Aerothermal installation in Madrid
An air-to-water heat pump system is designed as a system: heat pump, emitters, domestic hot water, hydraulics, and regulation. Replacing the generator without reviewing the rest may leave a poorly adapted solution.
¿Qué necesitas resolver?
Primero, entiende qué está fallando.
Tell us what is happening, when it started, and if a fault code appears. Brand, model, and exterior photographs help prepare the consultation. The diagnosis determines if it is advisable to repair; an isolated symptom does not confirm a faulty part.
Preventing is not the same as repairing an existing fault.
If the equipment is functioning, compare the scope of a review and the conditions of maintenance. Cleaning, checks, spare parts, and corrective visits are not the same: review what the proposal includes before contracting.
Compare the complete solution, not just the device.
La selección del equipo y su instalación deben adaptarse al hogar. Solicite un alcance que separe el suministro, las conexiones, las adaptaciones y la puesta en marcha. Si está considerando reparar o reemplazar, compare ambas estimaciones con el estado del equipo actual.
New boilers, with specifications and prices for comparison.
Explore the catalog by brand, model, and budget. Check dimensions, features, and documentation for each boiler. The purchase of the equipment does not include installation: you can inquire about that service separately.

Scope of service
Scope: air-to-water heat pump systems and their associated elements, depending on configuration. The supply temperature, demand, and regulation influence operation. Power and savings cannot be assigned without knowing the building and the installation.
Study the demand and the emitters
To propose a solution, it is necessary to know the building, insulation, climate, usage, and emitters. The temperature regime of radiators, underfloor heating, or fan coils affects operation. Compatibility and savings cannot be guaranteed based solely on the surface area of the home.
Domestic hot water and hydraulic configuration
It is necessary to define whether the system produces domestic hot water, how it is accumulated, and how the zones are distributed. The hydraulic scheme must justify the planned elements, their capacity, and control. An inertia tank or accumulator is not selected solely based on the available space.
Location, electricity, and scope of work
The external location, ventilation, maintenance access, noise, and electrical supply must be reviewed. The proposal must distinguish between equipment, hydraulics, regulation, adaptation of emitters, construction, and auxiliary means, as well as applicable checks and documentation.
Compare the complete project
Request a list of references and a detailed scope. The cost of use depends on demand, temperatures, regulation, and rates; it does not equate to the nominal power or the instantaneous consumption indicated in a data sheet. Any available subsidies are verified according to the current call and are not assumed.
Information for preparing the inquiry
- Brand and references of the outdoor unit, hydraulic module, and control.
- Installed emitters: underfloor heating, radiators, or fan coils; existence of domestic hot water storage.
- Operating mode affected, control alerts, and recent changes in the installation.
Add locality and access conditions. Only send photographs that you can take without disassembling equipment or exposing yourself to risks.
Your questions answered
Lo que debes saber antes de decidir
Faults, installation, maintenance, and purchasing new equipment: find answers for your system and prepare your inquiry.
Can it work with the existing radiators?
It depends on its capacity and the demand at the expected operating temperature. A study is required; it cannot be assured by the type of radiator alone.
Can a fixed percentage of savings be guaranteed?
Not without a comparison with hypotheses and specific data. Usage, insulation, temperatures, and energy prices change the outcome.
Does an installation include cooling?
Only if the design, emitters, control, and contracted scope include it. Not all air-to-water heat pump systems offer the same functions.
¿Qué información necesito saber si pueden manejar mi caso?
Indicate the equipment, brand, model, locality, and what you need: repair, install, or maintain. Add access conditions if they affect the intervention. The page describes the service; availability, scope, and the visit are confirmed upon inquiry.
¿Qué debe quedar claro antes de aceptar un presupuesto?
Solicite el alcance por escrito: diagnóstico, desplazamiento, mano de obra, materiales y posibles trabajos adicionales. Verifique qué está incluido y qué está excluido, los impuestos y las condiciones aplicables. Si el diagnóstico cambia la propuesta, pida confirmación antes de autorizar nuevas acciones.
Does buying a boiler in the store include installation?
No. Buying the boiler and having it installed are separate services. The product page shows the model's price and what is supplied. Installation requires assessment of the location, connections, flue and any necessary adaptations. Ask for the two costs separately before deciding.
What photos help prepare the inquiry?
An overview of the equipment, its model label, and the warning displayed on the screen. In a replacement, the connections and the space around it are also helpful, always from a safe position. Do not remove casings or protections to take photos; avoid including unnecessary personal data.
Does the presence of ice on the outdoor unit confirm a malfunction?
No se puede concluir únicamente a partir de eso. Describe cuándo aparece, si desaparece durante la operación, cualquier alerta y si afecta la calefacción o el agua caliente sanitaria. Consulta el manual del modelo y solicita una revisión si el funcionamiento es anormal; no retires el hielo golpeando o manipulando componentes.
Why does the heating work but not the hot water?
Es necesario conocer la configuración de la producción y almacenamiento de agua caliente sanitaria y lo que indica el control. Envíe referencias para la bomba de calor, módulo hidráulico y acumulador si están presentes, junto con la alerta. El síntoma por sí solo no identifica un sensor, válvula o ajuste específico.
Is a higher capacity heat pump always the best?
No. La selección debe relacionarse con la demanda, los emisores, las temperaturas, la modulación y las necesidades de agua caliente sanitaria. Compara el proyecto completo, incluyendo la regulación y la hidráulica. Elegir basándose en la potencia máxima del catálogo sin revisar el edificio no garantiza una instalación bien adaptada.
What should a maintenance plan for air-to-water heat pump systems identify?
Las unidades y elementos cubiertos: heat pump, hydraulics, storage, emitters, or control, según el alcance acordado. Debe distinguir las operaciones preventivas, incidentes, partes y exclusiones, así como la frecuencia correspondiente al equipo y la instalación.
¿Qué se debe revisar antes de elegir la ubicación de la unidad exterior?
Espacio, ventilación, acceso técnico, drenaje de agua, enrutamiento de conexiones y condiciones acústicas del sitio. La figura sonora del catálogo no resuelve únicamente la ubicación. Comunique distancias, obstáculos y restricciones de construcción para estudiar una solución específica.

Antes de decidir sobre su sistema de bomba de calor aire-agua
Equipos y emisores
Indicate the model and whether it works with underfloor heating, radiators, or fan coils. The operating temperature influences the evaluation of the system.
Calefacción, agua caliente sanitaria o aire acondicionado
Clarify what functions the installation has and which ones are failing or you want to incorporate. Not all air-to-water heat pump systems offer the same features.
Complete project
Equipment, hydraulics, control, and emitters must be evaluated together. Savings cannot be promised or power selected solely based on square meters.
Repair or replace? It doesn't just depend on age.
Evaluate the repair
It makes sense to consider repair when the fault is localized, there is a compatible spare part, and the rest of the equipment is in good working condition. Request diagnosis, scope, and cost before deciding.
Considerar recambio
It is advisable to compare alternatives if there are recurring faults, if a spare part cannot be obtained, or if the equipment no longer meets your needs. Include installation adaptations in the comparison; the price of the unit is not the total cost of the change.
No hay un porcentaje universal de ahorro o número de años que mandate el reemplazo. La decisión requiere evaluar el equipo y su instalación.
