Firstly hello, i did a quick search and wasn't sure whether this should be in here or the central heating section so if i've got it wrong i apologies! We are looking to replace our current vented system with an unvented indirect 210l cylinder to replace the current pump used for two deluge showers and the bath. Main reason for change is the noise and due to the way it was installed the pump struggles to provide the pressure. Its worth adding we have great cold water mains pressure. So we've been looking at numerous cylinders and the prices vary greatly! I have seen a Sapphire cylinder which i believe are made by Heatrae Sadia but maybe someone could confirm that? this cylinder is cheap in comparison so wondered if anyone has any experience as to whether these are any good? my concern is i dont want to purchase something because its cheaper and it end up not being fit for purpose, but on the same note dont want to spend more if it is not required... Greatful for any advice for alternative options to consider. Thanks in advance.
