I have recently moved properties, my old property had a coal heating system and the domestic water was constantly hot. The new property is gas central heating and fitted with a Worcester Greenstar 30Si Combi Boiler, the problem that I have is that it takes ages for the domestic water to get hot something like two minutes, even then it is just gets hot, when the hot tap is turned off and on again with a 1 minute break the water is extremely hot.

I am going onto a water meter soon, so I am worried about all of this water loss while waiting for the water to warm.

Is this normal for these boilers to take ages for the hot water to come through? or is there possibly a fault?
 
Check the pre heat is enabled? Is the Eco button illuminated?
Eco button illuminated = pre heat off.
Eco button not illuminated = pre heat on
Hold eco button down for 3 seconds to turn on/off
The pre heat keeps the boiler hot water plate heat exchanger hot to reduce cold draw off time. It does mean the boiler firing up briefly now and then to maintain tempreature.
May be worth checking as a start..
 
There's not a lot else you (as the user) can physically do apart from turning the temperature up and try reducing flow rate when initially turning the tap on..
A combi boiler will always need a bit of time to ramp up and get to a stable temp. 2 minutes over a 3m or so pipe run does seem long.
If it's still not satisfactory get an engineer round to check the boiler out.
 
Probably just normal combi operation, if your flow rate is low it might take 2 minutes to get draw that water through? The tap might be 3 meters away but the plumbing could be travelling a lot further etc depending on route

I agree exactly normal combi operation which is why I have never been in favor of them. I would go with a traditional system every time but everything nowadays needs to be cheap and fast which is why there is millions of rubbish heating systems out there with combis installed which people think are good because the radiators get hot quicker than their previous baxi bermuda (comparison). Quick rant sorry
 
if theres nothing wrong with the boiler (once the gas eng has been out) have a look at combi save
