HI All I need help, I am buying a house for the mother in law and BF and I would like to add 2 TRV's to the system, here is what I have. 2nd floor,3 bedrooms and a bathroom, thermostat is in master bedroom, total sq foot of 2nd floor is aprox 700 Sq feet, Hydronic slant finn baseboard heat all on a single zone. i would like to install a TRV and bypass on the 2 bedroom's without the thermostat. by doing so i can keep the doors closed in those room's and keep the temp down to around 60 degrees if need be, and with a bypass all the hotwater flow not needed to the basboard can still be used down stream to the other registers. I need help on exactly what TRV/bypass i need. I talked to my plimber and he just looked at me with a deer in the headlight stare, I am in northern mainr and beleive it or not they are all more clueless than myself. Thanks larry

You haven't looked far. There are smart wet-heads in Maine.

Hello Badger

There might be but not in Northern maine, from what I have seen. Even the plumbing distributer REDLAWN was conffused on what i wanted when my plumber ask them for prices. they said they have no idea what TRV valve was and what it was needed for.

I can ssure you i have looked far. I bulit a new house in 2009/2010 and I interviewed a lot of plumbers and it seemed to me that 99 percent of them are installers, they dont understand flow, heat loss or much else but they sure can "install" a system and the quality is very very good, But a very good qulity system that is designed wrong is still bad.

Thanks for your input. And i did hire the "best plumber" according to reviews and word of mouth for my house and since then I have spent a ton of money getting my hydronic radient heat system to work correctly.

feel free to read my other help posts on here, I have a 1000k sq foot house with an air exchanger set at 155 CFM with no back draft dmaper on it. that unit is way over size and for 4 years i was wondering why cold air was bellowing into the house when the exchanger was off. After I had enough with talking to many different plumbers/HVAC guys who were clueless I did some basic research and found out I need a back draft damper. I bought one installed it and that issue all set.
I need to also add that the instruction clearly sates to install on if in a cold climate,

These forums are incredible for information gathering and I hole hearlty trust what is beibng said on here as i do not see any underlying reason for ppl to not tell the truth.

I stand corrected. It is a sad state of affairs. Seems we a are spending a lot of money to educate people that end up without useful skills.
