Which hot water service is best for you?

Updated: Jun 30

What's the best hot water system?

When looking at hot water services, there are many things to consider; installation costs, running cost, location of pump, reliability, type of use and energy efficiency.

What are the options?


Gas hot water systems are the most energy efficient option as they only heat water when it is needed, are cheaper to run and they produce less green house gas emissions. They have higher installation costs than electric systems. They require connection to gas mains and must be located outside.


Electric hot water services are the most expensive to run. Some systems heat water in off-peak times to reduce costs, however this water needs to last for the rest of the day. They are less environmentally friendly than gas or solar hot water services. They can be located indoors and have a low upfront installation cost.


Solar hot water services have the highest upfront installation costs. However, solar systems can decrease your hot water systems energy consumption and subsequently keep your electricity bills very low. These system substantially reduce your carbon footprint.

Solar hot water systems rely on direct sunlight and need to use back up gas/electric systems on overcast days.

Heat Pump

Heat pump hot water services are another energy-efficient system - their long term energy costs are low, however upfront installation costs are high. A heat pump hot water system relies on the heat from either the ground or air around it to heat water, meaning it really needs to be used in warmer climates to work effectively.

Instantaneous vs Storage?

Is an instantaneous or a storage hot water system best for your home?


Instant hot water is a continuous system that heats the water as it is needed, it does not store water, making them more energy efficient. Installation costs can be high, depending on your home. These kinds of options are not connected to an off-peak tariff system, on-peak running costs can be quite high.


Storage hot water systems store the heated water for use. Once the tank is empty, it tajes time to refill and heat the water again. These hot water systems are generally cheaper and easier to install, however they use a lot of energy to ensure the stored water at the right temperature and are therefore not very energy efficient.
