I have a two story home and i use a Newport oil fired boiler, tankless, My problem is i cannot get any heat on the upper floor, the bottom floor no problem,The thermostat sparks blue when i turn it up upstairs,yet no heat .The thermostat downstairs runs fine ,now i try to turn it up as high as possible to heat upstairs ,but really then can not stand to be downstairs. Ihave gone and bleed all baseboards and still nothing,It;s really cold here in Maine right now so please help,just had boiler cleaned 1 month ago 130.00,Really can;t afford to pay out more,got to girls that are cold. Thank;s for any help can get.
