The purpose of a spa pool is to provide a relaxing environment and as a result it is usual to have a system for heating the water to a comfortable temperature. Spa pool 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 a spa pool is heated is 97 to 102 degrees. This is considerably higher than the normal temperature of a swimming pool but spa pools 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 common being gas heaters which use either natural gas or propane to heat the water. Many heaters such as the Raypak 2100 can be used to heat a spa or pool (or both). In a gas heater the water is channeled through a heat exchanger and then back to the pool. A similar type of spa pool heater is the oil fired heater but it burns diesel as a fuel instead. Your choice of fuel type may be determined by your domestic heating, for example if you are already storing diesel for that purpose then it may be sensible to also use it for the spa heater.
An alternative is an electric spa heater. The electric heater has a slower heating and recovery time than the gas heater and it requires a high amp circuit to operate. Because of this, it is only advisable to use electric heaters on smaller spa 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.
Because they minimize costs and have green credentials spa pool heaters that are more environmentally friendly are becoming popular. Among these green spa pool heaters are the solar heater and electric heat pumps. Solar heaters gain heat from the sun through solar panels and are controlled by a time clock and thermostats. A compromise is to use these in conjunction with some other type of heater to reduce the fuel used by that heater. Meanwhile a heat pump uses the warmth of the surrounding air to generate heat. Heat pumps are extremely efficient but they are low powered compared to other types of heater and are reliant on the temperature of the air.
With so many options for a spa pool heater nowadays, anyone can choose a suitable heater or perhaps a combination that will be appropriate for their budget and needs.
