What Does A High Limit Switch Do On A Pool Heater
The high limit switch on a Hayward pool heater is a safety device that is wired in series with the gas valve and the thermostat. If the water temperature going into the pool heater exceeds the maximum set, the gas valve will close, shutting off gas to the burners.
Unusual high-limit operations are a result of problems with the flow of water. Reduced water flow may be caused by
1. Excessive water flow through the external bypass
2. Dirty filters
3. Limescale accumulation in the heat exchanger.
Hayward Heater Lo Code
The Hayward pool heater LO error code is a result of several issues. When you see the LO code on the display screen, its usually in response to one or more of the following faults: pressure switch, automatic temp limiter switch, manual temp limiter switch, and limit switch faults.
Pressure Switch Fault
There are multiple ways to diagnose the pressure switch fault. Start by verifying that the pump is running. If its not, please turn it on. If this doesnt work, proceed to check switch wiring and connections. In particular, look for kink or rodent damages. Youll also want to check terminals for breakage or corrosion.
You can also diagnose the pressure switch fault by measuring switch continuity. Start by removing the wires, then measure the OHMS with the pool pump on. If its closed, the switch is okay. If its open, reconnect the wires and proceed.
Another way to diagnose the pressure switch fault is by checking the water flow. First, ensure the filter and pool pump baskets are clean and no blockage in the impeller. If you have a dirty filter and pool pump baskets, youll need to clean them. Also, unblock the impeller if theres a blockage.
Adjusting the pressure switch can also work when diagnosing the pressure switch fault. So, turn the adjustment screw 1 on clockwise to see if the LO error code disappears. Lastly, the fault could be a result of a defective pressure switch. In this case, replacing it is the best solution.

Incorrect Position Of Bypass Valves
Mainly a bypass valve is used in a pool heater to control the water circulation. It controls the direction of water flow as well. Sometimes, incorrect installation of these valves leads to the water flow restrictions issue.
Because of improper water flowing, the water temperature gets too high, and the heater unit becomes overheated. So, to ensure a fluent heater operation and to get rid of any type of error code, it is needed to the accurate adjustment of the valves.
Environmental And Efficiency Aspects

The efficiency of any system depends on the definition of the boundaries of the system. For an electrical energy customer the efficiency of electric space heating is 100% because all purchased energy is converted to heat. However, if a power plant supplying electricity is included, the overall efficiency drops drastically. For example, a fossil-fuel power station only delivers 3-5 units of electrical energy for every 10 units of fuel energy released. Even though the electric heater is 100% efficient, the amount of fuel needed to produce the heat is more than if the fuel were burned in a furnace or boiler at the building being heated. If the same fuel could be used for space heating by a consumer, it would be more efficient overall to burn the fuel at the end user’s building. On the other hand, replacing electric heating with fossil fuel burning heaters, isn’t necessary good as it removes the ability to have renewable electric heating, this can be achieved by sourcing the electricity from a renewable source.
Variations between countries generating electrical power affect concerns about efficiency and the environment. In 2015 France generated only 6% of its electricity from fossil fuels, while Australia sourced over 86% of its electricity from fossil fuels. The cleanliness and efficiency of electricity are dependent on the source.
