I have the same problem in that it takes a long time for the hot water to get hot. However, this is a recent problem as it has all been fine in the past.
Any ideas?

You piggybacked onto a 6 year old thread so I gave you one of your own.
Is this affecting the entire house or just one fixture? Back to you, Tom

The taps in the back of the house (Hot Water Heater is in front of house) have always taken an unusually long time to get hot but the kitchen tap (front of house) just started to take a much longer time to get hot or even warm.
Thank you for pointing out how old that thread was where I first asked this question.
