Looking for gas water cylinder installation in NZ? We offer gas hot water heating & cylinder install for both Rheem & Rinnai gas water heater.
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.
