Is the Btu rating of a pool heater the input Btu of the gas or the transfered Btu going into the water?
input of gas heater
The heater has its own BTU rating separate from the gas and the heat transferred. Every heater has an efficiency rating... for instance, a heater can be rated at 92%. This means that for every BTU burn in the heater, 92% of that BTU is transferred in to the water. The main premise behind BTU ratings and Pool Heating is that most forget the parallel factors involved. How many gallons, and what is the temperature rise?
A 200k heater and a 400k heater can both handle, maintain, and work at the same efficiency. The true difference in them is the time it takes to create the rise in temperature. If the pool is 60 degrees, and you want the pool 80 degrees, then you'll need 1 BTU to raise each pound of water 1 degree. The only remaining variable is the quantity of water which will tell you the total weight of the water.

What size pop up valve do i need for my hot water heater?
That would depend on the size and heating capacity of the water heater. You need a temperature and pressure relief valve ( not a pop valve which is pressure only) with an ASME rating at or above the input rating on the water heater. For example: a domestic, gas fired, 40 US gallon water heater might have 36,000 BTU per hour input rating. The pressure relief might be set to 125 or 150 psi, but the temperature rating would have to be at least 36,000 BTUH. A 3/4" T&P relief valve typically is rated at 100,000 btu per hour. If you are dealing with a larger unit ( a 50 or 60 gallon tank, or a cyclone ) you will have to check the rating plate to get the proper relief valve.

How do you calculate the efficincy of gas burner?
Divide the output rating by the input rating
Can you use a step up transformer 110220 with output of 16 kva?
Yes, but your input current is going to be high at 133 amps. The output of the transformer is not going to be 16 KVA, that is the rating of the transformer.

How do you determine the operating costs for an above ground gas pool heater?
Your gas pool heater should have a BTU/hr rating for input and output printed on a placard somewhere on the heater. Look for the input rating and divide by 100,000 to get Therms/hr. Assuming your gas is being billed in dollars per Therm, just multiply that rate by your Therms/hr. to get dollars/hour. Multiply this by how many hours you run your gas heater and that's your total pool heater operating cost. Also take in account the time of year temp and wind. If your heating your pool to 78-85 degrees and your pool water is 60 degrees that would be an 18-25 degree temp rise. Your pool is exposed on all sides and this will bleed heat off quickly. It may never achieve the temp desired or not shut down and always call for heat.

What is wattage rating of microwave oven transformer also hi voltage from secondary?
The rating is about 1500W. This is for both the input and the output. Output voltage is usually 2,000 volts. Divide watts by input volts to get input current. And divide watts by output voltage to get output current. -Joe
How do you find the efficiency of your furnace?
Divide the btu output rating by the btu input rating. Both of these values can be found on the furnace`s nametag.
