Vaillant ecoTEC Pro 28 Combi Gas boiler frequently asked questions

Vaillant EcoTEC Pro 28 - a regular boiler, combi boiler 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.

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 Vaillant EcoTEC Pro 28 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".

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 Vaillant EcoTEC Pro 28 combi boiler has an output of 27.2 kW, so which types of property would it be most appropriate for?

Most Gas Safe engineers would suggest that the Vaillant EcoTEC Pro 28 combi boiler would be a suitable choice for installation in larger properties including detached homes with 15 or more radiators and two or more bathrooms.

The Vaillant EcoTEC Pro 28 is a combi boiler, which that means that you need to take the flow rate (measured in litres per minute) into account as well as the output rate. This Vaillant ecoTEC Pro 28 Combi boiler's flow rate is 11 L/m.

Combis draw water from the mains, instantly heating and distributing it where it's needed - taps, radiators, bathrooms, and so on.

However, this means that the flow rate of a boiler may effectively be capped by the flow rate of the mains water supply. For example, if your mains pressure is 12l/m, that is the maximum flow rate that your boiler can achieve even if you choose a boiler with a flow rate of 18l/m.

In addition, if your home has more than one bathroom, a high number of radiators, and more than one member of your household wants to use hot water at the same time regularly, the flow rate of both the boiler and the mains water pressure may not be high enough.

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 measurements of the Vaillant EcoTEC Pro 28 are 720 mm by 440 mm by 338 mm.

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

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Vaillant EcoTEC Pro 28.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

Is the combi Vaillant EcoTEC Pro 28 boiler energy efficient?

As more of us become concerned by the effects of climate change, the damage we do to the environment by heating our homes has emerged as an important issue for many homeowners.

In the UK, central heating is responsible for 14% of greenhouse gas production. Domestic gas boilers emit large quantities of nitrogen dioxide in British cities.

Would the environmental impact of installing a Vaillant EcoTEC Pro 28 combi in your home be positive? Let's look at the numbers.

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Vaillant EcoTEC Pro 28 was awarded an efficiency rating of "94%", equivalent to a "A" rating on the SEDBUK system.

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.

Is there a warranty on the Vaillant EcoTEC Pro 28 combi boiler if it breaks down?

A parts and labour warranty of 2 years is included with the Vaillant Vaillant EcoTEC Pro 28 boiler.

Vaillant ecoTEC Pro 28 Combi Gas boiler frequently asked questions

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

If you are searching for a combi boiler for your house or flat, the Vaillant EcoTEC Pro 28 is certainly one to consider.

The UK has some of the smallest homes in the Western world, which is partly why combi boilers were introduced in the 1970s. Traditional boilers require one or more large storage tanks which they use to either heat water and keep it warm or store water intended for heating later. These tanks took up a lot of space in people's homes.

Combi boilers save space because they don't require these tanks to operate. Instead, combis draw water direct from your mains supply then instantly heat and distribute it on demand.

The biggest disadvantage in using combi boilers is that they have a maximum capacity volume for heating water. While this may not be an issue in a small household, it could be for a larger household where there is higher demand for hot water. When more than one person is using the water, it is distributed between the two points, reducing the pressure and temperature at each point.

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

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

A PlumbProud heating engineer would recommend that this Vaillant ecoTEC Pro 28 Combi boiler be installed in larger properties including detached homes with 15 or more radiators and two or more bathrooms.

The Vaillant EcoTEC Pro 28 is a combi boiler, which that means that you need to take the flow rate (measured in litres per minute) into account as well as the output rate. This Vaillant ecoTEC Pro 28 Combi boiler's flow rate is 11 L/m.

Combis draw water from the mains, instantly heating and distributing it where it's needed - taps, radiators, bathrooms, and so on.

However, this means that the flow rate of a boiler may effectively be capped by the flow rate of the mains water supply. For example, if your mains pressure is 12l/m, that is the maximum flow rate that your boiler can achieve even if you choose a boiler with a flow rate of 18l/m.

In addition, if your home has more than one bathroom, a high number of radiators, and more than one member of your household wants to use hot water at the same time regularly, the flow rate of both the boiler and the mains water pressure may not be high enough.

Vaillant EcoTEC Pro 28 size

The Vaillant EcoTEC Pro 28 stands at 720 mm tall, 440 mm wide and 338 mm deep.

Is this Vaillant boiler non-condensing or condensing?

Condensing gas boilers like the Vaillant EcoTEC Pro 28 are more energy-efficient and choosing one for your home will cut the amount you pay every year for your gas.

They do this by capturing the heat in water vapour condensation and in exhaust gases which would normally be expelled via the flue. They then recycle that heat, returning it to the system to, among other tasks, reheat colder water that is returning to your boiler from your radiators.

How energy efficient is the Vaillant EcoTEC Pro 28 combi boiler?

How we heat our homes and the damage this does to the environment has become a pressing concern for many homeowners worried about the effects and impact of climate change.

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.

If you decide to install a Vaillant EcoTEC Pro 28 combi in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are graded "B" and 90% and above is graded "A").

The Vaillant EcoTEC Pro 28 was awarded an efficiency rating of 94% with a SEDBUK band rating 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 Vaillant EcoTEC Pro 28 has a rating of "A" for heat and "A" for water.

Will I be covered if the Vaillant EcoTEC Pro 28 combi breaks down?

Parts and labour charges incurred during a repair on the Vaillant Vaillant EcoTEC Pro 28 boiler are covered by a 2 year warranty.
