Debunking Myths About Tankless Water Heaters

When you turn on the tap, the water still needs to travel through the pipes to reach your faucet. This journey takes time, so the idea of immediate hot water as soon as you twist the knob is a misconception. What you do get, however, is a continuous supply of hot water without the fear of a tank running out of hot water.

Myth 2: Unlimited Supply of Hot water

Another mistaken belief is that tankless water heaters supply an unlimited amount of hot water. It’s true that they can deliver hot water continuously, but their output is limited by their flow rate capacity.

This means if you have multiple hot water demands simultaneously – like a shower, washing machine, and dishwasher running at the same time – the heater might struggle to keep up, potentially resulting in a drop in water temperature or flow.

This is why understanding your household’s peak hot water usage is crucial in selecting a unit with the appropriate capacity.

Myth 3: Tankless Water Heaters are Maintenance Free

Some homeowners believe that once installed, tankless water heaters require no maintenance. This is far from the truth. Regular maintenance is critical to ensure the longevity and efficiency of your unit.

Maintenance typically involves periodic descaling and flushing to remove mineral buildup, especially in areas with hard water. Neglecting maintenance can lead to reduced efficiency and potential damage to the system, ultimately shortening its lifespan.

Myth 4: There’s No Hot Water During Power Outages

The belief that tankless water heaters are useless during power outages is not entirely accurate. While electric models indeed rely on power to operate, gas-powered tankless heaters can still function if they have battery backup for their ignition systems. Therefore, with the right setup, you can still have hot water even when the electricity is out.
