re: Workshop hydration

My shop usually doesn’t get uncomfortably hot even on the hottest days unless I’ve been running my shop vac (two 1000W motors). A couple of years ago we bought a heat pump for the house. It works real well and it’s very economical to run, but it was not nearly as quiet running as the more expensive ones. The noise it makes (higher pitched than I can hear) drives my wife nuts, so we have decided to buy a better more quiet unit before winter and we plan to install the ‘old’ one in my shop. So better shop heating in winter and air conditioning in summer even
with the vac on.
