Guide to taps with boiling water: All you should know

In theory, taps with boiling water offer unmatched convenience, delivering instant hot water for cooking and beverages, thereby saving significant time. However, many proponents of taps with boiling water often fail to highlight the problems associated with these systems. Let’s take an unbiased look at them.

How Taps With Boiling Water Work

Boiling water taps, or instant hot water taps, are all about getting boiling water quickly and easily, right from your tap. So how do they function?

  • Instant Hot Water on Tap: Boiling water taps, a.k.a. instant hot water taps, provide boiling water directly from your tap, no waiting needed.
  • Connection to Home Water Supply: They’re connected to your home’s water line, with a small boiler or heating tank under the sink.
  • Consistent Heat: The tank heats water to near-boiling (around 98°C to 100°C), controlled by a thermostat for constant temperature.
  • Insulated for Efficiency: Both the tank and plumbing are insulated to prevent heat loss, maintaining system efficiency.
  • Safety Features: Some of these taps are also equipped with safety features like child-proof handles, cool-to-touch spouts, and automatic shut-off to prevent accidents. Generally, the more expensive taps feature more stringent safety features.
  • Continuous Hot Water Supply: Activating the tap releases hot water from the tank, while cold water refills it for an ongoing supply.
  • Adjustable Temperature Controls: Some models offer temperature settings, perfect for when you don’t need super-hot water.
  • Built-in Filtration System: Many such taps also include filters, improving the water’s taste and quality.

Risks Of Taps With Boiling Water

Boiling water taps are becoming popular in Australian homes for their promise of instant hot water, but this convenience comes with significant risks.

Scalding and Burn Risks

  • The biggest danger is the risk of scalding. Children or elders are most at risk of minor to major injuries. These taps dispense water at near-boiling temperatures, capable of causing severe burns if used improperly.
  • Even though many such taps are equipped with safety features like child-proof handles and insulated spouts, the potential for accidents remains.

Maintenance and Limescale Build-up

  • In places where the water is even remotely on the harder side, taps with boiling water are prone to limescale build-up. This not only affects the tap’s performance but also makes maintenance more intensive and expensive.
  • If these taps aren’t maintained properly, even a small failure in the system can lead to serious injuries.

Complex Installation and Cost Implications

Fitting a boiling water tap isn’t exactly a DIY job. You’ll likely need to bring in a pro for the plumbing and electrical work, which adds to the expense. Also, keep in mind these taps aren’t just a one-time buy; they’ll up your electricity bill since they need a sizeable amount of power to maintain that hot water on demand. In most cases, this is much more than refrigeration system uses because to get ambient water from 20C to 100C is a difference of 80C, conversely, 20C to 4C is only a 16C difference for chilled only systems.

Suitability Concerns for Australian Homes

Considering these risks, it’s obvious that not every Aussie home is cut out for a boiling water tap. Homes with little ones or older family members could find the risk too high for the convenience. Plus, if you’re in an area with hard water, be ready for regular, possibly pricey, upkeep.

Alternative Options to Boiling Water Taps

For times when you need boiling water, traditional methods like using a kettle, stove or coffee machine (most have hot water dispensers) can be more cost-efficient and safer. In scenarios like water disinfection, consider advanced solutions such as filtration systems. As for daily water needs, Soda tap offers innovative products. Although their systems don’t provide a boiling water function, they excel in delivering chilled, sparkling, and ambient water, focusing on functionality, safety, and addressing issues like scale buildup without the risks associated with boiling water taps.

Cost Of Taps With Boiling Water

Let’s talk money. First up, buying a boiling water tap isn’t cheap. You’re not just getting the tap; there’s also the boiler tank and filters to think about, and they’re all more pricey than your usual tap or kettle.

Then, there’s the ongoing cost to keep in mind. These taps need power to keep the water hot, so expect your electric bill to take a hit. If you’re watching your budget, this is something to really consider.

And don’t forget about keeping it in tip-top shape. Regular cleaning, getting rid of limescale, swapping out filters – it’s all part of the deal. Especially if you’re in a hard water area, these maintenance tasks can add up over time.


Wrapping it up, boiling water taps might seem like the ultimate kitchen upgrade, but they’re not without their hitches. Think scalding risks and a hit to your wallet with installation and ongoing costs. Especially for homes with kids or in hard water zones, they might be more hassle than help. Old-school kettles or stoves are more than enough when you need boiling water. For everything else, cool options from Sodatap could be your safer bet. So, give it a good think before you leap into the boiling water tap bandwagon.
