The latest trends aimed at promoting energy savings and lower emissions of pollutants to generate heating, air conditioning and domestic hot water in residential buildings, have led to the adoption of single-use systems with centralized production.

This type of approach allows individual users to determine the use of heating and domestic hot water based on their own criteria, using a central element that offers high performance and lower CO2 emissions

Obviously, the system presents a series of technical and administrative characteristics focused on an individual use in which a rational use of energy and an individualized service for each user is a priority. For this reason, Sunflower offers an exclusive and differentiating service in all its energy management, consisting of indefinite attention (24 hours a day / every day of the year) of the individual installations of the users with travel and labor included. It also provides a web for viewing and downloading your bills, as well as the average consumption of your community.

At Sunflower, an energy services company (ESE-ESCO), we know that nota ll communities are the same, that is why we have developed different management alternatives so that communities can choose the model that best suits their needs.


Only users registered in the system pay the ESCO (ESE) their heating, climatization and domestic hot water...


All the co-owners pay the ESCO (ESE) part of their heating, climatization and domestic hot water according to the consumptions registered by their meters...


The Community pays the ESCO (ESE) heating, climatization and domestic hot water according to its meter readings...

Heating, air conditioning and domestic hot water are some of the basic services that contribute to the well-being of a home. At Sunflower we are aware of their importance and that is why we offer our comprehensive advanced maintenance program for centralized systems.

It begins with a technical report of the installation, which includes a review of all its elements, as well as an annex with areas for improvement: optimization of performance, savings proposals, compliance with regulations, etc.

It includes both preventive maintenance with periodic revisions and special attention to fuel consumption reduction, and corrective maintenance with immediate attention 24 hours/365 days a year for incidents or breakdowns.

Within our maintenance programs, the Community can choose any of these different modalities:


Preventive and corrective maintenance in the energy production room and solar panel installations or cogeneration equipment, if existing in the building.


Traditional maintenance + any of these options: pressure groups, general distribution networks, individual installation and administrative management for the distribution of the cost of bills among the co-owners.


Advanced maintenance + Mantenimiento avanzado + free replacement of parts and labor. Specially designed for homeowners’ communitiones looking for stability in the anual budget.

This is only possible with a qualified team that provides innovative solutions and responds to current energy needs, with an eye always on sustainable development.


Energy Service Companies (ESE), or ESCOs, are organizations that provide energy services at a given user's facilities, with payment for services being based on the achievement of energy savings. These savings will be achieved through the development of energy efficiency improvements in the facilities or through the use of renewable energy sources.

ESCOs can thus design, finance, install, commission and control a given project, assuming all or part of the technical and economic risk of the project, even guaranteeing the savings to be achieved through penalties in the event of failure to do so.
