Winter has certainly arrived throughout the South West and a South West winter certainly brings low temperatures in the evening, overnight and early mornings. Free flowing water in our homes is a resource most of us take for granted and hot water a luxury most homes and businesses can’t do without. While having no hot water at any time is an inconvenience, inconsistent hot water during winter is not something we want to endure.

While your hot water may be hot when you first turn the hot water tap on, if it’s not staying hot it indicates there is an issue and it’s time to have your hot water system inspected and repaired. Read on to learn a few reasons why your hot water is not staying hot including:

  • A build-up of residue
  • Corrosion
  • Your hot water system is leaking

A build-up of residue

Whether your hot water system is solar, electric or gas, they function in the same way in as they heat water, minerals separate and over time cause a build-up of residue. The more residue, the harder your hot water system must work to keep your hot water at the right temperature.


Although hot water systems are designed to last, as with all appliances in the home they will eventually need replacing. If you have had the same hot water system for many years and notice rust on the system or surrounding pipes it is a good indicator corrosion has set in and it’s time to consider a replacement.

To regulate pressure in the water tank, ensuring it doesn’t over pressurise, hot water systems can release a small amount of water. This is normally more evident in the summer months. If your hot water system releases more than the occasional drip or there is water leaking or pooling below or near your hot water system, this is a warning sign there is an issue.
