Overview

Efficient hot water for your home

Hot water is one of the biggest energy users in a home. Home Energy Saver offers two efficient options: a heat pump water heater, which pulls warmth from the surrounding air like an air conditioner in reverse; and a solar water heater, which uses collectors on your roof to heat water from the sun. Both use far less energy than a traditional electric storage system.

Both store hot water in an insulated tank and include a booster or backup for cloudy days or busy periods. A heat pump does not need roof space, while a solar water heater makes direct use of the sun. It is one of the upgrades you may be able to choose through Home Energy Saver.

Not sure which suits you? Your home assessment confirms the right system and size before anything is installed.

suitability

Is it right for your home?

An efficient hot water system may suit your home if you:

  • are replacing an old, broken or inefficient hot water system
  • want to reduce the energy used to heat your water
  • have solar and want to heat water during the day, or have roof space and sun for solar collectors

A heat pump does not need roof space, while a solar water heater needs enough unshaded roof and sun. Your home assessment confirms the right system for your home before anything is installed.
