Hi, Just to provide an update and close this off. I've just had the ecoTec 831 fitted. Got the Honeywell CMT927 fitted at the same time. So far very pleased, though we've only used the DHW in anger.
Thanks to all for your contributions. Now I can get back to sorting out my Burglar Alarm.
When I am asked to replace a part based on some one else's diagnosis I require to be paid with cash BEFORE I start.
A lady in Shepherds Bush who worked for the BBC actually apologised when I replaced the pump instead of the asked for PCB and it was a cheaper repair for her!
I always ask why the person who diagnosed the fault does not want to do the repair! Amazingly it often turns out they are actually builders!
Where do you get rapid hot water flow from ? You've never been to the house , the flow from my 837 is better than from my vented cylinder in my old house I can run a bath , granted not at 60c (not needed anyway),at a temp suitable that a human can actually get in and quicker than I could wi my vented cyl and that was a 22mm feed , also has he not said he showers mainly which is electric ? A combi will suit fine from what I've read , as for price I can't / won't comment as again nobody knows what's been quoted for , so can't accurately comment , I personally would have Unvented hot water and a heat only however it's not nessacary it's what I prefer
