horizontal hot water cylinder - can't be right | DIYnot Forums

horizontal cylinders are a complete waste of space, essentially because you have very poor stratification due to the height of the cylinder. Add to that problem, I bet there is little or no baffle on the cold water inlet so the whole tank is being sloshed around giving you the 'tepid' results.

A Complete Piping Analysis With Thermal Stratification

The thermal stratification condition typically will cause pipe to bow in on a long horizontal segment. These conditions have not been commonly considered in piping design. However, the additional thermal cyclic stresses and loads due to these conditions could lead to the fatigue damage of the piping components and the failures of pipe supports.

stress classification and FSRF for thermal stratification

I'd like to hear your opinion on classification of repeated thermal stratification for fatigue assessment using the smooth bar curve. Hot/cold liquid stratification, or a half-filled horizontal cylinder can cause both thermal bowing and localized thermal stress at the level where an abrupt temperature transition occurs.

Solar Energy - Renewables Industry News

The operation of de-stratification dramatically reduces the effectiveness and efficiency of a solar system's heat input capacity fitted to that cylinder. The boiler is also heating a much larger volume of water than it would be subjected to if stratification was allowed to occur.

Thermal stratification within the water tank - ScienceDirect

Thermal stratification within the tank can be achieved by several methods : (1) heating of vertical walls which results in the creation of hot thermal boundary layers drawing hot fluid into the upper part of the tank; (2) heat exchange between the fluid contained in the tank and that circulating in a heat exchanger carefully placed inside or outside the tank; (3) direct inlet into the tank of hot fluid at suitable heights.

stratification in horizontal tanks | Hearth.com Forums Home

I am curious as to how well stratification develops in horizontal tanks. Anyone have a well instrumented set up who can relate their experience? I am looking to use 2 500 gal tanks side by side, plumbed in parallel, with a two pipe arrangement to feed floors and the tanks from the boiler at the same time if demanded.

Small Stainless Steel Chilled Water Buffer Tanks | Buffer

These hydronic buffer tanks are also perfect for use as a wood boiler buffer tank. The Chiltrix heavily insulated small chilled water / hot water / boiler buffer tanks are tall and thin so they are perfect for thermal stratification as well as applications where a small floor footprint is required (18.5: diameter).
