heater - the heater allows installation in a separate 6\/4\" stub. An additional inspection opening with a diameter of 150 mm, built into the lower part of the heater, facilitates maintenance and allows for the installation of any additional accessories.\u003c\/p\u003e\u003cp\u003eThe buffer is characterized by low heat losses thanks to the use of thermal insulation made of rigid polyurethane foam with a thickness of 50 mm. The energy efficiency class \"C\" proves a very high standard in its class and size of heaters, while maintaining an optimal balance between energy efficiency and purchase and operating costs.\u003c\/p\u003e\u003cp\u003eThe outer casing is made of hard plastic with increased resistance to dirt and mechanical damage. The internal steel surfaces are coated with ceramic enamel to protect against corrosion. Additional protection is provided by the magnesium anode, which is supplied as standard with the heater. The buffer can be placed directly on the floor and leveled precisely thanks to the adjustable feet.\u003c\/p\u003e\u003cp\u003eOVERVIEW OF FEATURES:\u003cbr\u003e1 heating coil with a significantly larger heat dissipation surface\u003cbr\u003eDesign adapted to work with a reduced flow temperature (heat pump, condensing boiler)\u003cbr\u003eThe recommended ratio of exchanger surface to heat pump heating power is 0.2 m2 \/ kW (inverter compressor) or 0.3 m2 \/ kW (ON\/OFF compressor)\u003cbr\u003eEffective protection against corrosion thanks to the use of the Crystal Enamel® enamel surface\u003cbr\u003eOptimal balance between energy efficiency and purchase price and operating costs\u003cbr\u003eProtective magnesium anode for additional protection of the internal surfaces of the heater\u003cbr\u003eMinimization of heat losses through the use of ThermoGen® rigid polyurethane foam\u003cbr\u003eHard plastic casing, easy to keep clean\u003cbr\u003eThermometer on the heater casing for reading water temperature and operating the heater\u003cbr\u003e6\/4\" stub pipe for mounting an electric heater, e.g., for emergency domestic hot water heating\u003cbr\u003e170 mm inspection opening in the lower part of the heater for maintenance or installation of additional elements\u003cbr\u003eAdjustable feet for leveling the heater on the room floor\u003cbr\u003eFavorable 5-year warranty conditions\u003cbr\u003eTECHNICAL DATA:\u003c\/p\u003e\u003cp\u003eDiameter: 584 mm\u003cbr\u003eHeight: 1541 mm\u003cbr\u003eWeight: 119 kg\u003cbr\u003eExchanger surface: 2.5 m2\u003cbr\u003eAllowed working pressure: 10 bar\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIf the products are not in stock, prices may change.\u003cbr\u003eWe will inform you in good time.\u003cp\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"JustFire Group","offers":[{"title":"Standaard","offer_id":56408954372470,"sku":"HW-81.10.09-OKC250NTR \/ HP","price":1595.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/6631\/1542\/files\/water-heater-234-l-drazice-okc-250-ntr-hp.jpg?v=1762873699","url":"https:\/\/justfire.nl\/en\/products\/zonneboiler-300-liter-met-2-warmtewisselaars-hoog-model-2","provider":"JustFire Group","version":"1.0","type":"link"}
