Anyone know anything about them? Our utility room has the fittings for one but don't know anything about the pros and cons (google not being v helpful). Have never owned td before but with ds2 and unpredictable weather it may be time to get one though I only anticipate needing to use it in the summer for underwear (heating isn't on but not warm enough inside to dry clothes before they get smelly and too much washing to do to leave it). Thanks
