    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.
