Frequently Asked Questions
How long do hot water systems typically last on the Mornington Peninsula?
Salt air reduces lifespan. Electric systems average 8-12 years, gas 10-15 years, continuous flow often exceeds 20 years with maintenance.
What size hot water system do I need?
Calculate 50L per person daily, though active Peninsula lifestyles often need more. We assess your specific usage patterns for perfect sizing.
Is solar hot water worth it on the Mornington Peninsula?
Absolutely! Excellent solar exposure delivers 60-80% free hot water. Government rebates reduce costs with typical payback in 4-6 years.
Why does my hot water run out so quickly in winter?
Cold inlet water requires more heating. Your 160L tank might deliver 200L in summer but only 140L during winter. Annual flushing helps maintain capacity.
What’s the most cost-effective system for holiday homes?
Continuous flow gas excels - no standing losses between visits, instant hot water on arrival, lower maintenance requirements than storage systems.
How do I protect my system from salt air?
Annual anode checks, protective coatings, covered installation locations. Peninsula systems need anodes replaced twice as frequently as inland areas.
What are the signs my hot water system needs replacing?
Rust-coloured water, persistent leaks, rising energy bills, inadequate hot water, unusual noises. Repairs exceeding 50% of replacement cost suggest upgrading time.
