Frequently Asked Questions

  • What areas do you service?

    At FNQ Hot Water, we proudly serve the entire Cairns, Mareeba, Atherton and Port Douglas region, catering to homeowners, body corporates, commercial, and industrial clients.

  • What are the benefits of solar hot water systems?

    Solar hot water systems use renewable energy, reducing reliance on fossil fuels and lowering utility bills. They are environmentally friendly and ideal for sunny regions, where they can meet up to 90% of hot water needs. Though initial installation costs are high, government rebates and long-term energy savings make them a good investment for eco-conscious homeowners.

  • How can I tell if my hot water system is leaking?

    Common signs of a hot water leak include pooling water near the tank, rust or corrosion on the tank and an unexpected increase in your water bill. Leaks can occur in various parts, including valves, connections and the tank itself. Prompt repair or replacement is essential, as leaks can lead to water damage and reduced system efficiency.

  • What is a heat pump hot water system, and how does it work?

    A heat pump hot water system extracts heat from the air to warm the water, similar to how a refrigerator works but in reverse. It is highly energy-efficient, using up to 60% less electricity than conventional electric water heaters. Heat pump systems are effective in moderate climates and can be supplemented with electric boosters in colder areas.
