SUB-PAGE (https://saunierduval.com/home/service/eu-eco-design-and-energy-labelling-directives/) Soon new ErP regulations will change the way we heat our homes – Saunier Duval
[H1] Soon new ErP regulations will change the way we heat our homes This brief guide tells you what you need to know about the new regulations and how they will affect you [H2] What are the regulations all about? On September 26, 2015, new EU regulations impacting heating and hot water appliances will come into force. Know as the ErP (Energy Related Products) Directive they specify minimum energy efficiency and emissions standards for products and systems. After their introduction non-compliant appliances and systems will be progressively phased out. [H2] What products are affected? Boilers, combination boilers and central heating pumps; water heaters, domestic hot water pumps and hot water tanks. [H2] What else is new? From September 2015 heating and hot water related products will display an energy label. Just like the labels you are familiar with from domestic appliances such as washing machines and fridges, these classify devices according to efficiency bands. [H2] Is the best energy label always the right choice for me? The labelling has been specifically designed to help you make an informed choice when deciding on new heating and hot water solutions for your home. Nevertheless, it is worth noting that the best energy label does not necessarily always represent the best solution for you. As well as providing you with a fully compliant solution, your Saunier Duval installer can advise you on all your options. [H2] What is the most important change affecting me? One important result of the changes is that non-condensing boilers will be phased out after the regulations come into force. On some multiple occupancy dwellings however it will still be permissible to replace and old non-condensing boiler with a new one. To fully understand your options, speak to your Saunier Duval installer. [H2] How can Saunier Duval help? Saunier Duval has a range of compliant solutions for replacing, upgrading and making your heating and hot water systems more efficient. For most people wishing to replace an old non-condensing boiler, Saunier Duval’s easy condensing technology will be the best way to achieve energy efficient heating at an affordable price. For new buildings or modernisations, Saunier Duval also offers a variety A - A++ rated heating solutions that use proven solar systems featuring drainback technology or heat pumps to achieve maximum efficiency.

Your Diagnosis
Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.
Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)
These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.
Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.
Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.
Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.
Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.
Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.
Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

Home Services (Plumbing, Roofing, HVAC, Electrical) BS: Saunier Duval (saunierduval.com)
Saunier Duval is a legacy brand coasting on a 115-year timeline while operating a digital presence that is 80% hot air. The site is a masterclass in trust theatre, presenting unverified reviews and ‘spectacular’ performance claims while failing to implement even basic Organization schema or a unique homepage H1. It functions as a hollow corporate shell that prioritizes vague superlatives over measurable technical authority.
Immediately implement Organization and Product schema with SameAs links to the Vaillant Group parent company and verifiable social profiles to close the identity gap. Eliminate the redundant /home/ URL and replace it with a ‘Case Studies’ page featuring real-world energy saving data to back the ‘spectacular savings’ claim. Replace fluff-heavy headings like ‘Quality meets reliability’ with specific technical achievements or certification logos (e.g., ISO or CE certification details). Add external verification links to Google Reviews or industry-specific trade bodies to provide an actual proof path for testimonials.
The content perfectly aligns with the Home Services and HVAC manufacturing sector. It references specific boiler products (Themafast), heating technologies (GeniaAir), and installer networks, confirming its position as an equipment manufacturer and service provider.
“The score of 60 is primarily driven by the 'Trust and Proof' pillar (17/20) and 'Information Density' (16/30). The total absence of schema and proof links, combined with the technical failure of duplicating the homepage on a sub-page, signals a high distance between the brand's 'expert' claims and its digital substance. While the partner directory and regulation guide provide some utility, they do not outweigh the generic marketing saturation of the primary pages.”
