tankless hot water repair

Tankless hot water systems, sometimes called instant water heaters, deliver hot water on demand to a household. Of all water heating systems, tankless systems are the most energy efficient as they aren’t susceptible to standby energy losses like conventional tank-style heaters. Repairs won’t cost you an arm and a leg either, as long as you use qualified hot water plumber.

However, improper maintenance can hurt this efficiency. The best way to ensure you get the most out of your tankless hot water heater is to have your unit regularly serviced. Routine servicing will extend the lifespan of your water heater and prevent defects that can be costly to repair.

What do tankless hot water system repair and servicing entail? How can you ensure that your service and repair efforts are cost-effective and beneficial over the long haul?

Hot Water Systems Sydney offers quality tankless hot water systems repair and service solutions to property owners in Sydney. Below, we’ll be discussing our services and how they can benefit you at length.

Tankless Hot Water Service

A tankless hot water system typically performs incredibly well in terms of longevity. With proper maintenance, your unit can last for up to 20 years.

We recommend servicing your unit at least once per year unless your system is set to high temperatures, in which case you may want to bump it up to twice per year to prevent the build-up of scale.

In a tankless system, water is heated by a heating element called a heat exchanger powered by gas or electricity. As time passes sediment from your water supply can build up in this exchanger causing at the least decreased efficiency—and at the worst system failure.

Given this, routine maintenance of your tankless system is of the utmost importance. When we carry out a tankless water heating system service, we use specialised gear to determine if there are any issues or potential problems. We also give your unit a thorough cleaning and descale the heat exchanger to remove any mineral build-up.

We may also replace consumable or defective components if necessary and offer an estimate of your units remaining functional life. If, unfortunately, your tankless water heater will need to be replaced, we do that too, and we’ll have you up and running again in no time.

Common Tankless Hot Water Heater Repairs

A tankless hot water system that isn’t serviced at regular intervals may experience several common problems, among others, that may include:

– A mineral build-up in the heat exchanger
– System overload if hot water taps are open in two bathrooms at the same time
– An “Air Supply” message display due to problems with combustion air or venting
– A “No Ignition” message display because of gas supply issues.

Preventing these problems comes down to routine maintenance and inspecting the unit’s connections, valves, and other components.

While you may have no problem sorting out minor issues yourself, for everything else, give us a call at Hot Water Systems Sydney. We’ll come whip up a no-obligation quote, get your system back to running at its best, and set-up a plan of attack to keep future maintenance on schedule.
