Dedicated DHW Circ
@ August 13, 2009 6:41 PM in Indirect hw tank separate circ?
Here is a zone valve system with a Taco 00 VDT driving the zone valves, an IFC circ for the boiler pump and an IFC for DHW. With a lot of modcons now, the boiler pump will drop off when the (P2) DHW circ takes priority.Click on the drawing to enlarge it.

The pdf I previously tried to upload, didn't.I'll try it again.
Are the bugs worked out on the new Wall, and is that preventing me from uploading pics at this time?

Generally speaking, I will still use a dedicated DHW circ as my boiler has terminals for boiler, DHW, and system circulator. It makes it easy on a DHW call in that the boiler pump will drop off and the DHW will assume priority.I use Taco IFC circulators for my boiler pump and DHW pumps.
