Fast, honest hot water repairs, replacements and installations across Sydney, 24/7.
Whether it’s a cold shower on a winter morning, a tank weeping onto the laundry floor, or a gas unit that won’t stay lit, at Dial Up Plumbing we diagnose, repair and replace hot water systems every day of the week. Most faults turn out to be a repair rather than a replacement: a heating element, a thermostat, a thermocouple, a relief valve. We carry the common parts on the van, so one visit usually does it.
Dial Up Plumbing have been looking after Sydney homes for more than 25 years, and we’re on call 24 hours a day, 365 days a year, because hot water never fails at a convenient hour. You get a licensed plumber at the door, an upfront price before any work starts, and work completed to Australian Standards (AS3500). Every hot water job is backed by our lifetime workmanship guarantee, so don’t sit through another cold shower, call in the team at Dial Up Plumbing.
The right system comes down to what your property can take, how much hot water your household actually uses, and what you want to spend running it.
Electric hot water is still the most common setup in Sydney homes and the quickest to swap like for like, which makes it the practical choice when you need hot water back today. Gas storage and gas continuous flow suit properties with an existing gas connection, and our licensed gas fitters can connect or relocate the supply if needed. A continuous flow unit gives you hot water that doesn’t run out and no tank sitting there slowly corroding. Solar hot water and heat pump systems cost more to install and considerably less to run, and heat pump upgrades attract support under the NSW Energy Savings Scheme, so it’s worth checking the current position through NSW Government energy programs before you decide.
We repair, service and install all of them, including Rheem, Dux, Rinnai, Bosch, Vulcan, Aquamax and Stiebel Eltron, for houses, apartments and strata properties right across Sydney. Most storage systems give 8 to 12 years, and a check-up every 12 months keeps yours at the top of that range rather than the bottom. If you’re weighing a straight replacement against an upgrade, we’ll tell you honestly which one pays off for your place, and if a like-for-like swap is the right call, that’s what we’ll quote. If your system has failed outright, our 24/7 emergency plumbers can get hot water back on fast.
Get in touch with Dial Up Plumbing by giving us a call, or submitting your details on the contact form. Time is of the essence – we’ll get back to you on the same day with availability, rough costs, and general hot water system guidance.
A hot water specialist will be dispatched to your property to assess the current situation, diagnose the problem, carry out the necessary repairs, or provide recommendations for a new/replacement system. We’ll provide all upfront pricing before any work begins.
Once a plumber has had a chance to assess the current system and problems, we’ll provide honest, unbiased advice on whether to repair or replace your current system. For systems over 8-10 years where the repairs required are significant, it may be more cost-effective to install a new system.
Once the job is finished, we will test temperature, water pressure, and the safety valve to ensure the unit is performing correctly. Where required, we can also produce a certificate of compliance.









Our licensed plumbers and gas fitters can repair all types of systems – whether it’s gas storage, continuous flow, electric, solar, and heat pump. We’ll diagnose the problem, provide clear recommendations and pricing, and get the system fixed and running in no time.


We can advise on, supply, and install a new hot water system for your home – whether it be a new build, a renovation, or a system upgrade. Dial Up can help to size the system correctly for your household needs and fit new pipework and connections to ensure seamless water heating.


Most storage water systems have a serviceable life of 8-12 years – continuous flow systems can be maintained to operate for longer. We generally recommend a check-up every 12 months, with a major service every 5 years to ensure safety valves and components are working efficiently.

Solar and heat pump systems are becoming more popular as more NSW households move towards energy-efficient and solar powered devices under the NSW Energy Savings Scheme. We can set up, install, and maintain your solar hot water system to keep your hot water running seamlessly.
It depends on the type of system, the capacity you need, and whether the install is a straight swap or needs new pipework, gas or electrical work. A like-for-like replacement is the cheapest path, while changing type or relocating the unit costs more. We quote upfront before any work starts, so you have the final figure before we begin, and we’ll say so if a cheaper option would do the job.
Most storage systems give 8 to 12 years. Gas continuous flow units often run longer because there’s no tank to corrode, and solar collectors can outlast the cylinder sitting underneath them. Servicing is what decides it: a system whose anode and relief valve were maintained lands at the top of that range, and a neglected one lands at the bottom.
Under about 8 years with a single failed part, a repair almost always wins. Past 8 to 10 years with a significant repair in front of you, replacement is usually the better spend, because the cylinder is close behind and you’d be paying for the same system twice. A leaking tank is always a replacement, since a corroded cylinder can’t be repaired by anyone.
Heat pumps and solar lead by a clear margin, because they move or collect heat rather than generating it from scratch. Gas sits in the middle, and electric storage is the least efficient by design. Heat pump upgrades attract support under the NSW Energy Savings Scheme, which changes the comparison considerably, so it’s worth checking the current position before you commit.
Often, yes. A like-for-like swap where the type, capacity and location all stay the same is usually a same-day job. It takes longer if the system is being relocated, if you’re changing from one type to another, or if gas or electrical work is needed to suit the new unit. We’ll tell you which one you’re looking at before we start.
As a guide, allow 50 to 70 litres per bedroom per day. That puts a two-bedroom home around 125 to 160 litres and a four-bedroom home around 200 to 250 litres. Continuous flow systems are sized by flow rate rather than tank capacity. We size it on site, because how a household actually uses hot water matters more than the bedroom count.
