There are three groups of Vaillant boilers for on demand
(tankless)
water heating and a group of Vaillant cylinders:

High efficiency combi boilers
System boilers
Open vent boilers
Cylinders

vaillant boilers - ecotec series Vaillant
combi
boilers are actually tankless water heaters (as known in
US) that are the most popular and selling type of all Vaillant boilers.
Vaillant combination boilers are
high efficiency units that are working on demand, to heat home
and domestic water, and they do not need a separate water storage tank.

Combi
boilers are gas powered that are providing hot water whenever hot water
tap is open and modulating gas burner through the intelligent
electronics adjusts its power to meet the demand for central heating.

The
most popular high efficiency combination boilers are Vaillant
ecoTEC exclusive, Vaillant
ecoTEC plus
and
Vaillant ecoTEC pro,
all of them
wall mounted, with room-sealed combustion and fan assisted, offering
different
capacity. The most popular boiler sizes are 24 and 28 kW.

System
boilers, known as sealed system boilers
require a storage cylinder to provide
central heating and hot water. When they work with the unvented hot
water cylinder they do not require cold water storage tank. System
boilers are represented by the ecoTEC
plus
model.

Open vent boilers,
usually have two tanks and hot water storage so they can provide
central heating and hot water. They can also be used with the
sealed boiler.

The last two systems are designed to deliver high volumes of
hot water
and for multiple outlets.

From
2005 it is a law in UK that all combi boilers should be high efficiency
or condensing boilers. These high efficient boilers are using the flue
heat for additional water heating, which results in increasing the
energy efficiency to over 90%, making them more efficient than
conventional boilers.
