is a mira 88 mixer shower suitable for use with a combi boiler?mixer was originally tank fed but obviously wont be if we change to a combi,just wondered if we needed to change mixer.thanks in advance
thanks for quick reply,have neighbour who has same shower as me and since he changed to a combi the cold supply doesnt shut off properly and keeps running from shower head he has replaced seal but still has same problem is this because shower is not designed for combi or does seal just need replacing again.
thanks very much for your help, you have saved me a lot of messing around,i was going to pull it to bits and look at it for him,i'll just fit new mixer for him now instead
I know a few Mira 88's running fine for a few years now on combi's. Mira officially say they are not for use for Combi boilers but are acceptable for mains pressure (ie unvented DHW). Personally I can't see why they should work fine on Unvented but not running off a combi seeing that modern combis are fully modulating and deliver DHW at a constant set temp.
Perhaps someone has reason they are not suitable for Combi's or is it a Mira ploy to sell a new shower when a customer upgrades to a Combi?
