If I leave them on (1500 watts each) the engineroom is 70 in a few hours in zero weather. Having them on the Cubes keeps the engineroom about 40 and protects the generators and plumbing. Although since I live aboard, I've never measured below 34 in zero weather w/o heat in the engineroom.

You mean this? I have a funny story about mine.... It was in the engine room plugged in when I bought the boat, and a few weeks after, I needed to plug something in down there.

I was scratching my head trying to figure out why the AC outlet wasn't working, flipping breakers, and eventually just unplugged what I thought was an odd thing to have in the engine room - a splitter on an outlet that likely does not get much use.

It wasn't until a couple months afterwards that I realized it was a temp controlled Thermo Cube

I think I'd want one with a slightly higher temp level for my setup. But I have one
