No Hot Water Coming Out of Tap?

One of the most annoying issues for any homeowner can be no hot water coming out of the tap. If this happens to you before you grab the phone to call someone, try this quick and practical list of possible causes and fixes.

Check Your Electric, Gas and Water

Make sure your energy supply is not only working as it should but is connected properly, whether your home has an electric or gas boiler. And although it sounds obvious, make sure your water supply hasn’t been inadvertently turned off.

Reset Your Boiler

In some cases, this problem can be easily resolved by switching off the power to the boiler and then switching it on again or reset your boiler by using the customer operated reset switch.

Thermostat

Check that the setting on your thermostat hasn’t accidentally been adjusted to a lower setting. Try turning the setting up high for a few minutes and once you have hot water again, set the temperature to a more normal setting; this quick fix can sometimes do the trick.

Clock and Timer

Check that you have the timer set for the right time for your water to heat up, and also that the clock itself is set to the correct time. It’s all too easy to overlook the clock on the boiler when it’s that time of the year to put the clocks ahead or back.

Power Cut

Your boiler may have been restored to its factory settings and not working as it should if your power went out and then came back on a short time later. Alter any settings as needed if you feel this is what is causing no hot water coming out of the tap.

Diverter Valve

This is a small but essential part of your heating system which opens and sends hot water to your taps, as it allows a combination boiler to alternate between heating the water and the radiators. The valve sometimes gets stuck in the open position, or may just need replacing.

Airlocks in the Pipes

Blockages can be caused by air becoming trapped in the pipes and if your cold water seems okay, attach a hosepipe to the cold water tap and turn it fully on. Often, this will get rid of any airlock if you leave the tap on for a few minutes.

Commercial Plumbing Maintenance

Let the experts check the condition of pipes, faucets, valves and joints to ensure they are in good condition.

Low pressure – Sealed System or Combi Boilers

Check that the pressure dial on your boiler is set to around 1 if you suddenly have low hot water pressure. A water leak can also cause low water pressure. The owner’s manual that came with your boiler should have instructions on how to reset the pressure, otherwise, it may be a good time to call in an expert.

Stuck Ball Valve Float – Open Vented Boilers

Water may not be able to circulate around your system if you have an open vented system boiler, one that has an additional water tank. As this is usually in the loft, accessing it isn’t always easy but if you can do so safely, gently try to free the ball float valve arm.
