At 60,000 BTU, a 5 ton water-source heat pump is the largest size — used for big zones and commercial spaces on a well-designed water loop. Conditioning this much from a single unit puts the spotlight squarely on loop design: flow, temperature, and heat rejection all have to keep up.

A 5 ton unit places a heavy demand on the loop — it needs substantial water flow and moves a lot of heat in and out. That means the loop piping, pump capacity, and heat rejection (cooling tower or ground field) have to be sized deliberately for it, and in a multi-unit building a few 5 ton units can dominate the loop's total load. Get the loop design right and the unit runs at the high, stable efficiency water-source systems are known for.

Large zones and commercial spaces on a water loop — the largest standard size, moving 60,000 BTU of heating or cooling from a single indoor unit.
Substantial water flow and enough heat-rejection capacity (cooling tower or ground field). The pumps and piping must be sized for the flow, and it's a large share of a building loop's total demand.
Yes. At the largest size, the loop's flow, temperature, and heat rejection directly cap performance, so deliberate loop design is what lets the unit deliver its rated capacity and efficiency.
With a well-designed loop, very — the stable water temperatures give high, consistent EER/COP year-round, avoiding the weather-driven efficiency swings of air-source equipment.
