3/8" PEX is common for small radiant heating projects, since it's the most flexible oxygen barrier PEX size. Areas of the house such as kitchens and bathrooms require the smallest possible floor elevation and maximum heat distribution, since tile and ceramics are good heat conductors.
Because the OD of the 3/8" barrier PEX is 1/2", and it is the thinnest out of all oxygen barrier PEX sizes, installing it would mean a thinner slab and a minimum floor elevation.
