'Rubbish In -> Rubbish Out' is a well accepted fact in the world of simulation. Regardless of the technical capabilities of your thermal simulation tool, the accuracy of prediction will always be tightly coupled to the accuracy of the input data. The most accurate thermal  IC package model is a so called 'detailed' model where all the internal construction is represented … [Read more...]

It would only have cost me an extra £170, a small extra compared to the cost of the rest of the build, but I decided against laying thermal insulation boards directly under the underfloor electric heating mats. Surely better to leak some of the heat down to heat the 100mm thick concrete screed which would maintain its heat through those cold winter weeks, giving thermal support … [Read more...]
