Semantic Coherence: Saunier Duval – Signal Evidence & AI Readability

Semantic Coherence — The Lens

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.

Semantic Coherence Homepage promise vs. Sub-page reality.

The homepage promises ‘A brand you can rely on’ and ‘A lifetime of expertise,’ which is partially supported by the partner directory on sub-pages. However, there is a technical drift where the primary navigation leads to an identical copy of the homepage (/home/), creating a recursive loop of marketing claims. The ‘Service’ sub-page shifts to a purely regulatory tone regarding EU ErP directives, which, while informative, feels disconnected from the ‘dynamic partner’ persona established in the hero sections.

Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.

[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?
