Ariston GENUS ONE NET 35 Combi Gas boiler frequently asked questions

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

The Ariston GENUS ONE NET 35 may be worth considering if you are looking for a combi boiler for your house or flat.

Traditional boilers often have up to two tanks that either store heated water or water to be heated later. Boiler manufacturers introduced combi boilers in the 1970s to avoid the need for those big tanks. Combi boilers allow homeowners to benefit from the reliable central heating and hot water level they want but without having to give up so much space within their properties - remember that homes in the UK are among the smallest in the developed world.

Your taps and radiators get the hot water they need with a combi boiler. Combi boilers draw cold water direct from the mains which is then heated instantly on demand and distributed to your radiators and taps.

However, combi boilers cannot heat very large volumes of water, which is their main disadvantage. So, for example, when someone wants to take a shower while another person wants to use a hot water tap to do the dishes, water pressure and quantity to both points decreases.

Should I install a Ariston GENUS ONE NET 35 combi boiler in my house or apartment?

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.

With all combi boilers, the "flow rate" (measured in litres per minute) is as important a consideration as output rate when choosing which model to go for. This Ariston GENUS ONE NET 35 Combi boiler's flow rate is 14 L/m.

Like all combi boilers, the Ariston GENUS ONE NET 35 draws water from the mains. It instantly heats that water and then distributes it to the parts of your home which need it - taps, radiators, bathrooms, and so on.

However, the water in the mains pipe that feeds your boilers has its own flow rate - normally between 10 and 12l/m. So if you choose a combi with a flow rate of 14l/m but local water pressure is equivalent to 11l/m, your boiler will actually operate at 11l/m - below its capacity.

In addition, if different family members want hot water at the same time (like for regular morning and evening showers) and your boiler has to provide hot water to your radiators at the same time, a combi boiler may not be suitable.

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 size is the Ariston GENUS ONE NET 35 boiler?

The Ariston GENUS ONE NET 35 is TBC mm in height, TBC mm in width and TBC mm in depth.

Is the Ariston GENUS ONE NET 35 non-condensing or condensing?

We recommend that, if possible, you choose a condensing boiler like the Ariston GENUS ONE NET 35.

Condensing boilers are more energy-efficient. They achieve this efficiency by capturing the heat present in flue exhaust gases and water vapour condensation and recycling that heat to, for example, warm colder water coming back from your radiators.

By choosing the latest condensing boiler, you'll also notice a significant reduction in your gas bills, particularly if you're replacing a boiler more than 15 years old.

Is the Ariston GENUS ONE NET 35 combi environmentally friendly?

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

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.

Is the Ariston GENUS ONE NET 35 combi boiler an environmentally friendly choice for your home? Here’s what the figures say.

By law, the minimum level of energy efficiency for boilers manufactured in the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

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

The Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

For the Ariston GENUS ONE NET 35, the ERP Heat rating is "A" and the ERP Water rating is "A".

How long is the warranty offered by the manufacturer for the Ariston GENUS ONE NET 35 boiler?

The Ariston GENUS ONE NET 35 boiler is covered by a parts and labour warranty of 12 years.

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?

Ariston’s GENUS ONE NET 35 is one you might consider if you’re looking for a combi boiler for your house or flat.

Traditional boilers have one or two tanks - one holds hot water to keep it warm and the other water for later heating. Because UK residential property is among some of the smallest in the world, manufacturers introduced combi boilers and the heat pumps that go in them in the 1970s to reduce the amount of space boilers needed to take up.

The hot water needed for your radiators and taps is available on demand when you have a combi boiler. Combi boilers use technology located within the boiler to heat cold water, which it draws from the mains, and to distribute hot water where it's needed around your home.

A combi boiler, however, has the disadvantage of a maximum capacity for the amount of water it can heat. The result is that if someone uses the shower while another uses a hot water tap simultaneously, the amount of water reaching each point falls, causing water pressure to drop.

Is the Ariston GENUS ONE NET 35 combi boiler a suitable choice for my property?

Selecting the right boiler for your home means choosing 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".

Your boiler’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your gas than you need to.

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

Most heating engineers would recommend this Ariston GENUS ONE NET 35 Combi boiler as a suitable option 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.


How big is the Ariston GENUS ONE NET 35?

The Ariston GENUS ONE NET 35 measures TBC mm in height and has a width of TBC mm and a depth of TBC mm.

Is the Ariston GENUS ONE NET 35 condensing or non-condensing?

Because of their increased energy efficiency, we recommend to all customers that they select one of the latest condensing boilers. Condensing boilers capture the heat from water vapour condensation and flue exhaust gases and recycle that heat to warm water entering the boiler (for example, from your radiators).

The Ariston GENUS ONE NET 35 is a condensing gas boiler and choosing this model will result in a likely substantial reduction in your fuel bills, particularly if you're replacing an older, inefficient, non-condensing boiler.

Does the Ariston GENUS ONE NET 35 combi protect the environment?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Is the Ariston GENUS ONE NET 35 combi an environmentally friendly choice for your home? Let’s have a look at the figures.

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Ariston GENUS ONE NET 35 is rated as 90.1% energy efficient, equivalent to a "A" SEDBUK rating.

The Energy Related Products Directive grades products according to the energy they consume and the harmful gas emissions they create, from manufacturing right through to final disposal, including how they're used by customers between these two points.

The Ariston GENUS ONE NET 35 is rated "A" for heat and "A" for water.

If the Ariston GENUS ONE NET 35 breaks down, will I be covered by the warranty?

The Ariston GENUS ONE NET 35 is supplied with a parts and labour warranty of 12 years.
