The good things and the not-so-good things about boilers.
The centralized installation of column heating was very common several decades ago and presents drawbacks with a high degree of dissatisfaction for its users.
The typical problems of this type of distribution are:
- Distribution of non-uniform heat in all dwellings according to the situation of each dwelling due to poor distribution of flows. This leads to a lack of comfort in many homes, either due to excess or lack of heat.
- Outdated radiator valves and most of them without any regulation capacity.
- High energy consumption.
- Ineffective and unfair system of distribution of heating costs by property coefficients. Some users must even resort to alternative systems to heat their homes, although they pay the same as the housing that has 26ºC.
Usually wrong measures are taken to solve these problems:
- Increase the flow of the installation to try to satisfy the owners who complain about lack of temperature, which further aggravates the problem.
- Increase the temperature in the boiler to achieve a higher flow temperature.
This results in an excess of fuel consumption and deterioration of the components of the installation when subjected to higher working temperatures.
- The regulation for windows that is closest to the boiler room, which consists in opening the window so it can eliminate the excess of heat creating a great waste of energy.
- Sometimes the community considers the total reform of the installation to turn them into individual installations.
A viable solution that has two major drawbacks: the high cost and the inconvenience caused by the works.
Advantages of central heating
Contrary to what is thought, a central heating system has great advantages with respect to the individual:
- The cost of installing a single centralized system is lower than the cost of the sum of many individual heaters.
- The transformation of the centralized system of a boiler service into an individual system involves rather expensive works.
- In the centralized systems it is possible to use different fuel.
- The thermal power that must be installed to heat a community of owners with a single centralized boiler.
It’s less than the sum of the powers needed for so many individual heaters: therefore the relative energy consumption is greater in the individual systems.
- The centralized boiler has a longer life than individual boilers.
- The thermal performance of a single centralized boiler is better than that of many individual boilers.
- Maintenance and control expenses by public entities are lower in centralized systems, since the costs are divided among all the neighbors.
- Centralized systems are more secure.
