No , It should not feel hot if it is not pumping . and watch out for the artis pump..mine sprung a major leak at 3 weeks old and had it replaced with a sure-flo.brand.
Just for fun , lift up the sofa next time the furnace is on to cool area and see if pump works. maybe you need some venting there?
It was a rainy few days at Algonquin Prov park...tarps kept us dry.
