What Are The Most Common Issues That Require Boiler Repair?

Keeping your boiler in good shape is massively important for keeping your home or business property warm and more pleasant to work or live in, plus ensuring the safety of your home or business. Having a cold home or business can be uncomfortable and a broken boiler can mean dangerous gases are at risk of leaking into your home or business property. Often you will be unable to smell the gas that is leaked or notice the potentially dangerous issue that may be at danger of worsening, which a qualified heating engineer with the correct equipment will be able to detect quickly and effectively.

Regularly checking your boiler, radiators and hot water supply is important for maintaining your boiler’s health and prolonging its’ life. With over 40 years experience of boiler repairs, we have compiled a list of the common boiler problems that our customers have commonly encountered and have called out our heating engineers to diagnose and repair. These include:

  • No heating or hot water available from radiators or taps
  • Odd noises from the boiler, such as banging, whistling or gurgling
  • Pilot light has gone out or is an unusual colour
  • Thermostat is working incorrectly and not showing correct temperature
  • Low boiler pressure due to a leak or a new relief valve being required
  • Odd smell emitting from the boiler or around the property
  • Water leaking or rust appearing around boiler
  • We recommend having your boiler regularly checked, at least once a year to ensure you keep your family, employees and property safe from any dangers relating to your boiler.

This is why we are trusted time and again by our clients be they from Cardiff, Swansea or anywhere else in the South of Wales; at Eric Collier and Son we put your needs first.  Contact us today to enquire about our boiler repairs in Cardiff.
