The best hot water dispenser with superb filtration

best hot water dispenser



The iconic InSinkErator contour hot water dispenser with filtration system is a product of a company which boasts of vast experience that dates back to as far as 1927.

How it works

It is a point of use water dispenser. The hot water tank is connected to the main water source of your home.

The top part of your sink should have a hole that can receive the faucet of the InSinkErator hot water dispenser system.

Mind you, the thickness of your counter or sink should not be more that 3 inches thick.

Just utilize holes on your existing sink top, provided you have an extra hole. If you don’t have any extra holes on your sink top, then engage a professional plumber to drill the hole on your behalf.

When the holes are drilled, it’s now time to set up the hot water dispenser system.

Insert the hot water dispenser spout through the sink`s hole .When the spout has been inserted, you can now tighten it in place using a large nut from underneath.

The next stage is to mount the hot water tank under the sink

You then need to connect the hot water tank to the water supply pipe using the fittings provided.

Once the tank has been mounted in place and connected to water supply, it is now time to connect the tank the faucet using the plastic tubes provided with the purchase.

When done with the installation, it’s time to connect the hot water tank system to a power outlet.

The incoming water is filtered by the F-1000 S filter before it is fed into the hot water tank. The filtration eliminates all odours, chlorine and other contaminants from your water.

The hot water tank starts working when connected to a power source .If there is no water is the tank; the dry-start protection feature automatically switches off the heating element to protect the system from burnout.

When there is water in the tank, the 750 watt element starts heating until the water reaches the set maximum temperature. The temperatures can be adjusted from 160 degrees Fahrenheit to 210 Fahrenheit using the easy to use controls on the front of the water heating system.

When the water reaches the set max temperature, the standby mode is activated .This ensures that energy is not used unnecessarily .When in standby mode, the heating element uses less that 40 watts. The 40 watts used are just for maintaining the hot water at that set temperature throughout the day.
