How does tankless water heater works

Plentiful and reliable hot water is essential for civilized life and tankless water heaters are the most Canadian household scene now.

While the name tankless does tell part of the story upfront, there’s more that you need to understand when you’re deciding whether a tankless water heater is right for you.

Lets  give you a tour of one of the most impressive tankless water heaters, the most Canadian homes have tank style water heaters now.

These haven’t changed much since indoor plumbing became a regular part of Canadian home construction more than 75 years ago.

An energy source typically electricity natural gas or propane warms the water stored in the tank until a thermostat shuts off the source of energy at a preset temperature level  .

Now as that tank cools off the thermostat turns on the source of energy again, warming up the water bringing it up to temperature.

Even if no hot water has been used from the taps at all the energy wasted making up for the heat loss from tanks tile heaters is called standby energy losses and this is the main

reason why tankless water heaters are more efficient than tanks.

From the name tankless water heaters have no tank that’s why they’re so small instead they heat the water instantly as  it’s demanded as soon as a hot water tap

is turned on anywhere in your home.

Internal sensors inside the heater detect the flow and ignite the propane or natural gas that heats the water for the second or two, that it’s flowing through the unit.

The moment you shut off a hot water tap anywhere in your house the flame and the heater stops.

The fact is that tankless units only heat water as it’s needed is why this technology is sometimes called on-demand water heaters.

Now besides a complete freedom from standby energy losses and a continuous supply of hot water as long as you want .

These are advantages of tankless technology

Where a typical 60 gallon water heater might take up 72 cubic feet of volume Navian model we are dealing with takes up just two cubic feet of space and yet it

puts out more than 300 percent more heat than a typical natural gas tank heater.

Now selected and installed correctly this model can deliver enough hot water for two showers operating continuously even if the incoming water temperature is a frigid 50 degrees

Fahrenheit or 10 degrees Celsius.

Tankless water heaters do cost more than tank style equivalents and this is one reason why tankless technology is not for everyone, tankless water heaters are definitely

not bottom drawer technology.

Another issue you need to know about is water chemistry, now in cases with particularly hard water or unusual pH levels it’s going to be a problem .

Sometimes for some tankless units it’s not typical but before you make any final buying decisions have your dealer check out your water chemistry first saving energy and saving
