Baxi has always been active in the development of solutions which ensure the maximum environmental respect.

Baxi is also aware that next future’s heating solutions are based on the integration between boilers and systems

working with renewable energies.

Following this philosophy, Baxi has developed the

Principles of solar Energy

Sun energy: an opportunity to be exploited

Every object directly exposed to the sun absorb heat and increase its temperature. As a consequence of the

chemical reactions that take place in the mass of the sun, a constant stream of energy is produced as

electromagnetical radiation.

“solar constant” as the amount of incoming solar electromagnetic radiation per unit area, measured on

the outer surface of Earth's atmosphere in a plane perpendicular to the rays.

The solar constant includes all types of solar radiation (infrared rays, UV rays, etc.), not just the visible light. It is

is equivalent to 1.96 calories per minute per square centimeter, or 1.96 langleys (Ly) per minute.

As above stated, the Earth receives a total amount of radiation determined by its cross section but, as it rotates, this

energy is distributed across the entire surface area. Moreover, at any given moment, the amount of solar radiation

received at a certain location on the Earth's surface depends on the state of the atmosphere and the location's

latitude.

It’s possible to get electricity and heat from solar energy: a thermal solar system converts the solar radiation into

heated water to be used for home consumption. The thermal solar collectors are the devices able to perform this

conversion.

The inclination of solar collectors is the angle between the plane of their surface and the horizontal surface they rest

These collectors have multiple evacuated glass tubes which heat up solar absorbers and, ultimately, solar

, or

for hydronic space heating. The vacuum within the evacuated tubes reduce convection heat losses, allowing

their energy from the available light rather than outside temperature.

A claimed advantage

means that the collector is always perpendicular to the sun's rays and therefore the energy absorbed is

approximately constant over the course of a day.

Solar storage tanksThe power output of a solar system is not particularly high in comparison with standard heating systems. For

example, a 5 m² solar system can reach a maximum power of 2,5 kW while working under most favorable conditions.

Thus, the storage tanks is one of the most important components of the system since the sun gives his maximum

contribution only for few hours per day and not every day.

We can roughly state the tank capacity has to be 1,5-2 times the daily DHW demand. By increasing its capacity it

would be possible to store a bigger amount of energy but the inner temperature level would inevitably decrease (that

means the auxiliary boiler has to switch on much more frequently).

Generally, 200-400 litres double coil storage tanks are the best choice for single houses and apartments. Solar

circuit is connected to lower coil and auxiliary boiler to upper coil. The density difference between hot and cold water

inside the tank causes . Being lighter, hot water collects in the upper part of the storage

tank, whereas cold water collects in the bottom. The bigger is the ratio between height and diameter, the more the

temperatures stratify.

even in case of scarce

solar irradiation.

The storage tank must be very well insulated. Thermal losses amount should be as low as possible. For example,

the coil shouldn’t be higher than 15 K.

Regulation accessoriesfor forced draft installationControllers

the right room temperature as well as measuring the spoiled energy.

This goal can be reached through simple and compact controllers, which receive signals from various elements and

allow to set the control temperature, the timings for switching on auxiliary boilers, etc.

The controllers

real solar energy power support; it measures the

temperature out of the collector and in the bottom of the tank through sensors. The differential thermostat compares

both temperatures and in case the temperature is higher than the set limit, the circulating pump starts working.

Apart from what explained above, the controller can be adopted in different points and for many uses inside these

types of installation.

Features:

Digital temperature regulation

2 sensors that can be linked

Protection of the collector against over temperatures

Display of the anomalies and memory of all the set parameters set also

in case of long electrical power interruption

Display of the instantaneous temperatures of the collector or of the ranks

and of the linked cylinders

thanks to a simple display, with only 4 buttons, of the system’s working.

The “Comfort” controller grants a perfect regulation of solar systems installation made also by 2 banks of collectors

or 2 storage tanks. It can be used also on a traditional solar installation, as well as in the 4 installation schemes.

Solar kit

Baxi solar kit has been developed to be connected to the range of

the instantaneous gas boilers. It represents a compact solution which

includes adjustable thermostatic mixing valve and diverter valve. If the

temperature of the water warmed by the solar system does not reach

the desired level of comfort, the diverter valve makes the boiler to

intervene to supply DHW at the desired temperature.
