This is an excellent, informative video. Your products appear to be excellent as well. Thank you.

I want to replace the ancient cast iron supply lines running to my cast iron radiators. I'll be checking you guys out for sure.

Hi Bob - Love the videos. I've watched a bunch and I've learned a lot from this channel over the past few weeks. I have a question - I'm currently renovating a home in Europe and we had a floor heating system installed. We have two manifolds in separate areas of the house, and I've noticed that in both cases the water send is going through the bottom of the manifolds where the actuators are located, and the return comes back through the top where the flow meters are located. The guy who installed it seems to think the opposite is true (that the send is on the top and the return is on the bottom), however I've taken meticulous pictures of the entire renovation and I can plainly see he is wrong. I'm curious what I can expect if the system comes online with this setup (it's not running just yet). A lot of people here are telling me it's not a big deal, it will work. I've read online it will work but the flow meters will not work. Any help would be greatly appreciated.

I have the 668...S1 manifold system with 41 circuits.
Most of the flow meter indicators are problematic. 
Some of them are stack to the zero indication, and some of them are stack to the maximum indication. They are not moving at all.
Is there a way to fix them in order to balance my underfloor heating?

Hello! Where can I find the temperature indicator shown in your video at 11:13? I am interested about its data sheet, but also to buy it. Thanks in advance.

I forgot to say that the underfloor heating was installed in 2010 but it was used for the first time in November 2012.

installing these upside down also seems to reduce the reliability of the flow meters....

Any chance of a clip-on thermometer for 3/4" pex?
