Lots of tankless myths are being spread by people unfamiliar with this technology. But when you strip away these misconceptions, going tankless means saving space, better efficiency, greater longevity, and most importantly, never running out of hot water.
Tankless doesn’t work with cold inlet temperatures.
This is simply not true. With around 100,000 tankless water heaters sold per year in Canada, our water heaters handle cold groundwater easily. The Tankless Truth™ is our water heaters will deliver 19 liters (5 gallons) per minute with 4°C (40°F) groundwater, equal to running three showers simultaneously.
Venting is too expensive on tankless water heaters.
We offer affordable concentric venting, including 2" by 4" diameter for condensing. Concentric vents are beneficial because they require just one penetration through a nearby roof or wall. Additionally, our condensing tankless water heaters can use approved 2" PVC for vent runs up to 65' and in some cases can use room air for intake. The Tankless Truth is we’ve made venting affordable.
Tankless is more expensive to maintain than tanks.
It doesn’t matter if you have a tank or tankless water heater, your water heater must be maintained. In fact, scale will build up to a foot or thicker inside a tank in just a decade. Tank and tankless manufactures both recommend regular flushing. This is a simple process that can be handled by the homeowner, or their trusted plumber. The Tankless Truth is that tankless water heaters are not more expensive to maintain than a tank.
Tankless water heaters don’t respond quickly to high demand.
The speed of hot water coming to your faucet isn’t determined by whether you have a tank or a tankless water heater. Instead it is determined by the distance between your water heater and your fixture. Thankfully, we have a solution for that. The Tankless Truth is we offer tankless water heaters with built-in circulation pumps that deliver hot water to your fixtures quickly and efficiently.
Tankless means upgrading your gas line.
When going from a tank to tankless, there is a myth that says you always need to upgrade the gas supply line. This isn’t always the case. Rinnai condensing tankless water heaters’ zero governor gas valve, switching venturi, and turbo fan work together to pull in the right mixture of gas and air to produce an energy efficient combustion. This allows the tankless water heater to self-compensate for any fluctuations in gas or air supply. The Tankless Truth is, in many cases, you don’t always need to upgrade your gas supply line when going tankless.
Tankless is a new tech that is unproven.
Rinnai has been selling tankless water heaters in North America since the 1990's. But, for decades prior, they have been selling tankless in Japan and other parts of the world. Since being introduced to Canada, tankless has seen double-digit growth. The Tankless Truth is that our tankless water heaters last up to two decades while many tanks are getting replaced in 8-12 years.
