English Electric engines are notoriously difficult to start in cold weather, and whilst the effect is spectacular, it causes substantial engine wear and problems down the line. Put simply, every cold start takes hours of the life of the power unit. Given steam heat capability will increase the likelihood of the loco being started in cold conditions, pre-heating the engine was therefore considered essential for\u00a0the well being of the power unit.<\/p>\n<p>The pictures below, show the 9kW three phase electric preheater successfully fitted in the loco and plumbed in to the coolant circuit, meaning the loco can now be &#8216;plugged in&#8217; to a 415v shore supply several hours before start up and brought up to temperature ensuring nice clean start up.<!--more--><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-1163\" src=\"http:\/\/thegrowlergroup.org.uk\/wp-content\/uploads\/2016\/11\/15156932_10154132561026347_822098475555349092_o.jpg\" alt=\"15156932_10154132561026347_822098475555349092_o\" width=\"2048\" height=\"1536\" srcset=\"http:\/\/thegrowlergroup.org.uk\/wp-content\/uploads\/2016\/11\/15156932_10154132561026347_822098475555349092_o.jpg 2048w, http:\/\/thegrowlergroup.org.uk\/wp-content\/uploads\/2016\/11\/15156932_10154132561026347_822098475555349092_o-300x225.jpg 300w, http:\/\/thegrowlergroup.org.uk\/wp-content\/uploads\/2016\/11\/15156932_10154132561026347_822098475555349092_o-768x576.jpg 768w, http:\/\/thegrowlergroup.org.uk\/wp-content\/uploads\/2016\/11\/15156932_10154132561026347_822098475555349092_o-500x375.jpg 500w\" sizes=\"auto, (max-width: 2048px) 100vw, 2048px\" \/> <img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-1164\" src=\"http:\/\/thegrowlergroup.org.uk\/wp-content\/uploads\/2016\/11\/15168808_10154132561046347_6207611681630620443_o.jpg\" alt=\"15168808_10154132561046347_6207611681630620443_o\" width=\"1536\" height=\"2048\" srcset=\"http:\/\/thegrowlergroup.org.uk\/wp-content\/uploads\/2016\/11\/15168808_10154132561046347_6207611681630620443_o.jpg 1536w, http:\/\/thegrowlergroup.org.uk\/wp-content\/uploads\/2016\/11\/15168808_10154132561046347_6207611681630620443_o-225x300.jpg 225w, http:\/\/thegrowlergroup.org.uk\/wp-content\/uploads\/2016\/11\/15168808_10154132561046347_6207611681630620443_o-768x1024.jpg 768w, http:\/\/thegrowlergroup.org.uk\/wp-content\/uploads\/2016\/11\/15168808_10154132561046347_6207611681630620443_o-375x500.jpg 375w\" sizes=\"auto, (max-width: 1536px) 100vw, 1536px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Given that\u00a0D6948 has now been\u00a0fitted with a steam generator (for the first time in its history), the owners\u00a0have taken the decision to fit an on-board pre-heater to allow heating of the engine block and cooling system prior to starting the &hellip; <a href=\"http:\/\/thegrowlergroup.org.uk\/?p=1162\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"ngg_post_thumbnail":0,"footnotes":""},"categories":[10,16],"tags":[],"class_list":["post-1162","post","type-post","status-publish","format-standard","hentry","category-10","category-project_d6948_blog"],"_links":{"self":[{"href":"http:\/\/thegrowlergroup.org.uk\/index.php?rest_route=\/wp\/v2\/posts\/1162","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/thegrowlergroup.org.uk\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/thegrowlergroup.org.uk\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/thegrowlergroup.org.uk\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"http:\/\/thegrowlergroup.org.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1162"}],"version-history":[{"count":3,"href":"http:\/\/thegrowlergroup.org.uk\/index.php?rest_route=\/wp\/v2\/posts\/1162\/revisions"}],"predecessor-version":[{"id":1167,"href":"http:\/\/thegrowlergroup.org.uk\/index.php?rest_route=\/wp\/v2\/posts\/1162\/revisions\/1167"}],"wp:attachment":[{"href":"http:\/\/thegrowlergroup.org.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1162"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/thegrowlergroup.org.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1162"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/thegrowlergroup.org.uk\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1162"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
