HOT WATER TANK
Hot water tank (also called water heater) are used for storing hot water for space heating or domestic use. High efficient insulated hot water tank can retain and stored heated hot water longer, which would reduce fuel costs. These may have a built-in gas, oil burner system or electric immersion heaters. Some types use an external heat exchanger such as a central heating system or heated water from another energy source. The most typical in the domestic context is a fossil-fuel burner, electric immersion elements or a district heating scheme. It is recommend that your tank service, repair and install by a certified contractor. Many insurance companies will not validate your insurance if your system is over ten years old.
Hot Water Tank Replacement Signs:
- signs of water leaks
- calcium built-up
- pilot burner shutting down constantly
- low hot water pressure
- rusty water marks
- lack of hot water
- tank over ten years (Recommend)
Hot Water Tank Three Most Common Parts:
Pressure & Temperature Relief Valve (T&P Valve)
Pressure and Temperature Relief Valve (T&P Valve):
This safety valve is design to release excess heat and water pressure in order to protect the tank from rupture. These valves are set to open when the water pressure reaches 150 psi, or when the water temperature reaches 210 degrees. In the event of a leaking valve, individuals should have a qualified person inspect and replace valve.
This is install inside the water tank to help control the rate of rust and corrosion on the tank. As a result, the anode rod will corrode to protect the expose melt of the tank. These are generally made from relatively pure active metals, such as magnesium, aluminum, or zinc.
Note: This rod will eventually decay overtime which will leave your hot water tank unprotected. The life expectancy of the anode rode is around 3-7 years. It is generally recommend to replace your anode after 5 years in order to extend the life of your tank.
Gas Control Valve
Gas Control Valve:
- This valve on a hot water tank is design to control the flow of gas to the burner.
- Allows the flame to heat the water inside of the tank while monitoring the water temperature.
- Monitor pilot gas and flame. The valve would sense this flame by receiving a electrical signal from the thermopile or thermocouple, which sits in the pilot flame.
- The valve is also design with multiple temperature settings for individual comfort.
