Why Choose the Viessmann Vitodens 100-W Open Vent 19kw

The Viessmann Vitodens 100-W Open Vent 19kW continues the tradition of German engineering excellence, offering a robust and efficient heating solution for homes with open vent systems.

Ideal for medium-sized properties or households that need a bit more heating power, the 19kW output delivers consistent warmth and hot water when paired with a separate cylinder. It’s a great step up for anyone upgrading from an older boiler. If your home requires even more heating performance, it’s worth looking at the Viessmann Vitodens 100-W Open Vent 32kW, which offers added capacity without compromising on efficiency.

This model features Viessmann’s signature stainless steel heat exchanger for exceptional durability and heat transfer. Its compact, tidy design fits easily into standard cupboards or loft spaces, and the near-silent operation makes it a discreet addition to the home.

The intuitive digital controls make temperature adjustments simple and accessible, with clear diagnostics to support easy servicing.

With a manufacturer-backed warranty of up to 10 years, the Vitodens 100-W stands out for its long-term reliability and trusted performance.

For homeowners who want a quiet, efficient, and future-ready boiler, the 19kW model is a solid investment. And for those with larger heating demands, the 32kW version is well worth considering.

Our engineers review of the Viessmann Vitodens 100-W Open Vent 19kw

“I’ve just installed the Viessmann Vitodens 100-W Open Vent 19kW in a semi-detached property, and it’s been spot on. It’s well built, runs quietly, and delivers enough heat for a medium-sized home without changing too much of the existing central heating system.

The stainless steel heat exchanger gives it solid reliability, and the controls are nice and straightforward, no confusion for the homeowner. It’s a great step up from the 16kW, and I’d definitely fit it again. For bigger heating loads, I’d point customers toward the 32kW version.”

What is the total maximum horizontal flue length?

10 metres minus any flue kit options or bends

What is the total maximum vertical flue length?

10 Metres – minus any bends

What should be deducted off the total flue length for each 90 degree flue bend?

1 metre needs to be deducted off the total flue length.

Example, if there are 3 x 90 degree flue bends needed for the installation, the maximum horizontal flue length would be reduced to 7 metres and 7 metres in total for vertical flue installations.

What should be deducted off the total flue length for each 45 degree flue bend?

0.5 metres needs to be deducted off the total flue length.

Example, if there are 4 x 45 degree flue bends needed for the installation, the maximum horizontal flue length would be reduced to 8.5 metres and 8.5 metres in total for vertical flue installations.
