Hot Water Systems in Marrinup

Hot water systems in Marrinup

In Marrinup, more locals are swapping old gas and electric tanks for modern, energy efficient hot water systems that actually suit the way they live. With an average household size of around 2.4 people and most homes being separate houses on decent blocks, there is plenty of roof space and yard room for a solar hot water system or a compact heat pump hot water system. Power prices keep creeping up, and with many households on fixed incomes and a median household income of about $1,383 a week, locking in lower running costs from your hot water system is a simple, sensible step.

Marrinup’s sunshine is a real asset. The Del Park weather station shows mean daily solar exposure of about 18.4 MJ/m², which works out to roughly 5.1 kWh/m² of solar energy per day across the year. That strong solar resource supports both a solar hot water heating system and a heat pump hot water system, especially when paired with rooftop solar. For many homes, upgrading from an older gas or resistive electric hot water system to a modern energy efficient hot water system can slash the energy used for hot water, which is often one of the biggest loads in the house.

Across the 6213 postcode there are 232 occupied private dwellings and a high share of homes that are owned outright or with a mortgage. That makes it easier for owners to invest in upgrades like a new hot water installation. Families and older couples alike are starting to look at options like heat pump vs solar hot water, comparing running costs, noise levels and space. With Marrinup’s climate and block sizes, both a roof‑mounted solar hot water installation and a quiet, outdoor heat pump hot water installation can work well.

When you look at system sizes and savings, the right choice depends on how you use hot water. A typical three‑bedroom home with two to four people might consider a 250–315 litre heat pump hot water system, or a similar‑sized solar hot water tank replacement with roof collectors. Brands like Rheem and Rinnai are popular for both solar and electric hot water installation, while Sanden and Stiebel Eltron are often chosen by those chasing the best heat pump hot water system and the most efficient hot water system overall. Many Marrinup homes already have rooftop solar, so a modern electric hot water system on a timer or diverter can soak up excess solar and turn it into almost free hot water.

Average annual bill savings from a smart upgrade are substantial:

• Old electric to heat pump hot water system: save roughly $350–$700 per year. • Gas to heat pump hot water system: save roughly $250–$600 per year. • Gas to solar hot water system: save roughly $200–$550 per year. • Old electric to modern electric hot water system with solar: save roughly $200–$500 per year.

Looking at recent activity, there have already been 123 efficient hot water systems installed in the Marrinup 6213 area, including both heat pump and solar hot water systems. Installations grew strongly through the mid‑2000s, peaking around 2004–2005, and while numbers eased off for a while, there has been steady interest again in recent years, with new systems going in every year from 2018 through to 2025. This shows a clear local shift towards electrification, lower running costs and more reliable, low‑maintenance hot water repair and replacement options.

Hot Water Rebates, Tariffs & Savings

Across Marrinup WA, more people are asking whether to choose heat pump vs solar hot water, or even solar hot water vs electric hot water, when they replace an ageing unit. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible solar hot water installation and heat pump hot water installation, effectively giving you an upfront discount off the solar hot water price / cost or heat pump hot water price / cost. On top of that, WA programs and retailer offers can work like a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate, depending on what is available at the time.

These hot water rebate WA options can trim the installed hot water system price / cost by a significant percentage, cutting the payback period to just a few years, especially if you also have rooftop solar. For many Marrinup households, switching to an energy efficient hot water system can save hundreds of dollars a year on power bills. Using timers or solar‑diversion controls to run your electric hot water system during the middle of the day makes the most of your solar and keeps ongoing costs low. For anyone still on gas, comparing electric hot water vs gas hot water is now firmly tilting towards going all‑electric, thanks to better tariffs, lower maintenance and improved technology.

When it comes time to replace an old unit or you need hot water repair, it is worth thinking beyond a like‑for‑like swap.
