Sick of running out of hot water? That’s not a problem with one of these compact, ultra-efficient units that heat water as you need it. Here’s what you require to learn about selecting, installing, and dealing with a tankless water heater.
Think about it: The way most families in this country heat water is ridiculously inefficient. We fill up huge 40- to 50-gallon tank, then put energy into them 24/7, year in and year out, to make sure we have hot water at the ready whenever we desire it.
However often it does not work out that way. If a teen takes a long shower, or a spouse settles in for a tub soak, there can be a long wait for that cleared tank to reheat. Then there are the bothersome worries: Is it filled with energy-robbing sediment? Will it spring a leak? Both are reasonable concerns, as tanks normally stop working in 8 to 12 years.
Tankless Water Heater in North Hollywood Setup: Is It Worth It?
These are the arguments for buying a tankless water heater. It produces hot water just when you need it– and for as long as you need it– saving 27 to half of fuel costs over tank-type heaters. (A common gas-fired tank wastes 40 to 50 percent of the fuel it burns.).
And because there’s no tank to fail, there’s nearly no chance of a devastating leak. What’s more, considering that their introduction in the United States in the 1990s, tankless heaters have become significantly sophisticated, with functions like integrated recirculating pumps (for “immediate” warm water), and wireless connection that tells you through mobile phone precisely when an unit needs maintenance.
Below is our guide to tankless water heaters. In it, we’ll discuss how a tankless water heater works, inform you what you need to know prior to you purchase one– and before the installer arrives– and let you in on the systems’ operating quirks, so there won’t be any surprises if you go tankless.
How Does a Tankless Water Heater in North Hollywood Work?

It all starts when you turn on the hot-water tap (1 ).
A circulation sensor (2) finds water coming into the heater and sends out a signal to the control board to start producing hot water.
In a gas-fired system, the control panel (3) turns on the fan (4 ), which draws in outdoors air, opens the gas valve (5) that lets in the gas, and ignites the burner (6 ).
The heat exchanger (7) catches heat from the flames and transfers it to the water moving through the exchanger’s tubing.
The blending valve (8) moods the superheated water exiting the exchanger.
If the temperature level sensor (9) finds that the water goes beyond or falls short of the wanted setting, the panel will change the gas valve, the mixing valve, and the flow-regulating water valve (10) accordingly.
A sealed vent (11) (or pair of vents) through a roofing or outside wall carries away exhaust gases and conveys combustion air to the burner.
