Hi,
Watts don't care what type of heater they are powering--and they are all the same total heat. However, radiant heaters warm what they are pointed at first--and then the heat from the warmed object radiates to the room.
Wrong. Those same watts powering a heat pump will put out almost twice the BTU's of heat than the best radiant heater. Radiant heat is not very efficient when compared to other methods of producing heat. Here is a link. Heat pump See if you can find ANY radiant heater that can put out 9500 btu's of heat, and blow it throughout the coach with only 950 watts/8.18 amps.
1500 watts of radiant heat will generate ONLY 5200 btu's of heat.
If you need the maximum amount of heat for the minimum amount of wattage, use a heat pump. If you have plenty of power available and are concerned about cost, use the radiant heaters.
Yes, but a heat pump doesn't actually create heat... well, except for what the motors inside it create.
You are right but if you remove the cold from the room, you are left with the heat. The cold is blown outside. Stand under one of the roof top AC/heat pump units and with 15,000 BTU's of heat, drawing only 12 amps, you would swear that it is heat blowing on you, and so would the thermostat as the coach gets warmer. :B
Naturally the roof top units will quit in the 30's but the portable unit, that I gave the link on, has warmed our coach even with outside temps in the lower teens.
