No what heals are best for party healing (as holy)
Your holy word (single target) is your most mana efficient heal, keep it on CD on the tank. Have enough haste (12.5%) to have renew5 (5 ticks of renew per cast). Then just stay in single target chalk and drop heals on the tank while weaving in holy word AND gheal as needed.
For party damage. CoH heals for more then PoH, but distance limitations come into play. So be careful. Binding heal is very handy in large damage scenarios binding heal tank, then PoH with serenity is quite the boost.
