Reduce energy losses and improve system efficiency with effective insulation of hot and cold water pipes

Since hot or cold water travels a fairly long distance throughout a building, it is crucial that it maintains the required temperature as much as possible. During this process, the water passes through many areas where additional heating or cooling is unavailable, which can cause uninsulated pipes to heat up or cool down — leading to various negative consequences.

To keep water hot or cold, pipes require different levels of performance:

Hot water — insulation prevents heat loss and maintains temperature when water is transported from a boiler or heating system to central heating units.
Cold water — insulation maintains a low temperature and ensures water is delivered at the required temperature.
Rain/waste water — insulation of cold water pipes prevents water from heating up.

In every case, effective insulation allows HVAC systems to consume less energy to maintain the operating temperature of equipment, thereby reducing energy consumption.

Why is pipe insulation necessary?

Heating and cooling systems in buildings account for approximately half of total energy consumption. Reducing energy demand helps decrease operating costs and carbon emissions — especially in large facilities such as airports, residential complexes, warehouses, and schools.

HVAC pipe insulation improves the operating efficiency of heating and cooling units and ensures comfortable temperatures with minimal energy usage.

The fire-resistant properties of our stone wool insulation are also important — especially for hot pipes — as they can run throughout the building at high temperatures.

Acoustic absorption reduces the impact of noise from pipes and HVAC systems on people inside the building, minimizing daily discomfort.

Calculation and savings

Applying insulation for cold pipes can provide energy savings of up to 50%, while insulation for hot pipes can deliver savings of up to 20%. Differences may exist between countries, but overall, pipe insulation offers a return on investment within 3 years.

Our pipe products with aluminum facing and aluminum laminate facing are designed for hot and cold sections respectively. Both are available in medium density (up to 100 kg/m³).

Insulation thickness is determined based on:

• The operating temperature range of the HVAC unit

• The average temperature of the piping or air duct

• Additional parameters considered in calculations (Legionella prevention or increased energy performance)

• Environmental conditions (humidity % and temperature °C)
