Why is the hot water flow from my tap slower than the cold water flow?

Question

Why is the hot water flow from my tap slower than the cold water flow? Any ideas why this might be happening? Can it be fixed DIY usually?

Darren · Answer

It is probably  because it is coming from the hot water cylinder upstairs as you have a sealed system .so it works on gravity .
If you had a combination boiler ,it all works of the cold mains and so the pressure  would come out equally.

It's likely you have mains cold water supplying all of the cold water outlets in your home whilst all the hot water outlets are supplied from an unpressurised gravity fed hot water cylinder. If this is not the case and your cold water (apart from the cold supply in your kitchen) is also gravity fed, then it might be that there is an excessive amount of chalk debris at the bottom of your hot water tank restricting the flow of hot water.

If you’ve got a low pressure system (tanks in the loft) then your hot will be fed from a tank, only being gravity fed. And your cold may be on the mains

Hi 
Because the hot water is passed through boiler or any other heating supply so the problem is with heating supply and also with even new boiler the hot water is not same pressure as cold water

Matthew Martin · Answer

Maybe be its fed from a tank in the loft and the mains will be always more powerful unless you install a pump and reduce mains pressure using a pressure reducing valve
