Grant Vortex Pro 26 Combi Oil boiler frequently asked questions

What type of boiler is the Grant Vortex Pro 26 - regular, system or combi?

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

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.

Should I install a Grant Vortex Pro 26 combi boiler in 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?

Most experienced boiler engineers would recommend this Grant Vortex Pro 26 Combi boiler as a suitable option for smaller homes and apartments with no more than 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 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.


What size is the Grant Vortex Pro 26 boiler?

The Grant Vortex Pro 26 boiler measures 945 mm [H] x 658 mm [W] x 754 mm [D] in size.

Floor-standing external combi boilers like the Grant Vortex Pro 26 are safer as the oil it uses for fuel is not stored inside your home meaning there is little to no chance of an internal leak occurring which can damage your home and leave oily odours that become difficult to eradicate.

External boilers free up space in your home and because they're outside, you rarely hear them working. In addition, a service engineer can quickly fix it if it has problems, and there is a lower chance of carbon monoxide entering your home.

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

We recommend that, if possible, you select one of the very latest condensing oil boilers on the market like the Grant Vortex Pro 26.

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 oil bill over 5-10 years add up to more than you pay for the boiler itself.

Is the Grant Vortex Pro 26 combi considered environmentally friendly?

Price and performance are two important issues when choosing a boiler but now, for many people in the UK, so is the environmental impact of how we heat our homes and its effect on climate change.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

Is the Grant Vortex Pro 26 combi an environmentally friendly choice for your home? Let’s have a look at the figures.

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 oil bills.

The Grant Vortex Pro 26 was awarded an efficiency rating of "91.7%", 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 Grant Vortex Pro 26 has an ERP rating of "A" for heat and "A" for hot water.

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

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

Grant Vortex Pro 26 Combi Oil boiler frequently asked questions

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

The Grant Vortex Pro 26 boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

Traditional boilers require at least one large cylindrical tank to work, normally housed in a large landing cupboard, utility room or the attic. As the UK has some of the world's smallest residential properties, manufacturers introduced the combi boiler in the 1970s to address the issue of space while meeting homeowners' need for central heating and hot water at the same time.

Combi boilers don't need external storage tanks. Instead, they draw water directly from the mains, heat it and then distribute it on demand to the areas where it is needed.

The most important disadvantage of combi boilers is that they have a maximum capacity for the amount of water they can heat up. This means that, if one person in your household is having a shower and another person turns on a hot water tap elsewhere, then the volume, pressure and temperature of the water to both points decreases.

Would the Grant Vortex Pro 26 combi be a suitable boiler 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.

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your oil bills will go up and not down.

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

A PlumbProud Gas Safe engineer would recommend that the most suitable type of property for a Grant Vortex Pro 26 combi would be smaller homes and apartments containing up to 10 radiators and providing hot water for one bathroom.

If you are thinking about installing a combi boiler like the Grant Vortex Pro 26 in your home, you should consider flow rates as well as output rates. This Grant Vortex Pro 26 Combi boiler's flow rate is 17 L/m.

The flow rate indicates the maximum volume of water (measured in litres per minute) that your boiler can heat up and send to your radiators, taps and showers at any one time. The more taps and showers that could be in use simultaneously or the greater the number of radiators you have, the higher the flow rate you need.

However, you should establish what the mains pressure is at your property as a combi boiler can only heat the water that comes into your home.

For example, if your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate capacity. Typically, a power shower will require 10 litres of water 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.


The size of the Grant Vortex Pro 26

The Grant Vortex Pro 26 is 945 mm [H] by 658 mm [W] by 754 mm [D] in size.

Floor-standing external combi boilers like the Grant Vortex Pro 26 operate reliably and consistently outdoors because of their solid weatherproof housing designed to protect against rusting and water ingress. And, because they're not installed inside your property, you save valuable indoor space.

Internal oil boilers can leak and, when they do, they damage your property and leave unpleasant odours which are hard to remove. An external boiler eliminates the risk of indoor oil leaks and the danger of carbon monoxide getting into your home is also greatly reduced. An external boiler is easier for your heating engineer to access when it requires servicing or repair.

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

We strongly recommend that you choose a condensing boiler like the Grant Vortex Pro 26 - the technology is improving every year so the newer the boiler, the better.

A condensing boiler captures and recycles the warmth still present in flue exhaust gases and water vapour condensation into heat, allowing it to perform more efficiently on tasks like heating the colder water returning from your radiators.

They also offer significant annual savings on household oil bills as well as being more environmentally friendly.

Is the Grant Vortex Pro 26 combi boiler environmentally friendly?

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

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

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

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 Vortex Pro 26 was given an efficiency rating of 91.7% and a SEDBUK grading 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 Vortex Pro 26 has a rating of "A" for heat and "A" for water.

What is the warranty period for the Grant Vortex Pro 26?

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