Why do I have poor hot water pressure?

If your cold water pressure is fine, but your hot water pressure if poor, there could be a number of reasons why.

Some of the reasons flagged in our section of water pressure problems could affect your hot water independently. For example, having a valve on your hot water pipes that is not fully open, long pipe runs or multiple sharp bends.

A more likely cause of low pressure of how water would be the source of the hot water itself.

If you have a combi boiler, your hot water flow is restricted at the boiler.

Cold water on the other hand has pressure from the height of the water tank, as is the case with gravity fed hot water, or it comes from the mains at around 1 bar. Both of these are likely to have higher water pressure than water from a combi boiler.

If you are suffering from hot water pressure problems you should consider a Proflo water pressure booster.
