Gas vs Electric Hot Water in NZ: Which Is Better?

When it's time to replace your hot water system, the big question is gas or electric. Both have their place — here's an honest comparison to help you choose.

Electric hot water cylinders

The most common NZ system: a tank heated by an element. Pros — simple, works anywhere, cheap to install, pairs well with night-rate power and solar. Cons — runs out if you use it all, standing heat loss from the tank, and low-pressure versions give weak flow.

Gas (califont / continuous flow)

A gas califont heats water on demand. Pros — never runs out, efficient (no tank loss), compact. Cons — needs a gas supply (natural gas or LPG), flow rate limits very high simultaneous demand, and must be installed by a registered gasfitter.

Which should you choose?

If you have gas available and hate running out of hot water, a califont is hard to beat. If you're all-electric (or want to pair with solar/night rates), a mains-pressure cylinder is the sensible choice. We'll look at your supply, household size and budget and give you a straight recommendation.

How we can help

FAQ

Quick answers

Is gas or electric hot water cheaper to run?

It depends on your gas and electricity prices and usage. Gas continuous-flow avoids tank standing loss; electric can be very cheap on night rates or with solar. We can compare for your situation.

Can I switch from electric to gas hot water?

Yes — many homes move to a gas califont for endless hot water. It needs a gasfitter and suitable gas supply, which we can arrange.
