Bypass with thermostatic valve?
Ok this is one of those DIY’er questions so bear with me…
Background: Peerless WBV-03 connected to old cast iron rads. System water volume is approx. 100gal. No zones. New parallel piping to radiators (i.e. not gravity).
I’d like to install some boiler protection because of the high water content(although there is no mention of this in the Peerless manual???). P/S piping doesn’t make much sense to me because there wouldn’t be any zones on the secondary so essentially the P/S would act like a system bypass. That is, assuming both pumps came on at the same time.
I was thinking of a system bypass, with a manual globe valve in the bypass followed by a thermostatic valve with a remote sensor attached to the return. I read about this somewhere but can’t find it again. The TV would close off the bypass as return temps came up and the manual valve would throttle the bypass loop so there would be some system flow initially.
What are the down sides to this setup?
Where do I find a simple thermostatic valve with remote sensor? I can only find the 3-way mixing type.
