hi all, was wondering if someone could help me out with some electrical knowledge.
bought a new heating element, 240v 2500w it said on the package.(i live in the uk where mains is 230v). installed it to my 50ltr boiler and yep it took extremely long time to bring water to mash temp - almost 2.30 hours. according to some online calculator to achieve a 70c temp rise in 50 ltr of water with a 2500w element should take about 100 minutes and not 140 minutes it took me. so i grabbed my multimeter and measured the resistance of the heating element which was 30 ohms. according to this calculation R = (V x V) / P (V is the voltage P is watts) resistance should have been around 23ohms. which tells me that the heating element is around 1900w and not 2500w. am i right to assume that? wanna make sure Im correct before i contact the seller.
cheers
