About electric patio heater running costs

Electric patio heaters can draw high power because they heat an outdoor area. Wind and open space make perceived warmth less efficient.

How to spend less: Heat a sheltered occupied area and switch the heater off when leaving.

What this estimate assumes

  • The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.

  • The rate is an approximate residential average in Washington. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
  • A month is 30 days and a year is 365 days.
