Our recommendation for replacing mechanical thermostats.
Digital thermostats are accurate to one degree.
The built-in timing mechanisms adjsut temperature settings at various times of the day and week, reducing household temperatures when you're not at home and during sleeping periods when most of us are more comfortable. Fuel savings can be realized even at room temperature settings because the digital devices are so precise. Probably the least expensive, yet most efficient change we can make in your plumbing system. Bathing with this tyhpe of shower head is just as satisfying, but far more efficient, than the older models. You'll realize substantial savings on your domestic water heating bill.
