Grant Vortex Pro 26kW Combi Oil boiler frequently asked questions

Is the Grant Vortex Pro 26kW a system, regular or combi boiler?

When looking for a combi boiler for your house or flat, the Grant Vortex Pro 26kW might be a suitable option for you.

In many properties, combi boilers are more suitable than traditional types of boiler. Combi boilers heat water instantly on demand, which they draw directly from the mains supply, removing the need for storage tanks that can take up valuable space in your home.

A combi boiler is often the right choice for a smaller property, particularly if your home doesn't have a useable loft. As water is heated and delivered immediately rather than being kept warm for hours in an immersion tank, combi boilers reduce oil usage, thereby minimising your heating costs.

The main disadvantage of combi boilers is that they can only heat a certain amount of water at any one time. This means that, if two people are using different taps or showers within your home at the same time, the flow of heated water to each will be reduced, as will the water pressure and temperature.

Should I install a Grant Vortex Pro 26kW combi boiler in my house or flat?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Grant Vortex Pro 26kW combi's output level is 26 kW, so which types of property would this Grant Vortex Pro 26kW Combi boiler be an appropriate choice for?

A PlumbProud boiler engineer would recommend that this Grant Vortex Pro 26kW Combi boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

With all combi boilers, you need to consider the "flow rate" as well as the output rate when making your decision.

Like all combi boilers, the Grant Vortex Pro 26kW 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. This Grant Vortex Pro 26kW Combi boiler's flow rate is 17 L/m.

There is no benefit to purchasing a boiler with a high flow rate if the local water pressure is not that good - a high flow rate doesn't mean that your combi can draw more water from the mains.

In addition, if you live in a home with a large number of radiators and more than one bathroom and if more than one person regularly wants to use hot water at a time, a combi boiler may struggle to provide enough water at a hot enough temperature.

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.


Grant Vortex Pro 26kW - size in millimetres

The Grant Vortex Pro 26kW measures 857 mm in height by 515 mm in width by 606 mm in depth.

Many homeowners dislike the floor-standing boilers (like the Grant Vortex Pro 26kW) they have in their properties because they feel that they are bulky and take up too much room. If this is you and you want to replace what you have now with a compact, wall-mounted boiler, we can do this for you, although please note that you may need to pay for new piping.

The oil bill savings offered by modern boilers are significant, however, and you should be able to recoup your investment in a few years.

You will also need to remove your hot water cylinder and/or expansion tank if you replace your current heat only or system boiler with the Grant Vortex Pro 26kW.

Please get in touch with PlumbProud for information and advice on how to proceed and we'll provide you with our recommendations.

Vortex Pro 26kW – condensing or non-condensing?

The Grant Vortex Pro 26kW is a condensing oil boiler - we strongly recommend that you choose one of the latest condensing models if possible.

With a condensing boiler, you save money on your oil bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

Is the Grant Vortex Pro 26kW combi considered environmentally friendly?

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

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Would choosing a Grant Vortex Pro 26kW combi help in the fight against climate change? What do the performance statistics suggest?

The Grant Vortex Pro 26kW has been awarded an efficiency rating of 90% 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.

The aim of the Energy Related Products (ERP) Directive is to reduce the harmful gas emissions created during a product’s manufacture and active end use right through to its disposal.

The ERP rating for the Grant Vortex Pro 26kW is "A" for heat and "A" for water.

What warranty does the Grant Vortex Pro 26kW combi boiler come with?

The Grant Vortex Pro 26kW boiler comes with a parts and labour warranty of 2 years.

Grant Vortex Pro 26kW Combi Oil boiler frequently asked questions

Grant Vortex Pro 26kW - combi, system or regular boiler?

The Grant Vortex Pro 26kW is a combi boiler you may wish to consider if you want this type of boiler for your house or flat.

Traditionally, boilers needed one or more large tanks installed in your property to store their heated water or water that was to be heated later. These tanks were often too large to be practical for most homes so the combi boiler was introduced to Britain in the 1970s by manufacturers to help homeowners overcome this issue.

Instead of using tanks as storage, a combi boiler heats water on demand. It draws water from the mains and heats it instantly on demand before distributing it to wherever it is needed in a property, be it your taps or radiators.

Unfortunately, combi boilers have one main disadvantage for larger properties or larger households. Because they have a maximum volume of water that can be heated on demand at any given time, water pressure, volume and temperature will drop if, for example, someone is taking a shower and another person in your home wants to use a hot water tap at the same time.

Is a Grant Vortex Pro 26kW combi the right boiler 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 - 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 oil than is necessary.

The Grant Vortex Pro 26kW combi boiler has an output level of 26 kW, so which types of property would it be appropriate for?

An experienced Gas Safe engineer would be likely to recommend that this Grant Vortex Pro 26kW Combi boiler is capable of providing heating and hot water to up to 10 radiators and one bathroom and would therefore be most suitable for smaller homes and apartments.

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 Grant Vortex Pro 26kW Combi boiler's flow rate is 17 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.


What are the proportions of a Grant Vortex Pro 26kW boiler?

The Grant Vortex Pro 26kW is 857 mm high by 515 mm wide by 606 mm deep.

Hundreds of thousands of properties still have floor-standing boilers like the Grant Vortex Pro 26kW in the UK, although wall-hung boilers are now the obvious choice for most homeowners wanting more living space. It is possible to replace your existing floor-standing boiler with one that is compact if you'd like to but you should consider that much of the pipework will need to be replaced in addition to the cost of the boiler and its installation.

Eventually, your savings on oil bills will pay for the one-time investment but it will take a few years.

Please bear in mind that replacing your existing system or heat only boiler with the Grant Vortex Pro 26kW will also involve the removal of your hot water cylinder and/or cold water tank.

If you would like further guidance, please contact PlumbProud for free support.

Is the Grant Vortex Pro 26kW a non-condensing or condensing boiler?

We recommend that you select a condensing boiler like the Grant Vortex Pro oil Grant Vortex Pro 26kW for your home if possible because of the environmental benefits and the money you'll save on your oil bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning oil for reuse.

Does the Grant Vortex Pro 26kW combi protect the environment?

As more of us are increasingly concerned about climate change, how we heat our homes and its impact on the environment has become an issue of importance to homeowners.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Would choosing a Grant Vortex Pro 26kW combi help in the fight against climate change? What do the performance statistics suggest?

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 Grant Vortex Pro 26kW is rated as 90% energy efficient, equivalent to a "A" SEDBUK rating.

The ERP (Energy Related Products Directive) is European legislation that aims to reduce the use of energy at all points during a product's life, from the point of manufacture to when it's in active use right through to final disposal.

The regulation aims is to encourage manufacturers to create products that are more environmentally friendly and which reduce the harmful gas emissions associated with those products.

The ERP gradings for the Grant Vortex Pro 26kW are "A" for heat and "A" for hot water.

Will I be covered if the Grant Vortex Pro 26kW combi breaks down?

The parts and labour warranty on the Grant Vortex Pro 26kW lasts for 2 years.
