Hot Water System Options We Install
Storage Hot Water Systems
Traditional systems that heat and store water in a tank. Available in electric, gas and solar configurations. Ideal for families or properties with higher water usage.
Continuous Flow (Instant) Systems
Energy-efficient and compact. Heats water as you need it. Perfect for smaller households or those looking to reduce energy bills.
Heat Pump Hot Water Systems
Eco-friendly alternative that extracts heat from the air to heat water. Commonly installed outside.
Can a heat pump hot water system be installed indoors? In most cases, no — they require adequate airflow and ventilation, which is why outdoor installation is preferred.
