Installation for White Rock Castle

White Rock Castle is located in Balchik town, on the coast of Black Sea. The elegant design, the panoramic view and the proximity to the Botanical Garden distinguished this suite hotel among others.

In 2015 in the hotel was opened spa, which need energy efficient heating and supplying of hot water. To complete the task, the hotel management chose the company NENCOM.

Our experts mounted pellet boiler, storage water heater, heating radiators, solar collectors and peripheral equipment.

The boiler Pelletherm V.2, with an output of 100 kW, is fitted with a convenient pellet hopper and it works in fully automatic mode: maintains set temperature, supply fuel in the combustion chamber and removes the ashes.

The cover of the hopper is equipped with comfortable locks

Hopper has a capacity of 100 kg and it has the ability to connect an additional reservoir

Mechanism for supplying of pellets and cleaning the combustion chamber

Near the pellet boiler is located SUNSYSTEM SON storage water heater with a capacity of 1000 liters with two heat exchangers: one is connected to the pellet boiler and the other — with the solar collectors.

Control of water temperature in the boiler (60 °C)

Control of the temperature in the coolant of the heat boiler (63 °C) and the solar collectors (94 °C)

To output the exhaust gases we installed ArtKamin chimney with stainless steel double-wall and insulation.

The length of the chimney is 18 metres

The exhaust gases are so clean that it is impossible to see them

In all rooms of the spa center we put heating radiators with regulators. To build 35 modules we used 430 ribs.

The main component of the system — solar collectors SUNSYSTEM Select — we put on the roof. Even in low sunlight they are easily heated the exchanger to 100 °C, providing with free hot water the spa.

Installation of solar collectors

The collectors are mounted at an angle of 33° and they are faced south
