Hot water tap takes a long time to produce hot water

[happyflea]

When I turn on hot water tap in kitchen, the water comes out cold for ages before gradually becoming warm then hot. It's more noticeable in kitchen then anywhere else.

I know this is to be expected to some extent because heat must leave water when sitting in pipe. But the problem seems to be getting worse over months, I have to wait longer for water to become hot.

Any ideas as to cause? If there was a leak somewhere could that cause it?

More detial required.

Are we talking combi boiler or system with hw tank?

 

[happyflea]

hw tank

does the hot water get hot enough in the end?

could have apartial blockage, reducing flow rate and so it takes longer to get there

eh hes talking about a system boiler here mate. theres no way anyone can solve this problem again you need an engineer to attend to diagnose the problem on site

it could be the 3 port blocked or stuck in central heating but passing slightly for hw
it could be the pump
it could be the boiler not staying on long enough
blockages
it could be the cylinder stat

take a pic

sorry techeng, dont understand your argument--could be a partial blockage in either supply to cylinder or in draw off..

Zimmers, I appreciate that English is not one of your strong points but he has said that the hot water is from a cylinder and it takes a long time for the flow to get to the tap from the hot cylinder.

Thats different from the hot water cylinder taking a long time to heat up.

The problem is likely to have a cause like a long supply pipe, perhaps in steel which takes ages to heat up.

and it will have been getting worse over the last four months because the weather, and hence the pipes, are colder.

i'm wondering whether a faulty thermostatic mixer valve could be the problem (if there is one on the system anywhere)

I appreciate that you appear to get emotional when someone questions your comments then again we cant all be perfect can we

Your reply just comes across as if you was referring to a combi system is all it twgas
