I am considering buying a Mikrofill Ethos 54C.
I was originally thinking of a vented or unvented heat store solution (eg Vaillant UniStor or DPS Pandora), but it seems that the Ethos will give me the same real-life performance. The flow rate from the tap on the top floor of my flat is 22l/min. The Ethos 54C gives a flow rate of 25l/min at a 30 degree uplift. If mains water comes in at 10 degrees, then in effect I have 25l/min of shower-temp water from a combi.
This seems like the ideal solution, as there is no limit to the DHW available (unlike a Megaflo or Heat Bank, which will eventually drain and require a recovery time). The only downside seems to be that there's no back-up hot water if the boiler fails as you can't add immersion heaters.
This also seems like a better solution than the ecoTEC plus 937, because while that claims to deliver a slightly better flow rate, it incorporates two unvented tanks and therefore (a) requires building controls approval, etc and (b) those tanks could also empty, leaving you with a lower flow rate again.
Does anybody have any experience with Ethos boilers, or Mikrofill generally? Are they reliable? Are there any other potential problems I have not considered?
Thanks very much for your replies!
