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?

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

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.

Would the Ariston ALTEAS ONE NET 35 combi be a suitable boiler for my house or flat?

Whether this Ariston ALTEAS ONE NET 35 Combi boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions, however - it means how powerful it is.

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher gas bills than you need to for years to come.

The output of the Ariston ALTEAS ONE NET 35 combi is 31 kW, so which types of property is this Ariston ALTEAS ONE NET 35 Combi boiler appropriate for?

An experienced Gas Safe boiler installer would recommend that, at this level of output, the most suitable type of property for this Ariston ALTEAS ONE NET 35 Combi boiler would be medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

When choosing a combi boiler like the Ariston ALTEAS ONE NET 35, you need to consider the "flow rate" as well as the output rate. Flow rates (measured in litres per minute) indicate the volume of hot water that the boiler can heat up and then distribute to your taps and radiators.

However, combi boilers draw water from the mains and this means they can only heat the amount of water that actually enters your property.

What this means is that, if your mains pressure is 12 litres per minute, that is your boiler's effective flow rate even if it has the capacity to process 18 litres per minute. This Ariston ALTEAS ONE NET 35 Combi boiler's flow rate is 14 L/m.

To give you an idea of the flow rate you might need, a power shower typically requires around 12 litres of water per minute and a basin tap requires 4-8 litres per minute.

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 Ariston ALTEAS ONE NET 35 boiler is TBC mm high, TBC mm wide, and TBC mm deep.

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

We strongly recommend that you choose a condensing boiler like the Ariston ALTEAS ONE NET 35 - the technology is improving every year so the newer the boiler, the better.

A condensing boiler captures and recycles the warmth still present in flue exhaust gases and water vapour condensation into heat, allowing it to perform more efficiently on tasks like heating the colder water returning from your radiators.

They also offer significant annual savings on household gas bills as well as being more environmentally friendly.

Is the Ariston ALTEAS ONE NET 35 combi boiler good for the environment?

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.

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.

Will you be helping the environment if you decide to install a Ariston ALTEAS ONE NET 35 combi in your home? Let’s look at the figures.

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".

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 35 is "A" for heat and "A" for hot water.

Ariston ALTEAS ONE NET 35 Combi Gas boiler frequently asked questions

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

The Ariston ALTEAS ONE NET 35 boiler could be suitable for your house or flat if you are looking for a new combi boiler.

Boilers traditionally required the installation of one or more large tanks around your property. These were filled with water that was either being heated or was to be heated later. British homes are among the smallest in the world so, to solve the space problem, manufacturers introduced combi boilers in the 1970s to offer homeowners the warmth and hot water supply they needed while taking up much less space.

A combi boiler is designed to heat both radiators and taps on demand and at the same time. Water from the mains passes through a combi boiler and the boiler's technology instantly turns it into hot water. Your boiler then distributes the hot water throughout your home.

The main disadvantage of combi boilers is that they have a maximum water volume capacity. What this means is that, if one person is using the shower while another uses a hot tap simultaneously, less water gets to each area, resulting in a fall in water pressure at both points.

Is the Ariston ALTEAS ONE NET 35 combi boiler suitable for my house or apartment?

You should make sure that the boiler you install in your property 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 has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Ariston ALTEAS ONE NET 35 combi's output at 31 kW, which types of property would this Ariston ALTEAS ONE NET 35 Combi boiler be most appropriate for?

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

With combi boilers, you need to consider the flow rate as well as the output rate. The flow rate (shown in litres per minute) measures how much water your boiler can draw from the mains which it then instantly heats and distributes to your taps and radiators.

However, a high flow rate is of little to no value if your local water pressure is low. If your local mains water pressure is 10l/m and your flow rate is 12l/m, your boiler will only be able to process 10l/m.

If you live in an area with high water pressure but your household has multiple bathrooms and/or radiators and many members of your household want to use hot water at the same time (like morning or evening baths or showers), it's unlikely that you'll be able to find a combi with a high enough flow rate.

As an indication, a power shower needs about 10 litres of water per minute, whereas the flow rate of this Ariston ALTEAS ONE NET 35 Combi boiler is 14 L/ml/m.

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.


Where will the Ariston ALTEAS ONE NET 35 fit in my house?

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

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 Ariston ALTEAS ONE NET 35 combi boiler good for the environment?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British 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.

Will installing a Ariston ALTEAS ONE NET 35 combi be a positive contribution to the environment? Let's see what the experts say.

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The Ariston ALTEAS ONE NET 35 was awarded an efficiency rating of 94% and a band rating of "A".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

All products that consume energy throughout their lifespan must comply with the Energy Related Products (ERP) Directive.

Companies are legally obliged to reduce harmful gas emissions at all stages of a product's life cycle, from initial manufacturing right through to final disposal as well as when the product is in actual use.

The Ariston ALTEAS ONE NET 35 scores "A" for heat and "A" for water.

Will I be covered if the Ariston ALTEAS ONE NET 35 combi breaks down?

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