Q1: Is there an island in the middle of the bath? Does the cord go down through the middle of the pedestal?

A: There is a slight hump in the middle (not technically an island), under which the heating element is located. The cord extends up through the base of the pedestal and safely tucks away out of sight on the basin's underside.

Q2: How many watts is the heater? What temperature will this keep the water to?

A: This heater is 150 watts. The heater turns on automatically when the water temperature is 43 degrees or lower and will automatically shut off at 60 degrees and stay off until 43 degrees and repeats the cycle.

Q3: How much water does this birdbath hold?

A: This model birdbath holds 1 to 1.5 gallons of water.

Q4: Is this birdbath heavy enough to withstand a wind storm?

A:

No, this birdbath is not heavy enough to withstand a wind storm.

Q5: How does it hold strong winds?

A: You need to put stones or sand on the base so it can hold up to strong winds.

Q6: What temperature can this unit handle? Would it get damaged with lower temperatures?

A: This unit can handle -20 degrees Fahrenheit.  It shouldn't get damaged, but the water would freeze, so it is recommended to dump the water when the temperatures start to get that low.
