Wondering if I should install a reset control and a post purge on my new system

dhmeiser

Just had a BIASI FIVE SECTION B10 SERIES BOILER with 35 GALLON BURNHAM STONE LINED INDIRECT WATER HEATER and RIELLO BURNER BF -5 DIRECT VENT installed. Replaced an Energy Kinetics EK-1 which had had a burn through above the burner which warped the steel. it was 22 years old so it was time to go.

The new system uses a ZVC406 6-Zone Zone Valve Control with Priority and a Model 3250 Fuel Smart Hydrostat

I was wondering if it is possible (or worth the money) to install post purge to the indirect water heater and a Boiler Reset Control on the system. Also is it even possible to add those components to the ZVC406 or will that control unit have to bee replaced ?

I am in the Northeast (around Philly) and wanted to get opinions if it is worth the money to upgrade/add these components.

Thanks in advance

Thanks,

Another question, the household system has another hot water tank used for radiant floor heating, it is controlled by an Erie system 3000.

If I understand correctly the 3250 can act as a reset and thermal purge but only with with a single priority zone. Is there a way to set the system up to have two priority zones and utilize the reset control and pre-purge of the 3250?

My concern is that the tank for the radiant heat tank will never reach its set temperature with the reset function operating on the 3250

The 3250 can only purge to one zone. It resets on a time based algorithm,it slowly raises the high limit as the heat call persists so it will reach max temp within a time period that should be almost unnoticeable.
