Vaillant ecoTEC Pro 28 Combi Gas boiler frequently asked questions

What kind of boiler is the Vaillant EcoTEC Pro 28 - standard, combi or system?

The Vaillant EcoTEC Pro 28 is worthy of consideration if you're looking for a combi boiler for your flat or house.

Combi boilers have much to recommend them - not least the fact that they save a lot of space. Combination (or combi) boilers were introduced by manufacturers in the 1970s to provide practical central heating and hot water distribution to smaller properties - remember that UK houses and flats tend to be among the smallest in the developed world.

Traditional boilers require one or more storage tanks to keep hot water warm and to store water for heating later. In contrast, combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a storage tank. The heated water is then distributed to your taps and radiators on demand.

While combi boilers are suitable choices for many properties, especially those without a loft, there is also a disadvantage in using them. Water is heated instantly and the volume of water that can be heated at any one time is limited. This can result in less water being sent to taps and showers if more than one is being used simultaneously. In these instances, the water pressure to both points will drop.

Is the Vaillant EcoTEC Pro 28 combi suitable for my house or flat?

To determine that, we need to consider the size of the boiler. However, size doesn't refer to how big a boiler is - it means the size of its "output".

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

The output of the Vaillant EcoTEC Pro 28 combi is 27.2 kW, so which types of property would this Vaillant ecoTEC Pro 28 Combi boiler be appropriate for?

Most Gas Safe boiler installers would recommend that a boiler with this output level would be most suitable for larger properties including detached homes with 15 or more radiators and two or more 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 Vaillant ecoTEC Pro 28 Combi boiler's flow rate is 11 L/m.

Like all combi boilers, the Vaillant EcoTEC Pro 28 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.


How big is the Vaillant EcoTEC Pro 28?

The Vaillant EcoTEC Pro 28 is 720 mm [H] by 440 mm [W] by 338 mm [D] in size.

Vaillant EcoTEC Pro 28 – condensing or non-condensing?

We recommend that you choose a condensing boiler wherever possible like the Vaillant EcoTEC Pro 28 - 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 Vaillant EcoTEC Pro 28 combi an environmentally friendly boiler?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Let's take a closer look at whether installing a Vaillant EcoTEC Pro 28 combi would be a good choice for the environment.

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 Vaillant EcoTEC Pro 28 was awarded an efficiency rating of 94% with a SEDBUK grading of "A".

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 Vaillant EcoTEC Pro 28 is "A" for heat and "A" for water.

What length of warranty does the Vaillant EcoTEC Pro 28 come with?

A parts and labour warranty of 2 years is included when you purchase the Vaillant EcoTEC Pro 28 boiler through PlumbProud.

Vaillant ecoTEC Pro 28 Combi Gas boiler frequently asked questions

Is the Vaillant EcoTEC Pro 28 a standard, combi or system boiler?

The Vaillant EcoTEC Pro 28 boiler could be suitable for your house or flat if you are looking for a new combi boiler.

One of the reasons the combi boiler was introduced to Britain in the 1970s was because residential properties are among the smallest in the world. More traditional boilers require one or more large tanks to be stored around the home to function.

A combi boiler is a self-contained unit that draws water from the mains then heats and distributes it instantly and on demand - no tanks are needed.

They are the most popular type of boilers in the UK and offer only one major disadvantage - there is a maximum volume of water that can be heated at any one time. If that limit is exceeded by, for example, two people using a hot water tap at the same time, there will be a drop in water pressure, temperature and volume to both taps.

Is a Vaillant EcoTEC Pro 28 combi boiler suitable for my apartment or house?

Whether this Vaillant ecoTEC Pro 28 Combi boiler is right for where you live depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.

A boiler whose output is too high will give you hot water and warm radiators but also higher gas bills, whereas a boiler whose output is too low will result in cheaper gas bills but the water might not always be as hot as you want it to be.

The output of the Vaillant EcoTEC Pro 28 combi is 27.2 kW, so which types of property would this model be appropriate for?

A heating engineer would recommend that this Vaillant ecoTEC Pro 28 Combi boiler would provide adequate heating and hot water for larger properties including detached homes with up to 15 or more radiators and two or more 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 Vaillant ecoTEC Pro 28 Combi boiler's flow rate is 11 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 dimensions does a Vaillant EcoTEC Pro 28 have?

The Vaillant EcoTEC Pro 28 has the following dimensions - 720 mm high, 440 mm wide, and 338 mm deep.

Is the Vaillant EcoTEC Pro 28 condensing or non-condensing?

We strongly recommend that you choose a condensing boiler like the Vaillant EcoTEC Pro 28 - 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 Vaillant EcoTEC Pro 28 combi an environmentally friendly boiler?

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

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 installing a Vaillant EcoTEC Pro 28 combi boiler in your home be a green choice? Let's look at the numbers.

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 Vaillant EcoTEC Pro 28 is rated as 94% energy efficient, equivalent to a "A" SEDBUK rating.

The Energy Related Products Directive intends to encourage all manufacturers to reduce the harmful gas emissions associated with the products they make, from the manufacturing stage to final disposal, including when they are in active use.

The Vaillant EcoTEC Pro 28 has an ERP rating of "A" for heat and "A" for hot water.

Am I covered if my Vaillant EcoTEC Pro 28 combi boiler breaks down?

Vaillant offers a parts and labour warranty of 2 years on the Vaillant EcoTEC Pro 28.
