A failing commercial hot water system can disrupt operations, frustrate staff and customers, and pose compliance risks. Whether you manage an office block, retail premises, school, care home or industrial unit, reliable hot water is essential.
Alliance CFM provides professional commercial hot water system replacement for businesses across Reading and the surrounding areas. Our experienced engineers design, supply and install efficient systems tailored to your building’s size, demand and regulatory requirements.
If your system is unreliable, inefficient or beyond repair, we can help you upgrade safely and with minimal disruption.
When Does a Commercial Hot Water System Need Replacing
Many businesses search for signs a commercial hot water system needs replacing. The most common indicators include:
- Repeated breakdowns or costly repairs
- Insufficient hot water during peak demand
- Rising energy consumption
- Inconsistent water temperatures
- Leaks from cylinders or storage tanks
- Ageing plant room equipment
- Obsolete parts that are no longer supported
Commercial systems often work far harder than domestic boilers. Once performance declines, replacement is often more cost effective than continued repairs.
Types of Commercial Hot Water Systems We Replace
Every building has different requirements. We replace and upgrade a wide range of systems including:
Commercial Boilers with Hot Water Cylinders
Traditional plant room setups using commercial boilers connected to large storage cylinders. These are common in schools, offices and residential blocks.
Direct and Indirect Hot Water Cylinders
For properties using separate heating systems, we replace both direct electric cylinders and indirect systems linked to boilers.
Unvented Commercial Cylinders
These systems provide strong, consistent pressure across multiple outlets. Replacement must be carried out by qualified engineers to ensure compliance and safety.
Gas Water Heaters
Common in restaurants, leisure facilities and industrial buildings. We upgrade inefficient or undersized units to modern high-output systems.
Electric Commercial Water Heaters
Suitable for smaller commercial premises or buildings without gas supply. We assess load requirements to ensure adequate performance.
Commercial Hot Water System Replacement Process
Businesses often ask how long commercial hot water replacement takes and whether operations will be disrupted. Our structured process ensures minimal downtime.
Site Survey and Load Assessment
We assess current usage, peak demand, pipework layout and plant room configuration. This ensures the new system is correctly sized and future proofed.
System Design and Specification
We recommend a system that matches your operational requirements. Oversizing wastes energy, while undersizing causes performance issues. Correct design is critical.
Safe Removal of Existing Equipment
Old boilers, cylinders and associated components are safely isolated and removed in accordance with gas and water regulations.
Installation and Integration
We install the new system, upgrade controls where necessary and ensure compatibility with existing heating infrastructure.
Commissioning and Testing
The system is pressure tested, balanced and fully commissioned. We verify performance under demand conditions.
Handover and Maintenance Advice
We provide guidance on controls, servicing schedules and compliance requirements.
Alliance CFM ensures compliance with:
- Gas Safe regulations
- Building Regulations
- Water Supply Regulations
- Legionella control guidance
- Manufacturer installation standards
For landlords and facilities managers, compliance is not optional. Proper installation and documentation protect your business and occupants.

How Long Does Commercial Hot Water System Replacement Take
Timeframes vary depending on system size and complexity. Smaller systems in light commercial settings may be completed within a short timeframe. Larger plant rooms or multi-cylinder systems require more planning and staged installation. We plan works carefully to minimise disruption and can schedule installations outside normal operating hours where required.
