Frequently Asked Questions about Storage Hot Water Systems

When it comes to storage hot water systems there are two types, gas and electric.

While your local energy prices will vary, typically the runnings costs of gas are cheaper than electric, while fewer greenhouse gasses are created by gas powered appliances as well. Ultimately, when comparing hot water systems the decision comes down to the home.

A gas instantaneous system is often seen as the best choice, but for a home with 4 or more people a gas storage tank could be best. You will have hot water on standby, and a larger amount ready to go for multiple users at the same time.

In terms of an electric storage unit, nowadays it is really seen as the least popular choice due to average running costs of over $1000 per year, and high greenhouse gas emissions. Despite that, some homes have no alternative so it is always best to go for the most energy efficient option.

Your storage tank should really be thoroughly serviced at least every 5 years. This will allow a professional plumber or electrician to inspect your thermostat, sacrificial anode, burner and more.

Perhaps most importantly, they can flush the system of sediment and ensure pipes are properly insulated.

You can certainly call in an expert for more common servicing, too. It is recommended you regularly flush the system every year or 2 so sediment does not build up, which could promote bacteria growth or impact the quality of water.

But if you do stick to roughly 5 years, that’s only 3 easy services throughout a hot water system’s lifetime.

On average you can expect roughly 10 years’ service from a hot water unit. The exact time will vary on how well it’s looked after, too.

If by some great miracle your system has reached the 15 year mark – or more – certainly consider an upgrade. While it is great to milk every last drop, in terms of energy efficiency there are newer systems which will save you considerable running costs.
