Ariston ALTEAS ONE NET 30 Combi Gas boiler frequently asked questions

What kind of boiler is the Ariston ALTEAS ONE NET 30 - standard, combi or system?

If you’re looking for a combi boiler for your house or flat, then the Ariston ALTEAS ONE NET 30 is one you may wish to consider.

Traditional boilers need one or more large tanks to work - one to heat and keep water warm for immediate use and the other to store water intended for heating later. Finding space for these large tanks is difficult in British residential property - remember that our houses and flats are among the smallest in the world. This is the problem that combi boilers were designed to solve when they were introduced in the 1970s.

Combi boilers don't need a tank - instead, they instantly heat water drawn from the mains using technology inside the boiler. This hot water is then distributed immediately to your taps or radiators on demand.

The biggest disadvantage to combi boilers is that they have a maximum capacity for heating water, meaning that they work best when only one point within a household wants hot water. For example, if someone is taking a shower and another person uses a hot water tap at the same time, the water pressure, volume and temperature to both points drops.

Is the Ariston ALTEAS ONE NET 30 combi 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 ALTEAS ONE NET 30 combi is 28 kW kilowatts, so which types of property would this be appropriate for?

An experienced heating engineer would recommend that the Ariston ALTEAS ONE NET 30 combi boiler is a suitable choice for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

With combi boilers like the Ariston ALTEAS ONE NET 30, you need to take the flow rate into account as well as the output rate.

Combi boilers draw water from the mains and then instantly heat that water and send it to wherever in your home it's needed. Flow rates, measured in litres per minute, are subject to the mains water pressure in your area. So, for example, if the local mains water pressure is 11 litres per minute and the flow rate of your boiler is 14 litres per minute, the boiler will not be able to process more than 11 litres per minute. The flow rate of this Ariston ALTEAS ONE NET 30 Combi boiler is 12 L/m.

If you live in a home with lots of radiators or bathrooms where many people want to use hot water at the same time, a combi boiler may not be able to cope. For reference, a power shower uses about 10 litres of water per minute. If two people want showers at the same time or one person wants a shower and the other hot water from a tap in the kitchen, your boiler may not have a large enough flow rate even if the local mains water pressure is high.

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.


The size of the Ariston ALTEAS ONE NET 30 in millimetres

The size of the Ariston ALTEAS ONE NET 30 boiler is TBC mm tall, TBC mm wide, and TBC mm deep.

Is the Ariston ALTEAS ONE NET 30 a condensing or non-condensing boiler?

The Ariston ALTEAS ONE NET 30 is a condensing gas boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

Is the Ariston ALTEAS ONE NET 30 combi a good choice for the environment?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Let's take a closer look at whether installing a Ariston ALTEAS ONE NET 30 combi would be a good choice for the environment.

The Ariston ALTEAS ONE NET 30 has been awarded an efficiency rating of 94% and a SEDBUK band rating of "A".

In the UK, all boilers manufactured and supplied must have an energy efficiency rating of at least 92% or a SEDBUK "A" grade. Until April 2018, the minimum rating was 88% (88% and 89% are equivalent to a SEDBUK "B" rating and anything higher is rated "A").

A boiler's energy efficiency rating describes the amount of energy it uses and wastes when in normal operation.

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 ALTEAS ONE NET 30 is "A" for heat and "A" for hot water.

Ariston ALTEAS ONE NET 30 Combi Gas boiler frequently asked questions

Ariston ALTEAS ONE NET 30 - combi, system or regular boiler?

The Ariston ALTEAS ONE NET 30 is a gas combi boiler.

Traditional boilers consist of one or more large tanks that take up a lot of space in people's homes. One tank heats water and keeps it warm and the other stores water for heating later.

In contrast, a combi boiler is a much smaller stand-alone unit. Instead of requiring water tanks, it draws cold water from the mains. When hot water is needed for a shower, for the washing up, or the dishwasher, the cold water is heated instantly by the boiler and distributed to where it is needed.

The main disadvantage of combi boilers is that there is a limit to how much water they are capable of heating at the same time. For instance, water pressure, volume and temperature will be adversely affected if more than one individual in the home needs hot water at the same time.

Would the Ariston ALTEAS ONE NET 30 combi boiler be suitable for my house or flat?

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 ALTEAS ONE NET 30 combi has an output of 28 kW, so which types of property would this Ariston ALTEAS ONE NET 30 Combi boiler be appropriate for?

An experienced PlumbProud heating engineer would recommend that the most suitable type of property for a Ariston ALTEAS ONE NET 30 combi would be medium-sized homes and larger apartments containing 10-15 radiators and providing hot water for two bathrooms.

In addition to the output rate, you should consider a boiler's "flow rate" (measured in litres per minute) when choosing a combi boiler.

If you have a lot of radiators and bathrooms in your home and members of your household want to use hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate. This Ariston ALTEAS ONE NET 30 Combi boiler's flow rate is 12 L/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. Homes with higher than average demand for hot water, and particularly those in low mains pressure areas, may find that a combi boiler is not the right answer for them.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead to better serve you and your family.


How large is the Ariston ALTEAS ONE NET 30?

The Ariston ALTEAS ONE NET 30 is TBC mm high by TBC mm wide by TBC mm deep.

Is the Ariston ALTEAS ONE NET 30 condensing or non-condensing?

We recommend that you choose a condensing boiler wherever possible like the Ariston ALTEAS ONE NET 30 - try to go for the latest model, if possible, to take advantage of improving technology.

Condensing boilers capture and recycle the warmth still present in the water vapour condensation and in flue exhaust emissions created by burning gas to make them more efficient and economical to run.

You will save money on your gas bills too, plus condensing boilers are friendlier to the environment.

Is the Ariston ALTEAS ONE NET 30 combi boiler rated as environmentally friendly?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

Central heating accounts for 14% of greenhouse gas emissions in the UK. In larger British cities, gas boilers emit dangerous levels of nitrogen dioxide into the atmosphere.

Would choosing a Ariston ALTEAS ONE NET 30 combi help in the fight against climate change? What do the performance statistics suggest?

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

The Ariston ALTEAS ONE NET 30 was awarded an efficiency rating of 94% with a SEDBUK band rating of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP), the aim of which was to ensure that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

The legislation aims to conserve energy at all life cycle stages from initial production to actual use by the customer, through to the point of disposal.

The Ariston ALTEAS ONE NET 30 has been given an ERP rating of "A" for heat and "A" for water.

How many years' warranty does the Ariston ALTEAS ONE NET 30 combi come with?

A parts and labour warranty of 12 years is included with the Ariston Ariston ALTEAS ONE NET 30 boiler.
