Vaillant Spares

Vaillant have an impressive pedigree. They began making pumps in Remscheid Germany in 1874 and then gas boilers from 1894. A central heating system followed in 1924 and a combi boiler as early as 1967. They took over Glow Worm in 2001, and Vaillant's UK headquarters are still at the Glow Worm site in Belper Derbyshire. Today their range includes Vaillant heat pump systems and even geo-thermal boilers. Currently, Vaillant's most popular product line is ecoTEC. Newer models include ecoFIT, atmoTEC and turboTEC. Older models include the Unistor, UniFlow, Turbomax, Ecomax and VCW series. Many are still in good shape after years of service, as indeed are many Glow Worm models. They have a good reputation for heat efficiency and quiet running. Common problems include recurring low water pressure (a minor fault) and issues with the Vaillant pressure sensor or Vaillant diverter valve (like many combi boilers). We can supply OEM replacements for the Vaillant diverter valve and spares for the majority of Vaillant combi and system boilers, including Vaillant heat pump models. The following spares are usually available from us: the Vaillant diverter valve, pressure sensors, heat exchangers, PCBs, pumps, fans, gas valves, expansion vessels, timers, display boards, burners, flow sensors, connecting pipes, wiring, solenoids, service cocks, pressure switches and relief valves, gauges, electrodes, diaphragms, seals, spare knobs and pilot nozzles. If you have difficulty finding what you need, we are always happy to help.
