The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fancoils to air condition the home, and at the same time heats a 200-litre domestic hot water tank 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 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 domestic hot water tank and outdoor unit, and a fixed price quote.

In winter, when humidity drops and dry westerly winds blow, wood contracts. The door closes well but there's visible play 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 have this movement, or learn to live with it and adjust the hinges occasionally. This 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 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, you need to plane down wood or replace the hinges with modern adjustable models. Planing down 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 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 them becoming too difficult to open.
