Grant VortexBlue 26kW Combi Oil boiler frequently asked questions

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

The Grant VortexBlue 26kW is an option you may wish to consider if you’re looking for a combi boiler for your house or flat.

In older British homes, traditional boilers required you to find room for one or more storage tanks. One tank would keep hot water warm and the other stored cold water for later heating. Manufacturers introduced combi boilers to the UK in the 1970s so that homeowners could get the warmth and hot water they needed without having to sacrifice too much valuable space – remember that residential property in this country is among the smallest in the Western world.

Combi boilers deliver hot water to your radiators and taps using water they draw directly from the mains supply. As mains water travels through a combi boiler, the technology within it heats the cold water instantly and on demand. The hot water is then distributed throughout your house.

Combi boilers have one drawback, however: they can only heat a certain amount of water within a given time. For example, if someone uses the shower and another person uses the hot water tap at the same time, water pressure drops because water reaches each point differently.

Should I install a Grant VortexBlue 26kW combi boiler in my house or apartment?

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 - the "output".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

The output of the Grant VortexBlue 26kW combi is 26 kW kilowatts, so which types of property would this be appropriate for?

An experienced PlumbProud boiler engineer would likely recommend this Grant VortexBlue 26kW Combi boiler as suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

When choosing a combi boiler like the Grant VortexBlue 26kW, 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 Grant VortexBlue 26kW Combi boiler's flow rate is 17 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.


What size is the Grant VortexBlue 26kW boiler?

The dimensions of the Grant VortexBlue 26kW are 945 mm tall, 658 mm wide, and 966 mm deep.

External, floor-standing combi boilers like the Grant VortexBlue 26kW are protected from the elements and from rusting and water ingress thanks to their solid weatherproof housings.

This type of boiler is easier for your heating engineer to access should it develop an issue or need servicing. And as it's installed outdoors, you will save valuable space in your home.

External oil boilers also have a reduced risk of indoor carbon monoxide leakage that is associated with their indoor counterparts. They also limit the potential for damage to your home or the unpleasant and difficult-to-shift odours from leaking oil.

Is the Grant VortexBlue 26kW condensing or non-condensing?

The Grant VortexBlue 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.

Does the Grant VortexBlue 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.

In Britain's bigger cities, gas boilers, in particular, are responsible for dangerous levels of nitrogen dioxide emissions. Overall, 14% of all of the UK’s greenhouse gas production comes from heating our homes.

Will you be helping the environment if you decide to install a Grant VortexBlue 26kW combi in your home? Let’s look at the figures.

All boilers manufactured and installed in the UK are required by law to have an energy efficiency rating of at least 92%, equivalent to a good “A” rating on the SEDBUK scale. Before this, the minimum was 88% (ratings of 88% and 89% are equivalent to a high “B” SEDBUK rating and anything 90% or higher is an "A" rating).

A boiler's energy efficiency rating is designed to let you know how much energy is used and wasted during normal functioning.

The Grant VortexBlue 26kW was given an efficiency rating of 91.7% and a band rating of "A".

The Energy Related Products Directive (ERP) was introduced in 2015 and it applies to all products that consume energy throughout their lifetime, including during the manufacturing process and at the point of final disposal.

The purpose of the ERP is to ensure that companies create products that are kinder to the environment by reducing both the energy they use and the harmful emissions they produce.

The Grant VortexBlue 26kW has an ERP rating of "A" for heat and "A" for hot water production.

If the Grant VortexBlue 26kW breaks down, will I be covered by the warranty?

The Grant VortexBlue 26kW boiler has a warranty covering parts and labour costs for up to 2 years after installation.

Grant VortexBlue 26kW Combi Oil boiler frequently asked questions

Which category of boiler does the Grant VortexBlue 26kW fit into?

Grant’s VortexBlue 26kW is one you might consider if you’re looking for a combi boiler for your house or flat.

Combination or combi boilers are highly efficient and save a lot of space in your home. Combi boilers heat water directly from the mains when you turn on a tap and, as a result, you don’t need a hot water storage cylinder or a cold water tank in the roof space.

These boilers are, therefore, suitable for smaller homes and especially those without a loft. They are also cost-effective as the water is heated instantly and distributed on demand rather than being stored. Combi boilers are the most popular type of boilers in the UK and replacing an older boiler with a new combi boiler will reduce your oil bills significantly.

However, there are downsides to this type of boiler. If you take a shower while someone else is using a tap, less water will reach each point of usage at lower rates of pressure and temperatures as combi boilers can only heat a certain volume of water at any given time.

Should I choose a Grant VortexBlue 26kW combi boiler for my house or flat?

Whether this Grant VortexBlue 26kW 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 oil bills than you need to for years to come.

The output of the Grant VortexBlue 26kW combi is 26 kW, so which types of property is this Grant VortexBlue 26kW Combi boiler appropriate for?

Most Gas Safe engineers would suggest that the most suitable type of property for installing a Grant VortexBlue 26kW combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

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 Grant VortexBlue 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. 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.


Dimensions of the Grant VortexBlue 26kW boiler

The Grant VortexBlue 26kW is 945 mm tall, 658 mm wide, and 966 mm deep in size.

External, floor-standing combi boilers like the Grant VortexBlue 26kW are protected from the elements and from rusting and water ingress thanks to their solid weatherproof housings.

This type of boiler is easier for your heating engineer to access should it develop an issue or need servicing. And as it's installed outdoors, you will save valuable space in your home.

External oil boilers also have a reduced risk of indoor carbon monoxide leakage that is associated with their indoor counterparts. They also limit the potential for damage to your home or the unpleasant and difficult-to-shift odours from leaking oil.

Is the Grant VortexBlue 26kW non-condensing or condensing?

We recommend the Grant VortexBlue 26kW as it is a modern condensing oil boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more oil.

Condensing boilers significantly reduce your quarterly oil costs and they're better for the environment.

How does the Grant VortexBlue 26kW combi rate environmentally?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

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 choosing a Grant VortexBlue 26kW combi help the environment? Let’s see what the performance figures suggest.

All boilers manufactured in the UK from April 2018 must operate at a minimum level of energy efficiency of 92% ("A" rating on the SEDBUK scale). Before that, the minimum was 88% - boilers scoring 88/89% were given a SEDBUK "B" rating and 90% or above an "A" rating.

The energy efficiency score of a boiler indicates how much energy it uses and how much goes to waste when in use.

After its assessment, the Grant VortexBlue 26kW was given an efficiency rating of 91.7% and 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 Grant VortexBlue 26kW is "A" for heat and "A" for water.

Is there a warranty on the Grant VortexBlue 26kW combi boiler if it breaks down?

A parts and labour warranty of 2 years is included with the Grant Grant VortexBlue 26kW boiler.
