A complete aerothermal installation is a serious project. It starts with calculating the thermal loads of the home, sizing the equipment according to actual 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. 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 air-condition 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 detached houses and large homes. Payback compared to a traditional gas + air system is 8 to 12 years in the local climate.

For a property on the Costa Blanca with existing underfloor heating that has started to fail (cold zone, no heating, leak, circulation noise), diagnosis requires specific tools. A thermal imaging camera to identify malfunctioning circuits, an electronic leak detector to locate leaks without damaging the floor. Pressure gauges to check circuit pressures. In most cases, we can diagnose and repair without lifting the entire floor. The most common repairs include: Replacing electro-thermal manifold heads that have failed and are blocking a complete circuit, replacing the circulation pump when it no longer provides sufficient flow, balancing the circuit when there are thermal imbalances between zones. Complete bleeding when there is air in the system. Leaks in embedded pipes are the most serious but also infrequent issue. Quality multilayer pipes have a 50-year guaranteed lifespan. When building or undertaking a full renovation, the decision on the heating system has a significant impact on comfort for the next 30-40 years. A decade ago, the standard answer was radiators with a boiler. Today, water-based underfloor heating combined with aerothermal heating is what we install most often in modern new builds on the Costa Blanca, especially in detached houses and large homes. The reasons are varied and all point to comfort and efficiency.
