Gas heaters are low emission and take up little space. They heat the pool quickly in any weather, allowing for year-round swimming and enjoyment. They are the cheapest to purchase. Clearly, gas heaters are the perfect solution for pools in cold climates.


What type of heater is right for you?

There are many reasons to consider purchasing a heater for your pool, the most logical being that you want to get more use out of your pool. Heated pools get more usage, plain and simple. Most people find a temperature between 78 and 84 degrees ideal for swimming. In the cooler months when temperatures drop your pool will be much colder than that.

Even in warm climates pool temperatures can vary based on a variety of factors; including rainfall, location and the amount of sunlight that it receives. If you live in a cold climate, you may want to extend your swimming season by buying a heater for your pool, but which is the right fit for you?


What is a BTU?

First, let’s explore what makes one heater different from the other. Heaters are measured by BTU’s. BTU stands for British Thermal Unit, and is defined as “the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.” Put simply, in large pools or cold temperatures, your heating unit is going to require a higher BTU output to heat the water. 


What are the Advantages of a Gas Heater?

Pool gas heaters generally have high BTU ratings, meaning that they raise water temperature quicker than any other type. This is perfect for cooler climates because they can heat pools in cold weather in a short amount of time. Gas heaters can be turned off and still heat the pool on short notice, although this may result in high energy costs.

This still makes them ideal for weekend use, when guests arrive, or with second houses or vacation homes. Some models have thermostats to regulate the temperature. Gas heaters can also run in any weather, even windy conditions. Essentially, a gas heater will enable you to swim year-round!

Gas heaters are popular because they are effective. They are often used specifically for hot tubs, and many people enjoy the ability to heat their spas on short notice. Certain types have separate elements that allow you to choose the temperature of both your spa and your pool.

Gas heaters do not need much space and take up a relatively small footprint on your existing concrete pad. Gas heaters can run on either natural gas or propane. This makes them flexible because you can choose either type, depending on what works for your home and your area.


What are the costs?

A gas heater will cost you significantly less initially than either a heat pump or solar system. Most gas or propane heaters will cost a few thousand dollars. Propane and natural gas prices vary, so check with your energy provider. These factors, plus the weather where you live and the amount of time that you use your heater will ultimately determine the cost of running it.

Keeping your pool water balanced will help to extend the life of your heater. You can reduce your monthly expenses by using a solar pool mat or blanket, or by using Suncoast Solar Trap Liquid Solar Blanket. Solar covers help to trap the heat in your pool, extending the usage time and reducing heating costs. Think of the blanket like a lid on a hot beverage, it keeps the heat in.
