See How We Replace Gas Pool Heaters Like Pros

Ever wondered what goes into a pool heater installation? Spoiler: It’s not just plugging something in and hoping for warm water. At Great Falls Pools, we recently filmed a full behind-the-scenes look at one of our most common service calls. We removed an old gas pool heater and installed a new one, start to finish.

If you’re thinking about adding a pool heater or replacing an old one, this video is for you. And if you’ve ever asked, “Who installs pool heaters around here?”, the answer is right in your backyard.

In this featured video, we walk you through the full process of a gas pool heater installation. From unhooking the old unit to setting up the new one, you’ll see every step. That includes safety checks, plumbing updates, and the moment the new heater fires up for the first time.

We take our time to do it right. We also explain what we’re doing and why it matters. Even if you’re not the DIY type (and we don’t recommend trying this yourself), you’ll come away with a clear understanding.

Why Gas Pool Heaters Are a Favorite in Virginia
When it comes to swimming pool heater installation, there are a few popular options. According to The Swimming Pool Store,

“Two of the most popular types of pool heaters are gas heaters and electric heat pumps. Gas heaters, which run on natural gas or propane, provide rapid heating and are ideal for sudden temperature changes or colder climates, making them a top choice for homeowners in regions like Connecticut. Heat pumps, on the other hand, use electricity and are highly energy-efficient, making them perfect for maintaining consistent temperatures in milder climates.”

Here in Virginia, our climate is generally mild. But we are no strangers to wild swings in temperature. It can be 70 degrees one day and 50 the next. That kind of change makes a gas heater the go-to choice for many homeowners. It heats fast and keeps your pool comfortable no matter what the weather decides to do.

Thinking of Adding a Pool Heater?
If your pool sits unused in cooler spring or fall weeks, a heater can change that. Adding a pool heater gives you more swimming days and warmer water when you want it most.

It is perfect for early-morning swimmers, kids who want to jump in year-round, or anyone tired of that cold-water shock.

And yes, we handle both new installs and full replacements. If it heats pool water, we know how to work with it.
