Hydrogen in buildings: a long-term view

You're hearing more and more about decarbonized gases on job sites and from your clients, but between promises, costs, and constraints, it's hard to know what will actually hold up over 10 to 20 years. Your challenge is spotting the credible use cases, the equipment that might arrive, and the points of attention on safety, network, and maintenance, so you can advise without overselling. Here's a simple sort-through, to help you decide when to keep an eye on the topic, and when to stick with solutions that are already robust.

Kitchen hood and mechanical ventilation: compatibility and best practices

When you fit a kitchen extraction system in a home equipped with mechanical ventilation (VMC), everything hinges on airflow balance. Properly connected and properly set, it prevents odor backflow, unnecessary depressurization, and clients who call back. A few simple checks on the ductwork secure the installation and save you time on the job site.

Optimised CESI vs CESI with separate backup

On a solar hot water job, the real pitfall is the backup heater. Whether it's built into the tank or kept separate, it changes your hydraulic diagrams, the controls, the space needed in the plant room, and above all the maintenance you'll be committing to. By clarifying your constraints upfront, dwelling type, available power, continuity of service, you choose a solution that's simpler to install and more reliable to run, without service call-backs that drag on.

Collective electric heating: what future?

In a co-owned building, the question of collective heating usually comes down to three points: real comfort in the flats, controlled service charges, and work that can be carried out without blocking the site for months. You have a key role in making a simple diagnosis, comparing scenarios, and securing a solution that passes the general assembly vote without bad surprises. And if the right option isn't the one people initially assumed, all the better: you save everyone time.

Radiant asymmetry: the cold wall in winter

In winter, no matter how much you heat, a “cold” wall can be enough to create a sensation of draught. This difference in perceived comfort between two sides of a room — asymmetry — comes mainly from radiant heat exchange and a poorly insulated wall or an underperforming window. As a tradesperson, being able to identify it quickly means you save time choosing the right fix: insulation, thermal bridge treatment, or window replacement.

Thermal break connectors: solutions for new-build and renovation

When you're treating insulation, junction zones can ruin the result, even with good materials. In both new-build and renovation, the right thermal break connector needs to be chosen early, installed cleanly, and checked, otherwise heat loss and condensation come back to haunt the job. With a simple method and the right execution details, you secure performance and client satisfaction.

Three-way valves and temperature control

When a control system "hunts" between too hot and too cold, that's often where you lose comfort and kWh. In renovation, properly managing flow rates and mixing lets you stabilise temperature, protect the heat pump or boiler, and avoid the lukewarm returns that drag down efficiency. Here we get straight to the point to help you choose and adjust without a headache.

Population ageing and thermal comfort

As your clients grow older, thermal comfort becomes a health issue as much as a wellbeing one. It's up to you, as a tradesperson, to propose work that's simple to explain and genuinely effective — targeted insulation, well-adjusted ventilation, suitable heating — to avoid rooms that are too cold in winter and stifling in summer. You gain clarity, they gain daily peace of mind.

Felt temperature vs air temperature: why surfaces matter

In a home, the air can read 20°C and yet still feel cold. Surfaces are often what makes the difference, a wall or a window "draws" heat from the body and pulls the felt temperature down. As a tradesperson, spotting these cold surfaces, then acting on insulation and airtightness, is the surest way to deliver a genuinely pleasant atmosphere, without pushing the heating up.

Thermal bridges: the weak points of the building envelope

On a job site, heat leaks don't always come from large surfaces, but often from junctions. You save time and gain performance when you spot these risk areas from the first visit, then coordinate insulation, joinery and airtightness in the right order. This is often where the client's comfort is decided, and your margin on callbacks.
