How to keep your home warm this winter (and how can aerothermy help you with it)

Winter is approaching in some regions in the world. In those places, days are becoming shorter and temperatures are already dropping. Those who live in the Northern hemisphere are getting ready for the last season of the year and dreaming of a cozy home where to spend the quieter months. But many people are more afraid of the heating bills than they are of the cold.
We are here to help with some tricks to boost your heating system efficiency at home. These tips will help you lower your heating bills while increasing your comfort at home.
How to boost your heating system efficiency
Make the most of your curtains and blinds
During the day, let the sunlight (and the natural warmth it brings) in, particularly in your south-facing windows. At sundown, close the curtains and blinds so the windows are better insulated and you can stop heat loss through them. It is estimated that between 10-25% of a house heat is lost through the windows.
20 -21ºC is enough
One degree less at home can make a dramatic difference in your heating bill (you can expect to see a cost reduction of 3% per degree less in a 24-hour period). Many people set their thermostats around 23 ºC but, actually, 21ºC or 20 ªC is enough to feel comfortable at home if you are wearing some long-sleeved garments. In fact, it is a good idea to set the temperature as low as it is comfortable for you.
When you are sleeping you can even turn the thermostat back around 15ªC or even less (up to 10 ºC). You don't need any heating when you are not at home.
Your best bet for maximizing efficiency is having a programmable thermostat.
Close the doors
Close the doors of the rooms that are not being used at that moment in your home to prevent warm air escaping into them, including body heat from the occupied areas. You want to keep heat in the room you are in.
Seal any air leaks
Find where the air leaks are at your home and then seal them with silicone caulking, insulating foam or weather-stripping for the windows and doors. It will also help you to reduce noise.
Prevent heat loss from your fireplace
If you aren't burning any fire, don't let your fireplace damper open: It's like letting a window wide open! You will be letting warm air out and cold air in.
Help heat float without obstacles
Make sure that there aren't any large pieces of furniture or objects right in front of your heating system, blocking the warm airflow. Air needs to circulate freely, so rearrange everything in the room if necessary.
Use carpets
Carpets will isolate your feet from the cold in the ground. In a bathroom, instead of wool carpets, you can use natural fibre (such as jute or sisal) carpets on the floor.
Keep the right level of moisture
This might sound counterintuitive, but it is essential to keep the right level of moisture in the air. During winter months, the air tends to be drier and heating a room can further evaporate humidity. This dryness not only makes the air feel colder, but it also prevents air to retain the heat for a longer period. The ideal indoor humidity level during winter should be 30-40%.
Houseplants are a good way to regulate moisture levels. It is also helpful to keep small bowls of water near your heating system.
Switch to an aerothermal heating system
Aerothermy is not only a more sustainable heating alternative, but it is also considered a new source of renewable energy. It requires less energy consumption, which translates to lower costs.

What is aerothermal technology?
Aerothermal technology takes advantage of the thermal energy existing in the air, an inexhaustible energy source. This means you no longer will need gas or fuel, making it also a safer alternative.
Aerothermal systems can both be used to heat a room or cool it, and they can even provide sanitary hot water.
How do aerothermal systems work?
Aerothermy extracts the thermal energy from the air, bringing heat inside or outside your home as necessary. Aerothermal systems use a closed circuit with a cooling gas. Increasing the air pressure in the gas heats the air. The heat pump then transfers this energy to where it is needed, from outside your home to inside of it, heating it, or vice versa, cooling your house after the heat has been expelled and the pressure has lowered down in the circuit.
This works because even cold air has "heat" (thermal energy) in it. In the process, aerothermal equipments create more energy than they use: this is the reason they are considered to be a source of renewable energy.
What are the benefits of aerothermal heating systems?
Aerothermal systems provide great advantages over traditional heating and air conditioning systems:
●      They are green, as they use a renewable energy source.
●      Although installation is more expensive than in traditional equipment, they are cheaper to use, as they require less energy (low consumption system).
●      They are safer since they don't use any fuel.
●      They are versatile systems, able to provide heating and sanitary hot water as well as air conditioning.
●      They can use specialized low-temperature radiators, fan coils or underfloor heating. They are compact and easy to install.
●      They change the temperature without modifying moisture levels, thereby positively affecting air quality and people's general well being.
Hitachi's Yutaki S heat pumps are a prime example of aerothermal technology at its finest. They provide comfort all year round delivering heating, cooling and hot water with a wide operating range of 20ºC to 46 ºC.
Besides the reduced power use compared with traditional systems, it is also compatible with solar panels for even greater savings. The Yutaki S has also four different energy-saving power modes to choose from, so you can its use to your current lifestyle and preferences.
