Home product catalogue

The range is organised into four main families that the company presents as a complete system, so that the different components work together to maximise energy efficiency.

• Heat pumps: aroTHERM plus, aroTHERM split and flexoTHERM models, plus the aroSTOR cylinder. The company presents the new aroTHERM plus as an evolution of its air source heat pump range.
• Gas boilers: combi, system and open vent boilers, with the ecoTEC plus (in a remastered version), ecoTEC exclusive, ecoTEC pro and ecoFIT pure ranges.
• Smart controls and thermostats: sensoCOMFORT, sensoHOME and sensoROOM pure, together with the myVAILLANT connect internet gateway.
• Hot water cylinders: uniSTOR range, in slimline and standard versions.

The company also offers hybrid configurations combining a heat pump and a boiler, and provides connectivity through the myVaillant app and smart home subscription services.

Technical service and maintenance

Vaillant UK provides after-sales support with its own network of 280 engineers who, according to the company, work 364 days a year. The service covers repair and maintenance for both boilers and heat pumps, annual appliance servicing, cover and care packages for heat pumps, guarantee registration and engineer visits. The annual service is presented as a way to maintain the guarantee, detect problems early and ensure the system operates safely and efficiently. The service can be booked online through the myVaillant Web portal.
