The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to climatise the home, and simultaneously heats a domestic hot water tank of approximately 200 litres for showers and taps. It solves everything with a single unit, ideal for chalets and large homes. Its payback 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 load of the home, sizing the unit according to real needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the DHW tank and outdoor unit, and a fixed quote.

Traditional knob hinges, found on old built-in doors, are not adjustable. If the door rubs, you need to plane off wood or replace the hinges with modern adjustable models. Planing wood is the usual solution when the problem is seasonal. We remove 1-2 mm from the rubbing area, seal the cut, and the door closes properly again. It's a very specific pattern in the area. Solid interior wooden doors, especially those in blocks from the 80s-90s, swell and shrink with seasonal humidity changes. In summer, when humidity and temperature are high, the wood absorbs moisture from the air and expands. The door no longer closes well, rubs against the top or side frame, and forcing it only damages the hinge. In winter, when humidity drops and the dry westerly wind blows, the wood shrinks. The door closes well but there's visible looseness between the door and the frame, allowing air and noise to pass. This is the natural cycle of wood and can only be avoided by either replacing it with an MDF or MultiLam door that doesn't move, or learning to live with it and adjusting the hinges occasionally.

For more modern windows with tilt-and-turn profiles and thermal breaks, the hardware is of better quality but also requires maintenance. Lubricating the hinges and adjusting the locking points every 2-3 years considerably extends their lifespan and prevents air entry in winter or making them too stiff to open.
