Just got off the phone with stc valve aaking them if my coil is 3watts version, well they told me that 3w are only offered in 12v or 24v option. So im going there tomorrow to exchange mine. Alan are you sure your is 110v 3watts ? because if its regular 6.5w and its still does't get hot that i might stay with what i have and be done with it.
