Hello everyone.
I've had my WG installed for about 2 weeks now. I have some questions on the installation and was wondering if you could all give me a hand with some things.
A few things. My WG is installed in an insulated room in my pole shed that is 100ft from my house. The water goes through 1" thermopex into the basement where all the other HVAC items are. I'm heating my 2600sqft home on one zone (I'll be dividing this up this summer, it was trial an error on my part), and also heating my 1000sqft garage. I think the E140 is a little overkill, but, I'll be finishing my basement in the next few years and didn't want a possibility of needing a larger wood boiler.
What is supposed to happen is the hot water from the WG is supposed to flow through my Weil Mclain GV90 so that the GV90 doesn't fire when a zone calls for heat (because it should see hot water already). Then it goes to my manifold and from there a pump is activated when a zone calls for heat. The way the installer hooked it is that the WG hot water is going into the boiler through a "T" fitting that is just below the PRV and the return water is coming from a T at the return from the GV90. I want it set up in a way so that in the event the wood/fire goes out that the GV will automatically pick up the slack.
The problem is that the water at the WG is 180-190 and I'm only seeing ~150 just before the manifold. I don't think things are hooked up so I'm getting the most efficiency. What I think is happening is that the pressure from the GV boiler is pushing the water back through the supply line on the WG, thus keeping most of the 180-190 hot water from getting to the manifold.
What I think needs to happen:
1. install Danfoss valve on the boiler side, before the thermopex for boiler side protection (right now there is no way of knowing the return water temp).
2. Install a backflow preventer where the thermopex comes into my basement (before it enters the GV).
3. Install a "T" before the GV but after the backflow preventer so some of the hot water goes into the GV but some also bypasses and goes into the manifold.
My schematic may suck, I did it hastily in PowerPoint. This is how it is currently hooked up.
Here is a schematic on how I think I should hook it up to improve my manifold temperatures and also to include the return water protection valve (Danfoss).
