CotswoldDoItUpper Posted January 19, 2022 Share Posted January 19, 2022 Is it possible to work out the output of a radiator at a certain delta? I’m not sure our plumber has sized our new rads correctly despite insisting that they’re ok. They’re column rads, and we’re looking for a delta of 50 not 65 which is what I think he is using. Thanks!

JohnMo Posted January 19, 2022 Share Posted January 19, 2022 Have a look on the manufacturer website, they now list various delta T, if not give them a call or the UK agent. Link to comment Share on other sites More sharing options...

Roundtuit Posted January 19, 2022 Share Posted January 19, 2022 These maybe? https://www.radiatoroutlet.co.uk/600-x-608mm-white-horizontal-traditional-2-column-radiator Link to comment Share on other sites More sharing options...
JohnMo Posted January 19, 2022 Share Posted January 19, 2022 Did a simple Google search for the number of columns and overall size found this, different colour, but same size and number columns, which gives a T50 rating. Will be pretty similar if not the same rating https://www.homesupply.co.uk/Eastbrook-Rivassa-600-x-608-Matt-Anthracite-2-Column-Horizontal-Radiator Link to comment Share on other sites More sharing options...
CotswoldDoItUpper Posted January 19, 2022 Author Share Posted January 19, 2022 Thanks @Roundtuit and @JohnMo. thus is for a room that needs around 4900BTU. The plumber has specified 2 of them knowing we’ll be running out heating at 50deg and knowing we want to upgrade to a heat pump in the future. radiator outlet says 2700BTU per rad but with no delta, home supply suggests 2200BTU at a delta of 50. should I get the plumber to change them for something bigger?

JohnMo Posted January 19, 2022 Share Posted January 19, 2022 The 3 column one is 2853 BTU. https://www.homesupply.co.uk/Eastbrook-Rivassa-600-x-608-Gloss-White-3-Column-Horizontal-Radiator?gclid=Cj0KCQiAip-PBhDVARIsAPP2xc182-ebOJ-_LCV6gYPnx90wMzdnD3iF7siji72roHjODDIc6FgneJ8aAjcBEALw_wcB That would be better suited. If you are going ASHP, the bigger the better really, even go the next size up if you have room Link to comment Share on other sites More sharing options...
