What are heat pumps?


What are the benefits?
* Save money over time: Heat pump water heaters use less energy than a conventional water heater which may lower your energy bills
and save you money over time. Heat pumps also allow you to preheat water during times of the day when power is cheaper and store the hot water for use during peak times when costs are higher.
* Longer lasting: Heat pump versions have a lifespan of around 13-15 years, while conventional versions typically need to be replaced every 8-12 years.
