How long does a hot water system last?

Most hot water systems last about 8 to 10 years. Checking the anode and the pressure relief valve, and fixing small faults early, helps a system last longer.

Which hot water system is cheapest to run?

Heat pumps and solar usually cost the least to run. Electric storage is the cheapest to buy but generally one of the more expensive to run, and gas storage is among the more expensive too.

Should I repair or replace my hot water system?

Repair it when a part has failed on a system that is not too old: a tempering valve, an element, a thermostat or a relief valve. Replace it when the tank itself leaks, or when it is near the end of its life and the repair is costly.

How much does a new hot water system cost in Sydney?

About $1,000 to $2,900 for electric, $2,100 to $3,300 for gas storage, $1,700 to $3,300 for continuous flow, $3,800 to $6,650 for a heat pump and $4,500 to $8,000 for solar, installed with GST, before discounts.

Can you replace my hot water system the same day?

Often, yes, for a like-for-like replacement when the size is in stock. Call us early and we tell you when a plumber can be there.

Which brands do you install and repair?

Every hot water brand Reece sells, including Rheem, Thermann, Everhot, Rinnai, Bosch, Aquamax, Vulcan, Stiebel Eltron and Haier, plus Billi boiling and chilled water units.

Do you do commercial hot water?

Yes. Storage and continuous flow systems for heavier demand, including high-output continuous flow units of 32 to 50 litres per minute.

Is there a call-out fee?

No call-out fee Monday to Friday, 7:00am to 5:00pm. Outside those hours an emergency call-out fee of $199 to $399 applies.

REPAIR OR REPLACE?

Repair or replace your hot water system?

Repair it when one part has failed on a system that is not too old: a tempering valve, an element, a thermostat, a relief valve or a gas ignition fault. Hot water repairs.

Replace it when the tank itself is leaking, because a leaking tank cannot be repaired, or when the system is near the end of its life and the repair is costly. Most hot water systems last about 8 to 10 years (Solar Victoria). Hot water replacement.

Either way, you get a fixed price before any work starts, and the choice is yours.

COMMERCIAL

Commercial hot water

Cafes, gyms, strata buildings, schools and workplaces need hot water for heavier demand. We install and service commercial storage systems and high-output continuous flow units of 32 to 50 litres per minute, and systems configured for bigger loads.

We work to your building’s schedule, with work orders and compliance paperwork. Commercial plumbing.

BOILING AND CHILLED WATER

Boiling and chilled water taps

We supply and install Billi boiling and chilled water units: filtered boiling and chilled water from one tap, with the unit hidden in the cupboard below. They are sized by the number of people served, from about 10 to 60, so they suit kitchens, offices and staff rooms.

They filter the water as well. See our water filters too.

THE RULES IN NSW

Temperature rules every installation must meet

Storage hot water must be heated to at least 60°C at least once every 7 days, to stop bacteria such as Legionella growing (YourHome).

Water at showers, baths, basins and bidets must be no hotter than 50°C. In NSW a tempering valve or another approved device is required on every new installation and every replacement, including a like-for-like swap (Building Commission NSW). That is why a proper replacement quote includes one, and why faulty tempering valves are among the most common hot water faults in our job records.

FROM OUR JOB RECORDS
