Heat pumps do have quite a few moving and electrical parts so it is a good idea to have them serviced yearly to get the best efficiency and lifespan out of them. Your user manual will normally have a recommended maintenance schedule. With proper maintenance they should last 10 years or more. Proper balance of your pool chemicals is vital otherwise damage could result and efficiency will drop.Do a little homework before you commit to one type of pool heater over another. They can all sound great on paper but a little thought about your particular needs and situation could help you make the right decision. Heat pumps have some great advantages to consider and some disadvantages too.

The efficiency which is talked about in relation to heat pumps is also called Coefficient Of Performance or COP. This gives a relation between the amount of energy used to the amount of energy produced. To compare apples with apples, a common electric immersion heater (such as in a kettle) is around 90% efficient so would have a COP close to 1 but heat pumps can be rated with a COP of 5 which means an efficiency of 500%. This is because heat pump don't actually create heat (like an immersion heater does) they just move it from one place to another. A swimming pool heat pump will take heat from the surrounding air and move it via refrigerant gas and a compressor to a heat exchanger releasing the heat into the pool water flowing around it. The cooled gas travels on through piping back to where it started and picks up more heat and so on. This is also called a "closed loop" because the gas keeps on traveling around it.

Will a solar pool heater extend your swimming season enough? If you have the space, a solar system may be best even though it could cost more to purchase initially.A heat pump will heat your pool water on demand so you don't have to worry about overcast weather as you do with a solar system. Usually you would set the required water temperature and the heat pump will run as needed to keep to that temperature. They can be used to heat a pool from cold if you only want to use the pool occasionally but gas heaters are better at this.The running cost is about half that of a gas pool heater. The running cost can be reduced by about 60 to 80% if you use a pool cover. Pool covers not only help keep debris out but keep water in by reducing evaporation. Evaporation accounts for around 80% of pool heat loss so installing a pool cover should be very high on your to-do list! Depending on where you live you could expect your power bill to increase by about $700 to $2,000 per year without a pool cover or $100 to $400 if you use a cover.
