Demand is the rate at which you use energy. If you have a bucket and begin to fill it with water, the amount of water in the bucket is the amount of energy (kWh, kilowatt hours) you are billed for and the rate the water goes into the bucket is demand (kW, kilowatts).
How do utilities charge for demand?
Each utility is different but demand is usually charged using the highest 15, 30, or 60 minute average. This means that if you have your air conditioning, water heater, dryer, dishwasher, pool pump, spa heater, and steam shower running on at the same time each family member is watching a different television while drying their hair with a hair dryer and the double oven is baking a turkey and apple crisp while each burner of the 6 burner stove is cooking a different dish, you are going to be using energy very rapidly and have a high demand.
Can you explain On Peak and Off Peak?
It costs utilities different amounts to generate and transmit power at various times throughout the day. Utilities have power plants that are designed to run constantly and supply power continuously. At peak times utilities have to generate power using plants designed to run only during those peak times when the extra power is needed. Some utilities charge different amounts for energy and demand during these peak times instead of charging an average rate 24 hours per day.
What does a Dencor Demand Management System do?
The Dencor system monitors the amount of power you are using and calculates your demand. The system has sophisticated algorithms which control the major appliances and systems in your home to reduce demand while ensuring a comfortable environment and plenty of hot water. A Dencor system acts as an orchestra conductor, making sure the air conditioning, water heater, dryer, dishwasher, pool pump, spa heater, and other loads run as needed but they don't all run at once.
My clothes dryer turns on and tumbles but does not heat up. Is my dryer broken?
No, your dryer is functioning properly. We often receive this question from someone who has moved into a home with a Dencor system that was configured for the previous owner. Some Dencor system owners choose to set the system so the dryer will not dry during the on peak period. This is not required and is a choice they have made. If the system is programmed this way the dryer will tumble but will not provide heat. A simple change in the programming of the Dencor system will fix this issue.
What systems and appliances does the Dencor system typically control?
Every system is configured to your needs so there is no such thing as typical. Some people put a higher priority on savings so those systems may prevent the dryer from heating during the on peak time when power is most expensive. Others, although they want to save money, will put a higher priority on convenience so during the on peak time, only the pool pump may be prevented from running. The Dencor demand management system usually manages the air conditioning, clothes dryer, water heater, pool pump, and spa heater although your system may control other appliances based on your needs. Inside the front cover of the system is a list of items and how they are controlled. Referencing that chart will provide you with specifics on how your system is configured.
