Grant Vortex Pro 26 Combi Oil boiler frequently asked questions

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

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.

In the past, most boilers needed one or more storage tanks to operate - one to store warm water and the other for storing water to be heated later. But storage tanks are problematic in properties where space is at a premium and particularly where there is no loft. Many properties in the UK are small and so manufacturers introduced combi boilers in the 1970s to eliminate the need for tanks.

With a combi boiler, the hot water for your radiators and taps is delivered on demand. The boiler instantly heats water it draws directly from the mains internally. It then distributes the heated water around your home at mains pressure as you need it.

It is important to bear in mind that, while combi boilers have many benefits, they can only heat a certain volume of water at any given time. This means that, if you run a shower at the same time as someone else is doing the washing up in the kitchen, the volume of water passing to each point will drop, causing a fall in pressure.

Is a Grant Vortex Pro 26 combi boiler appropriate for my house or apartment?

You should make sure that the boiler you install in your property is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your oil bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Grant Vortex Pro 26 combi's output at 26 kW, which types of property would this Grant Vortex Pro 26 Combi boiler be most appropriate for?

Most heating engineers would suggest that the Grant Vortex Pro 26 combi boiler would be a suitable choice for installation in smaller homes and apartments with up to 10 radiators and 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.


Making space for the Grant Vortex Pro 26

The Grant Vortex Pro 26 is 860 mm [H] by 614 mm [W] by 606 mm [D] in size.

Wall-hung boilers have been the most popular installation choice over the last 20 years because they're compact, discreet, and don’t take up much space. Yet there are still hundreds of thousands of UK homeowners whose central heating is provided by floor-standing boilers like the Grant Vortex Pro 26, which they're looking to replace to free up more living space. This is possible, however please be aware that there may be an additional cost if we need to replace your existing pipework.

That said, you should be able to fully recoup your investment within a few years thanks to the quarterly savings you'll make on your oil bills.

It's important to note that if you are thinking about replacing your current heat only or system boiler with the Grant Vortex Pro 26, your hot water cylinder and/or cold water tank will also have to be removed.

If you require further help in making the right choice, please contact PlumbProud and our team will advise you on the best course of action for you.

Vortex Pro 26 – condensing or non-condensing?

The Grant Vortex Pro 26 is a condensing oil boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

How does the Grant Vortex Pro 26 combi boiler rate environmentally?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

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.

Will you be helping the environment if you decide to install a Grant Vortex Pro 26 combi in your home? Let’s look at 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 Vortex Pro 26 has an efficiency rating of 89.5% with a SEDBUK grade of "A".

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.

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

Grant’s Vortex Pro 26 boiler includes a parts and labour warranty of 2 years.

Grant Vortex Pro 26 Combi Oil boiler frequently asked questions

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

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

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 a Grant Vortex Pro 26 combi boiler right for my house or apartment?

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

This Grant Vortex Pro 26 Combi boiler gets its power from oil and the power it's capable of producing is measured in kilowatts - the output rate is actually a kilowatt rate. The higher the output rate, the more kilowatts a boiler can use when heating water.

If you choose a boiler whose output rate is too low, it may not have enough power to make your water as hot as you would like. If you choose a boiler whose output rate is too high, you won't have to put up with lukewarm water but you will face higher oil bills.

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

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

You'll also need to be sure to choose a combi boiler with the right flow rate for your home.

The flow rate indicates the maximum volume of hot water (measured in litres per minute) that your boiler can distribute at any given time. This means that if you and your family are likely to be using several taps and showers simultaneously or you have a lot of radiators, you need a boiler with a high flow rate. This Grant Vortex Pro 26 Combi boiler's flow rate is 17 L/m.

As with all combi boilers, the Grant Vortex Pro 26 is only able to heat and distribute water at the rate at which it actually enters your property.

For this reason, you shouldn't purchase a boiler with a very high flow rate if the flow rate in your mains pipes is lower because the extra capacity doesn't mean it can draw more water from the mains pipes.

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 are the dimensions of the Grant Vortex Pro 26 boiler?

The Grant Vortex Pro 26 boiler measures 860 mm [H] x 614 mm [W] x 606 mm [D] in size.

Despite the increase in demand for compact, wall-mounted boilers over the last 20 years, hundreds of thousands of homes still have large floor-standing boilers like the Grant Vortex Pro 26. If you would like a wall-mounted boiler to replace your existing floor-standing unit to free up space, we can carry out this installation for you but please bear in mind that we may also need to replace your existing pipework, which will add extra costs to the work.

You should however be able to repay your investment in full within a few years with the savings you make on your oil bills.

Please note that you'll need to remove your hot water cylinder and/or expansion tank if you intend to replace your current heat only boiler or system boiler with the Grant Vortex Pro 26.

Contact PlumbProud, and we'll share our experience and assistance for the best course of action.

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 an environmentally friendly boiler?

As more of us become concerned by the effects of climate change, the damage we do to the environment by heating our homes has emerged as 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.

Do the figures suggest that installing the Grant Vortex Pro 26 combi at your property would help in the fight against climate change?

By law, the minimum level of energy efficiency for boilers manufactured in the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the Grant Vortex Pro 26 was given a 89.5% energy efficiency rating and a SEDBUK grading of "A".

The Energy Related Products Directive (ERP) is European legislation that applies to all products which use or consume energy during their lifespan, including during the manufacturing process and when they're in actual use, right through to the point of final disposal.

The aim is to encourage manufacturers to create new products that are kinder to the environment and create fewer harmful gas emissions.

The Grant Vortex Pro 26 has an ERP Heat rating of "A" and an ERP Water rating of "A".

What length of warranty does the Grant Vortex Pro 26 come with?

Parts and labour charges incurred during a repair on the Grant Grant Vortex Pro 26 boiler are covered by a 2 year warranty.
