How do I calculate BTU for gas meter?
For example, if the heating value is 1,050 BTU/Cu. Ft. and you timed 1 cubic foot of gas at 42 seconds then firing rate BTU/Hr. = 1050 x 3,600 ÷ 42 which calculates to 90,000 BTU/Hr.
How do I calculate the BTU of my pool heater?
The pool’s surface area divided by three gives you the minimal BTU size recommended for that particular surface area. Continuing the example above with the 15 x 30 pool, after dividing by 3, you get 150. Therefore, the minimum size heater that is recommended for a 15 x 30 pool is 150,000 BTUs.

How big of a gas meter do I need for a pool?
Suz. With the addition of a 400kBTU/hr heater, most standard residential meters are not large enough. Few household appliances (tank water heaters, forced-air gas heaters, gas stovetops, etc) consume as much gas as a pool heater.
How big of a gas line do you need for a pool heater?
It is also advisable that your gas line run from the main to the heater either be a single run with no stubs off to other equipment (like a BBQ grille) OR that it be a large enough diameter to accommodate all devices on the line. You don’t want to turn on a gas grille or fire pit and suck all the gas away from a heater.
Can a pool heater use as much gas as a stove?
Few household appliances (tank water heaters, forced-air gas heaters, gas stovetops, etc) consume as much gas as a pool heater. As well, most pool heaters have very tight inlet pressure requirements and, if the meter is too small, a sudden drop in gas pressure will cause the heater to shutoff.
How big of a gas pipe do I need for a water heater?
You can see that, in a typical gas system, a tankless water heater with a capacity of 199,900 BTU will require a 1-inch pipe size for a 20 ft branch length (based on the 0.3 in w.c. pressure drop in Table 2). The same appliance would require just a ½” pipe size based on Table 4 the 3.0 in w.c. pressure drop.

How big of a gas pipe do you need for a pool heater?
The solution was to upgrade to a “2 pound” system. The gas company installed a different meter which outputs gas at 2 PSI. The piping from the meter into the house was still 3/4″, but there is a regulator at each appliance (furnace, stove, pool heater) to drop the pressure. The project took several days and lots of $$.
How many BTUs does a pool heater need?
Current pool heaters are 85% to 90% efficient. This means if you have a heater with an input of 400,000 BTUs, you’ll be getting 340,000 BTUs of output based on 85% efficiency, though this drops over time due to normal wear and tear. Understanding BTU’s helps you determine the necessary heater size for the volume of water in your pool.
