Size of Heater

[SeanB.]

We are installing a 15x34 fibergl*** IG. It is about 17000 gallons. What size heater do we need? Will 200K BTU do the trick? Is there value in "bigger is better"?

Thanks-

Jeff

Ours will be just over 13,000 gallons and they are putting in a 250,000 btu heater, if that helps - not sure how they determined what size to use though.
