We have been looking at various radiant floor heating solutions for our existing home and are very interested in using Radiantec's solution. Has anyone ever used them and if so, can you tell me if you are satisfied with your solution?

They also offer a Solar option, which would heat the water for the radiant flooring. Anyone done this? I'm not sure if we will be allowed to do this since we live in Massachusetts and you can't use one heat source for both domestic hot water and heat. But if the law changes, we may consider adding the solar option.

Thank you in advance!
