Main Features

The water-based energy fireplaces are designed to connect to the home's radiator network, offering the possibility of completely eliminating and replacing any other heating system, such as an oil boiler, etc. The main features of Werstahl hydro fireplaces are as follows:

  • Hydraulic connection to the home's central heating system.
  • Easy manual adjustment of primary air intake.
  • Vertical airflow in front of the glass, which reduces blackening from smoke (tertiary combustion).
  • Secondary combustion, which takes place at the back of the fireplace, increasing its efficiency by providing additional oxygen to the fire immediately after primary combustion.
  • Reliable and durable chain system for upward door opening, German-made, with completely silent operation and a long lifespan.
  • Eco-friendly paint, specially designed for energy fireplaces, odorless, and resistant up to 600oC.
  • Ceramic glass door resistant to temperatures up to 750oC.
  • Plastic wheels for easy transportation to the installation site.
  • Chimney damper for easy manual adjustment of smoke flow and fire intensity.

  • The weight of a fireplace and its pressure resistance are indicative of its sturdiness and lifespan.
  • The higher the efficiency rating of a fireplace, the more economical it is in wood consumption.
  • The useful power output of a fireplace is calculated only by multiplying the nominal power by the efficiency rate (e.g., 40kw x 80% = 32kw useful power output). Any other statement such as "the fireplace delivers all its power to the water" is incorrect and misleading.
  • If the wire rope breaks, the entire fireplace cladding must be dismantled for repairs. The chain never breaks.
  • The larger the water tank capacity of a fireplace, the more efficient and effective its operation.
  • The larger the heating surface of a fireplace, the greater its efficiency and, consequently, the more economical its wood consumption.

Never choose a fireplace based on the square meters of your home. Make your selection solely based on the calories of your heating radiators, with an increase of 20-30%.

For example, if the total sum of all radiator calories in your home is 20,000 calories, then the required fireplace power should be:

20,000 x 1.30 = 26,000 calories / 0.86(?) / 1000 = 30.23 kW.

Hydraulic Connection Kit

Connection to a closed circuit

Closed circuits with a sealed expansion tank in energy fireplaces that supply radiator systems offer significant advantages over open systems. Specifically, they prevent water and air losses, reduce the corrosion of metal surfaces, maintain stable pressure and temperature, and enhance safety through valves that prevent overpressure.

Additionally, they improve efficiency and cost-effectiveness, provide flexibility in installation, reduce the risk of freezing, and contribute to better aesthetics and cleanliness of the space. Overall, they are an efficient and safe heating solution.

Image
Image

Connection to an open circuit

The open circuit with an open expansion tank in energy fireplaces operates with direct contact between the water and the atmosphere, allowing natural expansion and pressure relief. Although it offers simplicity and lower initial installation costs, it has increased losses due to evaporation and a higher risk of corrosion. The pressure remains close to atmospheric, reducing the risk of overpressure, while the natural flow can ensure operation even without electricity. However, it requires more frequent maintenance and water refilling.

The choice depends on the installation requirements and the user's priorities.

Connection with a heat exchanger

The circuit with a heat exchanger combines both open and closed loops, allowing the energy fireplace to operate with an open expansion tank while the radiators function within a closed circuit. The heat exchanger hydraulically separates the two circuits, reducing corrosion in the closed system and ensuring stable pressure and performance.

It provides enhanced safety, protection against overheating, and installation flexibility while allowing natural flow in the open circuit and reduced maintenance costs in the closed one. Overall, it is an efficient solution that effectively utilizes the fireplace's heat, offering the benefits of a modern heating system.
