Underfloor heating usually costs more upfront because it involves floor build-up, insulation, pipework or electric matting, controls and sometimes screed.\r\n      <\/div>\r\n    <\/div>\r\n\r\n    <div class=\"kws-faq-item\">\r\n      <div class=\"kws-faq-q\">Which is cheaper to run?<\/div>\r\n      <div class=\"kws-faq-a\">\r\n        Wet underfloor heating can be efficient when designed properly because it can run at lower flow temperatures. Electric underfloor heating can be expensive to run in large areas. Radiator running costs depend on boiler efficiency, radiator sizing, controls and insulation.\r\n      <\/div>\r\n    <\/div>\r\n\r\n    <div class=\"kws-faq-item\">\r\n      <div class=\"kws-faq-q\">Should I use underfloor heating in a kitchen extension?<\/div>\r\n      <div class=\"kws-faq-a\">\r\n        Yes, it is often a good choice for kitchen extensions because it frees up wall space, works well under tiles and gives even warmth in open-plan rooms.\r\n      <\/div>\r\n    <\/div>\r\n\r\n    <div class=\"kws-faq-item\">\r\n      <div class=\"kws-faq-q\">Can underfloor heating replace radiators completely?<\/div>\r\n      <div class=\"kws-faq-a\">\r\n        Yes, in some rooms it can replace radiators if the system is correctly designed for the heat demand.
