3. Tankless Water Heater FAQs

On this introduction page we'll start by showing you the basic differences between a tankless and a tank water heater as well as to highlight some of the advantages.

A tankless water heater is high technology.
It's 20% to 50% more efficient than a tank unit.
Tankless Water Heaters. A tankless uses high technology--a microprocessor, sensors and efficient gas burners. It takes in cold water into the unit, flash heats it and sends it directly to your hot water device--bathtub, shower, washing machine or dishwasher. The result: no need to store water in a big 50-gallon tank. This is a huge advantage.

Tank Water Heaters use old technology based on the first
water heaters developed in the 1870s. It looks like a hot water thermos—very inefficient—it uses energy 24 hours a day, seven days a week.

Let's take the cover off and look inside. A tankless water heater consists of four basic parts: gas burner, microprocessor (computer), electrical, and gas inlet.
Tankless Water Heaters Inside View


A tankless water heater heats hot water in 4 basic steps.
Step 1: You turn on a hot water device (shower, tub, etc.).
Tankless water heaters heat water only when you need it. When you turn on the hot water in your house the water begins to flow and your tankless unit has a sensor that detects the water flow to the unit and tells the computer that you want hot water.

Step 2: Sensors talk to the computer (microprocessor).
The start-up process takes about five seconds.  The sensor automatically ignites the gas burner. It also calculates the the precise power output, the desired temperature setting, and the flow rate. Then the water flows across the heat exchanger and is sent to your hot water device. As the water flow changes, a thermostat controls the burner to ensure a constant temperature is maintained.

Step 3: Cold water In. Hot water out.
Unheated water comes into the unit, circulates through the heat exchanger (it takes a few seconds) and exits the unit at the desired temperature. The water is heated rapidly (a few seconds).

Step 4: The tankless water heater shuts off automatically.
When you turn off the hot water the unit automatically shuts off. As soon as the flow sensor detects that water has stopped flowing the microprocessor shuts off the burner. So when hot water is not being demanded, absolutely no energy is being consumed.

A tankless water heater is smaller and saves you money.
Tankless Water Heaters. A tankless water heater is designed to heat water as it flows through the unit. It's about the size of a piece of carry on luggage-- a box about 24” high by 14” wide and 9” deep that can be mounted on an exterior wall of your house, or can be mounted in the interior of your house.  

Outdoor & Indoor Water Heater Unit

A tankless unit size is based on the amount of hot water it produces per minute. Units come in different sizes--some produce 1/2 gallon per minute while others can produce 14 gallons of hot water per minute.

Tank Water Heaters.  A tank water heater size is based on the number of gallons in the storage tank. Here's what a tank water heater looks like--a 50 gallon thermos.

Some issues to consider
There are some practical differences between running a tankless and a tank.
1. House Layout. Some houses have a physical layout that more efficient for tankless than others. Our technician can analyze your layout and give you a clear idea on how effective a tankless can be for your situation.
2. Hot water devices--speed. It may take a few seconds longer to get hot water. They also make it take longer for you to get your hot water, since they don't start heating the water until you turn on the faucet. This
problem can be solved by using a hot water recirculating pump, which in combination with the tankless unit can get your hot water to you at less than half the time it would take running the faucet full blast.
3. Water use may increase. The tankless water heaters also cause an increase in water wastage since you have to let the water run longer to get your hot water. This problem is solved when using a hot water
recirculating system. Water conservation is an important advantage to the hot water recirculating. With it you get both water conservation and
convenience benefits of faster hot water, and, an unlimited amount of hot water.
