How To: Size a Gas Heater for Your Swimming Pool

Floating pool dispensers can be used in aboveground and inground pools, but make sure your pool manufacturer says its safe to use one. This level is ideal for swimmers because it isnt so high that it burns the eyes or skin yet helps keep the pool clean. This pH range works well with floating chlorine dispensers.

## How Many Btus Do I Need For A 15000 Gallon Pool

Pool Size
Up To 10,000 Gallons 12′ x 24′ 50,000 BTU
Up To 15,000 Gallons 14′ x 28′ 85,000 BTU

Up To 25,000 Gallons 18′ x 36′ 110,000 BTU 125,000 BTU

In order for 20,000 gallons of pool water to heat 30 degrees you would use the calculation: 20,000 x 8.3 x 30 = 4,980,000 BTU total. This means that it would take 207,500 BTU’s per hour in order to raise this 20,000 gallon pool from 50 degrees up to 80 degrees in a 24 hour period of time.

## Ceiling Mount Electric Heaters

Hardwired into your homes electrical system, a ceiling mounted heater allows your floor space to be used to the greatest degree. These reliable heaters dont have to be constantly plugged and unplugged. Furthermore, they can be installed on a different circuit than your power tools, so youll have no worries about blowing a fuse. A ceiling fan will help circulate the warm air down to floor level instead of letting it all pool up above your head.

For daily pool users, turning the thermostat down a couple of degrees, instead of turning the heater off overnight, tends to be best for saving energy in most situations.

## Water Volume And Time

This is a very popular method for measuring pool heater size, it takes the volume of the pool in gallons and also factors in loss from surface through evaporation.

First, we need to know how many BTUs it takes to heat one gallon of water. One gallon of water weighs 8.34 pounds, and we know that a single BTU is the amount of heat energy required to raise the temperature of 1 pounds of water by 1 degree. So, to heat 8.34 pounds of water we need 8.34 BTUs, which is the amount of heat energy needed to raise the temperature of one gallon of water by 1 degree. Now, we need to calculate the number of gallons in our swimming pool which measures 40 x 30 x 6. The volume is 7200 cubic feet, and when converted to gallons it is 7200 x 7.48 = 53,860 gallons.

We need 8.34 BTUs of heat to raise the temperature of one gallon by 1 degree. Taking our example of a swimming pool in Detroit during September, we need to go from a temperature of 65°F to 80°F which is a 15 degree rise. So, we need 15 x 8.34 = 125.1 BTUs per gallon of water for a 15 degree rise in temperature. Now accounting for the entire volume of our pool, the total heat energy required is 125.1 x 53860 = 6,737,886 BTUs. Thats a whole lot of heat energy, right? Clearly there is no company on Earth which will sell you a 7 million BTU/hr. pool heater. So, lets do this over a 48- hour period which sounds reasonable- 6,737,886 BTU spread across 48 hours is 140,372 BTU per hour.

## Types Of Pool Heaters

When you consult with a swimming pool professional, the first thing they are going to ask you is how quickly you want your pool heated. And then, they will examine the location of your pool as well as its surroundings. Are there any trees blocking direct sunlight from falling upon the pool? Do you have shrubs, fences, or cabanas around the pool to restrict wind speeds? And how large is the pool, how many gallons of water does it hold? The answers to these questions will help you determine the best type of pool heater for your needs.

Gas-powered pool heaters: If your pool is large, and you want it to heat up fast there is nothing better than a propane or natural gas-powered pool heater. Most people get a 250,000 BTU gas heater if they can accommodate it within their pool heating budget. What makes a gas heater so unique is that it can actually extend your pool season, maybe even double or triple the number of months in a year that you are allowed to use your pool. For a city like Detroit, swimming season is usually the 2 month period consisting of July and August. But with a decently powerful gas heater unit, you can easily extend it on both ends as early as June, and as late as September.

• Circular pools: radius x radius x 3.14
• Kidney-shaped pools: length x width x 0.75
• Oval-shaped pools: x x 3.14
• Rectangular pools: length x width
• Calculate the required BTU output per hour: surface area x temperature rise x 12
