Continuous flow hot water service & instantaneous systems
A continuous flow hot water service heats water only when you turn on the tap, so you never run out and you stop paying to keep a tank hot overnight. It is the most popular hot water system replacement in Sydney homes with limited space, and the units mount neatly on an external wall.
We install, service and repair every major continuous hot water service brand, including Rinnai Infinity, Rheem, Bosch, Dux and Vulcan. If your existing unit is throwing fault codes, cycling cold, or struggling in winter when Sydney inlet water drops, our technicians diagnose it on the spot and quote the repair before starting. Same day hot water repairs and replacements are available seven days a week.
Popular hot water repairs in Sydney
- No hot water at all, or hot water that runs out fast
- Leaking tanks, relief valves and tempering valves
- Pilot lights and gas burners that keep going out
- Failed elements, thermostats and anode rods
- Heat pump and solar hot water faults
Hot water systems Sydney: frequently asked questions
How much do hot water systems cost in Sydney?
Most Sydney hot water systems cost between $1,200 and $2,600 supplied and installed for gas or electric storage, $1,800 to $3,200 for continuous flow, and $3,000 to $5,500 for a heat pump before NSW rebates. You get a fixed written quote before any work starts.
How fast can you repair my hot water system?
We run 24/7 emergency hot water repairs across Sydney, the Central Coast and Newcastle with a 90-minute average response. Most repairs are completed on the first visit because our vans carry common valves, elements, thermostats and gas parts.
What is a continuous flow hot water service?
A continuous flow (instantaneous or tankless) hot water service heats water on demand instead of storing it, so it never runs out and there is no standby heat loss. We install and repair every major continuous flow brand including Rinnai Infinity, Rheem, Bosch and Dux.
Do you replace hot water systems the same day?
Yes. If your system cannot be repaired economically we can usually supply and install a replacement the same day, including removal and disposal of the old unit and compliance with NSW tempering valve requirements.
Do you service Rinnai Infinity hot water systems?
Yes. Infinity is Rinnai's continuous flow hot water range, and our technicians service, repair and install every Infinity model along with Rheem, Bosch, Dux, Vulcan and Thermann continuous flow units. We are Infinity Hot Water, an independent Sydney hot water specialist, not the manufacturer.
How much does a hot water system replacement cost in Sydney?
A like-for-like hot water system replacement in Sydney usually runs $1,800 to $2,600 installed for gas or electric storage, $2,200 to $3,400 for continuous flow, and $3,000 to $5,500 for a heat pump before NSW rebates. The quote includes removal of the old unit, tempering valve compliance and your compliance certificate.
