Well, it’s just mid-October and there’s already snow at the ski areas in our neck of the woods. To extend your swim­ming sea­son, there are options avail­able that will help you heat your pool in the win­ter months.

Here are your options:

Gas Heater

Gas heaters heat your swim­ming pool by burn­ing either propane or nat­ural gas. They can heat your swim­ming pool more eas­ily and quickly in lower tem­per­a­tures than a heat pump, which oper­ates less effi­ciently in lower tem­per­a­tures. The gas heater is great if you want on-demand heat.

Air-Source Heat Pump

Air-source heat pumps are rapidly grow­ing in pop­u­lar­ity because they offer very energy-efficient and cost-effective heat­ing. Air-source heat trans­fer heat from the air to your swim­ming pool. They have a COP mea­sur­ing between 5 and 6, which means they pro­duce five to six units of energy for every unit they con­sume. This high energy effi­ciency directly trans­lates to low oper­at­ing costs and low envi­ron­men­tal impact.
Most heat pumps shut down when the out­side tem­per­a­tures go down below 55° degrees, some can con­tinue to oper­ate down to the mid to low 40’s, and some can oper­ate in tem­per­a­tures of mid to low 20’s. These types of heat pumps have dif­fer­ent names and are made by var­i­ous man­u­fac­tur­ers they can be referred to as reversible heat pumps, heat/cool heat pumps or ice­break­ers. On colder tem­per­a­ture days, a heat pump will begin to “freeze” the con­den­sate that forms nor­mally on the evap­o­ra­tor coil. Stan­dard heat pumps sim­ply turn off at this point to avoid mechan­i­cal dam­age to the heat pump sys­tem due to this icing con­di­tion. A Hot Gas will uti­lize a reverse cycle process which reverses the flow of refrig­er­ant gas through the unit, quickly “defrost­ing” the evap­o­ra­tor coil– which allows the heat pump to con­tinue to heat

Water-Source Heat Pump

Water-source heat pumps are not as well-known as other heat­ing sys­tems because they uti­lize newer tech­nol­ogy. They trans­fer heat from water sources, such as a lakes, ponds, or wells. Water-source heat pumps greatly ben­e­fit swim­ming pool own­ers who live in cli­mates where air tem­per­a­tures fall below 50°F (10°C).

 

The instal­la­tion of water-source heat pumps requires large wells and long water lines. This instal­la­tion process can be both timely and costly. How­ever, after the instal­la­tion process is com­plete, your water-source heat pump will require min­i­mal cost and space.

Solar Blan­ket Solar blan­kets are often rec­om­mended because they greatly reduce swim­ming pool heat­ing costs. 75% of your swim­ming pool’s heat loss is due to evap­o­ra­tion. A solar blan­ket reduces heat loss from evap­o­ra­tion by act­ing as a bar­rier between your swim­ming pool and the air. A solar blan­ket is most effec­tive at night and dur­ing cloudy days, when the poten­tial for evap­o­ra­tion is greatest.
