Assuming a 10 degree F temp rise from inlet to outlet at 50 gpm, the heat power is 50 x 60 x 8.34 x 10 = 250,200 btu/hr.

Maybe break it down into standard shape like circles and rectangles. Below is 3 circles and one rectangle. Figure out the diameter of each circle and the dimensions of the rectangle. Multiply the area of each by the depth of each section.

How about some actual facts about things like pool size, flow rates, water temp unheated, water temp heated, pump, filter, surface area, air temp, covered or uncovered, kept heated or heat on demand etc.?

The EasyTouch reports actual salinity. What is the salinity reported? What test kit? What is the cell temperature? Show the sticker on the back of the cell. Check the cell for scale and clean it if necessary. Check the amperage (DC).

HEAVY DEPOSIT REMOVAL. Lower water level to below the deposit line on the tile, but not below the bottom of the tile. Chip or scrape off thick or heavy nodules of calcium carbonate. Squeeze a line of SR3 just above the water line and allow it to sheet down over the remaining deposits. Use a...

The new model reports amperage, which corresponds to production of chlorine. However, it would be easy enough to report the amount of chlorine generated in any specified timeframe.

In my opinion, all SWGs should report the chlorine output. Even if the cell is not generating at full power, some generation is better than no generation. Even if the cell produces only half of the expected chlorine, that is still useful. Of course, it helps if the customer knows that the...
