Gas hot water

Also called a gas califont, tankless hot water, endless hot water, on-demand hot water, or Infinity hot water, a gas hot water system has many great advantages.

Conversions & Gas Changeovers in Tauranga

As certified plumbers and certified gasfitters, Eco Plumber & Gasfitter are perfectly suited to the job of installing a gas hot water califont. We’ll work with you to determine the size and system that best matches your budget, water flow requirements, and gas availability.

Our efficient and competitively-priced gas hot water conversion service has proven to be extremely popular.

We aim to make the job seamless for you, from the first phone call right through to job completion and certification. If necessary, we’ll coordinate with an electrician and book LPG bottles so everything is ready to go on changeover day.

Converting Hot Water from Electric to Gas

There are many good reasons our customers request a changeover from a conventional electric hot water cylinder to a gas-powered system. The issues with electric hot water cylinders include:

  • Running out of hot water
  • Outrageous electricity bills
  • They’re costly to replace
  • They take up valuable space in your home

Gas hot water califonts are the most popular replacement for old electric cylinders.

For a start, they have lower running costs because with gas, you only pay for the heating that you use at the time. Because gas systems are tankless, water isn’t sitting around in a tank cooling down and being constantly reheated.

Another benefit to not having a hot water cylinder (tank) is that there is much less pressure drop in the system, meaning better water pressure at your showerhead or sink.

Gas califonts and tankless water heating systems instead of traditional electric hot water cylinders have the advantage of never running out of hot water.

We recommend the Rinnai Infinity califont for its outstanding energy efficiency, reliability and quality, but we’re happy to suggest another brand or model if you prefer.

Converting from Solar Hot Water to Gas

Another common reason we’ve seen for converting to gas hot water, unfortunately, is to step away from a failed solar hot water system. Solar hot water systems can be quite expensive to repair, require constant maintenance, and in the past, they haven’t delivered the level of performance one might expect.

A modern solar hot water system, designed and installed by Eco Plumber & Gasfitter, is viable, cost-effective and great for the environment, but a gas califont is undeniably cheaper to install in terms of up-front costs.

No matter your need to switch to gas, Eco Plumber & Gasfitter are your trusted Master Plumbers & Gasfitters servicing Tauranga, Mt Maunganui, Papamoa and the Bay of Plenty.

Gas califonts and tankless water heating systems instead of traditional electric hot water cylinders have the advantage of never running out of hot water.


We recommend the Rinnai Infinity and the Rheem Integrity. These are cheaper to run than a straight electric hot water cylinder.


Gas hot water systems produce fewer emissions than electricity and heat water twice as quickly at 1/3 of the cost.

Only the best quality plumbing, gas and solar.

We wish to acknowledge the awesome service provided right before Christmas Eve. Very grateful for your willingness to accept the job and get it done – which meant our son and family could enjoy a well-deserved holiday with running water!!! Please pass on our appreciation to the staff as well. We will be recommending your business.

We have had Dale to our place three times - underfloor heating problems, gas hot water issues and a stove service. Each time he arrived at said time and explained everything as he fixed the issues. Great communication and would highly recommend. Thanks.

I booked Eco Plumber to relace a shower rose. Due to a change with one of their appointments. They came the same day I booked them. Brilliant service. Prompt. Took all the discarded bits with them. Very fair charge. I will use their service again.
