: what would cause a tankless coil not to produce hot water after about5 mins.? boiler water maintains 180 degrees. but after about 5 mins.domestic hot water turns cold.

there are a couple reasons this may happen
(1) tankless coil walls are becoming built up with minerals from the water causing poor heat transfer
(2) tempering valve is defective
(3) you are overdrawing the coil meaning you are using more hot water than can be produced by your coil.
this problem can be resolved but is not soething that cvan be fixed by a homeowner consult a qualified plumber
