Boiler works fine most of the time, but occassionally there is a dela in the hot water. Sometimes when the bathroom basin tap is run there i piping hot water coming out which is great, but turn the tap off an turn on a bath tap or the shower full blast afterwards, and the wate runs from hot to luke warm to nearly cold, before eventually comin back to being piping hot again! This can take a minute or longer.
The pipe run from the boiler to the bathroom is less than 5m across th landing, so it can be a case of the water in the pipe getting cold as i does not have time, and it would take less than a couple of seconds t run the water out of that length of pipe anyway. It seems to be th boiler getting confused with switching on, then off, then immediatel on again.
I know this model is supposed to keep small back up of hot water, but sense this may be causing the problem.
This drives me mad when it happens. Like I say, it does not happen al of the time, and was considering tapping up my local agent to check i out.
Should I be concerned (I am because it cost me a small fortune t install and expect it to work right) and should it do this in the firs place?
Hopefully, there is someone out there who knows the exact in's an out's of combi's and why they do this!!
