Embodied carbon is the total greenhouse gas emissions associated with a material, product, or construction throughout its lifecycle. Unlike operational carbon, which is emitted during a building’s use, embodied carbon is locked in from the start, making it a crucial factor in decarbonisation efforts.

It includes emissions from:

• Raw material extraction – Mining, quarrying, and harvesting resources
• Manufacturing and processing – Transforming raw materials into products
• Transportation – Moving materials and equipment to the site
• Installation & construction – Assembling products into buildings
• Maintenance & repair – Keeping systems operational over time
• Demolition & disposal – Managing waste and recycling materials at end-of-life

Embodied carbon plays a major role in reducing overall emissions in the built environment. Here’s why it’s important:

Unlike operational carbon, which accumulates over time, embodied carbon is released upfront. Reducing it from the design stage is crucial

In energy-efficient buildings, embodied carbon can exceed operational emissions.

As operational emissions decrease due to energy efficiency and renewable energy, embodied carbon becomes a larger share of total emissions.

Choosing the right materials and design approach is key to cutting embodied carbon in heating systems.

Embodied carbon is a critical factor in achieving net-zero goals. By focusing on material choices, efficient designs, and sustainable practices, we can lower carbon footprints and build a more sustainable future.

The best heat emitters for low water temperature systems are those that deliver full design output at the lower flow temperatures heat pumps and condensing boilers run most efficiently on. Low water temperature heat emitters from S & P Coil Products Limited (SPC) include fan convectors with enhanced or low flow coils, radiant panels, unit heaters and trench heating, alongside bespoke heating and cooling coils. SPC is a British manufacturer based in Leicester, with over 50 years of experience and ISO 9001:2015 certification. Talk to our team about your project.

Lower water temperatures help heat pumps and condensing boilers work efficiently, but they also reduce the output of a traditional emitter. Heat pump systems typically operate at around 45 to 50°C, and at these temperatures natural convection falls away, which is why fan-assisted emitters and larger heat exchange surfaces are often specified. The emitter is part of the efficiency strategy, not an afterthought.

For design guidance on heat pumps in commercial buildings, see CIBSE AM17: Heat pump installations for large non-domestic buildings. For wider context, read our post on embracing a low-carbon heating future.

As temperatures drop across the UK, HVAC systems are at risk of serious damage. In areas where temperatures have reached as low as -10°C, frozen water inside HVAC coils can expand, causing cracks, splits, and potentially catastrophic system failures.

When water inside HVAC coils freezes, it expands, creating pressure that can cause the coil to crack or split. This is a common issue during freezing weather but one that can be prevented with the right precautions.

To avoid burst coils and costly repairs, take these steps to protect your system:
1. Ensure your heating system is operational and circulating warm water to prevent freezing
2. Drain unused coils to avoid stagnant water, which is more likely to freeze
3. Check insulation and lagging for vulnerable areas that could allow cold air to reach the coils

Antifreeze or glycol solutions can be used to protect your coils from freezing. However, glycol should be considered as a last resort, as it can have a negative effect on coil performance and fluid pressure drop. Always ensure the correct percentage of antifreeze or glycol is used to maintain system efficiency.

At SPC, we design and manufacture heating and cooling coils built to perform in extreme conditions. Our team offers:
1. On-site surveys to assess coil damage and identify issues before they become critical
2. Custom replacement coils designed to fit your system, ensuring minimal disruption
3. Faster lead times than many other UK manufacturers, helping you get back up and running quickly

The risk of burst coils is real, but with the right precautions, you can prevent damage and avoid costly repairs. If your coils have burst or you’re concerned about your system’s performance this winter, contact SPC for expert advice and solutions.
