IS Electric or gas hot water best?

There are so many options to consider when it comes to gas vs electric hot water, which is why we've put together a comparison of electric hot water cylinders vs gas hot water cylinders vs gas continuous flow hot water to help you decide which option might be right for you.

Hot water is something we all expect to have, but often take for granted. We don’t tend to give hot water systems much thought until it’s time for repairs or an upgrade. If you are considering upgrading or replacing your hot water cylinder, finding the right information can be difficult.

There are several factors to consider when it comes to choosing a hot water system for your household.

  • How much water do you typically use?
  • How large is your household?
  • How many bathrooms do you have?

With so much technical information out there, it’s hard to know what is right for you. Topline’s team of licensed plumbers and gasfitters are trade specialists. We are available to talk you through your options, providing expert advice and practical solutions based on your individual requirements.
