What does it cost to run?
Tank heaters, waterers, block heaters and pumps run more than you think. See what each one costs a month, and where the easy savings are.
Block heater timer
A diesel only needs 2 to 3 hours of heat before you start it, not all night.
An outdoor-rated timer usually pays for itself in the first month.
VFD on the vacuum pump
A variable-speed drive slows the pump down when it doesn't need full vacuum.
Studies often show it cuts the pump's power use by about half. Power company rebates can help pay for it. Grants & rebates →
Waterers
Insulated waterers on a thermostat use far less than an open tank with a de-icer running flat out.
Check them every fall. A bad element or thermostat can run nonstop, or put voltage in the water so cows quit drinking.
The math
Watts × hours a day × how many ÷ 1,000 = kWh a day.
Multiply by 30.4 days and your rate to get the monthly cost.
Costs are estimates from the numbers you enter. Your actual bill depends on your rate plan, demand charges and the weather.
