Since the installation of the new hot water heating system, every attempt has been made to minimize the input temperature to the perimeter heating line in an effort to condense and minimize gas consumption. As it is not possible to achieve this desired condensation during most of the winter, this is of course an ill fated measure.

When this happens, the heating load is shifted to the Enercon units, so electrical costs are increased as a result. Any attempted saving of natural gas cost, is far exceeded by a direct increase in electrical costs incurred with the unnessary use of the Enercon units.

This is very evident when temperatures drop to current levels. This is certainly not an acceptable way to operate our heating system. The input temperature on the perimeter heating line must be increased to a level of 190 degrees (F) or more when necessary. Supply of heat from the Enercons is only necessary with prolonged cold extremes in temperature.

It has been suggested that the caretaker and management refuse to use a temperature setting above 175 (F) degrees, as they are afraid that a higher temperature will cause the perimeter lines to leak. The perimeter lines, zone valves and other fittings on these lines are generally rated at 250 (F) degrees and 150 PSI pressure rating, both well beyond what our system can possibly reach. Zone valves and expansion joints on these lines have not been properly inspected for a very long time and are only looked at after they have failed and begin to leak.

The fear of leakage as a result of minimal and deferred maintenance is not an acceptable reason for keeping the boiler temperature far below where it should be.

Yes, it is time to turn up the heat!
