Laddomat 21-100: Efficient boiler filling and temperature control

Fast heating and optimal temperature stratification

The Laddomat 21-100 ensures that your boiler reaches its ideal operating temperature in the shortest possible time. It then charges the heating water tank at a consistently high temperature and low flow rate to ensure the desired temperature stratification.

This controlled filling maintains the stratification in the storage tank, which leads to a consistently high efficiency of your heating system and saves fuel.

Corrosion protection and extended service life

By increasing the return temperature to the bottom of the boiler, the Laddomat 21-100 effectively prevents corrosion and tar formation. This protective measure contributes significantly to increasing the service life of your boiler.

This means you benefit from longer maintenance intervals and lower maintenance costs for your heating technology.

Efficient loading with thermal valve

During the final firing phase, the integrated thermal valve completely closes the bypass port, ensuring perfect and complete filling of the tank.

The result is almost complete utilization of the generated heat energy, making your system even more economical.

Use of residual heat and self-circulating function

After combustion, the Laddomat 21-100 optimally utilizes the residual heat stored in the boiler and annealing bed. An integrated self-circulation system automatically returns the hot water to the storage tank – even in the event of a power outage.

This ensures that your heating system remains efficient and reliable even under critical conditions.

Robust construction and easy installation

The Laddomat 21-100 impresses with its clear and stable design and durable sealing surfaces. Installation is quick and easy, benefiting both installers and DIY enthusiasts.

Solid workmanship guarantees long-term reliable function and minimizes the risk of leaks or wear.

Ease of use thanks to interchangeable ball valves

Replaceable Teflon packing boxes and heavy-duty metal levers make the ball valves particularly easy to handle. This allows all service work to be carried out quickly without having to completely drain the system.

The valves are easily accessible and ensure permanent tightness and smooth operation.

Generous throughput and EPP insulation

Our specially designed ball valves offer extra-large flow rates to ensure maximum water flow even during the final stages of the charging process and during self-circulation.

The standard EPP insulation minimizes heat loss and also contributes to the energy efficiency of your heating system.
