Edwards Solar Hot Water Repairs – Gold Coast to Brisbane

Fast, reliable repairs for Edwards solar hot water systems.

If your Edwards solar hot water system is leaking, only producing lukewarm water, or the booster has stopped working, you’re in the right place.

Edwards was one of Australia’s most respected solar hot water brands, known for stainless steel roof-mounted and split systems with high-efficiency solar collectors. The brand has since been absorbed by Rheem Australia, and some models are no longer made — but there are still thousands of Edwards systems on roofs right across the Gold Coast.

At Todd’s Plumbing & Electrical, we specialise in servicing, repairing and, when necessary, replacing Edwards solar hot water systems, so you can keep enjoying reliable solar hot water instead of cold showers.

Edwards Solar Hot Water Systems We Service

Edwards L Series – Roof-Mounted Stainless Steel (Close-Coupled)

We work on most existing residential Edwards solar models, including:

  • Storage cylinder and solar collectors mounted together on the roof

  • Thermosiphon design – as water heats, it rises into the tank and cooler water drops into the collectors

  • Cylinders made from marine-grade 316 stainless steel, marketed as low-maintenance and anode-free

  • Electric or gas boosting options

Edwards LX Series – Indirect / Closed-Circuit

  • Stainless steel tank with internal heat exchanger

  • Collectors and heat exchanger form a closed circuit, filled with heat-transfer fluid for frost protection

  • Suited to colder or frost-prone areas but many units are installed in SEQ too

Edwards Split & “Solar Edwards” Systems

  • Roof-mounted collectors with a ground-level tank

  • Often branded as Solar Edwards, still using stainless steel cylinders and high-efficiency panels

  • Electric or gas boosting via in-tank elements or external boosters

Even though Edwards is now under Rheem, most parts and equivalent replacements are still available, and there are compatible Rheem / Solahart systems for upgrades.

Common Edwards Solar Hot Water Problems (and How We Fix Them)

This section is written to directly match search queries like “Edwards solar hot water not heating,” “Edwards roof tank leaking,” and “Edwards solar booster not working”.

1. No Hot Water or Only Lukewarm Water

Syptoms:

  • Showers are cold or just lukewarm

  • Hot water runs out very quickly, especially mornings and nights

Likely causes:

  • Booster element or thermostat failure in the tank – very common on older roof-mounted Edwards units

  • Tripped breaker or faulty isolator

  • Solar collectors dirty, shaded or underperforming

  • Undersized system for current household usage (family has grown, extra bathrooms etc.)

Our fixes:

  • Test the electric element and thermostat for continuity and correct operation

  • Check power supply, breakers and rooftop isolators

  • Inspect collectors for shading, dirt and damage; clean or repair as needed

  • Review system sizing vs usage and recommend practical options if the system is simply too small

2. Edwards Solar System Leaking (Tank, Collectors or Pipework)

Symptoms:

  • Drips from around the roof-mounted tank or collectors

  • Rust streaks on the roof or walls

  • Puddles under the tank or at relief valve outlets

Solar hot water specialists list leaks from tanks, pipes and connections as one of the most common issues across all brands. Edwards units use stainless steel, but that doesn’t mean they’re immune to failure — there are documented cases of L-series stainless tanks corroding through after 8–10 years, especially in harsh water conditions.

Likely causes:

  • Internal tank corrosion or weld failure (age, water quality, coastal environment)

  • Split collector headers or pipes on the roof

  • Perished seals, unions and compression fittings

  • Excessive mains pressure stressing joints and valves

Our fixes:

  • Pressure-test the system to pinpoint the exact leak source

  • Replace faulty valves, unions, fittings and short runs of copper where repairable

  • If collectors are split, recommend panel replacement or compatible alternatives

  • If the tank shell is compromised, provide repair vs replacement options (including modern stainless or glass-lined solar and heat-pump systems)

3. Booster Not Working (Electric or Gas)

Symptoms

  • Water is okay after several days of sun, but cold after cloudy weather

  • Water never gets truly hot at night, only lukewarm

On roof-mounted systems like Edwards or Rheem Hiline, the element and thermostat are located in one end of the horizontal tank, and they’re a common failure point over time.

Likely causes:

  • Burnt-out electric element

  • Failed thermostat or incorrect temperature setting

  • Tripped circuit breaker or faulty isolator

  • For gas-boosted systems, ignition or gas supply issues

Our fixes:

  • Test and replace elements, thermostats, fuses or breakers as needed

  • Verify wiring and isolators are safe and compliant

  • For gas boosters, check ignition, gas supply and error indications; repair or replace as required

  • Re-set boosting schedules so you get reliable hot water in the morning and evening

4. PTR Valve Constantly Dripping or Dumping Water

Symptoms

  • Continuous trickle from the PTR drain line

  • Occasional heavy discharge (“dumping” water) after showers or heavy use

Industry resources note that relief valve leaks are a major complaint in older solar systems, often tied to high pressure or faulty valves.

Likely causes:

  • Normal thermal expansion (small, intermittent discharge is okay)

  • Worn or scaled PTR valve

  • Excessive mains pressure with no pressure-limiting valve

  • Overheating due to thermostat or controller issues

Our fixes:

  • Measure mains and system pressures, fit or confirm pressure-limiting valve if required

  • Exercise the PTR lever and, if still leaking, replace the valve

  • Check thermostat/booster settings so water isn’t being overheated

  • Inspect tempering valve so outlet temperature stays safe while the tank runs at 60°C+

5. Edwards Roof Tank Has Failed – Repair or Replace?

Because Edwards tanks are stainless steel, many homeowners assume they will never fail; however real-world experience (and online reviews) show they can still rust through or split, particularly in certain water conditions.

Signs your Edwards tank may be at end of life:

  • Tank has visible rust or staining around welds or fittings

  • Multiple small leaks that keep returning even after repairs

  • Unit older than 15–20 years and starting to show other age-related issues

In those cases, we’ll

  • Assess whether a direct tank swap onto the existing collectors is viable

  • Price options for new stainless or glass-lined solar systems, or a high-efficiency heat pump

  • Make sure any replacement is correctly sized and oriented for your home and Gold Coast conditions

FAQ – Edwards Solar Hot Water

Q: Why is my Edwards solar hot water only lukewarm?
A: The most common reasons are a failed booster element or thermostat, a tripped breaker, shaded or dirty collectors, or a system that’s simply undersized for your current household. A licensed plumber can test the booster, clean and inspect the solar side, and advise if the system size is still suitable.

Q: My Edwards roof tank is leaking – can it be repaired?
A: Small leaks from fittings, unions or valves can often be repaired. If the leak is from the tank shell or welds, especially on an older unit, replacement is usually the only safe and cost-effective option. Stainless steel is more resistant to corrosion, but it can still fail over time in real-world conditions.

Q: Are Edwards solar hot water systems still made?
A: The Edwards brand is now owned by Rheem Australia, and many original Edwards models are no longer produced under that name. However, there are equivalent Rheem / Solar Edwards systems and spare parts, and existing units can usually be serviced or replaced with compatible modern systems.

Q: How long should an Edwards solar system last?
A: Stainless steel Edwards tanks were marketed as long-life and low-maintenance, and many systems do run for 15–20 years or more. In practice, lifespan depends on water quality, installation, and maintenance. Visible corrosion, repeated leaks or noisy operation are signs it’s time for a professional check.

Q: Can you replace just the Edwards tank and keep the existing solar panels?
A: In many cases, yes — plumbers routinely replace a failed Edwards tank and re-use the existing collector(s) if they’re in good condition, which can save money. We’ll inspect your collectors and pipework and let you know whether a tank-only replacement makes sense.

If it can't be fixed we can supply a new system from as little as $24 a week
