They look like original radiators from the Victorian era but deliver moden heating efficiency. Heat Transfer by Convection of a Heat Sink with Fins Calculator and Equations Fins are used to increase heat transfer area and provide a cooling effect. P = perimeter of the fins. To figure out the floor area, multiply the floor length by its width. Find out more in Radiator Valves Explained. Something like the Bonaire white double vertical flat panel radiator 1600 x 456 (pictured below) would be ideal. 38.4cm (15.1) x 32.2cm (12.6) x 3.3cm (1.3) = 249ci Then I used the above equation: add 0.2 for a medium trailer towing add 0.2 for outside temperatures of 105F (40.5C) add 0.3 for no fan shroud add 0.3 for air conditioning (not fitted in UK but possibly abroad) Mr Central Heating's BTU Calculator can help you calculate the BTU (energy) requirement of your room. Radiator sizes differ vastly depending on the style and variety of radiator you decide to opt for.

The process is sometimes referred to as a Powerflush and costs 300 600 on average. 1 Room Type Choose your room type. Add on 10% to account for heat loss. Always use a Gas Safe registered engineer. The second consideration to take into account is the the heat loss from your room. If cooking, the kitchen area is likely to be warmer so you may also wish to have slightly more heat output in the dining area. Being sure to make the correct BTU calculation is very important. A rooms BTU requirement is based upon the cubic volume of the space the height, length and the width of the room multiplied by four (done for you by our calculator) and what is above, below and besides the room. Just to clarify Im not developing a calculator for general use. Standard doesnt mean one-size at Stelrad and the options are limitless!

Over time air bubbles can build up which means the hot water can't fill the radiator; with less surface area for the heat to emit from the radiator won't heat the room as well.
