Code 4.101
System with traditional boiler, domestic hot water production and storage with solar integration

The system can be divided into 4 zones:

Boiler zone

The boiler zone essentially consists of a floor-standing boiler fitted with the following components:

·       High efficiency circulation pump

·       Expansion vessel and safety relief valve

·       Regulation and safety thermostats

·       Temperature gauges and pressure regulation indicators

·       Charging unit

Heating system zone

·       Manifold/separator with 2 outlets

·       Thermostatic regulating units

·       Distribution manifolds at the radiators

·       Radiators: radiant panels and towel warmers or decorative radiators at low temperature

The boiler temperature must be subject to set point temperature regulation.
The heating medium is sent to the 2 specified levels by means of 2 thermostatic regulating units serving the zone thermostats.

Solar panels zone

This zone is essentially composed of:

·       Flat manifold or vacuum pipe type solar panels

·       1 circulation unit for solar thermal systems with pump and shut-off, control, expansion and safety equipment

·       1 solar circuit control unit with corresponding temperature probes

·       1 solar type tank for domestic hot water production and storage

Domestic hot water production and distribution zone

Domestic hot water is produced in the solar tank with the support of the hot medium produced by the boiler.
The anticipated distribution system does not feature recirculation and is equipped with a thermostatic mixing valve.

Note:
The control, expansion and safety equipment must be of appropriate size to reflect the heating capacity and specific characteristics of the system, in accordance with applicable laws and regulations.

The system must be created in observance of any relevant regulations and specifications.
