Ariston Genus ONE Net Combi Boiler

Ariston’s Genus ONE Net Combi is a highly reliable gas condensing boiler that pushes efficiency boundaries with its A+ energy rating. 

The Genus ONE Net Combi is the latest addition to Ariston’s ONE Series and comes in three sizes to suit your needs. This boiler is a compact, top-performing combi that combines elegant aesthetics, new materials and technological user interfaces to deliver a comfortable and trouble-free experience. Ideal for properties where space is limited, the Genus ONE Net is a space-saving solution that can help improve your home’s energy efficiency. 

How Much Does this Boiler Cost?

Available in 24kW, 30kW and 35kW outputs, the Ariston Genus ONE Net Combi will set you back anything between £1,050 and £2,100. The cost depends on which boiler size you require and does not include labour and installation costs. Boiler installation costs vary wildly, so it pays to get a quote from at least a few local and national installers. 

How will I know if this Boiler is Suitable for My Home?

The Genus ONE Net Combi range includes 24kW, 30kW and 35kW outputs, making it ideal for small, medium and large homes. Like all combi boilers, this appliance is a great space saver because it heats water directly from the mains and does not need a cold water tank or hot water cylinder. However, combi boilers are not generally suited to homes with an excessive need for hot water as they struggle to run two hot water taps at once. 

Before choosing the Ariston Genus ONE Net Combi, it’s worth consulting a qualified heating engineer for advice on the right boiler type and size for your home. 

Is it a High Efficiency Boiler?

Yep. The Ariston Genus ONE Net Combi is Boiler Plus ready straight out of the box and can achieve performances of up to A+ energy class, all thanks to the controls that come with it. Furthermore, this combi boiler boasts ONE condensing technology and thermoregulation accessories to enhance efficiency. 

Does this Boiler have a Good Range of Controls and Features?

All ONE series boilers from Ariston have a unique set of innovative smart functions and customisation options to make it easy for you to control your heating and hot water. Features include a ‘Comfort’ function, built-in W-Fi and digital timer programming, digital pressure gauge and an XtraTech stainless steel heat exchanger. The Ariston Genus ONE Net Combi also has an ‘Auto’ function that monitors the temperature of your heating system and adjusts the boiler operation accordingly to optimise energy efficiency. And when you download the Ariston NET app, you can manage your heating and hot water temperatures from your smartphone or PC. 

How long is the Warranty on this Boiler?

The Ariston Genus ONE Net Combi comes with a 12-year warranty as standard to give you peace of mind that your boiler is covered for more than a decade.
