Grant VortexBlue 26kW Combi Oil boiler frequently asked questions

What type of boiler is the Grant VortexBlue 26kW?

If you’re looking for a combi boiler for your house or flat, you may wish to the consider the Grant VortexBlue 26kW.

Traditional boilers have one or two tanks - one holds hot water to keep it warm and the other water for later heating. Because UK residential property is among some of the smallest in the world, manufacturers introduced combi boilers and the heat pumps that go in them in the 1970s to reduce the amount of space boilers needed to take up.

The hot water needed for your radiators and taps is available on demand when you have a combi boiler. Combi boilers use technology located within the boiler to heat cold water, which it draws from the mains, and to distribute hot water where it's needed around your home.

A combi boiler, however, has the disadvantage of a maximum capacity for the amount of water it can heat. The result is that if someone uses the shower while another uses a hot water tap simultaneously, the amount of water reaching each point falls, causing water pressure to drop.

Is a Grant VortexBlue 26kW combi boiler suitable for 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 VortexBlue 26kW combi's output level is 26 kW, so which types of property would this Grant VortexBlue 26kW Combi boiler be an appropriate choice for?

An experienced PlumbProud heating engineer would recommend that the level of output from this Grant VortexBlue 26kW Combi boiler would make it a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.

If you are considering installing a combi boiler in your home, you need to consider the flow rate as well as the output rate.

The flow rate is the volume of water (measured in litres per minute) that your boiler can instantly heat up and send around the home. The more demand in your home for water at the same time (for example, two people taking showers in different bathrooms), the higher the flow rate you'll need.

However, the actual flow rate your boiler can deliver is also determined by your mains water pressure. If you choose a boiler with a flow rate of 16l/m but the mains water pressure is 12l/m, your boiler will only perform to 12l/m. This Grant VortexBlue 26kW Combi boiler's flow rate is 17 L/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.


Grant VortexBlue 26kW size

The Grant VortexBlue 26kW has the following dimensions - 945 mm high, 658 mm wide, and 966 mm deep.

There are several benefits to choosing an external, floor-standing combi boiler like the Grant VortexBlue 26kW. External boilers free up space indoors and reduce internal noise pollution to almost zero. They are also easier for an engineer to access if a problem develops and an external boiler reduces the chances of carbon monoxide leaking into your property.

External boilers are fitted in weatherproof housing and are perfect for homes that require oil-fired heating because they are not connected to mains gas. Leakage is always a possibility with oil boilers but, as this Grant VortexBlue 26kW Combi boiler is fitted outside your home, there is likely to be much less damage to your property if it leaks and no odour of oil in your home.

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

We recommend that you select a condensing boiler like the Grant VortexBlue oil Grant VortexBlue 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.

Is the Grant VortexBlue 26kW combi rated as environmentally friendly?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.

Would choosing the Grant VortexBlue 26kW combi boiler be an environmentally friendly decision? Here's what the figures say.

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 Grant VortexBlue 26kW was awarded an efficiency rating of 91.7% with a SEDBUK band rating of "A".

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from the initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The Grant VortexBlue 26kW has a rating of "A" for heat and "A" for water.

Am I covered if the Grant VortexBlue 26kW combi boiler breaks down?

The Grant VortexBlue 26kW boiler comes with a parts and labour warranty lasting 2 years.

Grant VortexBlue 26kW Combi Oil boiler frequently asked questions

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

If you’re looking for a combi boiler for your house or flat, then the Grant VortexBlue 26kW is one you may wish to consider.

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 Grant VortexBlue 26kW combi boiler suitable for my apartment or house?

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?

To most experienced Gas Safe engineers, the Grant VortexBlue 26kW combi VortexBlue would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

With combi boilers like the Grant VortexBlue 26kW, you need to take the flow rate into account as well as the output rate.

Combi boilers draw water from the mains and then instantly heat that water and send it to wherever in your home it's needed. Flow rates, measured in litres per minute, are subject to the mains water pressure in your area. So, for example, if the local mains water pressure is 11 litres per minute and the flow rate of your boiler is 14 litres per minute, the boiler will not be able to process more than 11 litres per minute. The flow rate of this Grant VortexBlue 26kW Combi boiler is 17 L/m.

If you live in a home with lots of radiators or bathrooms where many people want to use hot water at the same time, a combi boiler may not be able to cope. For reference, a power shower uses about 10 litres of water per minute. If two people want showers at the same time or one person wants a shower and the other hot water from a tap in the kitchen, your boiler may not have a large enough flow rate even if the local mains water pressure is high.

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

Grant’s VortexBlue 26kW is 945 mm tall, 658 mm wide, and 966 mm deep.

The Grant VortexBlue 26kW boiler is an external, floor-standing combi boiler benefiting from sturdy weatherproof housing that provides reliable protection from the UK’s changeable weather, rusting, and water ingress.

Because they're installed outdoors, you save valuable space inside your home and you'll never hear the boiler in operation. An external boiler is also much easier for a service engineer to access if it breaks down or needs repair.

External boilers cut the risk of carbon monoxide leaking into your home and, because the oil it uses for power is stored outside, you greatly reduce the potential for indoor oil leakages which often cause severe damage as well as unpleasant odours that can be very hard to get rid of.

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

The Grant VortexBlue 26kW is a condensing oil boiler - in fact, we recommend that you select this model or one of the latest condensing boilers on the market as the technology continues to improve over time.

Condensing boilers capture the heat still present in the flue exhaust gases and water vapour condensation created when the oil is burned and they recycle this back into the heating system to warm up the cold water re-entering the boiler from your radiators.

They're much more environmentally friendly and installing one results in much lower annual oil bills.

Is the Grant VortexBlue 26kW combi boiler rated as environmentally friendly?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Will choosing a Grant VortexBlue 26kW combi boiler for your home be positive for the environment? Let's examine the figures.

All boilers manufactured after April 2018 in the UK must be rated as an “A” on the SEDBUK grading system, subject to a minimum energy efficiency rating of 92% or above. Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Grant VortexBlue 26kW has an efficiency rating of 91.7% with a SEDBUK grade 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 Grant VortexBlue 26kW has a rating of "A" for heat and "A" for water.

What is the warranty period for the Grant VortexBlue 26kW?

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