Browse our range. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. BTUs are British Thermal Units, the unit in which radiator efficiency is measured. What temperature do you recommend using for the winter design temperature? Where the calculator is used for the heat losses in a new extension, then the pull down menus also offer u-values for current Building Regulations. The heat transfer area can be calculated after values have been determined or estimated for the required heat transfer rate, Q; the overall heat transfer coefficient, U, and the log mean temperature difference for the heat exchanger, Tlm, based on the values of several input parameters. Thanks units). This article was co-authored by wikiHow Staff. Q: What t does the calculator assume for the heating system and radiators. Room Info. Hi I am trying to calculate the BTU for a old loft bedroom probably done when the house was built in the 1800s. Choose a glazing type or alternatively enter the u-value if known. Is there an official document like SAP 2012 version 9.92 (October 2013) that lists room wise ACH values? For example, a room requiring 2000 BTUs could have 1 large vertical radiator (producing 2000 BTUs), or you could have 2 small horizontal radiators (each producing 1000 BTUs) to make a total of 2000 BTUs. Radiator sizes are not consistent over different models, due to their varying dimensions. As the room is not square more a prism shape, how do I calculate its BTU? The larger your room, the more BTUs your room will require in order to be heated sufficiently. Do beware of using purely theoretical calculations as the average space heating demand of a new building is often double or more the SAP design calculations, for a variety of reasons. With this information and a bit of mathematical prowess - we can then determine the expected heat loss for your room and provide you with a BTU output to heat the space efficiently by which we mean to a comfortable temperature and at the lowest possible fuel costs to you. https://www.deals4homes.co.uk/video/calculating-a-Uvalue.html Scroll to the bottom of the page to find out more about using the calculator. What is above the ceiling (another room or the roof)? To calculate the British Thermal Unit (BTU) output accurately and effectively for a room, you will need to grab your tape measure.
