We believe that the upcoming BESA HIU tests with lower temperatures will clearly demonstrate that the vTherm HIU range is the right choice for 4<sup>th<\/sup> generation district heating and renewable energy sourced projects.\u201d<\/p>\n<p>The vTherm range of HIU\u2019s also recorded the lowest VWART (Volume Weighted Average Return Temperature) results when independently tested against the BESA criteria at 60 degrees.\u00a0 This, alongside its low heat losses, showed our HIU\u2019s to be the most efficient on the UK market.<\/p>\n<p>We are currently installing our vTherm units on the Queens Quay Project in Scotland, which is the first large-scale water source heat pump project in the UK.<\/p>\n<\/p>\n<\/div>\n<\/div>\n<div class=\"quote\">\n<div class=\"wrap quote__wrap\">\n<div class=\"swiper-container js-simple-quotes\">\n<div class=\"swiper-wrapper\">\n<div class=\"swiper-slide\">\n<div class=\"quote__holder\"><span class=\"quote__icon\"> <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"36\" height=\"28\" viewbox=\"0 0 36 28\"><g fill=\"#F58220\" fill-rule=\"evenodd\"><path d=\"M12.319 0h3.648a2 2 0 0 1 1.838 2.788l-10.286 24A2 2 0 0 1 5.681 28H2.033a2 2 0 0 1-1.838-2.788l10.286-24A2 2 0 0 1 12.319 0zM30.319 0h3.648a2 2 0 0 1 1.838 2.788l-10.286 24A2 2 0 0 1 23.681 28h-3.648a2 2 0 0 1-1.838-2.788l10.286-24A2 2 0 0 1 30.319 0z\"><\/path><\/g><\/svg> <\/span><\/p>\n<div class=\"quote__holder\">\n<p class=\"quote__text\">\u201cAfter years of Whitecode and Vital working on challenging and interesting projects together it was only natural that Vital would turn to Whitecode to help them understand the value of their new HIU and the systems Whitecode regularly design.
