Instant Heat Water Heaters

Instant Flow Water Heater

Instant Heat tankless water heaters can supply you with hot water almost instantaneously! Depending on where your water heater is located in your home, the hot water may take a while to get to the sink, shower or bathtub. Sometimes it may seem you're waiting for an eternity! If only there was a product that delivered hot water on demand. Well, now there is!

Let It Flow

An Instant Flow Water Heater heats the water as it flows through the unit. The electric heater provides heat to the tubes within the unit. These tubes are filled with water and as the water flows through, it becomes heated. This provides you with hot water in an instant.

The Hidden Success

The water heater is compact and installs under your sink. The water connection is cut in between the supply line and the sink connection. This works out great in garages or tool sheds where you wouldn't normally have hot water. Image how nice it would be to have hot water to wash your hands out there! 

How It Works

Once the water lines are connected, the device just needs to be plugged into a 125-volt outlet.

When the water faucet is turned on and water begins to flow, the flow switch in the unit turns the electric elements on. This heats the water as it flows through. The outcome is instantaneous hot water.

In order to power the heater, you'll need to install a ground fault circuit interrupter outlet. This unit requires a 20-amp circuit in order to power it. 

Limited Usage

Remember, this is only a single-area water heater. Don't confuse this with a whole house tankless water heater. This is designed to heat the water at one sink in your home. If you need more, go with the tankless unit.

Other Water Heaters and Their Problems

Most homes are equipped with gas or electric water heaters. Electric water heaters use either 120- or 240-volt power to energize heating elements that protrude into the water and heat the water. These elements are subjected to water that encompasses them. Every electric water heater has either one or two heater elements that are mounted in the side of the water heater tank. Depending on the size of the water heater and the recovery time, the wattage of these heating elements may differ from one water heater to the next. 

A brand new water heater will work flawlessly for many years, but after time, there are some common problems that will arise. One is that sediment can form on the bottom half of the tank over time and cover the lower heating element. This dramatically decreases the efficiency of heating the water. Think of it as insulating the heater from the water. At this stage of the water heater's life, it is time to replace the water heater, that is if you cannot drain the sediment from the tank via the drain located at the bottom of the tank.

In my personal experience, once the sediment is covering the lower element, it's already too late to save the water heater. In fact, good luck getting water and sediment out of that drain.

A common problem with electric water heater failure is that the elements burn out. But how do you check to see if indeed this is the problem? Well to determine if it has failed, you can go to your nearest faucet and turn on the hot water. If the water is only warm but never gets hot, it is likely that the top heating element is defective. However, if the water starts out hot and quickly gets cold, the bottom element has likely bit the dust.
