Flow through heater mk2 FTH2 both side displayed

FTH Ⅱ

FTH Ⅱ is an ultra fast high pressure (20bar) water flow through heater based on a thick film heating element. Water runs at high speed along a channel over the heater. This results in hot water in just seconds. FTH Ⅱ delivers water up to boiling temperature and can even create steam! The heater will vastly improve the sustainablity of your application. This is confirmed by this LCA, conducted by TNO.
