hot water and central heating in properties connected to a district heating system using a central boiler.<br><br>\n\nFor some years, there has been an increasing use of centralized boiler plants in property developments. The advantages of removing gas boilers from properties and making use of high efficiency centralized boiler plants are numerous.<br><br>\n\nHowever heat networks are only as efficient as the HIUs they connect to, which is why we are proud to present the UKs officially most efficient HIUs, as demonstrated in the first round of independent testing by DECC, and now BESA.<\/p>\r\n                                        \r\n                                                                                    <div class=\"achoose mb-40 wow fadeInUp2 bdevs-el-list\" data-wow-delay=\"1.2s\">\r\n                                                <div class=\"achoose__icon elementor-repeater-item-a3f7753\">\r\n                                                                                                            <figure>\r\n                                                            <i aria-hidden=\"true\" class=\" flaticon-technician\"><\/i>                                                        <\/figure>\r\n                                                                                                    <\/div>\r\n                                                <div class=\"achoose__text\">\r\n                                                    <h4 class=\"achoose__text--title\">Moulded EPP Insulation<\/h4>\r\n                                                    <p>One way to reduce the rate of heat loss, is to insulate. The range of Thermal Integration HIUs make use of highly engineered EPP (Expanded Polypropylene) moulded enclosures that encase individual components supporting assemblies and preventing any heat bridging to the environment. Heat losses of under 2W are available, making the drain on energy use less than 1 pence per day.<\/p>\r\n                                                <\/div>\r\n                                            <\/div>\r\n                                                                                    <div class=\"achoose mb-40 wow fadeInUp2 bdevs-el-list\" data-wow-delay=\"1.2s\">\r\n                                                <div class=\"achoose__icon elementor-repeater-item-5a4a463\">\r\n                                                                                                            <figure>\r\n                                                            <i aria-hidden=\"true\" class=\" flaticon-satisfaction\"><\/i>                                                        <\/figure>\r\n                                                                                                    <\/div>\r\n                                                <div class=\"achoose__text\">\r\n                                                    <h4 class=\"achoose__text--title\">Economy Mode<\/h4>\r\n                                                    <p>Another way to reduce losses is to allow the system to go cold when not in use.
