How much does an electric hot water system cost to run?

A 315 L electric storage tank on off-peak tariff typically costs $400–$700 a year for a family of four. Switching to a heat pump on the same usage usually drops that to $150–$250 a year.

Should I replace my electric storage tank with a heat pump?

If your tank is over 8 years old and you have outdoor space, a heat pump is usually the better long-term choice. After the federal STC rebate, the installed price is often only $1,000–$1,500 more than a like-for-like electric tank and you save that back in 2–3 years.

Can you install on off-peak (controlled load)?

Yes. We wire to existing off-peak circuits and can liaise with your electrician to add or change a controlled-load tariff where needed.

Do you service Sydney, the Central Coast and Newcastle?

Yes. Infinity Hot Water covers every suburb across Sydney, the Central Coast and the Newcastle / Lake Macquarie region. Our vans are stocked for same-day work and we respond to urgent jobs within 90 minutes.

Are your plumbers licensed and insured?

Every technician we send is a fully licensed NSW plumber and gasfitter, carries public liability insurance, and is qualified to work on Rheem, Rinnai, Dux, Bosch, AquaMAX, Vulcan, Stiebel Eltron, Sanden, Reclaim Energy and other major brands.

Do you provide a written quote before starting work?

Yes. You receive a fixed, written quote before any work begins — no hidden fees, no surprises. Emergency call-outs are quoted on arrival once we have diagnosed the fault.

Electric hot water Sydney: storage tanks, elements and controlled load

Electric hot water systems Sydney households depend on are still the lowest upfront option, especially on a controlled load tariff. We install and replace Rheem, Dux, AquaMAX and Thermann tanks from 50L to 400L and wire back to your existing off peak circuit wherever possible.

Common electric hot water Sydney faults are burnt out elements, failed thermostats, corroded anodes and leaking tanks. Our licensed hot water plumber Sydney team tests each of these on site and offers same day hot water replacement when a tank is beyond economical repair.

Controlled load and why your tariff matters

Most Sydney electric tanks are wired to a controlled load circuit, heating overnight at a much lower rate per kilowatt hour than general supply. Controlled Load 1 typically heats for six to eight hours overnight and suits 250 litres and above, while Controlled Load 2 heats for a longer window including an afternoon boost and suits smaller tanks.

If your hot water suddenly runs out mid week but the tank is healthy, check the tariff before condemning the unit. A retailer change, a failed off peak contactor at the switchboard, or a household that has grown by two people can all produce the same symptom, and none of them require a new cylinder.

Anodes, elements and getting a full lifespan

The sacrificial anode is the single part that decides whether a tank lasts eight years or eighteen. It corrodes so the steel cylinder does not, and once it is gone the tank begins to rust from the inside. Checking it at year five, and replacing it if consumed, costs a fraction of a new system.

Elements and thermostats are consumables and both are replaceable in under an hour. A tank that leaks from the cylinder itself is not repairable at any price, and any plumber who tells you otherwise is selling you a temporary patch on a component that is already failing.
