1) delivery and assembly based on the technical documentation possessed by the Employer 353 sets of solar collector installations for hot water production together with a structure adapted to the mounting location, including:

a) 153 sets (1 set consists of: 2 panels and a 200 dm container) 3 ) mounted on the roofs or walls of residential buildings of natural persons,

b) 47 sets (1 set consists of: 2 panels and a 200 dm container 3 ) mounted on the ground,

c) 107 sets (1 set consists of: 3 panels and a 300 dm container) 3 ) mounted on the roofs or walls of residential buildings of natural persons,

d) 33 sets (1 set consists of: 3 panels and a 300 dm container) 3 ) mounted on the ground,

e) 7 sets (1 set consists of: 4 panels and a 400 dm container 3 ) mounted on the roofs or walls of residential buildings of natural persons,

f) 6 sets (1 set consists of: 4 panels and a 400 dm tank 3 ) mounted on the ground,

2) disassembly of the existing hot water heater and disconnecting it from the installation,

3) installation of a new hot water heater together with a mixing valve and integration into the hot water system circuit,

4) assembly and insulation of pipelines between collectors, pump group and hot water heater,

5) assembly of the pump group,

6) installation of temperature sensors in solar collectors and in the tank,

7) connecting an existing heat source to the hot water heater,

8) flushing with solar fluid and carrying out leakage tests of the solar installation,

9) filling, venting and properly adjusting the liquid flow and determining the correct pressure according to the solar collector manufacturer's instructions,

10) finishing at least according to the original condition of the installation area (plaster, insulation, walls, ceilings, roof) and effective protection against atmospheric agents of places outside the facility where the works were carried out,

11) programming and commissioning of the automation system together with connecting a WLAN communication modem to the controller in order to read the parameters of energy yield via the Internet for 20 solar collector installations.

The controller saves daily monthly and annual energy accumulated by solar collectors on a microSD or SD card, and enables the transfer of stored information to a mobile external device. The controller or additional module for communication with the network has a built-in WiFi based on radio communication for wireless connection to the local existing network (WLAN),

And cooperation with the monitoring system.

12) execution, delivery and implementation of a renewable energy management system.

13) training the installation user in operating the devices used,

14) providing technical and commissioning documentation, operating instructions and general installation diagram,

15) other elements included in Annex 1a to the ToR and the contract template constituting Annex 2a to the ToR.

Supply and installation of biomass boilers in residential buildings in the Sitno Municipality, including, among others:

1) delivery and assembly based on technical documentation possessed by the Employer, 97 pcs. Biomass boilers in residential buildings, including:

a) 47 pcs. with a heating output of min. 15 kW

c) 11 items with a heating power of min. 24 kW

2) assembly of fittings, devices and other elements,

3) installation of the control system,

4) embedding the Ethernet module enabling the control of the preview functions of energy yield parameters via the Internet for 5 biomass boilers,

The controller saves the daily monthly and annual energy accumulated by the boilers on a microSD or SD card, and enables the transfer of saved information to a mobile external device. The controller or additional module for communication with the network has a built-in WiFi based on radio communication for wireless connection to the local existing network (WLAN) and cooperation with the monitoring system

5) execution, delivery and implementation of a renewable energy management system.

6) rinsing and pressure tests of the installation,

7) filling the installation,

8) starting the installation,

9) training Users,

10) preparation of the instruction manual and handing it over to the Users,

11) other elements included in Annex 1b to the ToR and the model contract constituting Annex 2b to the ToR.
