How To Choose The Best Hot Water System For Wellington Homes

​​Hot water systems are an essential part of any home. Choosing a hot water system isn’t just about finding the most cost-effective and energy-efficient option, it’s also about finding the most suitable system to meet your specific needs. 

Hot Water Cylinders

With a variety of types of hot water systems available, it is important to understand the difference between them and what type best fits your needs. The most common type of hot water system is a Hot Water Cylinder. This system stores hot water in a tank and then circulates it through your home’s plumbing system. These systems are usually powered by electricity, gas, or oil and can be installed either inside or outside your home. 

One of the main benefits of these systems is that they typically provide a large amount of hot water, making them ideal for households with multiple bathrooms. Gas hot water cylinders in particular typically run on natural gas. They burn gas to heat the water in an insulated tank to a temperature set by a thermostat. Gas hot water cylinders are less efficient than gas continuous flow systems, but they will work during power cuts.

Solar Hot Water System

Solar hot water systems are another option that can be used to reduce energy costs. These systems use energy from the sun to heat water, which is then stored in a tank and circulated through your home’s plumbing. The main benefit of these systems is their reduced energy costs, but they can also be more expensive to install than other types of hot water systems. 

Heat Pump System

Heat pump systems are an increasingly popular hot water system. These systems use electricity to transfer heat from the air or ground to the water in the tank, which is then circulated through your home’s plumbing. Heat pump systems are generally more efficient but tend to require more maintenance than other types of hot water systems.

Continuous Flow System

Another popular hot water system is the on-demand or tankless system. These systems heat water as it is needed and does not require a storage tank. This allows for an unlimited supply of hot water, which is great for homes with multiple bathrooms and large families. On-demand systems also tend to be more energy efficient than storage tank systems, reducing your energy costs. 

An example of this type of hot water system is the Rinnai Infinity A-Series continuous flow hot water system. These systems are suited for residential applications, with the water heaters producing endless hot water, and unlike electric cylinders, are energy efficient as they only heat water when you need it. The Rinnai Infinity also has a pause button, so you can save even more energy if you don‘t need hot water for a period of time, helping to save money and reduce your carbon footprint.

There are five models to choose from depending on your hot water needs. Model numbers represent hot water capacity, for example, the A26 produces 26 liters of hot water per minute at a 25° Celsius rise.


It is important to research and compare the different types of hot water systems on the market before installing one in your home.
