How much electricity does roof heat tape use?

Typical heat tape burns electricity at six to nine watts per foot per hour. That means each 100 feet of heat tape operating 24/7 can translate to an added monthly cost of $41 to $62 to operate heat tape, says Eileen Wysocki, energy auditor for Holy Cross Energy.

How much does it cost to run a heat tape?

If the tape is 6 feet long, it will use 30 watts when heating the pipe. To run this tape for one day, a homeowner would use 0.72 kilowatt-hours (kWh), which would cost 14 cents at $0.20/kWh (approximately the current rate in Fairbanks), or approximately $20 for four months.

How much electric does a heat tape use?

Energy Consumption

On average, heat tape consumes nine (9) watts per lineal foot.

Do heat cables use a lot of electricity?

As the heat cable warms, the cable adjusts the power usage to limit or regulate the actual temperature or heat output of the cable. … A typical constant wattage cable might use 5 watts per foot no matter what the temperature is outside. So, if the cable is 100 feet long, it will use 500 watts per hour.

Can you leave heat tape plugged in?

When the temperature drops, a small thermostat (built in on most models) calls for power that produces heat, then cuts off power after the temperature rises. You can leave these models plugged in. … The Consumer Product Safety Commission (CPSC) says they no longer collect data on heat tape-related accidents.

When should heat tape be turned on?

The roof heat cables should be warm to start melting immediately when snow is falling. In fact, they should be installed on your pipes long before the first freeze. The new self-regulated heat tapes will turn on when the temperature gets below 40 to 38 degrees.

Can you plug heat tape into an extension cord?

Do not use an extension cord. The heat tape must plug directly into a Ground Fault Circuit Interrupter (GFCI) receptacle. You should find a GFCI protected outlet underneath your manufactured home, near the water inlet.

  • Silicone rubber heat tapes are a good heat tape for applications up to 450°F, and are chemical- and moisture-resistant. ( …
  • Fiberglass-insulated heat tapes come without controls – no built-in thermostat.

Are Heating cables safe?

Today’s heating cables are safe, energy-efficient solutions to taking off winter’s chill. Heating cables are commonly referred to as heat trace cables, heat tracing, or heat tape, while the most advanced cable design, self-regulating heating cables, are also known as self-limiting cables.

Does heat tape need a dedicated circuit?

It needs GFCI protection if installed on a non-dedicated circuit. GFPE is necessary if the circuit is dedicated for heat trace and the receptacle is not readily accessible.
