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 types of hot water systems are available, and how do they work?
Hot water systems are typically gas, solar or heat pump. Gas systems heat water using a burner, either as a continuous flow or in a storage tank. Solar hot water systems use energy from solar panels, storing heated water in a tank. Heat pump systems extract heat from the air, even in cooler climates—and transfer it to the water.
How do I choose the right hot water system for my home?
To choose the right hot water system, consider factors like household size, hot water usage, climate available energy sources and budget. For instance, a solar system is eco-friendly but has higher upfront costs, making it suitable for sunny areas with high usage. Gas systems provide instant hot water but need a natural gas connection. Consulting a professional installer can help determine which system matches your needs.
How often should hot water systems be serviced?
Most experts recommend servicing a hot water system every 1-2 years to ensure efficiency and prevent breakdowns. Regular maintenance includes checking for sediment buildup, inspecting the heating element or burner, testing the thermostat and ensuring there are no leaks or rust. Routine servicing helps extend the system’s lifespan and reduces energy costs by maintaining peak performance.
