i will not trust anything inportent to a computer. heating is unimprtent, just add more jumpers! use soler to heat your water and youve asved a huge amount of mony, and co2 emisans

computerising everything just makes it dificult to service, witch meens you haft to get somone out, who will most lickly replace it. witch produces tuns of unsesesorry waste. for the same resen new cars are rubbish, carnt service it yourself. boring!!
