I have a hot oil radiator I use in the office at work--works great by itself, but when a park a fan behind it at low speed, it does an outstanding job of heating the whole office.
It's 70 here now :-). Der Prinz and Der Son have gone for their 14-mile run, and I think I'll take the little boys for a stroll around the block.
It will give Wednesday an opportunity to come downstairs and eat!
This is just a little two-speed fan heater that cost $12. I've had it on low speed, and it has a thermostat in it so it doesn't burn itself out. But it's been working for the last almost two months as my principle heater.
The complex sent in a maintenance man, and all he did was run my furnace for an hour, telling me it would "warm up soon." It never did. So I just shut it off. The next tenant can worry about it.
