Call Now — We'll Sort It 0800 322 322Every Auckland home needs reliable hot water, and choosing the right system makes all the difference to your comfort, energy bills, and water pressure. Whether you have an older home with a traditional hot water cylinder or you are considering upgrading to a modern continuous flow unit, Water and Gas Worx can help you find the best solution for your household.
New Zealand homes typically run one of two main hot water systems: a stored cylinder (either low pressure or mains pressure) or a continuous flow gas unit. Each has its own advantages depending on the size of your household, the age of your home, and how many bathrooms you need to supply. We install, repair, and replace all types across Auckland.

Hot water cylinders store a set volume of heated water (typically 135 to 300 litres) ready for use. They suit most households and are the most common system in New Zealand. Electric cylinders are straightforward and affordable to install, while gas cylinders heat water faster and cost less to run.
Continuous flow systems heat water on demand as it passes through the unit. There is no stored tank, which means you never run out of hot water. These units are compact, energy efficient, and ideal for homes with high hot water demand or limited space for a cylinder.
The right choice depends on your household size, existing gas supply, budget, and how many showers run at the same time. If you are weighing up the options, read our detailed comparison guide: Hot Water Cylinder vs Continuous Flow — Which Is Best?
If your hot water has stopped working or your cylinder is showing signs of trouble, we can diagnose and fix the issue quickly. These are the most common problems Auckland homeowners call us about:
Woke up to cold water? We diagnose and fix the cause — elements, thermostats, gas valves, and pilot lights.
Water pooling around your cylinder usually means it needs replacing. We handle removal and new installations.
Other issues we deal with regularly include fluctuating water temperature, discoloured hot water, rumbling noises from the cylinder, and slow hot water recovery. If something does not seem right, give us a call and we will sort it.
