If you have an oil hot water heater as your primary hot water systems, it is important to understand that you will need to perform maintenance on the unit on occasion. This maintenance will ensure that the appliance is operating at an optimal level and that its total life is extended. Here, I will provide you with the steps that are necessary to appropriately flush sediments from your oil hot water heater.
1. The first step to removing the sediments from your oil hot water heater is to make certain that the thermostat on the device is placed to the position of “Pilot”. If your unit has an “Off” position, this is appropriate.
2. Now, you must locate the valve at the bottom of the oil hot water heater that is designated as a drain unit. You will want to attach a hose to this drain. Then, take the open end of the hose and run it outdoors so that the water may drain in an area that will not cause damage.
3. Does your oil hot water heater have what is referred to as a “recirculation” pumping unit? If so, it is essential that you turn this completely off.
4. On the heater, you will find a valve that is used to provide the home with cold water. This, too, must be turned completely off.
5. Now, go to the lowest point in your home and turn on the faucet that hot water is emitted from. Once this is done, go to the highest point of the home where there is a faucet and turn on the hot water side. Do not become concerned if no water is emitted from the faucet. As a matter of fact, if any is released, you will need to double check your oil hot water heater to ensure that it is completely turned off.
7. Now, it is time to put the drain valve in the open position. When you do this, hot water that has been stored in the holding tank will begin to flow into and out of the hose that you originally placed on the oil hot water heater. Be certain that there are no people or pets near the end of the hose where the water will be released as it will be very hot and could result in injuries.
By following these steps, you can remove any type of sediment accumulation in your oil hot water heater. For further instructions, be certain to read the instruction pamphlet that came with the unit from the manufacturer or get a professional which I do recommend, for my own work I use a gas plumber in Townsville. Once the tank has been drained, remember to refill the oil hot water heater tank with clean water.
