Cold Water to BathRm, No hot. No water to kitchen,

We have everything skirted with 3 heaters underneath with a temp gauge. It's runs around 40 degrees underneath with all water hoses heat taped, including the ground water. Cold water is coming in, and hits the shower and sink and toilet first, then runs to the kitchen, I believe. This is where the problem occurs. No hot water is being pumped back to the bathroom area, and no water at all is being pumped to kitchen sink. Nothing is frozen and I can feel heat around the 10 gallon holding tank.
