You can’t afford to skip this step. The PEX is cheap and you can add the remaining components later. I insulated around my foundation and under the floor. I heat a 1250 square foot building with a small on demand water heater. I doubt I have much over $1500 in the entire heating system including the PEX.
I agree. Also check your insurance rates with a radiant heat floor versus a wood stove. Be honest with your insurance agent. If you're not honest, they can deny anyclaim you might have. JMO.
