Solar Hot Water Repairs
Leaking panels, failed frost valves, no hot water, weak pressure or a system that's stopped heating, we diagnose the real cause and fix it properly, not just patch the symptom.

Why Solar Hot Water Systems Struggle in a Melbourne Winter
Melbourne isn’t officially classed in Victoria’s frost zone, but anyone in the outer suburbs knows better. On clear, still nights, the temperature near your roof panels can drop below freezing, and that’s exactly when solar hot water systems get into trouble.
When water inside the rooftop collectors freezes, it expands. That expansion is enough to crack copper risers, split a manifold or burst a panel, damage that’s often impossible to repair and expensive to replace. Most systems are fitted with a frost protection valve to prevent this, but those valves wear out, and when they fail, the freeze damage follows.
It’s worst in Melbourne’s cooler, more elevated pockets, Melton, Sunbury, Craigieburn and Whittlesea in the north and west, the Dandenong Ranges and Yarra Valley in the east, and the Macedon Ranges, but we see frost-related leaks right across the metro every winter.

Solar Hot Water Frost Damage & Leaking Repairs in Melbourne
This is the part most plumbers skip, and it’s the part that matters most once the cold sets in. If you’ve spotted water running off your roof from the solar panels, here’s what’s actually happening and what to do about it.
Is it your frost valve, or a cracked panel?
These are the two most common causes of solar hot water leaks. A frost valve may drip on very cold mornings, that's normal. Constant leaking, spraying, or leaks in mild weather usually mean the valve has failed or a panel has cracked from freezing.
Frost valve failure
Frost valves typically last 1–2 years before wearing out. A failed valve can waste water, increase bills, and leave your system unprotected. Early replacement is usually a quick, affordable fix.
Cracked panels from frost damage
If freezing occurs, panels can crack internally and leak when they thaw. These collectors usually can't be repaired, so we'll assess whether bypassing, repairing, or replacing the system is the best option before any work begins.
Leaking right now? Do this first.
Shut off the isolation valve on your hot water system (the tap on the cold water line feeding the unit). If you can't find it, turn off the water at your mains meter. That stops water from running off your roof. Then call us, don't climb onto a wet, frosty roof yourself.
Emergency Solar Hot Water Repairs Melbourne

How We Repair Solar Hot Water Systems

Find the Real Cause
We inspect the panels, frost valve, tank, booster and pipework to work out exactly what's failed, not just where the water's coming out.

Fix It or Quote It Straight
Where it's a repair, we carry the common parts to fix it on the spot. Where it's a replacement, you get a clear, itemised quote before any work begins.

Test and Protect for Next Winter
We test the system end-to-end and check your frost protection is doing its job, so you're not back in the same spot next cold snap.

FAQs – Solar Hot Water Melbourne
Why is my solar hot water system leaking on the roof?
In winter, it’s most often the frost protection valve doing its job, dripping to stop the panels freezing. If it’s dripping only on frosty mornings, that’s normal. If it’s leaking constantly, on mild days, or spraying water, the valve has likely failed, or a panel has cracked. Either way, it’s worth a quick inspection before it wastes water or worsens.
How much does a solar hot water frost valve replacement cost?
The valve itself is relatively inexpensive; the main cost is the call-out and roof access. It’s a far cheaper fix than the cracked panels you’ll face if a failed valve goes unnoticed, which is why we recommend replacing worn valves before winter.
Can a cracked or frost-damaged solar panel be repaired?
Sometimes, but often not. Once water freezes inside a collector and splits the internal pipework, the panel usually needs replacing. We’ll assess it on site and, if it can’t be saved, talk you through a panel bypass or a system replacement.
How quickly can you repair my solar hot water system in Melbourne?
For urgent jobs, leaks, no hot water, or frost damage, we offer same-day bookings across Melbourne and respond as fast as we can.
Do you repair all brands of solar hot water systems?
Yes. We service and repair Solahart, Rheem, Edwards, Chromagen, Dux, Apricus, Hills, Rinnai and others, whether or not we installed the system.
Should I repair or replace my solar hot water system?
It depends on the system’s age and what’s failed. A valve, sensor or booster fault is usually worth repairing. Cracked panels, a leaking tank, or a system past 10–15 years often makes replacement the better long-term value. We’ll give you an honest recommendation either way.
How often should a solar hot water system be serviced?
Most manufacturers recommend a service every 5 years, but a quick frost-protection check before winter each year is cheap insurance against a burst panel. Regular servicing is the single best way to get past 10 years out of your system.
What areas around Melbourne do you cover?
We service solar hot water systems right across Melbourne, including the outer and elevated frost-prone suburbs in the north, west and east, where frost damage is most common.
