energy credit

[TAX4US]

Not sure: TP has water lines running at the bottom of his pond being circulated by a geo thermal heat pump for heating and cooling of house. During 2017 old pump quit. New high efficiency one cost 17k to install. Lines in pond ok just pump went out. Question is would this be one that qualifies for the 30% no cap limit credit? just a note TP told me his heating and cooling cost dropped nearly 70%.

Check sections 40401 and 50402 to see if the equipment is 30% or 10%??
