hydronic valve actuators

heatpup

hello all, I finally installed my radaint floor. Man what I have missed !!! My comfort level is up and my family LOVES it! My DHW need is met and I am hoping to save on energy. I took 2 forced air units and 2 hotwater heaters off line with just one modulating munchkin 140M and an indirect. It was 10 below here for a week and we were very comfortable. I now want to automate and have each room for each kid on its own circuit. It is plumbed this way but I don't know where to buy zone valve actuators or powerheads as some people call them at a decent price. Can anybody help me out here?
thanks for all your posts and information over the last year.

Manifold

Zone valve actuators are not generic; you have to buy actuators made by the same company that makes the manifold.

I use Rehau manifolds and as far as I know, only Rehau actuators will fit on these manifolds.

So what kind of manifolds do you have?

Some do, some don't

manifolds with BSp (I think) threads will accept various operators. I have used Watts Radiant CazzBrass and Stainless Dumser manifolds with Honeywell and Cazzaniga operators.

Recently I have been messing with this OV stainless manifold. It, too, accepts various brands of actuators.

Pretty sure Wirsbo, and some others, have unique threads and require their operator.
