The air-to-water heat pump, also known as aerothermal energy, goes a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to regulate the home's climate, and at the same time heats a domestic hot water tank of approximately 200 litres for showers and taps. It solves everything in a single unit, ideal for detached houses and large homes. Its payback period compared to a traditional gas + air system is 8 to 12 years in the local climate. A complete aerothermal installation is a serious project. It starts with calculating the home's thermal loads, sizing the equipment according to actual needs, choosing between only radiators, only underfloor heating or a combination, planning space for the domestic hot water tank and outdoor unit, and a fixed quote.

We identify the real cause (humidity, settlement, worn fittings) before taking action. This is a very specific pattern for the area. Solid wood interior doors, especially those in blocks from the 80s-90s, swell and contract with seasonal humidity changes. In summer, when humidity and temperature are high, the wood absorbs water from the air and expands. The door stops closing properly, rubs against the top frame or side, and forcing it closed only worsens the hinge. In winter, when humidity drops and dry westerly winds arrive, the wood contracts. The door closes well but there's a visible gap between the door and frame, which allows air and noise to pass through. This is wood's natural cycle and can only be avoided in two ways: either replace it with an MDF or multi-layered door that doesn't exhibit this movement, or learn to live with it and adjust the hinges periodically.

For more modern windows with tilt-and-turn profiles and thermal break, the fittings are of better quality but also require maintenance. Lubricating the hinges and adjusting the closing points every 2-3 years significantly extends their lifespan and prevents air from entering in winter or making them too difficult to open.
