Laddomat 21-100: Efficient boiler filling and temperature control

Rapid heating and optimal temperature stratification

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

This controlled filling process maintains the stratification in the storage tank, resulting in consistently high efficiency of your heating system and saving 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 buildup. This protective measure significantly contributes to extending the service life of your boiler.

This allows you to benefit from longer maintenance intervals and reduced effort in maintaining your heating technology.

Efficient loading with thermostatic valve

During the final combustion phase, the integrated thermostatic valve completely closes the bypass port. This ensures perfect and complete filling of the tank.

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

Use of residual heat and self-circulating function

After the combustion process, the Laddomat 21-100 optimally utilizes the residual heat stored in the boiler and glowing 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 assembly

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

Solid workmanship guarantees permanently reliable function and minimizes the risk of leaks or wear.

Ease of use thanks to interchangeable ball valves

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

The valves are easily accessible and ensure a permanent seal as well as smooth operation.

High throughput and EPP insulation

Our specially developed ball valves offer an extra large flow rate to ensure maximum water flow even in the final stage 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.
