Floorstanding DHW cylinders

SE-2, SEM & SEW

The WOLF SE-2, SEM and SEW floorstanding cylinders are ideal storage cylinders for efficient DHW heating in your home.

The right DHW cylinder for any heating system

SE-2 floorstanding cylinder

The SE-2 is the classic DHW cylinder for WOLF gas or oil heating systems. It is available in the versions SE-2-150, SE-2-200, SE-2-300 SE-2-400 SE-2-500 and SE-2-750.

You are sure to find the right model amongst these six sizes ranging from 150 to 750 litres, whether you have a detached house or an apartment building.

SEM-1 & SEM-2 solar floorstanding cylinders

The WOLF SEM-2 is available in the versions SEM-2-300 and SEM-2-400 for solar thermal systems in detached homes.

The SEM-1 is a solar floorstanding cylinder that integrates the solar thermal technology of an apartment building into the heating system. Three solar cylinder variants – the SEM-1-500, SEM-1-750 and SEM-1-1000 – allow you to choose the perfect cylinder volume depending on the number of flats and residents in the building.

The special SEM-1-360 version is the perfect combination of a solar thermal system and heat pump.

SEW-1 & SEW-2 heat pump floorstanding cylinders

SEW-1 and SEW-2 are special storage cylinders for DHW heating in connection with heat pumps.

Benefits of WOLF floorstanding cylinders

DHW cylinders lower heating costs

Reduced load on the heating system

The freestanding cylinder relieves the load on your heating system because it doesn't have to switch on every time you need hot water.

Properly sized heating system

A heating system with a floorstanding cylinder consumes less power than a heating system without a cylinder. This means that inefficient and oversized heating systems are a thing of the past.

Many years of service

Lower wear on heating system components

A WOLF floorstanding cylinder reduces the number of burner starts in oil and gas boilers. The result: reduced wear and extended service life of the heating system.

Corrosion protection

The floorstanding cylinder itself is also very durable thanks to state-of-the-art corrosion protection.

Precise coordination

Suitable for any heating system

Other DHW cylinders are better suited to solar thermal systems than to heat pumps. There is a WOLF freestanding cylinder for every heat generator.

Well-coordinated complete system

All WOLF system modules are coordinated and complement each other to form a complete, unified system.

Perfectly in tune with you.

Always an ample supply in your DHW cylinder

Outstanding insulation means there will always be an ample supply in your cylinder even if you use large amounts of hot water. WOLF freestanding cylinders can also produce an abundant supply of hot water as and when required thanks to the generously sized heat exchangers.
