Frequently Asked Questions about Hot Water System Replacement

The servicing frequency for your hot water system depends on the manufacturer’s recommendations, as each system has components requiring maintenance at different intervals. Regular checks ensure smooth operation and help prevent costly repairs.

Here’s a general guide for common components:

  • Pressure relief valve: every 6 months
  • Expansion control valve: every 6 months
  • Pressure limiting valve: every 3 to 5 yearsTempering valve: every 3 to 5 years
  • Isolation non-return valve: every 3 to 5 years
  • Sacrificial anode: every 3 to 5 years
  • Heating element: every 3 to 5 years
  • Thermostat: every 3 to 5 years
  • Thermocouple: every 3 to 5 years

Following these guidelines keeps your system in top condition, extending its lifespan and ensuring a steady supply of reliable hot water.

Deciding whether to repair or replace your hot water system depends on its age and condition. Most systems last 10 to 15 years, so replacement is often the smarter choice for older units.

Newer systems are more energy-efficient, saving you money on running costs. Upgrading to a continuous flow system or switching to gas or solar can further boost performance and savings.

If your system is relatively new, a repair might suffice, provided the issue isn’t severe. For older units, replacement can save you from frequent breakdowns and rising energy bills. An experienced plumber can help you make the best decision for your situation.
