What is LTHW?

LTHW stands for Low Temperature Hot Water. It's a heating system that uses water heated to a relatively low temperature (typically below 80°C or 176°F) to distribute heat throughout a building. This is commonly used for space heating in residential and commercial buildings via radiators, underfloor heating, or fan coil units. It is a cost-effective and efficient way to heat buildings, and is often used in conjunction with renewable energy sources such as solar thermal collectors or heat pumps.
