When choosing a water heater for your new home or during a renovation, consider the following tips:
1. Choose an instantaneous water heater over a storage water heater as it is more energy efficient. If you prefer a storage water heater, choose a capacity that meets your needs.
2. If your apartment has access to the gas network, consider installing a gas water heater over an electric storage water heater.
3. If space and budget permit, consider an electric heat pump water heater. It is more energy efficient than an electric instantaneous and storage water heater as less electricity is used to transfer heat from the ambient air to heat water instead of generating heat directly.
4. If you have access to roof space (e.g. living in landed property), consider installing a solar thermal water heater as an environmentally friendly option.
Did You Know? A family of four using an electric heat pump water heater may reduce energy costs compared to an electric instantaneous and storage water heater.
Notes to Tips:
- Assumed electricity tariff of $0.299 per kWh and gas tariff of $0.247 per kWh.
- Savings are computed based on a water heater study commissioned by NEA in 2019.
- Assumed water heater lifespan of 10 years.
- The energy cost and performance of solar thermal water heater systems depend on weather conditions, insulation of storage tanks, and how they are installed and operated.
