Reliable Heating and Cooling for Every Project

LPHW Heating Systems for Efficient Commercial and Industrial Spaces

Meta description: Discover cost-effective LPHW heating systems and industrial heating and cooling units for reliable performance in commercial buildings.

Mark Climate Technology delivers advanced LPHW heating systems and industrial heating and cooling units that combine performance, efficiency, and durability. Designed for installers and building owners, our solutions provide comfortable indoor climates while reducing energy consumption.

Whether you manage a warehouse, factory, or office building, our LTHW heating technology ensures dependable temperature control in every season. By using warm water from a central boiler or heat pump, these systems create space heating without the high emissions of traditional fuels.

What is LPHW Heating?

LPHW stands for Low Pressure Hot Water. In an LPHW heating system, water is heated to a moderate temperature and distributed through pipes to unit heaters or wall unit heaters. This method offers:

  • Even distribution of warm air
  • Compatibility with multiple heat sources, including renewable options
  • Lower operating pressure for improved safety
  • Reduced heat loss compared to older systems

If you’re wondering what is LPHW heating in practical terms — it’s a proven, cost-effective way to deliver heating and cooling in commercial and industrial buildings.

How an LTHW Heating System Works

An LTHW heating system (Low Temperature Hot Water) uses water at lower temperatures, making it ideal for use with modern heat pumps. The process:

  1. Heat is generated by a heat source such as a gas boiler, biomass boiler, or air-to-water heat pump.
  2. Warm water flows through a water system to LTHW unit heaters or fan coils.
  3. A built-in fan distributes heated air evenly throughout the space.
  4. The water cools slightly, returns to the boiler or heat pump, and the cycle repeats.

Our industrial unit heaters are designed for long-term reliability, even in demanding environments.

Types of Water Supplied Air Heating Systems

LPHW Unit Heaters

These LPHW heaters use warm water to generate airflow. They are ideal for construction sites, warehouses, and workshops, where rugged design and high airflow are essential.

LTHW Unit Heaters

LTHW unit heaters run at lower water temperatures, making them perfect for integration with renewable heating systems such as heat pumps. They improve efficiency and reduce carbon emissions.

Wall Unit Heaters

For smaller areas or targeted heating, wall unit heaters provide compact performance without consuming floor space. They are well-suited for offices, retail spaces, and workshops.

Indirect Fired Heaters

Indirect fired heaters use a heat exchanger to separate combustion gases from the airflow. This makes them safe for applications where air quality is critical.

Benefits for Installers and Building Owners

Choosing Mark Climate Technology means benefiting from:

  • Industry leading product quality and service
  • Compatibility with existing water systems and heat exchange setups
  • Easy installation and low maintenance
  • Flexible mounting options to fit every space
  • Proven reliability in industrial heating units and commercial buildings

Our designs are engineered for efficiency, helping you reduce running costs while meeting environmental goals.

Applications

Our commercial unit heaters and industrial heating units are used in:

  • Warehouses and logistics centers
  • Manufacturing facilities and workshops
  • Sports halls and public buildings
