What we'll cover...
An investment in a new radiator, electric heating product or heated towel rail is an important decision, and one that will usually draw a few key questions prior to purchase. You might want to know how the product has been tested, what standards or certifications it meets, how it is decided to be fit for sale, and what happens if a product doesn’t perform up to expectations.
In this guide, we’ll tackle each of those questions and more, explaining how products are chosen to join the BestHeating collection, which testing processes they undergo before sale, what certifications they must meet, and how customer feedback helps to shape future product selection and development. Each process outlined in the article is based on confirmed procedures managed by our quality team and buying specialists.
How we choose what we sell at BestHeating
Long before a product is made available to buy on the BestHeating website, it undergoes a detailed evaluation process.
Our dedicated buying team reviews every potential addition to the collection against a series of strict criteria designed to deliver quality, performance, safety and long-term durability and reliability.
Products are assessed on a range of criteria, including:
- Build quality and material specification
- Heat output in relation to size and intended room type
- Manufacturing consistency and procedures
- Finish quality and color accuracy
- Compliance with relevant key certifications and safety standards
- Supplier reliability and quality assurance processes
- Lead times and supply-chain performance
- Packaging durability and potential risk of transit damage
Heat output is an especially important aspect of the BestHeating product procurement process. Whilst we prioritise beautiful aesthetics, a radiator isn’t judged solely on appearance; it must also deliver the expected performance for its size and intended application. This is why we recommend customers make use of our BTU Calculator when selecting a new radiator, helping to ensure the right balance between looks and heating performance.
It’s also possible that products are rejected at this stage. Much like with the approval process, there’s a few standout principles that our buying team will focus on to arrive at the correct decision.
A product or supplier may not be approved if there are concerns surrounding:
- Poor or inconsistent build quality and material concerns
- Failure to meet expected performance benchmarks
- Non-compliance with safety standards
- Uncompetitive pricing with relation to product quality
- High defect rates during sample assessment
- Unreliable communication or supply-chain problems
Put simply, products must demonstrate quality, consistency and reliability before they are considered fit for inclusion in the reputable BestHeating range.
How every product is tested before sale at BestHeating
Product testing is one of the very most important parts of the quality assurance process before sale.
Every radiator sold by BestHeating undergoes a series of factory-level inspections and performance tests before it is approved for sale and made available to buy online.
Each radiator is subjected to pressure testing to 10 bar, flow testing, thread inspections, paint adhesion testing and finish and coating quality checks.
Mark Wignall, Quality & Environment Manager at BestHeating
Each of these tests serve a specific purpose to ensure the premium quality look and performance levels that customers have come to expect from BestHeating.
Pressure testing to 10 bar
Every radiator is pressure-tested to 10 bar to verify system integrity and confirm it can safely withstand operating conditions.
For homeowners, this provides peace of mind and confidence that the radiator has been checked for leaks, weaknesses and manufacturing defects before leaving the factory.
Flow testing
Flow testing is done to verify that water circulates properly throughout the radiator.
This helps confirm that internal waterways are functioning as intended and allows the radiator to deliver its stated heat output performance.
Thread inspection
Radiator connections are inspected carefully to make sure that all inlet and outlet threads meet specification.
This reduces the risk of installation issues and helps ensure compatibility with valves and pipework.
Paint adhesion testing
The durability of a radiator finish is equally as important as its appearance.
Paint adhesion testing confirms that coatings bond correctly to the radiator surface, helping minimise the risk of flaking or premature deterioration over the course of time and usage.
Finish and coating inspections
All radiators are visually assessed to ensure that color consistency, surface quality and finish standards align with specification requirements.
This is particularly vital for specialist finishes such as anthracite, metallic and designer color options, where consistency plays a major role in the final appearance.
Additional inspections after arrival
Quality control doesn’t stop once products leave the factory.
Products also undergo further inspections after arrival to ensure they look and perform as expected before being made available for sale.
The BestHeating Quality & Environment team note that it is rare to identify issues during these latter-stage inspections due to the rigorously thorough nature of factory testing procedures. However, the additional checks provide an extra level of reassurance before products reach our customers.
The standards and certifications BestHeating products meet
Independent certification plays a crucial role in verifying product performance and safety.
BS EN 442 Certification
All BestHeating designer radiator ranges are independently certified to BS EN 442 standards by a notified body.
This is the recognised European standard for radiators and covers:
- Thermal performance
- Heat output verification
- Energy efficiency measurements
- Structural safety
- Reaction-to-fire behaviour
Practically speaking, BS EN 442 certification refers to published heat outputs and performance figures having been independently assessed as opposed to simple manufacturer estimates.
For homeowners comparing radiator sizes and outputs, this provides valuable confidence that the figures they’re using are reliable and accurate.
ISO 9001:2015 Registered Manufacturing
Milano products, which make up a large proportion of BestHeating’s radiator offering, are manufactured under ISO 9001:2015 quality management standards.
ISO 9001 is an internationally recognised certification which focuses on quality management systems, continuous improvement and process consistency.
In simple terms, it helps ensure that products are manufactured using controlled, repeatable processes designed to maintain quality standards over time.
CE and UKCA Marking
Products throughout the various BestHeating ranges carry relevant CE and UKCA markings.
These markings demonstrate compliance with applicable safety, health and environmental protection requirements within the UK and European markets.
How we test different product types at BestHeating
Different heating products require different validation processes, and BestHeating are committed to undertaking all the necessary procedures needed for each product category.
Central heating radiators
Central heating radiators are validated via:
- Pressure testing
- Flow performance testing
- Thread inspection
- BS EN 442 certification
These tests help to confirm structural integrity, accurate heat output performance and compatibility with domestic heating systems.
Electric heaters
Electric heating products undergo:
- Electrical safety checks
- Heating element performance testing
- Thermal behavior assessments
These evaluations help to verify safety, reliability and heating performance capability.
For customers exploring electric heating solutions, these tests are especially important because they assess both operational safety and long-term performance quality.
Smart heating products
Smart heating technology comes with the premise of additional testing requirements.
Products developed through BestHeating’s UK-based research and development facilities are assessed for:
- Software reliability
- User interface performance
- Electrical integrity
- Safety compliance
- Connectivity functionality
This ensures smart heating controls operate reliably while maintaining the same safety standards expected of traditional heating products.
What happens when something isn't right?
Quality assurance goes well beyond the point where a product reaches a customer’s home.
Feeback from customers, returns data and warranty claims are regularly reviewed by the BestHeating buying team, compliance department and customer service personnel to identify recurring trends and any potential issues to iron out.
If patterns emerge surrounding issues such as valve leaks, paint or finish inconsistencies, bracket defects, packaging concerns or manufacturing faults, that information is fed directly back into supplier review processes. Where appropriate, suppliers are required to implement improvements and corrective actions in reaction. And in extreme cases where standards cannot be maintained, products will be removed from the range altogether.
This feedback loop helps to inform and shape future purchasing decisions, ensuring that selections are made not only on the back of factory testing and certification, but in line with real-world customer experiences too.
Furthermore, positive feedback also influences future product and range expansion, signifying which products are most popular and continue to perform well in customers’ homes.
What customers are often surprised to learn about BestHeating
One of the most common misconceptions customers tend to make about BestHeating, and with regards to radiators in general, is that they receive little to no testing prior to sale.
In truth, multiple inspections, certification processes and performance assessments occur before a product appears available to buy online, let alone reach a customer’s home for installation.
Each radiator sold online by BestHeating is pressure-tested to 10 bar, flow-tested, thread-inspected and paint-adhesion tested at factory level before being approved for website listing. Further to this, these tests are then supported by independent certification, goods-in inspections and ongoing customer feedback monitoring and assessments.
The ultimate result is a process designed to promote and prioritise quality, consistency and long-term durability and reliability.
