OUR METHODOLOGY
Hot water systems and repairs
Choosing the right system
If you’re replacing or upgrading, we help you choose the right system for your household size, energy source and budget. We install gas continuous-flow and storage, electric, solar and heat pump systems — and explain the running costs and rebates that come with each.
Supply & installation
We supply and install new hot water systems to current standards, and can usually complete a changeover the same day to keep disruption to a minimum. Correct sizing and installation are what keep a new system efficient and under warranty.
Repairs & parts
For an existing system, most issues are a straightforward repair — a faulty pilot light or gas control valve, a leaking pressure-relief (PTR) valve, or a worn element or thermostat. We carry common parts for all major brands, so we can often restore hot water the same day.
Servicing, compliance & efficiency
Regular servicing extends a system’s life and keeps it efficient, and all gas work meets Energy Safe Victoria requirements. An ageing system runs less efficiently and pushes up energy bills, so where it makes sense we’ll flag when a new system will actually save you money.

FAQS
Hot water questions
Hot water repairs start from $160 + GST. The final price depends on the system type and the parts required, which we confirm with you before starting. If the system is beyond economical repair, we’ll explain your replacement options and price those clearly too.
A new system is priced per unit and installation, so it depends on the type and size you choose — gas, electric, solar or heat pump. We’ll recommend the right option for your household and give you a clear, upfront price before any work starts.
It depends on your household size, energy source and budget. Continuous-flow gas suits smaller spaces wanting endless hot water; solar and heat pump systems cost more upfront but run cheaper and may attract rebates. We’ll talk through the trade-offs and recommend the best fit.
Usually, yes. We carry common parts for all major brands, so most repairs are done on the first visit, and we can often supply and install a new system the same day. Call early in the day for the best chance of a same-day booking.
We install and service all major Australian brands, including Rheem, Rinnai, Aquamax, Dux, Vulcan and Bosch. If you have a preferred brand we don’t normally stock, let us know and we’ll arrange to order and install it for you.
It depends on the system’s age and the fault. Units under about ten years with an available part are usually worth repairing. Older systems, tank leaks or repeat faults often point to replacement — and a newer system can lower your energy bills. We’ll give you an honest recommendation.
