 The Shocking Facts About Sudden Thermal
Changes
|
| |
When a modern hot water boiler
experiences thermal shock, the cause is often ignored and written off as defective
material or workmanship. But there is always a reason why a boiler (cast iron, steel fire
tube or steel water tube) becomes thermally shocked. "Boiler Thermal Shock" can
be loosely defined as sudden thermal changes that occur within the boiler causing rapid
and uneven contractions of the boiler's cast iron or steel material. We explore the causes
of thermal shock, the influence of system design and ways to prevent thermal shock here. |
M&M’s New WFE Unimatch Water Feeder for Steam Boilers
|
| |
McDonnell and
Miller introduces the new Uni-Match Universal Water Feeder.Automatic Water Feeders offer the homeowner the convenience of
maintaining a safe water level in steam boilers - automatically. When the water feeder
receives a signal from the low water cut-off, it feeds water into the boiler, protecting
the boiler from dry-fire conditions. McDonnell & Miller’s new Uni-Match Universal
Water Feeders work with any mechanical or electronic low water cut-off and features
adjustable dwell/feed cycles to tailor performance to specific system dynamics.
The Uni-Match also has a hard-stop feed limit to minimize the chances of overfilling the boiler.

BE GREEN - Energy Saving Variable Speed Applications with Small Circulators |
| |
Variable Speed pumping has several applications that can save energy costs and prevent thermal
shock in boilers or snow melt applications. The VS controller can be
used in domestic heating and cooling applications, primary-secondary applications and injection
pump applications.
Bell & Gossett’s Variable Speed Controller has internal controls, is able to be controlled externally
with 4-20mA or 2-10V signal and can improve system efficiency and comfort.
