Hot water baseboard question

DV Member Posts: 2
I am remodeling my upstairs bathroom. The heating zone consists of a bedroom, bathroom and a bedroom. The pipe size in the baseboard is 3/4". The new baseboard that I would like to install in the bathroom is aluminum but it only comes with 1/2" pipe. My question is can I install a 5' section of 1/2" pipe heater element in my bathroom? The final installation would be 3/4" in the first bedroom then reduced down to 1/2" in the bathroom then pipe would tie back into 3/4" pipe in the second bedroom. Will this work? Thanks VIT

    It will work if you have less than twenty-five feet of BB in the second bedroom.
    8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

    Two btu per sq ft for degree difference for a slab
