What cage do you have? You shouldn't need a second emitter unless the cage is huge. Usually all that is needed is to enclose the sides and back of the cage to help hold the heat in. The heavy clear plastic sold at Fabricland works great and you can either use binder clips or clothespins to attach it.

To reach the bathroom you shouldn't need two extension cords. Just get a more heavy duty longer cord. They come up to 100' long.

 

It shouldn't blow a fuse as the power bar is in one of the sockets and there is still the other socket. I put 2 power bars in the dual sockets and completely fill them as I have a 125g aquarium running in my livingroom with 2 filters, 2 lights, and 2 heaters on one power bar and then my TV, home theatre, satellite and lamp on another power bar so adding another power bar to add a CHE should be fine. But like Nancy pointed out you can always put something on the side to keep the heat in better and then you shouldn't have to get a 2nd CHE.

 

Also, what wattage CHE are you using? They come in different strengths, if your clamp can handle it perhaps you can just increase the bulb.

 

I have a "super pet my first home extra large" cage. The back is covered by a thermal blanket, but the cage was only getting up to 73 the other night, before I turned the heat on, and that was with the CHE running constantly.

As for CHE bulb wattage, I have a 150. I think my lamp can handle up to 250, so I'll look into that.

 

I know you said it would take two extension cords to get to the bathroom, but what about purchasing a long and thick one? You have your standard 'brown' style extension cords for household use but there are also 'contractor extension cord' which are heavy duty, doesn't have a triple outlet end on it but you can get them up to 50 feet, you get a 10 or 12 gauge one (thickness of the wires inside) so it wouldn't be overloading the cord itself, just means you'd have a big extension cord running through the house.

Try covering the back and both ends. Using clear plastic holds the heat in but still allows light to enter the cage.

Do you have the emitter sitting right on top of the cage or angled in towards the cage?

A 150 emitter should be enough.

I'll try covering the sides and back. The emitter is right on top of the cage. Oddly enough, it's been fine the past few nights without the heat in the house on. Very odd. I'll keep monitoring it and decide if I need a more powerful bulb.
