How much does a new hot water system cost?
The cost of a new hot water system depends on the type and size. Electric storage systems are the most affordable upfront, while heat pump and solar systems cost more but save on running costs and may qualify for rebates. Call SunCity Hot Water on 1300 728 122 for an all-inclusive supplied-and-installed quote on the Rheem Tankpak External TPE01 - 340.
How long does a hot water system last?
Most hot water systems last 8–12 years. Electric storage systems typically last 8–10 years, while heat pump and solar systems can last 15 years or more with regular servicing.
What size hot water system do I need?
As a guide, 1–2 people suit 125–160L, 3–4 people (a family of four) suit 250–315L, and larger households suit 400L. Continuous-flow gas units are sized by hot water flow rate instead. SunCity will help size the right system for your household.
