Vented vs Unvented Hot Water Cylinders | Boiler Guide

The water travels down from the tank via a feed pipe to the bottom of the hot water cylinder. As the water is heated it expands, but the presence of the vent pipe and tank in the loft provides an escape route for the excess. This excess water travels through the vent pipe and back into the cold water storage tank in the loft. The vent pipe will

How to run a hot-water zone off a steam boiler

Jun 18, 2014 · The boiler water flows through the tank. Q: Does the hot water radiation have to be lower than the steam boiler's water line? A: No. If you're using a heat exchanger, your compression tank will keep the system under pressure. The fill pressure and tank size determine how high you can place the radiation above the boiler's water line.

Fire-tube boiler - Wikipedia

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank

Amtrol No. 30 Expansion Tank for Hydronic/Boiler-EX-30

This is the job of the expansion tank. In the old days plumbers would use a tank set up very similar to the overflow set up for a cars radiator. However this system would often allow air to be dragged back into the closed loop system when the water cooled. This air would cause corrosion. By using the diaphragm style tank this problem is eliminated.
