LTHW stands for Low-Temperature Hot Water, a type of heating system that uses water at lower temperatures than traditional heating systems, typically around 60°C to 93°C. These systems are known for being more energy-efficient and suitable for various applications, including residential and commercial buildings. 

Here's a more detailed breakdown:

What is LTHW?

• Reduced Heat Loss:

  Lower operating temperatures minimize heat loss during distribution, improving overall system efficiency.

• Versatile Applications:

  LTHW systems are widely used in residential buildings, schools, offices, and other settings where standard space heating is needed. 

• Low Temperature:

  LTHW systems operate at lower water temperatures, often between 60°C and 93°C (or 140°F to 200°F).

• Efficient Heat Transfer:

  The lower temperature still allows for efficient heat transfer through radiators, pipes, or underfloor heating systems.

How does it work?

• 1. Boiler/Heat Source:

  A boiler or other heat source heats the water to a lower temperature compared to traditional systems.

• 2. Distribution:

  The heated water is circulated through a network of pipes or other heat transfer devices (radiators, underfloor heating).

• 3. Heat Emission:

  The water releases heat as it circulates through the system, warming the space.

• 4. Return:

  The cooled water returns to the boiler to be reheated, completing the cycle. 

Benefits of LTHW Systems:

• Energy Efficiency: Lower operating temperatures reduce energy consumption compared to high-temperature systems.

• Cost Savings: Lower energy consumption translates to reduced heating costs.

• Environmental Impact: Lower energy use contributes to a smaller carbon footprint.

• Individualized Heat Control: LTHW systems can be designed to allow for individual heat control in different areas of a building.
