How much heat is actually going into your pool? Today, we’ll show you how you can answer that question yourself.
Starting at 0:15 in the video above, you’ll see a two-page chart of some common gas heater brands and their features. These are the main brands available for pool owners in Florida, and there are a couple of things you need to know regarding BTUH ratings for these units.
First, a BTUH rating measures the unit’s heat input, not the heat output. In other words, that’s how much fossil fuel the unit is burning, not how much that’s going into the pool. If you want to know how many BTUHs are going into your pool, you need to multiply the efficiency rating of the heater by your heater’s BTUH rating.
For example, a 400,000K BTUH heater is a common heater for a commercial pool, and a 400,000K BTUH heater at 82% efficiency equates to a 328,000 BTUH output per hour.
No matter what heating unit you use for your pool, you need BTUHs to do it, so you need to know how many BTUHs are going into the pool versus how many BTUHs of gas the unit itself is burning.
As you’ll notice, some of the other categories of the chart include Low NOx and Fan-Assisted. A Low NOx rating is important for your heater from an environmental standpoint, and a Fan-Assisted feature basically means your heater is turbocharged.
