style='font-size:10.0pt'>Yes, we spent many hours modelling radiant systems and
invested a great deal of finance. The results have been somewhat published in
papers by Gaw, Ruess, Holst and Simmonds, also Bjarne Olesen and Meirhans have
published work on active concrete. There are also other publications such as
Markus Kochenz. EMPA were Kochenz used to work has also published data on controlling
radiant floors. Night flushing has also been reported by Braun and Simmonds.<o:p></o:p></span></font></p>
