In a water heater, the anode does the quiet job that keeps you from getting a callback for a perforated tank. Magnesium, titanium or impressed current, each solution has its own installation habits, checks and pitfalls, and that's often where everything is decided. Get this choice right and you secure the installation's lifespan and your client's peace of mind.

On an external wall insulation job, the real headaches rarely start on the large façade surfaces. They happen at window reveals, sills, parapets, and all those small junctions that decide whether the finish is clean or whether rework keeps piling up. By mastering these singular points, you save time, secure the sealing, and deliver a clean result, without last-minute improvisation.

Ground sealing is not primarily a question of material, it is a question of threshold and zoning. Above one hectare of project area, stormwater discharge moves into a water-law procedure; below it, the municipal stormwater zoning takes over and can require infiltration on the plot itself. Find out which of the two applies before you price the job, not after the refusal.

On site, bonded and mechanically fixed EPS remains a safe bet when you need an exterior system that's fast to install, well mastered by crews, and easy to price. If you secure the substrate, flatness, and layout from the start, you save time on rework and avoid disorders that get expensive in callbacks. Here's a rundown of the right installation habits, the ones that make the difference between a façade that's just "put up" and one that lasts.

When you have a doubt hiding behind a wall lining or inside a partition, the right move is to look rather than assume. With a quick, clean visual inspection, you can spot compressed insulation, damp, or duct runs without opening everything up. The payoff is a more reliable diagnosis and a better-controlled job, from the very first drill hole.

When the load-bearing wall also acts as insulation, you save space, simplify site details, and limit thermal bridges from the design stage onward. On the ground, everything comes down to your material choices, moisture management, and envelope continuity, especially around floors and window openings. Well designed, this approach gives you a solid, high-performing "all-in-one" wall that is easier to explain to your client.

When you insulate from the inside, you quickly gain comfort, but you also risk losing the "buffer" effect of the walls that stabilizes temperature. Good news, the dilemma isn't inevitable. By choosing the right materials, properly handling airtightness, and keeping some mass on the room side, you can aim for a clean, high-performing, comfortable job.

The decision turns neither on litres nor on the headline price: it turns on the load profile declared under Regulation (EU) No 814/2013 and on the power the incoming supply can actually deliver. An instantaneous electric unit able to hold a shower draws a current no domestic single-phase service will give you. Here are the two tables to take to the survey.

You can gain comfort without trapping moisture or weakening the existing structure, as long as you choose compatible materials and careful installation. Get it right, and you protect the building, the schedule and performance, with no bad surprises on site.

A poorly connected intermediate floor is often where heat loss hides and where callback after callback for finishing snags starts to pile up. As the tradesperson, you're the one who can treat this sensitive point cleanly, without adding weight to the job or complicating the networks. With the right moves, you gain client comfort and measurable performance from the very first heating season.

Between a heat pump water heater and a solar water heater, the choice turns neither on the COP nor on the headline price. It turns on the tapping profile the appliance has to hold, set by Regulation (EU) No 814/2013, and on a non-combination rule that took effect on 1 January 2026: the heat pump cylinder loses its energy-scheme payment as soon as a heat pump appears on the same quotation.
