I have a climatemaster 6 ton water to water unit for our 3500 sq foot home. When it was first put in 5 years ago we didn't have a storage tank. (First time installer) So the compressor would trip the circuit breaker about once a month because of too much load. Also our electricity costs werereally high, because the compressor would run every time heat was called for. So, last year another company added a 120gallon storage tank. But I feel that they may have plumbed it wrong. The way it is plumbed now is the storage tank has two outlets on the bottom of the tank and one at the top. The bottom outlets have water to the compressor out of one, water to the house out of the other, and the outlet from the compressor and the return from the house go into the top of the tank. Is this correct? I would think that the hottest water should be at the top of the tank, and should go to the house, and the outlet to the compressor should come out of the bottom and the two inflows should go into the other bottom. I would appreciate any links for correct diagrams, or input.
