    Need to know BTU of heat loss

    Thanks for the great replies! I understand what you are saying and perhaps I am using the wrong term for what I am looking for. If my 5200 BTU/hr heater is stabilizing the room temperature at 70F then the heat loss is 5200 BTU/HR. But if I want the stabilizeed temperature to be 75F I will need...

    Need to know BTU of heat loss

    Lets look at these senarios. 1. I place a 5200 BTU/HR heater in a room and it is only able to raise the room temperature by 0F. 2. I place a 5200 BTU/HR heater in a room and it is only able to raise the room temperature by 5F. 3. I place a 5200 BTU/HR heater in a room and it is only able to...

    Need to know BTU of heat loss

    This is a special project I am working on. The problem is I have a known 5200 BTU/hr heater in a room, the ambient temperature started at 65F, after a period of time the room ambient stabilized at 70F. The heater was only able to raise the room ambient by 5F, how many BTU/hr heat loss do I have?

    Need to know BTU of heat loss

    I am thinking it is a differential equation. When the room stabilizes the BTU/hr is equalized, BTU heat = BTU cooling which I understand. But if the 5200 BTU heater can only raise the air temperature by 5F rather than by 15F the heat losses must be greater and that is what I am trying to...

    Need to know BTU of heat loss

    Thanks for the replies! I see you use the 70 and 80 in the equation for the room stabilized temperature at 70, If my starting temperature is the same and the stabilizing temperatures are different then the btu/hr heat loss would be greater at 70F than at 80F correct? Here are two senarios...

    Need to know BTU of heat loss

    I need to know the BTU of heat loss I have in a room based on the following. I have an 800 cu.ft. room with a 5200 btu heater operating. The room temperature started at 65F and over a period of time the room temperature stabilized at 80F. How many BTU of heat loss do I have? What would be the...
