Izifudumezi ezifunxayo zisetyenziselwa ukufudumeza iimveliso ngaphakathi kwitanki zokugcina, ngakumbi xa ezi mveliso ziqinile okanye ziqinile ngokulinganayo kumaqondo obushushu aphantsi.
Izifudumezi zokufunxa, ezenzelwe ngokukodwa ukufudumeza imathiriyeli kuphela xa zirhoxiswa, zonga iindleko zamandla amakhulu njengoko iimfuno zokufudumeza zizonke zicuthwe kakhulu.Izifudumezi ze-WNH zokuntywila zisebenza kufutshane ne-100% yempumelelo ngelixa i-oyile yamandla kunye ne-water-glycol thermal fluid systems zifumana ukusebenza okuphezulu, ngakumbi kumaqondo obushushu aphakamileyo ixesha elide.Iisistim zolwelo olushushu zingasetyenziswa ngokudityaniswa nezitshintshi zobushushu ezintywiliselwayo ukunika isisombululo sokufudumeza itanki kwisityalo esibanzi.Ngamava angaphezulu kweminyaka eli-10, iinjineli ze-WNH zinokukukhokela kwinkqubo yokumisela eyona nkqubo inexabiso eliphezulu kakhulu kwisicelo sakho.
