Tankless Hot water heaters are highly in demand among people for daily use.This device saves water, energy and definitely electricity bills. The technology enables it to heat up water as it flows down the pipe. No storage is required for heating the water.
As the water flows regularly across the pipes, it tends to form a layer of copper deposit on the pipes. This deposit eventually reduces the efficiency to get well-heated water in short time. Considering this issue the manual guides of tankless water heater suggests a half yearly flushing cleaning of the device. The flush cleaning process ensures all the core deposits are removed to increase the functional ability of the device.
Equipment That You Require For Flush Cleaning:
When you plan for a flush clean up for your tankless water heater, you will require the below list of equipment to work smoothly-
- Electric Tester with non-contact facility
- A pair of hoses of about 6 feet length, typically used in gardens
- A wrench that is adjustable
- A bucket with capacity of around 5 gallons
- A pump for flushing vinegar
- 5 gallons of vinegar solution
All this equipment together function to get rid all deposit of copper, calcium and other minerals forming on the heater due to constant usage. The tankless heater has a mechanism on it to indicate when the device is in need to flush cleaning. A complete cleaning process by flushing takes about an hour’s time to happen.
Steps to Follow for Flushing out a Tankless Water Heater:
- Turn off any source of power in the water heater. The circuit of electricity, typically located at the broken panel, is to be turned off.
- Get access to the wiring of the water heater unit by removing the cover plate on top of the water heater. You need to use your screwdriver to get it done. Get the wiring tested with the non-contact Electric Tester by touching the tip with the wiring. Ensure there is no current in the line. If there ispower, then you need to turn it off.
- The valve that supplies the water heater with cool water is to be closed. The valves supplying hot water to the house is then to be closed.
- Then one of the ends of the garden hose is to be connected to the pump outlet points. The other end is then connected to thevalve of cold water isolation in the tank. Similarly,the other hose is connected to the hot water supplying valve. Tighten both the hoses with the help of the wrench.
- This pump along with one end open hoseis then placed inside the bucket of 5 gallons. The bucket is then filled up pouring the 5 gallons’ white vinegar.
- Both the valves for cold and hot water supply are then opened, and the pump in the bucket is started to drive vinegar inside the heater.
- This process of vinegar circulation should continue for around 45 minutes before turning the pump off. Once thepumpis turned off the vinegardrains back to the bucket through the open hose. The cold valve is to close post this.
- Clear off the vinegar from the bucket and again place the hose with open end inside the bucket. The cold water valve is then turned on so that the cold water flows down to the bucket. This a process of cleaning vinegar left over for 5 minutes. Once done both the garden hoses are disconnected.
- The final step involves rinsing the screen to avoid any sediment.
