What is the optimum temperature in a condensing boiler?

Condensing gas boilers are a great tool for saving energy at home and choosing the heating temperature that suits you best. If you do it correctly, you will not only save money, but also help the environment.

One of the greatest pleasures of winter is coming home to a warm and pleasant environment. A task in which having good heating is essential. To do this, you have options such as condensing boilers. These systems save energy and consume less than other more expensive options, especially those that work with electricity.

However, to achieve these savings without sacrificing comfort, it is important that you adjust the boiler temperature to your actual needs. It is useless to have the most efficient equipment on the market if you then select the maximum temperature of the heating boiler for no reason. This leads us to ask ourselves what is the most suitable temperature, which is exactly what we will deal with next.

How to estimate the right temperature

In general, for radiators to be efficient, the temperature at which the water circulating through them should be would be a maximum of 60 degrees . This would be the reference temperature for days when it is colder. The recommended outlet temperature, under normal conditions, would be approximately 50 degrees.

This would be the operating range for normal radiators, from 50 to 60 degrees. But if you have low-temperature radiators, then it is enough for the water to circulate at a temperature of approximately 35 to 40 degrees. As we can see, the thermal reduction of these models is considerable, which also translates into good energy savings.

In any case, the temperatures that we are commenting on are those of the boiler outlet and of the water, which influence what the radiators generate in the home. If we refer to the ambient temperature of the house, the optimal range of the ideal temperature at home is between 19 and 21 degrees , according to experts. In the case of the bedrooms and during the night, said temperature would be between 15 and 17 degrees. So, if you prefer, you can play with the temperature of the boiler to achieve that optimal room temperature. 

Why is temperature important?

Knowing the ideal heating temperature is key for two reasons. One of them is for comfort reasons. If your home is at the right temperature, you will not be cold or hot. Be careful, because the optimal temperature at home does not imply going home in short sleeves in the middle of January, but rather having a temperature that is suitable for the surrounding conditions. If your house is at 30 degrees, it is not at a suitable temperature. And the proof is that if you go outside in those conditions you have every chance of catching a cold.

The other reason is energy expenditure. Home heating is one of the most energy-consuming items in the home , and while condensing boilers are highly efficient, they also need to be used properly. So, if you bet on that comfortable temperature at home in winter, you will not spend more energy than necessary to heat your home. Something that not only helps the environment, but also your pocket.

Other tips to save energy

At this point, you know everything you need to know to adjust the heating temperature in your home and save energy in the process. But that saving does not end only here, since there are other things you can do to increase it: 

Maintain adequate pressure: Water pressure is a key element to save energy. If it is within the optimal parameters, between 1 and 1.5 bars, the boiler will work better, the pump will not have to make efforts and the heat loss during the water flow will be less.

Install thermostatic valves: These valves, together with the corresponding heads, have the capacity to save 8 to 13% of the energy used in heating. These valves allow the water flow to be closed or opened automatically, depending on the temperature of the radiators. So if they don’t need to be heated any further, the water bypasses and goes where it’s needed.

Bleeding the radiators: Bleeding the radiators is essential to maintain the correct operation of the system. The presence of air in the circuit causes problems and increases energy consumption, so you should not forget to purge it once a year. This task should always be done before the start of winter and with the boiler off.

Leave room for radiators: As their name suggests, radiators are designed to radiate heat around the area where they are installed. Therefore, it is necessary to leave the necessary space around it so that the heat leaves the radiator and mixes throughout the room. For this reason, you should remove the furniture that you have glued or very close to the radiator, avoiding placing clothes or any other unnecessary object on it.

Install a smart thermostat: As a last tip, we recommend that you consider buying a smart thermostat. Unlike conventional thermostats, these have the advantage of being autonomous in their operation and learn from your daily life . Therefore, they know when you are at home and when you are not, adapting the performance of the boiler to your specific needs. An ideal solution to save maximum energy and also optimize the pleasant sensations in your home.
