I built a 3 story house in Erie, PA. The 1st floor garage is 10" block. I have installed a heated tubing system in the concrete garage floor and in the two stories above it. The house is right on the lake, it is 50' deep by 20' wide. I pumped the 1st 20' of the block towards the lake with concrete and rebar since the lake can actually hit the house in a really bad storm (maybe once a year). The rest of the block does not have concrete or insulation in it.

Since my floor is heated, I want to make sure I don't waste energy through the block. This is where I am getting several opinions and can't seem to find an answer on R-values.

Some friends suggest I drill holes and pump insulation into the block without insulation. Some say that I should put up 2x4 walls along the outside, insulate them and then drywall or plywood.

Can anyone tell me what the R-value of 10" block filled with concrete, vs. 10" block filled with blown insulation? Clearly the 2x4 walls with R16 would be great - but also more money and if water ever comes in, the damage would be greater.

Any advice would be greatly appreciated.
