How to Choose the Right Solar Hot Water System

February 24, 2021

Hot water systems are an essential element of all homes in Coffs Harbour.

Whether you’re in the market to upgrade your existing system or you are looking for a brand new hot water system, North Coast Power and Water can help.

We are the experts in solar hot water systems in Coffs Harbour and can help you choose the perfect system type and size for your home.

Here’s our advice on how to find the right size hot water system for your home.


Hot Water Tank Size

Again, consider the size of your family and how much water you use.

If you live alone, obviously, you’ll need a smaller tank than if you have several kids at home who shower and use water at the same time every day.

As a general rule of thumb, you want to oversize your hot water tank a bit to cover the days of overcast weather when you aren’t getting the solar energy to heat it.

If you go slightly larger than you need you may get an extra day before the electric or gas booster has to come on.

How Much Water is Used

Another factor to take into account is how much water you use.

Do you have to bathe several kids each day? Do you do a lot of cooking with water?

The more water you use on a daily basis, the bigger your system needs to be.

The most common size for solar hot water is 315Ltrs.  A 250L system gets less rebate so does not generally save much for the homeowner.

A 400Ltr system is generally reserved for households with more than 4 x people or high hot water users.

Other Considerations

There are a few other things to think about when choosing your hot water system.

Do people take showers simultaneously in separate bathrooms? If so, you’ll need a larger hot water tank so no one ends up having a cold shower.

Washing clothes on hot water also requires a larger tank, as does filling a large bathtub several times per day.

The number of times you run the dishwasher every day also plays a role.

No matter the size of the hot water system, North Coast Power and Water can help you find the right solar hot water systems in Coffs Harbour for your needs.
