An air-to-water heat pump, also known as aerothermal heating, goes a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to regulate the indoor temperature, and at the same time heats a domestic hot water tank of approximately 200 litres for showers and taps. It solves everything with 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 thermal loads of the dwelling, sizing the equipment according to real needs, choosing between radiators only, underfloor heating only, 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 hardware) 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 there is high humidity and high temperature, 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 a visible gap remains between the door and frame, allowing air and noise to pass through. This is the natural cycle of wood 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 as needed.

Official manufacturer's warranty (5-7 years) plus our coverage on labour. For more modern windows with tilt-and-turn profiles and thermal break, the hardware is of better quality but also requires maintenance. Lubricating the hinges and adjusting the closing points every 2-3 years significantly prolongs their lifespan and prevents air from entering in winter or them becoming too difficult to open. 30 days on the repair. Somfy motors with official manufacturer's 5-year warranty.
