Inquiry (采购产品): tankless unit not heating water water heater model h-36-6 purchased four years ago. installed over a year ago. stopped heating up the water about an hour ago. the only light working is the on switch. both lights are off and do not light with the flow of cold water as a faucet is being turned on. i am suprised that we are having problems with this unit as we have only been using it full time since november 1908 when we finally moved in. i am having surgery next week and built a handicap shower so i could have the ability to take showers. help thanks jean seaquist **** Hidden Message ***** jean seaquist p.o.box 35 309 broad street mason, TX 76856 0035 USA Company: seaquist inc.
