I don't think thats ok... I was always told that any temp under 75 can cause health issues for BP's. I'd be curious to know what someone with more experiance has to say about that though.
I have one of these in my room to keep ambient temps up at night. My house temp drops down to about 50 degrees at night and it keeps my 12' x 12' room at 68 degrees on the low setting.
Seems like 50 bucks would solve your problem either way.![]()
