My second purchase of a RMB-1.
By The Lodge
from North East Alabama
Comments about Radiant Mixing Block:
One RMB-1 in garage 6 years ago tied to a LP tankless HW. Keeps garage temperature at setting. Second RMB-1 is being installed in main house. Note- You may want to remove the check valve on the boiler input. At certain flow rates it will buzz and sound like a motor bearing is bad. PexSupply.com the name says it all at a good price.
Bottom Line Yes, I would recommend this to a friend

Expensive- use the K.I.S.S. Principle
from Allentown, PA
I added radiant heat and I thought this was my answer to control temperatures/boilers more efficiently. I wound up using this as a simple "setpoint" setup. Very similar to an ordinary "mix valve". When it works it is very good. However, upon some power interuptions I have to reset the unit or the injectionpump locks at minimum giving me 70 degree heating water instead of the requested 130 degree water. Taco is no help and blames my setup ignoring the fact that it works some of the time. If I had to do this again, I would use a simple mix valve. No need for the complicated electronics here. Use the K.I.S.S. principle.
Bottom Line No, I would not recommend this to a friend

Dollars & Sense - the only way to go!
from Windsor CT
I purchased two RMB's for my system. One was for use in my newly installed radiant heat system (addition) and the second was installed on my older existing cast iron radiator system.The new radiant heating system can now be controlled to perfection. The older system is much more efficient and we no longer have "spikes" in the heating cycle. We are also protected from shocking the boiler with a surge of cold water into the return.While the RMB's can be expensive, I am now heating a larger area for a lesser cost and doing it much more efficiently with the same(existing) boiler!
