Installation and fitting of HVAC equipment in Barcelona

Installation of hot and cold water supply systems in Barcelona:

from design to commissioning


A reliable water supply is the foundation of comfort in any home. In Barcelona, where many buildings are quite old, residents often face problems such as low pressure, limescale or worn-out pipes. HVAC Barcelona (www.hvac.barcelona) carries out a full range of work on the installation of hot (DHW) and cold (CHW) water supply systems in flats, offices and private homes.

 

 



Working in the capital of Catalonia, our engineersater supply problems in Barcelona and their solutions solve specific regional problems on a daily basis:
Hard water: The water in Barcelona has a high lime content. We install decalcification systems (water softeners) that protect your household appliances, boilers and mixers from rapid breakdown.
Low pressure on upper floors: In older buildings in the Sants or Poblenou districts, the pressure often falls short of the norm. We install silent booster pump stations to ensure your shower works perfectly.
Old lead pipes: In older buildings, we completely replace hazardous pipes with modern, environmentally friendly materials (cross-linked polyethylene PEX, multilayer polypropylene or copper).

 

Water supply installation services from HVAC Barcelona
We offer a comprehensive approach that complies with the Spanish Building Code (CTE - Código Técnico de la Edificación):
Hot and cold water distribution: We install manifold distribution systems, where each point (bathroom, kitchen, toilet) has its own independent line. This ensures that there are no pressure drops if someone turns on the water in different places at the same time.


Installation of water heating systems:
Gas water heaters and storage tanks: Fast heating of large volumes of water.
Electric thermos flasks: Selection of the optimal volume (from 50 to 300 litres) taking into account the number of residents.
Aerothermal boilers: An energy-efficient solution that allows you to save up to 75% on water heating costs.
Installation of filtration systems: From simple coarse filters to reverse osmosis systems for obtaining drinking water directly from the tap.
Plumbing installation: Installation of fixtures, mixers, shower cabins and leak protection systems.
