Wall-mounted gas double-circuit boilers Protherm Gepard with a capacity of 12 and 23 kW for heating and hot water preparation in a stainless steel plate heat exchanger.

Technical features:

• Reliable, copper heat exchanger.

• Bright LCD display.

• Coaxial chimney.

• Robust stainless steel secondary heat exchanger.

• Composite hydraulic block.

Using the liquid crystal display, you can continuously receive information at any time during the operation of the boiler. The display allows you to constantly monitor the entire process.

Models 11 MTV and 23 MTV can be equipped with a coaxial exhaust gas system and do not require connection to a chimney, which allows them to be installed in rooms where there is no stationary chimney or its installation is very difficult or impossible due to various reasons.

Switching to DHW mode occurs automatically when the hot water tap is opened. The main feature of the boiler is the rapid heating of water, about 2 seconds.

The reliability and durability of the boiler is ensured by a hydraulic block made of durable composite material. The copper heat exchanger and burner made of chromium-nickel steel, the plate secondary heat exchanger made of stainless steel once again emphasize the quality of the boiler.

The new SIT pneumatic gas valve is quieter than the previous generation gas valve.
