Modernising legacy heating systems

3 December 2025

Alpha commercial boilers help modernise legacy heating systems across the UK by replacing outdated plant with high-efficiency, low-emission and future-proof solutions.

Reliable, energy-efficient heating is essential for commercial buildings of every type – from schools and churches to civic facilities and leisure venues.

Recently, several very different organisations have chosen Alpha’s commercial boiler range to modernise their plant rooms, replacing their ageing, standard-efficiency boilers with modern condensing systems that offer greater performance, lower emissions, and reduced running costs.

Manor Primary School, Uckfield

Manor Primary School needed a dependable heating system to replace an outdated standard-efficiency boiler. The Alpha Ares Tec was selected for its compact footprint, modular design and excellent seasonal efficiency.

The new boiler provides consistent comfort for pupils and staff while helping the school reduce energy consumption and ongoing running costs.

Albany Baptist Church, Bexley

Albany Baptist Church required a responsive system capable of coping with varied occupancy patterns – from quiet weekdays to busy weekend services. Engineers installed two ProTec NX boilers, replacing the old standard-efficiency plant.

The cascade configuration allows each boiler to modulate independently, improving efficiency during low-demand periods while still offering the power needed during events and community gatherings.

Ilkley Town Hall, West Yorkshire

A civic building with a wide range of functions, Ilkley Town Hall needed a robust and efficient solution capable of supporting daily council operations and public events. Two Ares Tec 150kW boilers were installed, providing high output, excellent modulation and built-in redundancy.

The upgrade ensures reliable year-round performance while significantly improving the building’s energy profile.

Bingo Hall, Southend

For this busy leisure venue, uninterrupted comfort heating is a must. The existing system was replaced with two 150kW ProTec NX boilers, providing strong output capacity and the benefits of condensing efficiency.

The new setup reduces running costs and increases reliability – an important factor for a venue operating long hours with high footfall.

Delivering efficiency across diverse sectors

Although each building had different requirements, all shared the same objective: to replace outdated heating equipment with modern, efficient technology. These projects demonstrate how Alpha’s commercial boilers offer:

  • High efficiency and reduced carbon emissions
  • Flexible modulation for varying demand profiles
  • Simple integration into existing plant rooms
  • Increased reliability through multi-boiler cascades

These installations also provide a strong foundation for the future. The upgraded boiler systems are fully compatible with hybrid configurations, meaning heat pumps or other low-carbon technologies can be added later if the building’s requirements change.

From education and public buildings to leisure facilities and community spaces, Alpha continues to provide dependable heating solutions that support long-term performance and sustainability.
