Blast,
i wouldnt say it is a bad system some people just prefer to'feel' the heat coming from rads/heaters. The time taken to heat a house depends on the thickness of the screeds, it could take up to day to heat the house from scratch, which would be feck all good if you are away for the weekends or on holidays.
As for the heat output from geo thermal, there have been many reports where the system could not give the required output so the system had to be supplemented by another, which would completely defeat the purpose of installing it.
