Frequently Asked Questions

• Are these older Vaillant boilers still available? Yes, this is the previous, but still sold and serviced, generation of ecoTEC boilers, not discontinued models.
• What does instantaneous hot water heating mean? The boiler heats hot water directly as it is drawn (instantaneously), without the need for a separate storage tank – suitable especially for smaller households with lower hot water consumption.
