Ever since it was fitted 2 years ago, my Ideal Exclusive 35 has taken an absolute age to provide hot water. I timed it today and, it was 55 seconds to get hot water at the closest tap to the boiler and around 1m5s at the furthest tap. I know combis can take a few seconds to provide hot water but, when you want some warm water to quickly wash your hands after going to the loo, waiting a minute is an absolute age and I give up. Observations: - pre-heat seems to do absolutely nothing - the boiler can even be hot from providing hot water and if I even wait 2 minutes before turning on a tap again, the last of the warm water comes out and I'm back to cold water waiting another minute for it to get hot again - It doesn't matter what the flow rate - it could be a slow trickle from a tap or the rainfall shower, the wait for hot water is the same - water pressure is 2.8 bar - gas pressure is 20-21 - closest tap is approximately 7 metres of pipe from the boiler, most of which has lagging - if using the heating, all radiators feel warm already in less than about 90 seconds, which I think is pretty impressive - waiting so long for hot water means I'm running up the water bill, wasting 6-8L of cold water every time I run the tap Can anyone help suggest what the issue is or if it's normal for these boilers? From my perspective, it is not normal. My Dad has a similar set up in his house and his Potterton gives hot water in around 10-15s. I don't know anything about boilers but, as I've had the issue from new, I feel like it could be something like a temperature sensor/thermocouple not activating or maybe some kind of sticky valve?
