Why is my HTP SSC-50 not producing enough hot water?
There could be several reasons why your HTP Water Heater isn't providing enough hot water. These include a zone valve restriction (replace zone valve with a 1” full bore), a reversed circulator arrow (reverse the circulator), or a boiler temperature that is too low (raise the boiler temperature). Other potential causes are: the boiler or tank being too small (check sizing chart), a demand flow rate that is too high (check sizing chart), an air trap in the loop (purge to remove air), the heat and tank coming on together (recheck wiring or coincidence), not enough space heat (boiler sized too small - consult chart), or a slow recovery (circulator head capacity too low).
What to do if my HTP SSC-50 has no hot water?
If your HTP Water Heater isn't producing any hot water, several factors could be the cause. These include a zone valve not opening (check or replace), a circulator not operating (check or replace), a tank control set too low (raise tank temperature), a boiler control set too low (raise boiler temperature), incorrect wiring (recheck wiring), a tank control failure (replace control), or an air trap in the loop (purge air).
