What size electric baseboard heater do I need?

Question

The room is about 10x13 and I have electric baseboard heat, just pulled a 6 footer out or there looking to replace it with a newer one. IS this the size I need for that area? Also, looking to go with a hydronic baseboard, I heard they are much more efficient, is that true? Thanks

More Info: house is located in CT, 2 outside walls, 2 double-pane low-e windows, walls are insulated: don't know the rating....Above the room is an attic, below it is a garage. Thanks!

Answer 1

How did the old 6 footer work? If it worked, put in the same size. A larger unit may require upgrading the wiring. Oil filled coils will work better when the heat is on constantly. Non oil works best when the unit is turned up and down or on and off frequently. The efficiency and cost to run is the same with either one.

Answer 2

First of all, the only way to determine the size heater required is by a load calculation. That requires more information than just room size. Also, hydronic baseboards are not more efficient. Any electric heater is 100% efficient at converting the electricity to heat. For more info about all that and more, check out my source.

Answer 3

Yes they are .. as for size you need more info;
outside walls?
climate
windows?
Exterior doors?
Heated or unheated space above?
Insulation?
Put that info together and take it to (or call) your local electrical supply and they will do a quick "Heat loss survey"and tell you (and sell you) exactly what you need.
Or post again here.
Good Luck.
You should need roughly 15-1700 watts...6' is roughly 1200 watts so by my estimate 8' or 9'(a 6' and a3') would be better if you have the amperage. otherwise a 6' will defiantly take the chill out just insulate if needed.
stay warm.

Answer 4

Did it work before you pulled it out? You could replace it it an 8'. Do you have forced hot water already? If so then tieing into an existing one should be easy
