The formula that you enter in a cell remains visible in the formula bar, and you can see it whenever that cell is selected. Show you are a real person * Choose a glazing type or alternatively enter the u-value if known. A general rule of thumb would be to say 80C onto the radiator and 60C off the radiator, giving an average temperature on the radiator .
