Tankless hot water

Scott Brink_2

Being new to this whole steam heating, I was hoping one of the experts could help me a little in understanding how the hot water system works.

I have a one pipe steam system with a tankless hot water supply. Could you please give a little basic information on how the hot water system works, and how that effects the boiler/heating system.

Thanks.

Good info, but

There are some great pieces there with wonderful information. I just can't find one that talks about tankless hot water. Do you know of one?

tankless heater

The tankless, or coil, is just that. A tightly wound coil of copper tubing in immersed in the boiler water. An aquastat will keep the boiler hot enough to generate domestic hot water out of the coil. It is then sent through a mixing valve to temper the water to desired and safe temperature levels. The flow of cold water is usually "choked down" to a level where the coil can produce adaquate amounts of hot water. Generally, but dependent on pressure and pipe sizing and the like, flow is restricted to the coils maximum capacity (IE: 3 1/2 GPM). The mixing or tempering valve is especially needed when the boiler is running to generate steam. The difference between boiler water temp and exiting domestic hot water can be as little as 15-20*, so a 212* boiler will generate around 180* water at the coil. Most plumbing codes restrict hot water temps at 120* max. Hope this helps you.
