seem to recall u need a separate line for the 240.but i will defer top the experts. --208.58.x.xx

I can tell you that the 120 volt towers heat a room nicely. I keep them on hand for when a tenant's heat goes out --208.94.xxx.xxx

I too like the 110 tower units. I keep them for emergencies also. --173.66.xx.xxx

For those lower priced places (under 50K) that get 500 approx. for rent, that's how I go. --72.135.xx.xxx

When I buy the MH, the first thing I have to do to pass city inspections is to add electric wall heaters in the living room and 3 bedrooms. I will do the sub-panel like you suggested with home-run wiring. --76.18.xxx.xxx

Most of the previous responses are wrong. The output of the heater is directly related to the wattage. A heater of given wattage operated at the design voltage produces the same amount of heat a any other heater of the same wattage, even if the design voltage of the other heater is different. Operating cost is the same for equal wattages, no matter the voltage. A 1200 watt heater for 120 volts draws 10 amperes. A 1200 watt heater for 240 volts draws 5 amperes. A 120 volt circuit with #14 wire can supply a 1440 watt heater. A 240 volt circuit with #14 wire can supply a heater of 2880 watts. The reason for my numbers is that circuits supplying continuous loads must be loaded not more than 80% of the full circuit capacity. Heater loads meet the definition of continuous which in the NEC is 3 or more hours without interruption. --67.213.xx.xx

These electric heaters are installed recessed inside the wall between two studs that are 16 inches on center. They are the least expensive heating system for a house that I know of. I use them in my low end rentals where Central H/A is not economically feasible. --76.18.xxx.xxx

I have struggled with the heating/cooling questions. Central HVAC is expensive even with me buying at internet prices and doing the install myself. The cooling is easy to get around with cheap window units being both plentiful and reasonably efficient. However, electric strip heat is very costly to operator. Even though electric heat is almost 100% ENERGY efficient, it is VERY financially inefficient. SSOOO, my question to Roy and others who use electric heat in rentals, do you have tenants who have trouble paying the rent because the heat bills are so high? Do your tenants complain about high heat bills with the electric heat? --199.248.xxx.xx

I would check the box and see if they give an efficiency value for both the 120 and the 240VAC. A watt is a watt is a watt; however, how much input power is required to produce the specified output heat? --70.239.xxx.xxx

In fact, with the new lead laws I have been considering a plan to build a few NEW SMALL rentals. I call them Jerry Cottages. As I consider the specs, one of them will be no wire smaller than #12. The NEC will probably get there at some point anyway. --199.248.xxx.xx

ROY if you get TVA power you have some of the best electrical rates in the country and should take advantage of it. --70.250.xxx.xxx

Trying again to create an understanding. One watt = 3.14 BTU. That's it, as simply as it can be expressed. --67.213.xx.xx

I can tell you in CA in my all electric gold medallion 4 unit that has radiant heating in the ceiling and thick popcorn on the ceilings inside surface that it's expensive to heat the units with this electric heat. Dumb dumb dumb planning. This was a Statewide construction building project in 1964-65. So it was government backed by grants. --24.176.xxx.xx

Typing error on my previous post. One watt=3.412 BTU. --67.213.xx.xx

I just hardwire baseboard heaters for my mobiles. I do run new wire to the panel. --71.98.xxx.xxx

A more efficient way of electric heating is to install radiant floor electric heating which will be expensive to install. Basically it is the voltage times the current. So if one is using 120 Vac times 6 amps then that is 720 watts. If one is using 240 VAC times 3 amps then that is 720 watts. If the existing heater is using a voltage then it is easier to replace with the same voltage which will avoid changing the wiring, thermostat and circuit breaker. A heat pump is more efficient as long as the temperature is above freezing. Another option is to upgrade windows, insulation and doors which will reduce the heat loss. As the heat loss is reduced then the amount of heat will be less. --74.220.xxx.xxx

240 is always better, if your going to be running new wire anyways it's no extra work. Just be careful, I've never been shocked by 240 but I heard it hurts. --66.228.xx.xx

Sounds interesting,I'm going to look into them. How much do they cost? Where do you buy them at? There is not much room in the wall of a mobile.I wonder if they will work on them. Most winters down here are mild until this past one. --71.98.xxx.xxx

--76.18.xxx.xxx

240 is the way to go with heaters and airconditioners. They will use less power compared to the 120. Higher the voltage, lower the amps. --12.161.xxx.xx

Thanks Roy, I'm going to check them out. --71.98.xxx.xxx

Take a hike Gypsy until you improve your knowledge. Your knowledge is worthless and could be considered 'dangerous' to some of the newbees. You are an insult to a landlords' knowledge. --187.52.xx.xxx
