Solar hot water brands we assess

We can assess existing solar hot water systems from brands including:

  • Rheem
  • Rinnai
  • Solahart
  • Thermann

The work available depends on the model, the system’s condition and the availability of suitable replacement parts. Not sure which system you have? A photo of the tank, the collectors and the identification label is a helpful starting point. Send it through the quote form.

Solar hot water repairs

A problem with your solar hot water doesn’t always mean the whole unit needs replacing. A leaking connection, a defective valve or an issue with the circulation or boosting equipment may be repairable. Craig assesses the symptoms, checks the accessible components and explains what he finds before recommending further work.

Common reasons to book an inspection:

  • No hot water, or water that is only lukewarm.
  • Hot water running out sooner than usual.
  • Water leaking from the tank, collectors or connecting pipework.
  • Persistent discharge from a relief valve.
  • An unusual change in system noise.
  • A booster that doesn’t appear to be working.
  • Visible corrosion or deteriorated pipe insulation.
  • A noticeable change in hot water performance.

Faults, system types and boosters

  • No hot water or inconsistent temperature Solar performance depends on sunlight, household demand, stored water and the booster. A sudden loss of hot water can also point to a fault in the plumbing components, circulation equipment, controls or the gas or electric booster. We investigate, and arrange a licensed electrician where electrical testing or repairs are needed.
  • Leaks A leak may come from a pipe connection, valve, collector or the storage tank. Finding the source is the first step. We assess the accessible solar plumbing and explain whether a part can be repaired or needs replacing. Some relief valve discharge is normal during heating; persistent or excessive discharge should be checked.
  • Roof-mounted systems Close-coupled or thermosiphon systems have the storage tank on the roof beside the collectors. Craig looks at the tank, collectors, connections and access. Roof work and tank removal need suitable access and planning, and if an ageing unit needs replacing he’ll explain the practical options for your property.
  • Split systems Collectors on the roof and the tank at ground level, with a circulation pump and controls moving heat between them. A circulation or control fault can cut solar heating even when the tank and collectors look fine, so the system is assessed as a whole. Ground-level tanks can also open up different replacement options.
  • Gas and electric boosters Most solar systems use a gas or electric booster when the sun can’t keep up. If the water stays cold in cloudy weather or busy periods, the booster may need checking. We look after the plumbing and gas side and coordinate electrical work where required.
  • Frost protection Frost protection matters when choosing solar hot water here, and the methods vary between models. Some systems rely on power for part of their frost protection, so follow the manufacturer’s instructions when running or isolating them. Craig considers your location and the manufacturer’s installation requirements when discussing a replacement.

Replacing a solar system, or putting in a new one

If the tank has failed, the collectors are damaged or suitable parts are unavailable, replacing the system may make more sense than more repairs. We help you weigh up:

  • The age and condition of the existing system.
  • The proposed repair cost.
  • Availability of compatible parts.
  • Your household’s hot water demand.
  • Roof and ground-level access.
  • Available gas and electrical supplies.
  • What a suitable replacement system needs.

For a brand new installation, choosing the right system is more than picking a tank size. Collector placement, roof suitability, shading, pipework routes, household demand and boosting all need thought. Piper Plumbing & Gas coordinates the plumbing installation and any supporting trades, and explains the proposed work, access requirements and what’s included in your quote.

Considering a different hot water system?

Replacing an older solar unit is a good time to review which system suits your household. Depending on the property, alternatives include:

  • A heat pump hot water system.
  • An electric storage hot water system.
  • A smart electric hot water system with scheduled heating to suit your solar panels and battery.
  • A gas continuous-flow hot water system.

Smart controls and compatibility vary between models, and running costs depend on your hot water use, energy tariffs and solar generation. Craig can talk through the installation requirements and help you choose an option that suits your household, panels and battery.

Smart electric with solar and batteries

More control over when water heats

With rooftop solar, a compatible smart electric system can heat during solar production hours, which may help you use more of your own electricity. The setup needs to consider your hot water demand, other daytime power use and how your battery is managed.

Depending on the equipment, control may come from built-in scheduling or compatible external controls. A timer alone doesn’t necessarily track surplus solar, so choosing the right controls matters. Craig can coordinate with your electrician to work out a suitable arrangement.

Solar hot water maintenance

Follow the manufacturer’s schedule

Maintenance varies by brand and model. Following the manufacturer’s service schedule helps pick up wear and operating problems early.

Depending on the system, that may mean inspecting valves, connections, insulation, the storage tank and circulation equipment, with other parts at the intervals the manufacturer sets. We help establish the plumbing maintenance your system needs and coordinate specialist work where required.

What affects repair or replacement costs?

It depends on the fault, the system design and the work required.

  • The brand and model.
  • Replacement parts and their availability.
  • The condition of the tank and collectors.
  • Roof height and access.
  • Equipment needed for removal or installation.
  • Changes to existing pipework and valves.
  • Gas or electrical work.
  • Removal and disposal of the old equipment.

We explain the proposed scope and pricing before going ahead. If further investigation turns up more work, we talk it through with you first.

Solar hot water questions

Do you repair solar hot water systems?

Yes. A leaking connection, a defective valve or an issue with the circulation or boosting equipment may be repairable. Craig assesses the symptoms, checks the accessible components and explains the findings before recommending further work.

Which solar hot water brands do you work on?

We can assess existing solar hot water systems from brands including Rheem, Rinnai, Solahart and Thermann. The work available depends on the model, the system’s condition and the availability of suitable replacement parts.

My relief valve keeps dripping. Is that normal?

Some relief valve discharge can occur during normal heating. Persistent or excessive discharge warrants investigation, rather than assuming the valve itself is the only cause.

Why is my solar hot water cold on cloudy days?

Solar systems commonly use a gas or electric booster to top up the solar heating. If your water stays cold during cloudy weather or periods of higher use, the booster may need assessment. We arrange a licensed electrician where electrical testing or repairs are required.

Should I repair or replace my solar hot water system?

If the tank has failed, the collectors are damaged or suitable parts are unavailable, replacing the system may be more practical. Craig looks at the age and condition of the system, the repair cost, parts availability and how your household uses hot water.

Can a smart electric hot water system work with my solar panels and battery?

A compatible smart electric system can schedule heating during solar production hours, which may help you use more of your own electricity. A timer alone does not necessarily track surplus solar generation, so Craig can coordinate with your electrician to assess a suitable arrangement.

Do you look after solar hot water for businesses and wineries?

Yes. Craig provides solar hot water repairs, replacements and new installations for homes, businesses and wineries across the Barossa Valley, Gawler and surrounding areas.
