Hi

i have a portable heat pump air conditioner which i am using to heat my house.
when its really cold it spends half the time switched off and defrosting.

i was wondering if the more expensive heat pumps have any advanced features for defrosting?
my heat pump just switches the compressor off to defrost and waits for the frost to melt.
do any heat pumps use water to defrost? or electric? or would that be heating the outdoors and poor efficiency?
