with the advent of primary/secondary, closely spaced tees, injection pumps, etc., it behooves us to sprinkle the system liberally with pressure/temp gauges so that we can easily see the delta-P's & delta-T's, and set the flows accordingly, you can design and calculate from today till
doomsday, and the actual system will still behave differently, especially as it ages - it needs to be designed for controlability from the getgo,
- the other choice would be to use TEKMAR controls throughout with their mixing/flow valves and variable pump controllers - which is great, if you have gobs and gobs of cash!!! - cause unless gas tripples in price, the 30yr the energy savings wont cover the install and 30yr maintenance/repair costs

enough talk, what i need recommendation of quality pressure/temp gauge, for copper pipeing environment, where do i buy them in bulk, and what is the avg cost?

thanks, kal

    My suggestion would be

    to use pressure/temperature test plugs. They are inexpensive, available in 1/4" or 1/2", and will allow you to check both the temperature and the pressure at the same point with a single gauge equipped with an adaptor fitting or a bimetal thermometer. The ones I use are made by Trerice, but there are others available.
