Maxiflame LK 551 HydroKit Solar M 3/4 thermostatic valves - for ACS

 

The LK 551 HydroKit Solar is a pre-assembled hydraulic kit consisting of thermostatic valves , designed for the management and optimisation of domestic hot water production in solar thermal systems.

Compact and ready to use, it integrates all mixing, diversion and safety functions in a single module, ensuring comfort, energy efficiency and system protection.

What it is and what it is used for

HydroKit Solar is a combination of thermostatic valves designed for systems with two heat sources (e.g. solar + boiler).

Its task is:

  • keep the water temperature constant
  • automatically manage the transition between solar source and integration
  • optimize the use of solar energy

Designed specifically for solar thermal ACS systems

How it works

The system integrates:

  • thermostatic mixing valve (35–65°C)
  • thermostatic diverter valve (42–52°C)
  • anti-scald function

In practice:

  • if the solar water is already hot → it is sent directly to the user
  • if it is not sufficient → it is diverted towards the integrative source

✔ Temperature stability ±3°C

Why it is advantageous

✔ Security

Prevents burns and protects the system from excessively high temperatures
✔ Integrated anti-scald protection

✔ Energy efficiency

Make the most of free solar heat

✔ Constant comfort

Water always at the set temperature

✔ Intelligent integration

Automatically manages the switch between solar and boiler

✔ Easy installation

Ready to use plug & play system

Installation

It is installed between:

  • solar boiler
  • sanitary network / boiler

✔ typical pattern:

  • collectors → boiler → HydroKit → utilities

✔ Quick and easy assembly, with connection kit included

Installation to be carried out according to regulations by qualified personnel.

Technical features

  • Connections: G 3/4 male
  • Mixing temperature: 35–65°C
  • Temperature deviation: 42–52°C
  • Max pressure: 10 bar
  • Operating temperature: 5–95°C
  • Temperature stability: ±3°C
  • Body material: CW617N brass
  • Fluids: water / water-glycol up to 50%
  • Kvs: 1.6 m³/h (code 181588)
  • Weight: about 1.6 kg

✔ Connection kit included (fittings, gaskets, check valves).

 

NB: FOR FURTHER TECHNICAL DETAILS WE RECOMMEND CONSULTING THE ATTACHED TECHNICAL DATA SHEET.

 

WARRANTY

The warranty is the official Maxiflame one and lasts 2 years.
