Continuous Flow Hot Water

Why Choose A Califont?

A califont (continuous flow gas hot water heater) heats water on demand as it flows through the unit. There’s no storage tank, no standby heat loss, and no running out of hot water mid-shower.

Endless hot water – Heats continuously, so you’ll never run out. No more timing showers around the rest of the household.
Energy efficient – You only pay to heat the water you actually use. No tank burning gas all day keeping water warm.
Compact – Mounts on an external wall and takes up almost no space compared to a traditional cylinder.
Long lasting – A well-maintained califont typically lasts 10 to 15 years, with quality brands like Rinnai and Rheem often running trouble-free for even longer.
LPG and natural gas compatible – Whether you’re on town gas or LPG bottles, we install califonts to suit.

What's Involved In A Califont Installation?

A califont installation involves gas, plumbing, and electrical work, all of which need to be done to code. Here’s what the process looks like:

Site assessment

We check your gas supply type, water pressure, ventilation clearances, and the best mounting location for the unit.

Choosing the right unit

Based on your household size, number of bathrooms, and hot water usage, we recommend the right brand and model.

Installation

We connect gas, water, and electrical (most califonts need a standard power point for ignition and controls), then test the full system before signing off.

Compliance certificates

We issue a Certificate of Compliance (CoC) and Gas Safety Certificate (GSC) on completion. Every job, no exceptions.

A straightforward replacement can usually be completed in 3 to 4 hours. New installations where gas lines need to be run can take a full day.

Common Units We Replace

Our gasfitters regularly replace older califonts that have reached end of life, including:

If your unit is on this list or a similar model from the same era, it may be nearing the end of its useful life. We can assess whether a repair or full replacement is the better option.

 Trustindex verifies that the original source of the review is Google. Citywide Plumbing provides a reliable, friendly, honest and trustworthy service. My relationship with them extends back decades. While at the more expensive end of the plumbing services scale, the quality and consistency of their work is worth paying more for. I highly recommend them for all your plumbing needs.

 Trustindex verifies that the original source of the review is Google. I would give 6 stars if I could! We had a fault with our waste water pump and the control switch and called a number of plumbers, all of whom referred us to Citywide Plumbing. They were on the scene within 20 minutes and had given us a breakdown of what went wrong and how they'd fix it. They provided a quote the next day and helped us work with our insurance. Once the parts had arrived Sean got to work and did an excellent job helping us get our plumbing in order. Josh and Sean were a pleasure to deal with from the get go and were professional, courteous and were very knowledgeable - making them an expert in what they do. Wishing everybody at Citywide plumbing all the best, you guys rock!

 Trustindex verifies that the original source of the review is Google. Fantastic service. Pump started making some noise, I ignored it for a couple of weeks and the organised the team to come and look at it a couple days later. Pump died completely that evening, they came out the following morning to rescue us with a loan pump. Took a look at the old one and showed it was done, installed a new one for me. Highly recommend the Citywide team.

Frequently Asked Questions

How much does a califont installation cost?

The cost depends on the brand and model, the complexity of the installation, and whether additional gas line or electrical work is needed. Contact us for a free quote, we'll assess your setup and provide a clear price before any work starts.

Can I upgrade from a hot water cylinder to a califont?

Yes, this is one of the most common jobs we do. We remove the old cylinder, run gas and water lines to the new califont location, and install the new unit. Your taps and shower may operate at different pressure afterwards, which we'll talk you through before the work starts.

What size califont do I need?

As a general guide: a 16-litre unit suits a small home with one bathroom. A 20-litre unit works for 2 to 3 people. A 26-litre unit is recommended for larger families or homes with two or more bathrooms.

Will a califont work during a power cut?

No. Modern califonts use electronic ignition that requires electricity. If you experience frequent power outages, this is worth considering when choosing your hot water system.
