Choosing the right boiler and best performance to save energy and money it has been modified: 2017-01-16 di Benedict Flowers

Spending on heating can account for up to 50% of the annual domestic energy bill. Choosing the right boiler when designing the system, or replacing an old one, can also represent a significant reduction in consumption, a lower impact of the house on global pollution and finally a considerable saving of money.

Let's examine some topics to consider, which can help you choose the right boiler and configure the heating system, in order to obtain the best performance from the entire system.

Condensing boiler or traditional?

The condensing boiler is the type of more modern boiler, it allows to achieve very high performance in terms of energy efficiency, thanks to a technology that is able to recover the heat of the exhaust fumes reusing it in the heating process.

In conventional boilers the combustion fumes are expelled to a still very high temperature, between the 140 and 250 degrees. in condensing boilersInstead, the heat of these gases is still exploited to increase the water temperature of the heating circuit via a capacitor element called. In this way it sees almost completely the heat generated by combustion of the gas, in fact, the temperature of the combustion fumes of a condensing boiler is about 40 degrees.

How to make the most of the condensation?

The condenser, a key element of condensing boilers, by acting on the water of the heating circuit return is more efficient if this has a lower temperature. The condensing boiler is the ideal working conditions when it is inserted into systems that use water from the low-temperature circuit, as in underfloor heating, baseboard or wall.

However, even old radiator systems can be adapted to operate at low temperature, it can be done simply by increasing the hours of ignition, or by increasing the number of radiating elements.


Improving the Performance of the heating system?

  • Insulation. The correct insulation of the house compared to the outside plays an important role in the optimization of the heating system performance. Thermal coat and efficient glazed surfaces reduce heat dispersion, achieve and maintain the desired temperature will require less heat plant effort, reducing gas consumption.
  • Thermoregulation. It is a system that automatically adjusts the room temperature of the house making sure that the heating system provides the heat strictly necessary to reach the comfort conditions required by the user. Depending on the type of heating system installed, the thermoregulation can be zone, if a thermostat or chronothermostat controls the temperature of several rooms, or for a single room if through thermostatic valves the temperature can be controlled individually managing each radiating body.
  • Proper temperature management. At night or when you are not at home, it is advisable to lower the temperature. Even lowering from 20 to 18 degrees can lead to significant savings on your energy bill. To automate the lowering of the temperature it is possible to use a programmable thermostat or better still a remote control system, which besides the programming can guarantee greater flexibility and greater comfort. Being able to control the boiler via your smartphone we will be able to find the warm house even if we return early, or keep a lower temperature if our daily schedule has changed.
  • Other measures to optimize the yield of the system. Close the windows during operation of the system and prevent the radiators from being positioned in places not suitable for heat exchange, for example behind doors or inside furniture, or hidden from curtains.
