Question

I know that my heat recovery ventilator consumes 83.2 Watts of power to run its fans when supplying balanced fresh air into my house. If it runs 24 hrs a day, how many kWh's of energy would it consume in a year?

Answer 1

Answer: 730 kWh

Explanation: To solve this problem we have to use the following considerations:

If teh heat recovery ventilator consumes 83.2 W running 24 hs we have a consumed energy of:

Energy consumed= 83.2* 24= 2 kWh

so in a year we must multiply by 365 then

Energy consumed in a year= 2kWh*365= 730 kWh
