The air-to-water heat pump, also called aerothermal heating, goes a step further. The outdoor unit heats or cools water that circulates through radiators, underfloor heating, or fan coils to condition the home, and simultaneously heats a domestic hot water tank of approximately 200 litres for showers and taps. It resolves 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 home, sizing the unit according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the DHW tank and the outdoor unit, and a fixed quote.

The real risks detected by annual maintenance are varied. Microscopic gas leaks that only manifest under extreme conditions. Heat exchanger with fine cracks that allow combustion gases into the hot water circuit. Uncalibrated safety valve that fails to open when it should in case of overpressure. Soot accumulation in the burner reducing efficiency and increasing emissions. Deteriorated thermocouple that fails to shut off the gas when the flame goes out. Any of these issues, ignored for years, can lead to carbon monoxide in the home, gas leaks, or tank rupture. The best time is October or early November, just before the first significant heating use of the season. This prevents any detected problem from catching you with the heating already in heavy use. It also avoids the typical November rush when everyone tries to fix their heating that won't turn on. Home insurance may deny coverage for incidents. Risk of serious breakdown not detected in time. Possible penalty from neighbourhood inspection.

Manufacturer's official warranty (5-7 years) plus our labour coverage. 5-7 years manufacturer's warranty depending on the brand (Daikin, Mitsubishi, Bosch, Vaillant). Plus our 30-day labour coverage and recommended annual services. The most common repairs are varied. Replacement of electrothermal collector heads that have failed and are blocking a whole circuit, replacement of the circulation pump when it no longer provides sufficient flow, circuit balancing when there are thermal imbalances between zones. Complete bleeding when there is air in the system. Leaks in embedded piping are the most serious but also infrequent issues. Quality multilayer pipe is guaranteed to last 50 years.

The price for aerothermal heating in La Salut typically ranges between €188 and €2240. The final figure depends on the property's condition, materials, and labour time.
