Tom. Yup someone makes a pellet / log stove combination. Think it fires up the pellets to light the logs, then if store needs topping up and no more logs pellets kick in. You could d it with separate appliances and some controls but very expensive.
Don't think pellet supply will be an issue, too many appliances out there now.
CPL sold their oil side to concentrate on pellets! calor I believe have invested heavily in pellets too
