Having no hot water can mean one of many problems, with also being determined by the type of hot water system. Depending on if it is electric, gas or solar hot water system will mean certain actions will need to take place. Either waiting for the hot water to re-heat, upgrading the size of the hot water tank or identifying the issues are some methods which can help restore hot water.
Gas Hot Water System General Repairs
Here are the most common issues with gas hot water systems and how to simply fix them.
When the pilot light has turned off often the flame will not be present as a result. Therefore, relighting will help but many newer models of gas heaters may not have a pilot light. Instead, they might have a glow plug or a spark igniter which means reading the instructions/ owners manual is the safest path to take. However, if the gas system does have a pilot light here is what to do to safely relight it:
- Turn off the regulator and wait around five minutes for the gas to completely disperse
- After this, turn the regulator to the “pilot” option
- If a self-ignite feature is present, for about a minute push down the ignition button then turn the regulator to the “on” position
- When lighting the pilot is needed make sure to use a long lighter to direct the flame towards the pilot burner
If it still does not ignite the issue may be with the inlet valve being closed. As a result, turn the handle parallel to the gas line, and then try to reignite the pilot again. Also, if it still will not work a defected thermocouple may be the issue. Calling the gas utility company or a qualified plumber is the best way to handle the situation.
No Gas Supply
If hot water is not working then checking to see if gas is going into the heater system is possible. The gas supply might have been interrupted or turned off which would have not allowed the system to receive the natural gas. These simple steps with turning on the gas can help:
- Have the gas control knob be turned to “pilot”
- Where the burner and pilot light are located remove the cover to see if a flame is lit inside
When the burner does not work properly these easy steps can help:
- Make sure the burner is off then have the thermostat set to 120 degrees
- Open a tap and turn it to the hot water section
- Watch the burner to see if it ignites, if not, then keep the tap on and turn up the thermostat
- If it ignites replace the cover to then resent the thermostat to its original temperature
Electric Hot Water System General Repairs
With electric powered hot water heaters, the more common problems and how to resolve them are the following.
High-Temperature Cutoff Switch
This system being tripped may be why no hot water is available. Therefore, resetting the switch can help and is easy to do – open the panel and press the button. Hearing a click should reset the switch and the powered should flow back to the water heater. If not, the high-temperature cutoff might be broken/ defected and may need replacement.
Electric hot water systems generally have a lifespan of 10 years. As a result, replacing the old one with a new one might be the only option to take if it is really old.
If a switch in the hot water has been turned off then ensure it is switched back to on. Similarly, with the circuit breaker box, if a switch is tripped then resolving it is important:
- A tripped breaker will be “in-line” with the other switches rather than flipped “off”
- Flip the switch to the “off” point then reverse this by turning it back “on”
- Calling an electrician after the breaker has been reset and still does not work is the needed step to take
Solar Powered Hot Water System General Repairs
Solar-powered hot water heaters may experience many problems, here are the more common and how to solve them.
Circulation Pump Issues
A faulty circulating pump may run constantly or not at all. The pump’s controller may be the issue resulting in the system malfunctioning. When the controller is on however the system will not run then the pump’s impeller might be blocked, therefore clean it. Additionally, when the pump runs periodically at night time the valve might need replacing.
A leaking temperature and pressure relief valve will need replacing as the only option. Leaking may also be caused by burst pipes, a pipe fitting issue or from broken seat deteriorates where a licensed plumber is needed. These issues will not cause the system to work properly, as a result, the solar panel system will not easily create hot water.
Other Issues Stopping Hot Water
If the orientation of the solar panel is facing trees/ shade this might limit the amount of power it receives. As a result, simply move the solar panel to face more sun. Moreover, frozen solar panels in winter can cause the system to malfunction, therefore, have slop on the collector so the output end is increased. Also, if the system losses heat, insulation may be the dilemma, as a result, have proper insulation to the storage tanks, pipes and all the joints.
