Piper Hydro Inc. of Irvine said its previously announced preliminary agreement to provide a $684,000 solar and gas-powered heating system for a 228-unit Las Vegas apartment complex is conditioned on completion of long-term financing or a sale of the system to a third-party investor. Additionally, the company said, funds from the sale will be shared equally with Piper Hydro’s joint venture partner, MCS Inc. of Las Vegas. The preliminary agreement was signed with Spear Development Co. of Las Vegas and a final agreement will not be completed until Spear approves design of the space and water-heating system.
