learning about tankless water heaters requires first to understand the main basis of heat production in a tank water heater, it is a basic introduction to hot water supply. a good way to understand this is to compare the traditional tank water heater versus tankless water heater. Let's start with tank water heaters

cold water goes into a kettle and heats the entire fluid content. you can only produce water temp at the rate it takes to boil water

 

 

 

 

 

 

 

 

 

 

 

However with a tankless

water heater

the temp return is

almost instant

this is due to the heat exchanger design, water travels through the inlet side of the tankless water heater then gets pumped through the heat exchanger which is getting heated by an open gas flame. similar to the tank heater design. it then comes out of the heat exchanger at a hot temp. where its introduced to your plumbing pipe supply and eventually your faucet or shower. one thing is certain when the water is hot it will remain hot for duration of faucet demand. which is a fancy way to say until you turn off the water. with all that info this means one thing! we have to keep the heat exchanger clean and in optimal condition. how do we clean heat exchanger?

"HOT water will be 

constant and endlessLY

at bath temperature"
