RE: pool heater

The banging is due to an inadequate flow through the heat exchanger. This can be due to either the internal bypass failing/failed or the heat exchanger is loaded with calcium.

I cannot recommend putting a new heat exchanger in this heater, if that is what it needs. Heat exchangers are quite expensive.

I strongly suggest you replace this heater with either a Rheem/Ray Pac or a Pentair MasterTemp, both of which will provide you with a considerably more reliable use than the old NT series.
