What TRV

mel rowe

I recall that Dan always recommended TRV's with a built-in vacuum breaker. I'm sure it also depends on your steam system characteristics, but I had trouble on mine using the Honeywell-Braukmann TRVs, which do not have a vacum breaker. The condensate would gradually build up in the valve body and air vent, and not flow back, eventually blocking air flow and causing lack of heating. A Danfoss TRV I tried in the same location has worked fine. FWIW

Macon Controls

"NT" series, I personally like. Seem slightly smaller, more tapered and less bulky than others. Work well and very available through Tunstall Inc.

Good variety of heads, direct, remote sensing, remote setpoint with remote sensing, etc.

Any particular reason?

Why the macon? I have a few Danfoos, brand new, that I had planned to use when changing boilers. After all, they were free, so I figured they were the way to go. So if there's a reason you prefer the Macon, please let me know. I'm always willing to expand my knowledge.

In my initial response

I intended to cover that when I wrote: "Seem slightly smaller, more tapered and less bulky than others. Work well and very available through Tunstall Inc. Good variety of heads, direct, remote sensing, remote setpoint with remote sensing, etc."

In particular, I like the finish but the overall mass is less than others. The control heads including the remote types are also fairly small compared to other brands I have used. They of course work well and are accurate as a given for any valve. Many of my clients like them to be discrete and unobtrusive.

Another feature I like is the use of an Allen wrench rather than a spud wrench for insertion. Valves that small (nearly all I use are 1/2" for a typical radiators), benefit from that feature, especially in tight spaces.


Nothing against Danfoss or the others, really personal preference based on trying nearly all brands over the years.

I actually like...

the Honeywell ones. I have used them on a couple of converted gravity systems and the have the larger sizes and configurations. FWIW. kpc

This is a case where it really doesn't matter. They all work well and they all last a long time.

People may have difficult-to-explain gut reasons to prefer one to the other, but it's not like Consumer Reports saying "Brand X needed the most repairs, Brand Y the least". You'll rarely get a complaint about TRVs.

So use the one that's easiest to find in the required size, or the one you already have.

Thank you

Thanks Dan, I just had to ask,was concerned I might otherwise miss something. By the way, I too like the aesthetics, compact yet rugged looking. So I will use some of the Danfoos, and I shall try the Macons also.
