Ariston GENUS ONE NET 35 Combi Gas boiler frequently asked questions

What type of boiler is Ariston’s GENUS ONE NET 35 - system, regular or combi?

The Ariston GENUS ONE NET 35 boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

Combi boilers were introduced by manufacturers in the 1970s to offer British homeowners a way to cheaply and reliably heat their homes and have hot water without taking up too much space. Previously, most boilers had one or more storage tanks, which either heated water and kept it warm or held water to be heated later.

With combi boilers, there is no need to find space for large tanks around your home as the hot water needed for your radiators and taps is available on demand. Combi boilers do this by drawing water from your mains supply, heating it instantly whenever you need it and then distributing it to where it's needed in the home.

The major disadvantage to combi boilers is that they have a maximum capacity for heating water. In a larger household, water pressure, volume and temperature will drop if two or more people are trying to use hot water at the same time.

Is a Ariston GENUS ONE NET 35 combi boiler suitable for my house or flat?

Selecting the right boiler for your property means selecting a boiler that is the right size. And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

The output of the Ariston GENUS ONE NET 35 combi is 31 kW kilowatts, so which types of property would this be appropriate for?

Most experienced Gas Safe boiler installers would recommend that a boiler with this output level would be most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

You also need to choose a combi boiler with the right flow rate for where you live.

A combi boiler's flow rate is the maximum volume of water (measured in litres per minute) that it can heat and distribute to your radiators, taps and showers at the same time. This Ariston GENUS ONE NET 35 Combi boiler's flow rate is 14 L/m.

However, combi boilers like the Ariston GENUS ONE NET 35 draw water directly from the mains and heat it instantly.

If your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate.

Combi boilers also struggle when multiple people in your home want to use hot water at the same time - for example, someone running the hot water tap in the kitchen and two people wanting to shower in separate bathrooms.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


What are the dimensions of the Ariston GENUS ONE NET 35 boiler?

The Ariston GENUS ONE NET 35 has the following dimensions - TBC mm high, TBC mm wide, and TBC mm deep.

GENUS ONE NET 35 – non-condensing or condensing?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Ariston GENUS ONE NET 35.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

Is the Ariston GENUS ONE NET 35 combi rated as environmentally friendly?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

In the largest cities of Britain, gas boilers are responsible for dangerous levels of atmospheric nitrogen dioxide emissions. In total, 14% of the UK’s greenhouse gases are produced by central heating systems.

Would choosing the Ariston GENUS ONE NET 35 combi be an environmentally-friendly choice? If so, let's look at its performance figures.

All boilers manufactured after April 2018 in the UK must be rated as an “A” on the SEDBUK grading system, subject to a minimum energy efficiency rating of 92% or above. Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Ariston GENUS ONE NET 35 has an efficiency rating of 90.1% with a SEDBUK grade of "A".

The ERP (Energy Related Products Directive) is European legislation that aims to reduce the use of energy at all points during a product's life, from the point of manufacture to when it's in active use right through to final disposal.

The regulation aims is to encourage manufacturers to create products that are more environmentally friendly and which reduce the harmful gas emissions associated with those products.

The ERP gradings for the Ariston GENUS ONE NET 35 are "A" for heat and "A" for hot water.

What is the length of the warranty on the Ariston GENUS ONE NET 35?

The Ariston GENUS ONE NET 35 boiler is provided with a parts and labour warranty lasting 12 years.

Ariston GENUS ONE NET 35 Combi Gas boiler frequently asked questions

Is the Ariston GENUS ONE NET 35 a combi, system or regular boiler?

The Ariston GENUS ONE NET 35 is a combi boiler you may wish to consider if you want this particular type of boiler for your house or flat.

Combination or combi boilers are highly efficient and save a lot of space in your home. Combi boilers heat water directly from the mains when you turn on a tap and, as a result, you don’t need a hot water storage cylinder or a cold water tank in the roof space.

These boilers are, therefore, suitable for smaller homes and especially those without a loft. They are also cost-effective as the water is heated instantly and distributed on demand rather than being stored. Combi boilers are the most popular type of boilers in the UK and replacing an older boiler with a new combi boiler will reduce your gas bills significantly.

However, there are downsides to this type of boiler. If you take a shower while someone else is using a tap, less water will reach each point of usage at lower rates of pressure and temperatures as combi boilers can only heat a certain volume of water at any given time.

Should I choose a Ariston GENUS ONE NET 35 combi boiler for my house or flat?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.

The Ariston GENUS ONE NET 35 combi boiler has an output of 31 kW, so which types of property would it be most appropriate for?

An experienced boiler engineer would recommend that this Ariston GENUS ONE NET 35 Combi boiler would provide adequate heating and hot water for medium-sized homes and larger apartments with up to 10-15 radiators and two bathrooms.

You should also consider a combi boiler's "flow rate" when making your choice.

The flow rate indicates how much water it can take from the mains supply at any one time (measured in litres per minute), which it then heats and distributes to different points in your home like your bathroom, kitchen and radiators. This Ariston GENUS ONE NET 35 Combi boiler's flow rate is 14 L/m.

Combi boilers have no storage tanks like system or heat only boilers. This means that if the water pressure where you live is low, there's no benefit in spending money on a combi with a high flow rate because a high flow rate doesn't mean it can draw any more water from the mains.

In addition, there might be lots of people in your household who want to use hot water at the same time while also having the central heating on. Given that average mains pressure in the UK is between 10 and 12 litres per second and a power shower usually requires about 12 litres of water per minute, a combi boiler might not be the right choice for you and your family.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


Ariston GENUS ONE NET 35 - size in millimetres

The size of the Ariston GENUS ONE NET 35 boiler is TBC mm tall, TBC mm wide, and TBC mm deep.

Ariston GENUS ONE NET 35 – non-condensing or condensing?

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Ariston GENUS ONE NET 35 are more efficient with the gas they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns gas to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

Is the Ariston GENUS ONE NET 35 combi considered environmentally friendly?

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Will installing a Ariston GENUS ONE NET 35 combi in your home be a positive contribution to the environment? The figures below will tell you more.

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

Following testing, the Ariston GENUS ONE NET 35 was given an efficiency rating of 90.1% and a SEDBUK grading of "A".

In 2015, new legislation was introduced by the EU to encourage manufacturers to develop more energy-efficient products that emit fewer harmful gases throughout their lifetime.

The Energy Related Products Directive (ERP) applies to all products that consume energy, including during the manufacturing process, at the point of final disposal, and all points in between.

The ERP rating of the Ariston GENUS ONE NET 35 is "A" for heat and "A" for hot water.

What warranty do I get if I purchase the Ariston GENUS ONE NET 35 boiler?

Ariston’s GENUS ONE NET 35 boiler includes a parts and labour warranty of 12 years.
