VXe Solo HWP (A247)

Application
The VXe Solo HWP (ECL 310 / A247 / A347) is a fully insulated substation for indirect heating with one heating circuit and primary connection for DHW cylinder featuring high performance and simple operation. VXe Solo HWP is especially suitable for two-pipe systems and systems such as systems with radiator or floor heating. Designed for wall-mounting with pipes connection in bottom. The heating circuit and the cylinder temperature is controlled by electronic temperature controller Danfoss ECL 310 / A247 / A347.

District heating (DH)
The substation is prefabricated with interconnecting components such as fitting piece and sensor pockets for insertion of a heat meter mounted in the DH return line, as well as strainer, thermometer and ball valves. The heating temperature is controlled by an electronic ECL 310 / A247 / A347 controller with weather compensation.
​​​​​​​
Heating (HE)
The heating side consists of a stainless steel plate heat exchanger and the VXe Solo HWP substation is available with heat exchanger type XB 06H-26, XB 06H-40 for radiator heating and type XB 06L-1 24 for floor heating. The heating side also features safety valve, expansion vessel, strainer, thermometers, manometer, energy-efficient circulation pump and ball valves. The HE circuit is controlled by the primary side pressure independent control valve with actuator AMV with or without safety function, the temperature by means of an electronic temperature controller ECL 310 / A247 / A347.

Mounting of heat meter
The substation is equipped with 3/4” fitting pieces in the DH return flow for fitting of a heat meter.
Domestic hot water
The VXe Solo HWP is supplied with connection pipes for domestic hot water cylinder on the primary side, and the temperature in the cylinder is controlled by a pressure independent control valve with actuator and Danfoss ECL controller.

Service and maintenance
The substation is very service-friendly and easy to install. It is mounted on the wall and as all pipes are placed in pipe bracket distance, it is possible to establish a nice piping. The removable cover plate in the front allows easy access to the specially designed chamber, where the most frequently used components such as ECL310 are located. The easy access chamber enables faster commissioning and maintenance without removing the whole cover of the substation.
