During warmer months, heat from warm air is transferred to the heat exchanger and into the fluid. As it moves through the pipes, the heat is dispersed to the rocks, soil, and groundwater. The pump is reversed during the colder months. Heat energy stored in the relatively warm ground raises the temperature of the fluid. The fluid then transfers this energy to the heat pump, which warms the air inside the building.

By Eskridge Law. Last month's bulletin addressed the need to retain various employee records. Since we received a couple e-mails asking how long these records must be kept, we thought that would be a good topic for this month's bulletins. Naturally, there is no single answer.The length of time you must keep the records depends on the type of records involved.he FMLA requires the retention of certain records with respect to payroll and demographic information as well as information related to the individual employee's leave of absence for three years. : OSHA requires that records of job-related injuries and illnesses be kept for five years.
