Tankless water heaters, also known as instantaneous water heaters provide hot water only when needed. So unlike tank storage water heaters, they don’t release hot water from a ready reservoir, but instead they generate warm water with electric coils or high-powered gas burners.
If you want to find out the pros and cons of investing in a tankless water heater, check out our guide below.
Instant Hot Water
They are really good for supplying an endless flow of hot water whenever you need- even better that it’s instant.
Tankless water heaters last about five to ten years longer (approximately 20 years) than a tank storage heater. It’s a good investment if you want to avoid a hefty replacement fee.
One of the most distinct advantages to tankless water heaters are that, they eliminate the unnecessary cost of keeping forty to fifty gallons of water hot in a storage tank. Resulting in a lot less energy waste.
Even if your main priority isn’t necessarily on saving money or energy, with tankless water heaters you’ll be saving a ton of space in comparison to the traditional storage heaters. You won’t have the inconvenience of bulky storage tanks, that’s for sure.
You’d also have the option of installing them either indoors or outdoors with anti-freeze. Smaller units can even be installed in closets or under cabinets.
Parts are replaceable. For example, if a heat exchanger fails (even after the warranty period), you have the option of purchasing a new heat exchanger and thus replacing the defective one. In contrast, tank type water heaters do not allow for part replacements, which means you’d have to purchase a whole new system.
Mitigates Flood Risk
Tankless systems eliminate the risk of flooding in case of a ruptured tank- something that is prevalent in more traditional water heaters.
In contrast, storage tanks are known to burst, especially when reaching its expiry. This isn’t just a nuisance but it can also be dangerous. Check out the video below for a visual example of a hot water tank burst disaster!

You may need to add a larger natural gas line to ensure that the unit is supplied with enough fuel. However, this is not always the case. A technician would be able to advise further on this after evaluation.
Pricey Initial Cost
Although cheaper in the long-term, tankless water heaters can cost up to three times as much as storage tanks. Necessary venting and piping add to the installation costs.
Smaller units don’t always produce enough water to provide for the whole household. So, either choose to run the dishwasher or a hot shower as the water heater will only serve one faucet at any one time.
Larger units won’t have this problem; they are able to handle the demands of the whole household.
Unless the system has a modulating temperature control, you may find inconsistencies with temperature with various flow rates.
You can combat this by investing in a modulated tankless water heater that allows change in heat output depending on the flow rate of water running through the unit.
- Based on the points above, the advantages outweigh the disadvantages.
- This is not a DIY task, unless you’ve done something similar at pro level before.
- When it comes to pricing make sure to get an estimate before you make a decision on going tankless.
- Initial installation is pricey, but a lot more cost-effective in the long run.
