Does a pool heater need a regulator?
Almost all pool heaters have a gas pressure regulator, which is both preset and sealed to prevent accidental changes in gas pressure. Do not attempt to change or open the gas pressure regulator on the pool heater, as this may cause a gas leak or even a potential explosion.
How many BTU do I need to heat my spa?
Tips for do-it-yourselfers Number of gallons x 8.33 (pounds per gallon) x the temperature rise = the number of BTUs required to heat the vessel. For example, consider a 40-degree temperature rise in a 400-gallon spa — that is, 400 x 8.33 x 40 = 133,280 BTUs.
How big of a pool heater do I Need?
Therefore, the minimum size heater that is recommended for a 15 x 30 pool is 150,000 BTUs. This is simply the recommended minimum size. I always go higher. Especially when it comes to gas heaters, you always want to oversize the unit.
How long does a gas pool heater take to heat?
The 175,000-Btu heater would take 28.45 hours to accomplish what the 207,500 Btu heater can do in only 24 hours. This is actually how a solar heater (or an electric heat pump) works to heat a pool. Unlike gas heaters, they have much lower Btu output potential, nowhere near to 200,000 Btu per hour.
Which is the most powerful type of pool heater?
The concept of Btu ratings applies to all forms of pool heaters: Gas pool heaters and propane pool heaters are the most powerful heating units available for residential pools. These units have the highest Btu output, ranging from 100,000 up to 500,000 Btu in some areas (400,000 Btu in most parts of Canada and the U.S.).
Which is faster to heat a pool 400K or 200k?
It is true that larger heaters heat your pool faster than smaller ones. A 400k BTU heater will heat a pool twice as fast as a 200k BTU heater and burn gas twice as fast. Heating up a pool versus a pool/spa combination requires less BTU power.
Therefore, the minimum size heater that is recommended for a 15 x 30 pool is 150,000 BTUs. This is simply the recommended minimum size. I always go higher. Especially when it comes to gas heaters, you always want to oversize the unit.
What makes up the output of a pool heater?
Most heater sizing charts assume a 24-hour Heat Up Time. The heater Output, or BTU, is the energy that the heater will transfer to the pool water. The heater Input is the energy, still in BTU’s, that is used to generate the output heat.

Do you need a breaker for a millivolt pool heater?
Power: You can still buy a millivolt heater, which requires no power supply, but wiring a digital heater is easy. You don’t need a separate breaker, you can tap power from the timeclock or pump switch. Use 220V or 110V, and follow the instructions to connect power inside of the heater.
