For the winter, you want your diffuser placed in water that is about 1/4 the total pond depth. That will open up the ice, let sunlight in, outgas the water, but still leave a warm water refuge for the fish.
There's more to aeration than pumping air into the pond. You need to calculate how many gallons per minute the diffusers bring to the surface, how many gallons of water are in the pond, etc., etc.
Find an electric calculator online and calculate your 5 hp motor running "X" minutes per month vs the smaller system. Remember when a compressor starts, it uses roughly 50% more juice than when it's running.
