In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Zone Valves versus Zone Pumps
Still waffling between zone valves (5 zones) and zone pumps (5 zones as well). For the zone valves I would use a variable speed ECM pump. This project is on a tight budget. It would appear on the surface that the upfront costs for the zone valve configuration would be a few hundred dollar differential. Is there a significant electrical savings for this type of control? What percentage savings might one expect?
Are there quality zone valves that are less expensive?
