Smart Hot Water is PAS 2025/2030 Compliant

February 21, 2025

 
With decarbonisation and energy efficiency at the core of the retrofitting agenda, social housing providers and retrofit coordinators are facing increasing pressure to meet stringent standards while delivering long-term value. The good news? Smart technology is proving to be a game-changer, particularly in the realm of hot water systems. 

Yet, some retrofit projects hesitate to embrace these solutions, often due to misconceptions about their compliance with PAS 2035/2030 standards. Let’s set the record straight: smart hot water systems, such as those from Mixergy, not only meet PAS 2035/2030 requirements but also provide a compelling path forward for efficient and sustainable retrofitting projects. 

What Are Smart Hot Water Products? 

 
When we say “smart,” we’re not just talking about modern tech for the sake of it. Smart hot water products are internet-connected systems designed to optimise energy use, provide valuable data insights, and enhance overall efficiency. These systems communicate about their operation, environment, and usage patterns, offering significant benefits over traditional setups. 

Key examples include: 

  • Smart Hot Water Controls – Intelligent control systems that manage heating and water usage efficiently. 
  • Smart Hot Water Cylinders – Advanced storage systems that adapt to usage patterns to minimise energy waste.

Clearing Misconceptions: PAS 2035/2030 Compliance Confirmed 

Some retrofit coordinators have been hesitant to approve smart hot water products, believing they fall outside PAS 2030 standards. However, a closer look at the standards proves otherwise. PAS 2030 Annex C specifically addresses requirements for hot water controls (Measure BSM.5) and hot water systems (Measure BSM.6), which include both traditional and smart variants. 

Smart Controls for Hot Water Systems 

  • Installation Compliance: Smart hot water controls align with PAS 2030 Annex C, Measure BSM.5, which covers heating, hot water, air conditioning, and ventilation controls.
  • Vocational Competence: PAS 2030 references the Scottish Skill Matrix, which includes a dedicated category for smart heating controls. 
  • Compatibility: Whether traditional or internet-connected, all relevant PAS 2030 guidance applies equally, ensuring smooth integration into retrofit projects. 

Smart Hot Water Cylinders 

  • Installation Compliance: Annex C, Measure BSM.6, explicitly details installation requirements for hot water cylinders, including smart alternatives. 
  • Exclusions Clarified: Only cylinders with integrated heat pumps require additional compliance under MCS standards.
  • Proof of Compliance: Mixergy’s MDC0001-16 Mixergy X Cylinder and Mixergy Cube X-DHW align fully with PAS 2030 Annex C guidelines.

Why Smart Hot Water Systems Belong in Retrofit Projects 

Integrating smart hot water solutions into retrofit projects isn’t just about meeting standards—it’s about maximising efficiency, cost savings, and environmental impact. 

  1. Improved Energy Efficiency: Smart hot water systems reduce energy waste by learning usage patterns and heating only what’s needed. Mixergy’s smart cylinders, for example, can cut energy consumption by up to 20% compared to conventional systems. 
  2.  Data-Driven Decision Making: These systems provide real-time performance insights, helping housing providers optimise energy use, predict maintenance needs, and reduce overall operational costs. 
  3. Supporting Decarbonisation Goals: By seamlessly integrating with renewable energy sources like solar PV and heat pumps, smart hot water systems support the transition to low-carbon housing, aligning with Social Housing Decarbonisation Fund (SHDF) objectives. 
  4. Enhancing Tenant Experience: Smart systems empower tenants with greater control over their hot water usage through intuitive apps, leading to lower bills and improved comfort.

Moving the Industry Forward 

For retrofit coordinators and social housing providers striving to balance compliance, cost-effectiveness, and innovation, Mixergy’s smart hot water controls and cylinders offer a forward-thinking solution. Not only do they comply with PAS 2035/2030, but they also represent the future of energy-efficient retrofitting. 

This isn’t just about ticking compliance boxes—it’s about driving real progress towards a more sustainable, efficient, and tenant-friendly housing sector. Smart hot water is here, and it’s time to make it a standard part of every retrofit project.
