| I sure hope you insulated under that slab and provided a thermal break between the slab and the walls. If not you are going to be sorry.
I'll answer your questions to the best of my ability.
1. The temperature of the circulating water is going to be dependent upon what you use for the finished floor. Carpet will require a higher temperature than will ceramic tile and wood will likely be somewhere in between the others. The slab will have a much slower response than will the Warmboard. You do not want the finished floor to be much more than 80 to 85 degrees F. or you won't be able to stand on it for more than a minute or two. Generally circulating water temperatures of less than 100 degrees F. for the Warmboard and maybe as high as 110 degrees F. for the slab depending on how well the slab is insulated.
2. Yes.
3. I don't have the necessary information on the boilers. Others on this board will be able to help here.
4. DIY install will probably result in no warranty. |
