What is medium temperature hot water boiler (mthw)?

There is a tradition of referring to boilers operating in the range 100°C – 120°ׄC as Medium Temperature Hot Water Boilers (MTHW). While carrying out research for this Guide, it was noted that legally speaking, hot water boilers are divided into only two categories, those where the limiter set point does not exceed 110°C, and those where it does.

What does lthw stand for?

This document applies to all industrial hot water boilers (normally shell boilers), including mobile hot water boilers and waste heat boilers, that fall into the following categories: • Low Temperature Hot Water boilers (LTHW): boilers where the shut-off temperature of the safety temperature limiter does not exceed 110 °C, with a design pressur…

What is the maximum temperature range for mthw systems?

The authors are aware that design standards may appear to contradict this opinion; EN 14394 for example allows for the limiter to be set as high as 120°C, but note that all such standards include additional requirements for plant with a limiter set above 110°C and we are therefore content that separate advice for MTHW systems is not needed.
