The power will be the result of the product of 4 variables: area of ​​the environment (m2), orientation of the house, level of insulation and the climatic region of the country in which it is located.

How many kW per square meter aerothermal?

8kw for a small flat. 11 for a normal house 100/120m2 and 16kw for a large house.

How many kW does it take to heat a house?

If the house is not thermally insulated, which is the most common, at least 0.1 kW of power is required for each square meter. Therefore, to heat an area of ​​100 m2 we will need a fireplace that has a power of 10 kW and above, approximately.

How is the power of a boiler calculated?

CALCULATE THE POWER OF THE BOILER

Part of the base that you must multiply 100-115w per m2 of the surface of your home. These are the most common ranges installed for domestic use: 20kw: it is the minimum power that boiler manufacturers usually distribute.

How much savings with aerothermal energy?

Aerothermal energy can represent a saving of 65% compared to natural gas systems. For example, in a single-family home of about 200 m2 that uses aerothermal heating, it consumes about 4,500 kilowatt-hours per year.

When is aerothermal energy profitable?

It can be ensured that with an aerothermal system savings of 80% are achieved with underfloor heating and up to 70% in radiator heating if we compare it with a diesel boiler.

Which is cheaper aerothermal or natural gas?

The results unequivocally indicate that the energy cost of aerothermal heating systems is at least 25% cheaper than natural gas and 50% cheaper than diesel.

What is boiler power?

The net power of a Boiler corresponds to the Heat Power needed to evaporate a quantity of water in certain conditions and transform it into steam in other different conditions of pressure and temperature.

What boiler power do I need for a 90m2 flat?

Up to 100 m2 of housing a very powerful boiler is not needed, any model that offers at least 15 kW of heating power will be enough to cover the surface. If the house has more than 100 m2, the power must be increased, for 150 m2 the power needed is approximately 25 kW.

What boiler do I need for 250 square meters?

The 38-45 KW condensing boilers are the best option for houses of approximately 250 to 350 square meters.

What power do I need to heat a room?

The ideal is to calculate between 80 and 100 watts per square meter of the room to be heated. That is, for a room of 10 square meters you need a thermal emitter of 1000 watts of power. Another aspect that must be taken into account is the time that you are going to have it working.

How many watts do I need to heat a room?

A good sizing rule is to calculate about 50 W per square meter to be heated. For example, a 750W electric radiator is enough to heat a 15mq room. However, the age of the property and the climatic zone should not be underestimated.

What power does the radiant floor need?

The operation of this type of radiant heating uses a power between 60-120 W/m2. Everything will depend on the size of the house and the insulation.

What boiler to put in a flat?

So which one to choose? The answer is that in homes of up to 100 m2 and a bathroom, 24KW for hot water and 24KW for heating. In homes of up to 180 m2 and two bathrooms, 28KW for hot water and 24KW for heating. In homes of up to 180 m2 with 3 bathrooms: 35KW for hot water and 28KW for heating.

What kind of boiler do I need for a three-story house?

We will have to take into account that if the house has 2 or 3 floors, this will be decisive for choosing a boiler with a little more power, for example 30 kW and up. If the house is between 200 m2 and 300 m2, we would have to start by looking at the powers from 30 kW to about 36 kW.

How many kW of diesel boiler do I need?

It is estimated that about 90 or 100 watts of power are needed for each square meter. So if your house were, for example, a single-family house of about 150 square meters, you would need about 13,500 watts of power.

How many watts does a gas boiler consume?

It is difficult to give a precise figure to say how much gas your boiler should consume, but you can use the size of your boiler to make an estimate. A 24 kW boiler will use 24 kW of energy per hour. If your boiler is on for a total of five hours a day, your daily consumption should be about 120 kWh.

How does aerothermal with underfloor heating work?

With Aerothermy, the operating principle of the heat pump is used, extracting energy from the outside air to transfer it inside, heating the water from the home’s heating circuit (underfloor heating, radiators, low-temperature radiators, fan-coils). ).

What is aerothermal heating?

AEROTHERMIA is a clean technology that extracts up to 77% of the environmental energy from the air for free. Aerothermal systems are state-of-the-art heat pumps designed to provide cooling in summer, heating in winter and, if desired, hot water all year round.

What are low temperature radiators?

As its name suggests, a low temperature radiator is a radiator that does not need a very high temperature to work. In fact, a low temperature radiator can work perfectly between 35º and 50º, while a cast iron radiator needs 80º and an aluminum radiator more than 60º.

What is cheaper pellets or aerothermal?

Biomass is the cheapest fuel on the market and pellet stoves represent a saving of 70% compared to natural gas. The aerotermia needs only 25% of electrical energy to work and has a coefficient of performance of 4.
