You might be okay using Radiantec to assist you with heating a small addition or area but I would never try to do a whole house. There is too much at risk and too many complications. Search radiantec and you will find stories of real disasters. Check out heatinghelp.com, some of the regulars there have come across some messes from people that have installed systems as instructed by Radiantec.

Thanks funnycide. Based on information learned at heatinghelp.com it sound like the method they sell can be unhealthy. I will be looking to hire a pro. Thanks!

Hello,
This is like any other project. Buy the correct tools to do the job. Buy extra materials so that you can afford to screwup somewhere. Plan for problems with leaks and allow pipe to be shifted. The process is a continuous pipe loop. The joints are the only issue. Don't staple thru the pipe and you will be ok. Plan to insulate underneath. In the past, connections are most of the problems. Every joint can leak.

As I see the process, it is 95% affixing the metal plate with pipe to the underside of the floor and later insulating. You probably need a box of drill bits, and a 90 degree angle drill.

Back in 2012 I built my home and installed radiant under floor heating from Radiantec. This is the system that I put in the direct system. The tubing layout, system, and heating calculations were all approved by the city planning commission before I started so I knew that everything met code and was designed the right way.

The system works great and other than some general maintenance, I've had no issues. I did almost all of the work myself except for the installation of the water heater. The tech I worked with (can't remember his name) was very knowledgeable and held my hand through the entire process. Very happy.

Installed a whole house system in my Portland OR two storey Craftsman. Everything worked fine for the first 15 years. Eventually, the 7/8" pipe system fittings started to fail. Back then, they pushed a coupling and fitting system that is basically barbed fittings with SS hose clamps. Just this morning, I noticed a dripping sound in the crawl space. Pulled back the insulation and discovered two of the couplings are leaking at a good clip. Looks like I'll be replacing them with the new compression fittings they sell. Buyer beware! I won't support this company because they won't accept responsibility for their very flawed fittings that have proven to be time bombs just waiting to fail and cause considerable damage to your home.

Portland Oregon are as well (here) and have been looking at Radiantec. Question for user Wendi Siri from Portland...You installed a system 15 years ago with the parts/fittings they supplied at that time...Are they still supplying those same parts you see fail in your instance or have they possibly upgraded them for the better during the 15 year time span?

Installed my system in 2000 for a whole house remodel. I used their thin-walled pipe and connection hardware. Many connection failures due to poor design. They have since changed all their couplings and fittings to a compression style fitting that appears to be more robust. Radiantec has some good systems, but I would not recommend using their open-direct system that uses the Polaris water heater or their thin-walled tubing. Stick to Uponor's tubing and hardware. It is way more robust and has been used in many more radiant systems.
