Although there has been an emergence of new and more energy efficient swimming pool heating systems, gas pool heaters remain the dominant system used for heating swimming pools. There are two variants of the heating systems that run on gas. These are:
– Natural gas burning systems.
– Propane burning systems.
The natural gas heaters are by far the most popular variant of the two systems since the majority of homeowners have a piped natural gas supply. In addition to this, their installation is simple and their running cost is much lower when compared to propane heating systems.
Propane systems are ideal for homeowners with no access to natural gas supplies. The system necessitates the installation of a propane tank to store the propane which drives up the installation cost. The tank also must be refilled every so often, which also contributes to the running cost.
How Gas Pool Heaters Work
The system is designed to heat water as it circulates through the heater. The gas is burned in a combustion chamber which burns gas to heat up the water. The water is then pumped back into the pool.
Factors To Consider When Choosing A Gas Heater
Pool Size The Size of the pool determines the heating capacity of the gas heating system to be used. As you would imagine, a large pool requires the use of a heating system with a high heating capacity.
Altitude You should choose a heating system that is designed to function within your altitude range. Most systems are designed to operate within the 0-6000 range. If your home is higher than that, you should look for heating systems that are designed to operate in higher altitude ranges.
Durability For purposes of value, you should look for a heating system that is durable. The heat exchange unit should be of high-quality and be capable of withstanding salt and pH fluctuations. The best ones are made of cupro-nickel (CU), which protects against corrosion.
Other aspects to take note of include the types of thermostat used (single or dual thermostat), the ignition types (electronic or millivolt ignition) and the thermal efficiency rating of the system. For example an 84% efficiency rating, means 84% of the energy supplied (gas) will be burned up and used as fuel, and 16% will be lost in the burning process.
That means for every $100 of fuel, $84 of it will actually be used and transferred to your pool as heat.
The Advantages Of Using Gas Heaters
One of the main advantages of using gas heaters is the capability of the heating system to maintain the desired temperature regardless of the climate or weather. In contrast, alternative heating systems such as solar heating systems and heat pumps (electric powered) are not capable of maintaining a specific temperature range.
Another advantage that this system holds over other heating systems is its capability to heat the pool much faster. Solar heating systems and heat pumps heat swimming pools at a much slower rate. This makes the gas heat system the best option for heating swimming pool in the shortest time span possible.
