TRV brand recommendations

diesels12

I am upgrading large house with 12 risers and 30 radiators. Thanks to the advice on this board I will be using TRV'S to regulate radiators with constant circulation pump (s). Since I will be buying so many TRV's I want to make sure I get the right brand and not have to worry about changing them every couple of years. Each one will also need a remote sensor to measure room temp since radiators are enclosed in boxes for aesthetic reasons. Any suggestions?
Also was curious as to the how many pumps I will need and piping advice, house is big with long runs. We will be using 1" pex to base of each riser and also return keeping existing metal vertical pipes in wall. All will home run back to boiler giving me 12 feeds and 12 returns. I am not doing the work but want to be able to tell HVAC guy exactly what I want. Most just want to do zones and thermostats.

Cheers

I suggest Danfoss for the TRVs. As far as how many circulators, we would need to know how many zones. We might also suggest using (1) properly sized circulator and zone valves/actuators for the individual zones. If you're piping the radiators/risers in homeruns, we'll then that's your answer. Another option would be 2-pipe, reverse return.

I’d go with Macon from Tunstall. Tunstall is as good as it gets when it comes to customer service.

Thanks for the recommendation Dan. Called Tunstall and talked directly to the owner Woody. Knowledgeable and helpful guy. My 32 valve bodies with thermostatic sensors are on the way! Will post pics of install when completed.
