Frequently Asked Questions

  • Can extreme weather affect my hot water system?

    Hot and cold temperature extremes can place added strain on your hot water system, particularly on outdoor units exposed to the elements. UV exposure can degrade pipework and fittings over time, while cold snaps can cause pipes to contract and increase pressure on ageing components. Periodic inspections help identify weather-related wear before it develops into a larger problem.

  • What's the best hot water system for a rental property?

    Electric storage systems are a common choice for rental properties due to their lower upfront cost and straightforward installation. That said, gas and heat pump systems can offer better long-term running costs, which may be worth considering if you're managing the property long term. The right choice ultimately depends on the property's existing setup and your priorities as an owner.

  • How do I maintain my hot water system between services?

    Keep an eye on the area around the unit for any signs of moisture, corrosion or unusual odours. Periodically testing the pressure relief valve — by briefly lifting the lever to check it releases and reseats properly — is also worthwhile. Outside of these basic checks, it's best to leave internal components to a licensed plumber during a scheduled service.
