ERV – did I find a good buy or make a mistake?
My house plan is a simple, 1900 square foot ranch.
I purchased a Broan ERV, model 140 today. I could not turn down the price of $1187.75, shipped, tax-free. I thought this deal was “HUGE”, spoken in my best Donald Trump voice.
However, I must admit that I did not do my homework on this unit before making the impulse buy.
I just felt it was a grat price and knew it would do the job per the numbers. So, using the formula here, 7.5 cfm per person plus 3 cfm per 100 square feet , I arrive at (7.5*2)+(3*19) = 72CFM.
I am able to configure this unit to operate at a minimum air change speed of 85 CFM and max of 140CFM. I can also configure from 65–>140CFM but I wouldn’t be hitting my minimum 72CFM
Can anyone inject a measure of feedback for me about this unit? Good? Bad? Ugly?
