Enjoy huge savings on your power!

Most houses can have their old cylinder replaced with a tankless and continuous gas hot water system (Califont), and the benefits can be massive for your wallet. Our range of systems are some of the best performers in New Zealand conditions and best of all, this type of conversion can usually be done in less than a day! You also won’t need a building consent, as Gasfitters are self-certifying. Easy!

Rinnai Gas Water Heaters

Boasting precision engineering from Japan, Rinnai gas instantaneous hot water systems are affordable and compact, with superb functionality. A Rinnai gas water heater is a breeze to maintain, offering money-saving energy efficiency combined with convenience and flexibility of installation. Here are three popular Rinnai models to choose from. 

Control at your finger tips!

A controller is not essential for Gas, but is worth considering if you want the benefits of complete temperature control and added features, like having it run you a bath and telling you when it is ready! You use your gas hot water unit more efficiently as less gas is required to heat water to 40 °C (typical shower temperature) than at 55 °C (default temperature without controllers). Plus, there is added peace of mind if you have young children in the house, you can pre-set the temperature to a child-safe level for the period while you are filling the bath.
