When a heat pump makes more sense
If you're on a standard tariff, have solar panels, have a family using plenty of hot water, or plan to stay in the home for years, a heat pump is usually the better long-term choice.
When electric makes more sense
If you need the lowest upfront price, are selling soon, have a small household, or the only suitable position is somewhere a heat pump's noise or airflow would be a problem, an electric tank is still a good choice.
On this coast
Near the beach, choose a sheltered spot or a coastal-rated heat pump to slow corrosion. Up on the range, choose a model rated for cooler air. See heat pump hot water and electric hot water.
Common questions
Is a heat pump cheaper to run than electric hot water?
Yes. A heat pump typically uses around a third of the electricity of a standard electric storage tank for the same amount of hot water.
Is a heat pump worth it on the Sunshine Coast?
For most homes, yes. The mild climate lets heat pumps run efficiently all year, and STC incentives on eligible models reduce the upfront cost.
