Controlling Humidity in the Winter

[Brent]

I have a 1 bay SS car wash in Manitoba Canada. The weather is very cold in the winter. I have electric in floor heat and and an electric duct heater (make up air unit) that runs when the humidity gets to a certain set point and the exhaust fan kicks in. My issue is I keep the humidistat set fairly high 70% so the exhaust fan doesn't run too long and pull in a lot of cold air in a cold air does not carry humid air out very well.

Questions:
1) What do people try to keep there humidity at in the winter?
2) Does anyone use and HRV to help control humidity as well?
3) What other things can a person do to try and be energy efficient in the cold months. (Natural Gas is not an option).
4) Is there something obvious I am missing?

Thanks!
Brent

How much do you charge per minute to use this 1 SS bay?

Normally when it gets real cold the humidity drops way down. I think your humidistat is bad. Can't imagine 70% humidity in below freezing weather. And if it is that high, what's the problem?

$1 for min 20. It has an outdoor bay as well but closed in the winter, small community.

This morning the humidity is 13%, extremely cold -31C. We are closed. When it warms up a bit and a a customer is washing this is when the humidity spikes. It is hard to exhaust warm humid air into the frigid cold. This is my issue.

$1.00 for 1 min 20 sec. Have an outdoor bay for the summer as well.
