Common questions

How long does a hot water system last?

Storage tanks typically last 8 to 12 years. If yours is leaking from the tank body rather than a valve, replacement is almost always the answer.

Are heat pump hot water systems worth it?

They cost more upfront but use around a quarter of the electricity of a resistive tank, and state rebate schemes can close most of the price gap.
