TRV Help

Remote temp sensing and remote temp adjusting TRVs are definitely available but they attach with a fine and rather delicate capilliary tube. You still need to have room for the valve body and the little "head" that will actually operate the valve.

I doubt that any electrically operated device could match the simplicity, accuracy, long life and low cost of TRVs and you'd still have to find room to put some sort of valve somewhere.

    hi i was wondering if there is a trv that works with constant circulation where the thermostat mounts to the wall and adjust the valve automatically for that loop here is what i want to do

    each room in my house is on it's own loop and my baseboards don't have enough room to mount a trv. but i want to control each room.

    my system will be setup with buderus 2107 and the bfu room sensor for the main living area and for indoor feed back. and run on constant circulation.

    is there a trv that i can mount the temp sensor on the wall instead of directly to the baseboard. something like how a zone valve works but instead of off and on it would throttle the flow to maintain temperature for that room.

    i will have add a pressure differential bypass valve connecting the supply and return on the manifold when i do this but that's no problem

    i want to do this because id like to start using constant circulation but don't want some rooms to over heat. right
    now i have one t-stat for the whole house ;-(

    thanks

    i was hoping to put the valve on the manifold like a zone valve and have the t-stat regulate the flow that the loops needs.

    so basically a remotely operated trv where the valve will be attached at the manifold and the t-stat would be in the room controlling how much the valve opens. i will be using constant circulation so a on and off style zone valve wont work for me.

    thanks

    Don't believe that's possible with a TRV. It's possible with a pneumatic system, but you're talking serious $$$$ plus the maintenance headache of keeping a constant supply of nice clean compressed air.

    so there is no way to get the same benefits of a trv without attaching one directly on the side of the incoming loop? my baseboards come up and 90 right on the edge of the walls i have no room to put one on the baseboard.

    i don't really want to remove the fins

    you could

    use one of the Danfoss wall mounted operators with a 26 foot capillary (#013G5068), assuming you could snake the capillary etc back to the manifold and you distance did not exceed 26 feet. The valve body could be located anywhere between your manifold and the actual baseboard.
    Good luck.

    Basically it sounds like you want zone valves, I mean, thermostatically operated, and on the manifold. Sounds like a perfect application for the zone valve. Though I agree, the TRV's sound like a much better option, because a zone valve + thermostat + transformers, etc. to power everything is going to get expensive also.

    Viega manifolds...

    simple thermostats in each room, Viega (or similar) manifolds with their 2 wire zone valves and a Taco ZVC40- whatever you need for the number of zones.

    Lots simpler than trying to snake the TRV remote wires through walls and such. It's also an easy way to add a by-pass at the end of the manifolds. In the long run, it achieves your goal with alot less fuss. Especially if you've got home run piping already. Chris

    Can you loop up into the wall and back down to the baseboard supply?

    If so, you could use a FHV--kind of like a TRV on the wall. Cost is higher since they include integrated adjustment allowing balanced head and a built-in (non-automatic) air purge. Supposedly easy to install. They're really intended for floor heating applications, but would work if you utterly cannot fit TRV bodies into the baseboard.

    darn you would think that someone thought of a thermostatic zone valve :-) more and more people are going for constant circulation this would allow you to control each room the way you want

    thanks anyway guys i will just put the bfu sensor in the middle of my house and have that adjust the temp for all the home run loops
