Ariston ALTEAS ONE NET 35 Combi Gas boiler frequently asked questions

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

You might want to consider the Ariston ALTEAS ONE NET 35 for your house or flat if you are looking for a combi boiler.

Combi boilers are excellent for providing hot water and heat for your radiators just when you need it. When you have a combi boiler installed in your home, you just turn on the tap and the hot water for your bath, shower, washing dishes and other activities is there when you need it. It also provides the heat you need to keep your radiators warm.

A combi boiler heats the cold water passing through it, which it draws from the mains. This newly heated water can then be distributed to whichever hot tap or radiator needs it.

In the past, boilers needed at least one storage tank to hold water that was either already heated or would be heated later. Sometimes, you'd have to wait for hot water because there was none left. In addition, storage tanks took up a lot of space and most UK homes are pretty small.

The main disadvantage to combi boilers is that they can only heat a certain amount of water at any one time, meaning the pressure, volume and temperature of water will decrease if more than one tap is on at the same time or if both the shower and washing machine are on together.

Is a Ariston ALTEAS ONE NET 35 combi boiler appropriate for 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".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Ariston ALTEAS ONE NET 35 combi boiler is 31 kW kilowatts. Which types of property would this be appropriate for?

A PlumbProud heating engineer would likely recommend that this Ariston ALTEAS ONE NET 35 Combi boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

Please remember to consider "flow rates" as well when choosing your new boiler. All combi boilers including the Ariston ALTEAS ONE NET 35 draw water from the mains.

Each combi boiler has its own flow rate (measured in litres per minute) - this tells you how much water it can heat and distribute to your home’s taps and radiators straight from the mains. This Ariston ALTEAS ONE NET 35 Combi boiler's flow rate is 14 L/m.

There is no benefit to you in choosing a combi with a high flow rate if your mains pressure is low - save money by buying a boiler whose flow rate is equal to or slightly more than the pressure in your water pipes.

In addition, if you have a lot of radiators and bathrooms in your home or you have a large household that often uses lots of hot water at the same time, like for regular morning and evening showers, 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 ALTEAS ONE NET 35 boiler?

The Ariston ALTEAS ONE NET 35 is TBC mm tall, TBC mm wide, and TBC mm deep in size.

Is this Ariston boiler condensing or non-condensing?

The Ariston ALTEAS ONE NET 35 is a condensing gas boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of gas to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower gas bills) and are better for the environment.

Is the combi Ariston ALTEAS ONE NET 35 boiler energy efficient?

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

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Would choosing a Ariston ALTEAS ONE NET 35 combi help in the fight against climate change? What do the performance statistics suggest?

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Ariston ALTEAS ONE NET 35 was awarded an efficiency rating of 94% with a SEDBUK grading of "A".

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use, right through to final disposal.

The Ariston ALTEAS ONE NET 35 has a rating of "A" for heat and "A" for water.

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

The parts and labour warranty offered with this Ariston ALTEAS ONE NET 35 Combi boiler covers you for 12 years.

Ariston ALTEAS ONE NET 35 Combi Gas boiler frequently asked questions

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

You may wish to consider installing the Ariston ALTEAS ONE NET 35 if you are looking for a combi boiler for your house or flat.

Traditionally, most boilers required you to find space in your property for one or more large storage tanks. These tanks would either keep water warm or hold it in reserve for later heating. Manufacturers originally introduced combi boilers to offer homeowners the same level of warmth and hot water without taking up as much space – remember that the UK has some of the smallest homes in the Western world.

With a combi boiler, the hot water needed for your radiators and taps is provided on demand. Water from the mains passes through your combi boiler and the technology within it instantly heats the cold water. It then distributes that hot water around your home.

The biggest drawback for combi boilers is that they have a maximum capacity in volume for heating water. This means that if someone wants to use the shower while another person wants to use a hot water tap, the amount of water reaching each point falls, resulting in a drop in water pressure.

Should I install a Ariston ALTEAS ONE NET 35 combi boiler in my home?

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 - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for gas than is necessary.

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

A PlumbProud boiler engineer would almost certainly recommend that this Ariston ALTEAS ONE NET 35 Combi boiler is most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

Please remember too that all combi boilers draw water from the mains - they have no storage tanks. Combis heat the water from the mains on demand and then send it to wherever it's needed in the house, like a radiator, a bathroom or a kitchen.

The speed at which it can do this is called the "flow rate", which is measured in litres per minute. If you have a lot of radiators and bathrooms in your home and multiple people are regularly trying to use the hot water at one time, such as in the morning or evening, you'll need a combi with a high flow rate. This Ariston ALTEAS ONE NET 35 Combi boiler's flow rate is 14 L/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. If the flow rate of the local water supply is 11l/m, you shouldn't purchase a boiler with a flow rate of 17l/m because it will never be able to use that extra capacity.

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 proportions of a Ariston ALTEAS ONE NET 35 boiler?

The Ariston ALTEAS ONE NET 35 is TBC mm [H] by TBC mm [W] by TBC mm [D] in size.

Is the Ariston ALTEAS ONE NET 35 a non-condensing or condensing boiler?

Condensing boilers convert the warmth present in flue exhaust gases and water vapour condensation into heat which they then recycle to increase the temperature of the colder water returning to your system.

We recommend that homeowners choose a condensing boiler like the Ariston ALTEAS ONE NET 35 for this reason - the more recent your model the better because the technology improves every year.

You'll benefit from lower quarterly gas bills and condensing boilers are also much more environmentally friendly.

Is the combi Ariston ALTEAS ONE NET 35 boiler energy efficient?

With growing concern among the public about accelerating climate change, how we heat our homes and the impact this has on the environment has become a major topic of concern for many homeowners.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

Would installing a Ariston ALTEAS ONE NET 35 combi boiler in your home be a green choice? Let's look at the numbers.

The energy efficiency rating of the Ariston ALTEAS ONE NET 35 is 94% with a SEDBUK band rating of "A".

Energy efficiency tests record how much energy is wasted on non-core functions during an operation.

By law, all boilers manufactured and supplied in the UK must have a minimum energy efficiency performance level of 92% (equivalent to a SEDBUK "A" grade). Up to April 2018, the minimum performance level was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90%+ an "A" grade).

The ERP (or Energy Related Products Directive) is European legislation which applies to all products that consume energy throughout their lifetime.

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

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

How many years' warranty does the Ariston ALTEAS ONE NET 35 combi come with?

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