Whether you have installed an outdoor or indoor heating system, you have to get familiar with water heater winterising. While indoor tankless water heater is vulnerable to any influence, the outdoor model is most likely affected by freezing winter temperatures. This makes the installation of a device in the proper location with the efficient venting very important. Items connected to tankless water heating systems are loaded with freeze prevention system, giving water heater protection throughout the winter season. The heating unit automatically turns on regardless of the operation’s position, whether off or on.
Necessary tips in winterising your water heating system:
- You should keep away from facing your vent pipes into the direction of the wind to lower the temperature. This approach is applicable to both dual-vent system and concentric system.
- Never install condensate drain tubing in an area where it is exposed to freezing state. Instead, it should be set-up in the wall.
- Components found inside your tankless water heaters may freeze because of the negative draft into your venting. Remember that negative draft may occur once the furnace or any other gas-powered device gets air supply through the heating system vent pipe, allowing the air to enter and freeze the water into the system’s warmth exchanger.
- The backdraft reducer is another solution for this issue as it closes its internal flapper and limits the backdraft.
- Open the warm water tap and keep some warm water running to protect your unit from extremely cold weather. This requires you to turn off the power and then close its gas supply valve to protect the heater and piping system.
- Disconnect the outlet and inlet water pipes of the water pressure and place a bucket right below then collect water.
- Pressurize your system when the valves inside and outside your house are already opened. There is still a broken pipe or an open valve when the pressure will not build up. Make use of the air compressor so that the remaining or outstanding water will be blown away. Make sure that you cool off the water for a while before draining so it will come out quickly.
- Place a cover for the entire vent termination on intake and exhaust to prevent leave or debris from entering your venting system.
- Check your faucets. Drain the draw-off that is connected to the garden hose. Open up the farthest outside your sillcock originating from the compressor. Close the valve and move on to your inside faucets when you notice that air is the only element that came out. Check each of the faucets in your house and open them until only air comes out.
The water heating system should be drained throughout the winter period. The heater might be severely damaged if you will not take the necessary precautions. Adhere to the tips provided above to avoid this predicament, help save your heating unit, and protect it from possible disruption caused by the cold weather.
