Replacing a steam heating and hot water network with a Low Pressure Hot Water (LPHW) system can offer several benefits, making it an attractive option for many buildings, especially older ones with outdated steam systems. The reasons for such a replacement typically include:

Energy Efficiency

LPHW systems are generally more energy-efficient than steam systems. They can operate at lower temperatures while still effectively heating a space, which reduces energy consumption and costs.

Improved Control

Hot water systems allow for better control of heating, as they can be easily zoned and regulated with thermostats. This means individual rooms or areas can be heated to different temperatures based on occupancy and use, which is more challenging with steam systems.

Reduced Maintenance and Operational Costs

Steam systems, especially older ones, can require more maintenance due to the complexities and age of the components. Hot water systems, on the other hand, tend to have lower maintenance requirements and associated costs.


Steam systems operate at higher pressures and temperatures, which can increase the risk of burns and other injuries from leaks or faults. Hot water systems, with their lower pressures and temperatures, are generally considered safer.

Space Efficiency

 Steam pipes are typically larger than those needed for hot water systems, so converting to LPHW can free up space within a building. This can be particularly beneficial in retrofit projects where space is at a premium.


LPHW systems can provide a more consistent and comfortable heat distribution compared to steam heating, which can sometimes lead to overheating and uneven temperatures in different parts of a building.


For buildings undergoing renovations, converting to a LPHW system can be part of a broader modernisation effort, updating the infrastructure to meet current standards and expectations for comfort, efficiency, and sustainability.

Environmental Considerations

Given the push towards greener and more sustainable building operations, the improved efficiency and lower carbon footprint associated with LPHW systems can also be a significant motivating factor for conversion.


Each building and heating system is unique, so the decision to convert from steam to hot water will depend on a variety of factors, including the age and condition of the existing system, renovation plans, budgetary constraints, and specific heating needs.
