Grant Vortex Pro 26 Combi Oil boiler frequently asked questions

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

Looking for a oil combi boiler for your house or flat? If you are, the Grant Vortex Pro 26 boiler may be worth considering.

Combi boilers were introduced by manufacturers in the 1970s to offer British homeowners a way to cheaply and reliably heat their homes and have hot water without taking up too much space. Previously, most boilers had one or more storage tanks, which either heated water and kept it warm or held water to be heated later.

With combi boilers, there is no need to find space for large tanks around your home as the hot water needed for your radiators and taps is available on demand. Combi boilers do this by drawing water from your mains supply, heating it instantly whenever you need it and then distributing it to where it's needed in the home.

The major disadvantage to combi boilers is that they have a maximum capacity for heating water. In a larger household, water pressure, volume and temperature will drop if two or more people are trying to use hot water at the same time.

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

A boiler engineer would recommend that, at this level of output, the most suitable type of property for this Grant Vortex Pro 26 Combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

In addition to output rates, you need to consider a combi boiler's flow rate when making your choice.

The flow rate of your boiler dictates the maximum volume of water (measured in litres per minute) that it can heat and distribute to your taps, showers and radiators at any one time.

However, a combi boiler like the Grant Vortex Pro 26 can only heat and deliver water at the rate at which it actually enters your property. For this reason, you should also find out what the mains pressure to your house is before purchasing a boiler.

It's pointless spending more money on a boiler with a 17l/m flow rate if the local water pressure is 11l/m. To give you an indication of average water demand, a power shower typically requires 12 litres of water per minute and a basin tap 4-8 litres. This Grant Vortex Pro 26 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.


Making space for the Grant Vortex Pro 26

The Grant Vortex Pro 26 measures 945 mm in height and has a width of 658 mm and a depth of 754 mm.

External, floor-standing combi boilers like the Grant Vortex Pro 26 are installed outdoors saving you valuable space inside your home as well as protecting you from the noise made by a oil boiler during its operation.

Supplied in sturdy, weatherproof housing that protects it from rusting and water ingress, external boilers are much easier for heating engineers to gain access to in case of repair or on maintenance visits.

Because the boiler is not inside your property, carbon monoxide fumes escape into the atmosphere if there is a leak. In addition, there's little to no chance of oil getting into your home if the boiler malfunctions - oil spills inside your property can cause significant damage and leave unpleasant odours that can be very hard to shift.

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

Condensing oil boilers like the Grant Vortex Pro 26 are more energy-efficient and choosing one for your home will cut the amount you pay every year for your oil.

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.

Is the Grant Vortex Pro 26 combi boiler good for the environment?

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

Would choosing a Grant Vortex Pro 26 combi help the environment? Let’s see what the performance figures suggest.

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 Vortex Pro 26 has an efficiency rating of 91.7% with a SEDBUK grade of "A".

In 2015, the Energy Related Products Directive (ERP) came into force. The legislation applies to all products that consume energy in production, during their active life, and at the point of final disposal.

The ERP was introduced to incentivise manufacturers to create products that emitted fewer harmful gases with the larger aim of protecting the wider environment.

The Grant Vortex Pro 26 has been awarded an ERP rating of "A" for heat and "A" for water.

How long am I covered by the warranty for if the Grant Vortex Pro 26 breaks down?

The Grant Vortex Pro 26 is supplied with a parts and labour warranty of 2 years.

Grant Vortex Pro 26 Combi Oil boiler frequently asked questions

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

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

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 Grant Vortex Pro 26 combi suitable for my house or flat?

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

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

The Grant Vortex Pro 26 combi's output is 26 kW, so which types of property would this Grant Vortex Pro 26 Combi boiler be appropriate for?

A heating engineer would recommend that the Grant Vortex Pro 26 combi boiler would be a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.

Homeowners considering fitting a combi boiler to their home need to consider flow rates as well as output rates.

The flow rate is a measurement of the volume of water a combi can instantly heat and send to the taps and radiators around your home. The higher the likely demand for hot water in your home, the higher your combi's flow rate should be. This Grant Vortex Pro 26 Combi boiler's flow rate is 17 L/m.

Unlike heat only or system boilers, combi boilers don't store hot water in a tank for later use - instead, they draw it directly from the mains. This means that the volume of water your boiler can actually process is constrained by the flow rate of water in the mains pipe.

So, if you choose a combi boiler with a 15l/m flow rate but the flow rate in your mains pipe is 12l/m, the combi boiler's working flow rate is also 12l/m.

Combi boilers are also not always the correct choice for homes with multiple bathrooms, a high number of radiators, or where more than one family member will want to use hot water at the same time.

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.


The dimensions of the Grant Vortex Pro 26 are

The size of the Grant Vortex Pro 26 boiler is 945 mm high, 658 mm wide, and 754 mm deep.

External floor-standing combi boilers like the Grant Vortex Pro 26 don't take up space in the home (they're fitted outside) and it's almost impossible to hear them when in operation (unlike internal boilers). They're much easier for a service technician to access if something goes wrong and there's less chance of carbon monoxide leaking into your home.

This Grant Vortex Pro 26 Combi boiler features weatherproof housing meaning a minimal risk of rusting and water ingress. In addition, as the boiler is outside your home, there is a lower chance of oil leaking into your property, which can cause damage and difficult-to-remove odours.

Vortex Pro 26 – condensing or non-condensing?

Condensing oil boilers like the Grant Vortex Pro 26 are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less oil to run.

Is the Grant Vortex Pro 26 combi boiler good for the environment?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Would installing a Grant Vortex Pro 26 combi boiler in your home help combat climate change? What do the figures suggest?

The energy efficiency rating of the Grant Vortex Pro 26 is 91.7% with a SEDBUK band rating of "A".

Energy efficiency tests record how much energy is wasted on non-core functions during an operation.

By law, all boilers manufactured and supplied in the UK must have a minimum energy efficiency performance level of 92% (equivalent to a SEDBUK "A" grade). Up to April 2018, the minimum performance level was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90%+ an "A" grade).

The ERP (or Energy Related Products Directive) is a European regulation governing products which require energy to operate throughout their lives and encourages manufacturers to create products that are more environmentally friendly.

The legislation is designed to reduce the potential for harmful gas emissions during manufacturing and actual use right through to the point of final disposal.

For the Grant Vortex Pro 26, the ERP rating is "A" for heat and "A" for hot water production.

Is there a warranty on the Grant Vortex Pro 26 combi boiler if it breaks down?

The manufacturer offers a parts and labour warranty of 2 years on the Grant Vortex Pro 26 boiler to new customers.
