Jacuzzi heaters not only provide a comfortable soothing experience that is perfect for unwinding after a long day, they also extend the season of the spa pool so that they can still be used during a cold weather.
The normal range to which such a pool is heated is 97 to 102 degrees. This is considerably higher than the normal temperature of a Jacuzzi (בריכות ספא) but spas are much smaller, typically not more than eight square feet and less than four feet deep. As a result the requirements for a heating system are less than those of a swimming pool.
There are four main types of spa pool heaters that are available today. The most popular ones are gas heaters which use propane gas or natural gas to heat spa pools. Jacuzzi (ג׳קוזי) heaters like the Raypak 2100, Raypack Millivolt and Laars Lite can also be used to heat spa pools. In a gas heater the water is channeled through a heat exchanger and then back to the pool. An oil fired heater is very similar but uses diesel as the energy source.
Another type of Jacuzzi (בריכות ספא) heater is the electric heater. These heaters heat the water more slowly than gas heaters and are not cheap to run. Because of this, it is only advisable to use electric heaters on smaller pools to save on the heating costs. Electric heaters work in much the same way as gas heaters in that they heat the water directly.
