Table 2.4 Notes:
At 90 degree rise, boiler input (and therefore DHW production) is reduced due to proximity of DHW outlet
1.
temperature to maximum permitted target supply temperature.
Response time is time required to reach specified temperature from a “cold start” with DHW inlet temperature of
2.
58F and a 1.0 GPM draw rate. Additonal time may be required to purge the piping between the Bimini Buddy and
the fixture.
