Vaillant has three ranges of standard efficiency boilers. The first is the pioneering new aquaPLUS combination boiler with integrated power store. Thanks to the 15-litre stainless steel store the boiler delivers outstanding bath filling and shower performance, supplying over 170 litres of hot water (delta T 35°C) in 10 minutes.

  

The turboMAX plus range of high specification combination boilers incorporates a comprehensive collection of features, including an advanced ‘AquaComfort’ system that delivers instantaneous hot water through the Warmstart facility, and ensures constant water temperatures, even at reduced flow rates. There are three models in the range with 24, 28 and 37kW outputs.

  

There are three boilers in the thermoCOMPACT range of standard efficiency system boilers with modulating outputs of up to 15kW, 28kW and 37kW respectively. thermoCOMPACT boilers boast a host of built in features including an expansion vessel, automatic bypass, air vent, circulation pump and 2-stage frost thermostat.
