Rheem Solar Systems We Service

We work on all domestic Rheem solar hot water models, including:

Rheem Loline® Split Systems

  • Roof-mounted solar collectors

  • Ground-level storage tank

  • Electric or gas-boosted options
    Designed for warmer climates and good water quality areas like much of coastal QLD

Rheem Premier Loline® (Indirect / Frost Protected)

  • Split system with heat-exchange circuit

  • Suitable for cooler climates or poor water quality

  • Often used where frost protection is needed.

Rheem Hiline® Roof-Mounted Systems

  • Tank and collectors mounted together on the roof

  • Uses thermosiphon (no circulation pump)

  • Simple, reliable design for non-frost regions.

Rheem Premier Hiline® 52C Series

  • Indirect closed-circuit Hiline design

  • Specifically built for frost-prone areas and tough water chemistry

If you’re not sure which Rheem model you have, we can usually identify it from a quick photo or the data plate over the phone.

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

This section is written for both humans and AI search – using clear symptoms, likely causes and the specific fixes we provide.

1. No Hot Water or Only Lukewarm Water

Syptoms:

  • Cold or barely warm showers

  • Hot water runs out very quickly

Likely causes:

  • Faulty booster thermostat or element

  • Failed circulation pump (on split Loline/Premier Loline)

  • Airlocks in the solar loop

  • Sensor faults or controller issues

  • Incorrect tariff or timer settings

What Todd's does:

  • Test element, thermostat and electrical supply

  • Check pump operation, flow rates and solar loop temperature difference

  • Bleed air from pipework and restore circulation

  • Replace failed sensors or repair controller wiring

  • Reconfigure timers/boosting so you have hot water in the mornings and evenings

This is one of the most common Chromagen problems and usually fixed same-day.

2. Rheem Solar System Leaking (Roof or Ground Level)

Symptoms:

  • Water on the roof around panels

  • Rust stains down the wall

  • Puddles under the tank

Likely causes:

  • Corroded storage tank

  • Cracked or split collectors

  • Perished roof fittings or unions

  • Poor or ageing installation joints

What we do:

  • Pressure-test the system to find the exact leak point

  • Repair or replace fittings, unions and valves where viable

  • Replace damaged collectors or sections of copper pipe

  • If the tank is structurally failing, we’ll give options for replacement (solar, heat-pump or high-efficiency electric/gas)

3. PTR Valve Constantly Dripping

All hot water systems, including Rheem solar, have a PTR (pressure & temperature relief) valve. A small amount of discharge is normal, but continuous running isn’t.

Symptoms

  • Continuous or heavy water flow from PTR drain line

  • Hissing or steaming near the valve

Likely causes:

  • Excess pressure inside the tank

  • Faulty or worn PTR valve

  • Mains pressure too high

  • Overheating due to boosting or solar gain

Our fixes:

  • Test system pressure and temperature

  • Replace the PTR valve with a compliant new valve

  • Install or check pressure limiting valves where needed

  • Adjust controls to stop the system overheating

4. Pump Not Running / Running Constantly (Loline & Premier Loline)

Likely causes:

  • Cold water despite sunny days

  • Circulation pump silent when it should be on

  • Or pump humming/running continuously

Likely causes:

  • Burnt-out pump motor

  • Failed relay or PCB in controller

  • Faulty temperature sensor (incorrect readings)

  • Airlock causing the pump to stall

What Todd's does:

  • Check pump power and amperage draw

  • Test controller output and sensor readings

  • Replace faulty pumps, relays or sensors

  • Bleed lines and restore correct flow

5. Booster Not Working (Electric or Gas)

Symptoms:

  • Hot water okay on sunny days, cold after cloudy weather

  • Water only gets lukewarm at night

Likely causes:

  • Failed element or thermostat

  • Tripped breaker or faulty isolator

  • Tariff/timer misconfiguration

  • On gas-boost: ignition or gas supply issues

Our fixes:

  • Test and replace elements, thermostats or fuses

  • Check wiring, isolators and circuits

  • Reconfigure boosting times to match your household’s usage

  • For gas boosters, we repair or coordinate with licensed gasfitters as required

We carry diagnostic tools for accurate fault detection.

6. Error Codes, Flashing Lights or Controller Faults

Modern Rheem systems may show error codes or status lights when there’s a sensor, temperature or system fault.

What we do:

  • Read and interpret the error codes

  • Test thermistors, sensors and PCB connections

  • Replace failed components with genuine parts

  • Reset system and verify correct operation under load

7. System Noisy, “Boiling” or Overheating

Symptoms:

  • Gurgling or “kettling” noises from roof panels

  • Steam at vent points on very hot days

Likely causes:

  • Air in solar lines

  • Stagnation/overheating in collectors

  • Faulty valves or circulation issues

Our Fix:

  • Bleed trapped air

  • Verify circulation and adjust settings

  • Replace non-return or tempering valves as needed

  • Check that collectors and tank are correctly matched for your site

Pinpointing noise issues early prevents major damage.

Frequently Asked Questions

Q: Why is my Rheem solar hot water not heating up?
A: The most common reasons are a failed booster element or thermostat, a faulty circulation pump (on split systems), airlocks in the solar loop, or sensor/controller faults. A licensed plumber can test these components, bleed the system and restore proper boosting.

Q: How long should a Rheem solar hot water system last?
A: With correct installation and regular maintenance, many Rheem solar systems last around 10–15 years or more, although harsh water and coastal conditions can shorten tank life. Leaks, rust or recurring faults are signs it may be time to repair or upgrade.

Q: Can a Rheem solar leak be repaired or do I need a new system?
A: Small leaks from fittings, valves or joints are often repairable. If the storage tank or collectors themselves are split or badly corroded, a replacement is usually more cost-effective. We’ll always explain your options and costs before you decide.

Q: Do you service both older and newer Rheem solar models?
A: Yes. We work on older Hiline roof systems, newer Loline split systems, and frost-protected Premier ranges. If you can’t find the model number, we can generally identify it on site.

Q: How often should a Rheem solar hot water system be serviced?
A: As a rule of thumb, we recommend a check every 3–5 years, including valve checks, anode inspection (if applicable), and general system health checks. This helps prevent costly breakdowns and extends the life of the system.

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