This post relates to boiler, tankless heaters and hot water heaters, and my main question is whether what I want to do is allowed so I posted it in the plumbing forum - I hope that's right.
I have a steam boiler with a hot water coil, a gas h/w heater and a tankless water heater. I want to set them up so that I use the tankless in the summer and the boiler coil/gas hot water heater in the winter.
The gas hot water heater will be piped so that the cold supply goes into the boiler coil. The boiler coil out will go to a mixing valve, then to the cold inlet of the gas hot water heater.
Is this legal? I'm wondering if it is because the boiler coil and gas hot water heater loop will be stagnant in the summer. It shouldn't be a problem as long as they are drained each summer (and the tankless in the winter) but I'm not sure this set up is permitted by code.
Thanks
