WHEN THE GAS COMPANY technicians came to restore service immediately after the termite fumigation, they noticed that the water heater in the school building was not working properly: its burner jets were producing luminous yellow flames. They said that for them to relight the water heater’s pilot light would be unsafe, and therefore against company policy. So they slapped on red tags instead.

Happily, on the next work day a plumber came to diagnose the problem. The prognosis: after 24 years of faithful service, our water heater had reached the end of its useful life. Repairing it would cost almost as much as replacing it.
As I write this, the water heater is being replaced with a far more efficient unit. According to my previous calculations, the new unit should use almost half as much energy to heat the water that our building needs. (By law, new units are more energy efficient than they were 24 years ago; and the new 30-gal tank better fits our limited hot water use than the previous 50-gal tank.) Which means that it will mostly pay for itself if it lasts for its predicted lifetime.
