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 home's temperature, and at the same time heats a 200-litre domestic hot water tank for showers and taps. It solves everything in one 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 begins with calculating the thermal loads of the home, 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.

Traditional knob hinges, those seen on old building doors, are not adjustable. If the door rubs, wood must be planed down or the hinges replaced 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 is a very specific pattern in 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 well, rubs against the top or side frame, and forcing it closed only worsens the hinge. In winter, when humidity drops and dry westerly wind comes in, the wood contracts. The door closes well but there is a visible gap between the door and frame, allowing air and noise to pass through. This is the natural cycle of wood and can only be avoided with two things: either replace it with an MDF or multi-layered door that does not have this movement, or learn to live with it and adjust the hinges as needed.

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 extends their lifespan and prevents air from entering in winter or them becoming too difficult to open.
