What is the “clicking” or “sparking” sound I hear, but the heater does not ignite?
- The “clicking,” indicates that the ignitor is sparking and the heater is trying to fire, but the gas and the “spark" are not reaching each other. If the heater has recently been installed, the first thing that must be checked is the gas pressure. Low gas pressure may create a lean gas to air mixture, which may not ignite. If the heater has not been fired in over a week, chances are there is a blockage in the burners or orifices that is preventing the gas from escaping the burner and reaching the spark.
- Other causes of this problem are: (1) Bad ignitor. (2) Bad gas valve.
I have a large pool pump; do I have to have a flow meter for the heat pump?
- Hayward heat pumps have a flow rate range of 30 to 70 GPM, with an optimum flow rate of 45 GPM. If your pump is capable of significantly more flow than this, a flow meter is recommended to insure the flow rate is within the prescribed range.
What is the coldest temperature during which the heat pump will function?
- 45° - 50° F, If the temperature is lower than 50, the heat pump will cut off and display LP
Will a heat pump heat a spa during the winter?
- Heat pumps derive their heat from the air. There is enough usable heat for a Hayward heat pump to operate, efficiently, down to around 45° Fahrenheit. However, there may not be enough heat available to keep your pool or spa as warm as you would like. If your winter temperatures normally drop below 50°, a heat pump would not be a viable option for heating through the winter.
What are the BTU output and efficiency ratings on the HP2100 Heat Pro?
- The heat pump BTU output and efficiency change as certain variables change. Air temperature, water temperature, relative humidity, and water flow rate all affect the output and efficiency of heat pumps. For comparison purposes we use the following parameters,
Performance rating is 5.0 C.O.P.@
80° air temperature, 80° water temperature, 80% relative humidity and 45 GPM = 116,000 BTU/hr.
What does C.O. P. mean?
- Coefficient of performance (C.O.P.) is a measurement of performance of the heat pump versus electrical input. When electricity is converted from watts to BTU’s of heat, the conversion is 3.4 BTU’s per watt of electricity, which is a C.O.P. of 1. If a heat pump has a C.O.P. of 5, the output will be 17 BTU’s per watt of electricity (3.4 X 5).
How do I drain / winterize the heat pump?
- Turn off the power supply. Disconnect the unions on the water inlet and discharge lines. Tilt the heat pump slightly toward the fittings to insure all the water in the heat exchanger has drained out.
Does Hayward sell a cover for their heat pumps?
- Hayward does not offer a cover for their heat pumps. There are several outside companies that manufacture heater covers. Consult your local Hayward dealer for cover options. A cover is not required.
Is my heat pump leaking water? There are large puddles of water under it.
- There are two methods for testing for a leak on your heat pump.
(1) Turn the heat pump off, but leave the pool pump on to circulate water through the unit. If the heat pump is leaking it will leak whether or not it is running. The water around the heat pump will dry up in a few hours if there is no leak.
(2) Check the water around the heat pump as you would the pool water, with a chlorine test strip. If the water around the heat pump does not show the same level of chlorine as the pool water, then the water around the heat pump is condensation from heat pump operation and is not coming from the pool. If the water around the heat pump tests the same as the pool water, then there is probably a leak in the heat pump.
What is the difference between heating with gas and a heat pump?
- With gas heat, gas is burned and generates heat to heat your pool. With a heat pump, heat is transferred from the surrounding air to the pool water. Gas heaters can operate in almost any climate, and at almost any time of the year. Heat pumps must have heat available in the air before they can heat the pool. Heat pumps are designed to maintain consistent pool temperatures throughout the normal swim season.
