5 Signs There’s a Problem With Your Unvented Hot Water Cylinder

System or regular boilers require a cylinder to store hot water and there are two types you can have; a vented or unvented hot water cylinder. Normally the latter is extremely reliable but, from time to time, they can have their issues. So here are some of the most common problems and what to look out for with an unvented hot water cylinder.

Odd Noises From Unvented Hot Water Cylinder

Water that is in the cylinder always expands when it is heated so every now and again you might hear a noise such as a normal creak or gurgle. Over time, however, this noise can increase as sediment builds up in the tank so flush your unvented hot water cylinder regularly to keep your system flowing nice and smoothly.

Dirty or Foul-Smelling Water

Discoloured or smelly hot water is the result of a high concentration of sulphates. It’s often related to the cylinder’s anode rod and means this part will probably need replacing. If you’re experiencing this issue with both hot and cold water, however, it’s possible the cylinder isn’t actually causing the problem. Check with your professional engineer just to be sure but it’s likely to stem from the mains supply.

The Water is Too Hot

A particularly dangerous fault because it means boiling water could start coming out of your taps, it’s better to get this addressed sooner rather than later to avoid any nasty incidents. If your water is hot with the temperature turned down then it could be a problem with the temperature pressure relief valve. Contact your heating engineer to replace this valve and be sure to mention any signs of boiling from within the tank itself.

None or Not Enough Hot Water

During the colder months, your system may have to work harder to heat up the water than it usually would. So the first thing you should do is check that the temperature on your cylinder is set to correct. If that doesn’t work then the cylinder might not be big enough to meet your demand. One other issue to check for is any tank leaks which could affect the overall system efficiency.

No Water Whatsoever

If there is no water at all, hot or cold, then this could be an issue with the filter. It’s usually because the mesh itself is all blocked up and causing a water obstruction. If you think this is the case you will need some help from a professional heating engineer. Please contact us to get booked in and resolve this annoying issue.
