Ok, I am a homeowner trying to do my own heating work. I have an older 2 story home and I want to hook up 2 zones, one for ground floor and one for upstairs. So, I went to Menards to get a couple zone valves, but when I looked at them I see that even though they are 3/4" sweat connectors, with the valve inside the opening is more like 1/2 inch so.
My question is this, if a 3/4" line can carry 40, 000 or so BTUs of heat, will this zone valve, by the way the valve restricts the flow, reduce the heating capacity? Or , will it still allow the full volume of water as the 3/4' pex?
