hello, i have a hot water furnace that heats my tap water and house, and
i replaced my heater covers with heavy duty polypropylene soffit, now i
did some research, the furnace water never goes above 160F, the water
registers never go above 100F, and the soffit is rated not to distort
until a temp above *. ever since i installed them, the home made soffit
covers only get warm,never hot no matter how long the furnace is
running, My question is, would this pass for a safe cover untill i can
afford store bought * thank you..
