So turned on the heater and see
water to exchanger 160
water from exchanger 115
water from pool 68
water to pool 72
160 degree water only raises temp of outflow 4 degrees?
if water to pool is 72, how will it ever get to 85? or does it add 4 degrees to whatever enters, i.e.
when pool water is 69 out flow will be 73, when pool water is 70, outflow will be 74, etc
exchanger is 260 BTU as in the sig below
