A complete aerothermal installation is a serious project. It starts with calculating the thermal loads of the home, sizing the equipment according to real needs, choosing between only radiators, only underfloor heating or a combination, planning space for the DHW tank and outdoor unit, and a fixed price quote. Air-to-water heat pumps, also called aerothermal systems, go a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fancoils to climatise the home, and at the same time heats a domestic hot water tank of approximately 200 litres for use in 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.

In winter, when humidity drops and dry westerly winds blow, wood contracts. The door closes well but there is a visible gap between the door and the 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 move, or learn to live with it and adjust the hinges as needed. 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 changes in humidity. 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 or side frame, and forcing it closed only worsens the hinge. Traditional knob hinges, those seen on old construction doors, are not adjustable. If the door rubs, wood must be planed down or 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 again.

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 regulating 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.
