Grant Vortex Pro 26kW Combi Oil boiler frequently asked questions

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

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

Combi boilers provide hot water or heating for your home on demand. You just need to turn the tap to get hot water or switch on the radiator and you’ll feel your home warm up within minutes.

In contrast, traditional boilers required either one or two large storage tanks to work - one to heat and keep water warm and the other to hold cold water for later heating. If the immersion tank was empty, it wasn’t uncommon to wait up to an hour for enough hot water to fill a bath, for example.

Combi boilers draw cold water from the mains and then heat it instantly whenever it's needed, all from one small unit.

The one disadvantage to combi boilers is that, if more than one point is in use at any one time (for example, if someone is taking a shower and another person turns on a hot water tap elsewhere in the property), water pressure, temperature and volume drop to both points.

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

An experienced boiler engineer would recommend that this Grant Vortex Pro 26kW Combi boiler would be a suitable installation choice 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 26kW 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.


What are the dimensions of the Grant Vortex Pro 26kW boiler?

The dimensions of the Grant Vortex Pro 26kW are 857 mm [H] x 515 mm [W] x 606 mm [D].

Many homes in the UK still have floor-standing boilers like the Grant Vortex Pro 26kW, even though wall-hung boilers have become the product of choice for most homeowners over the last 20 years. If you'd like to replace your existing floor-standing boiler with a compact, wall-mounted boiler to create more space for you and your family, please bear in mind that your pipework may need to be replaced in addition to the cost of the boiler and its installation.

Savings on your oil bills will eventually completely pay for the one-time investment but it will take a few years.

Replacing an existing heat only or system boiler with the Grant Vortex Pro 26kW will also require our fitters to remove and dispose of your hot water cylinder/expansion tank.

Please contact PlumbProud for more information and guidance on the right course of action for you.

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

Because of their increased energy efficiency, we recommend to all customers that they select one of the latest condensing boilers. Condensing boilers capture the heat from water vapour condensation and flue exhaust gases and recycle that heat to warm water entering the boiler (for example, from your radiators).

The Grant Vortex Pro 26kW is a condensing oil boiler and choosing this model will result in a likely substantial reduction in your fuel bills, particularly if you're replacing an older, inefficient, non-condensing boiler.

What energy efficiency ratings have been awarded to the Grant Vortex Pro 26kW combi?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Would choosing a Grant Vortex Pro 26kW combi help in the fight against climate change? What do the performance statistics suggest?

By law, boilers manufactured and supplied in the UK must achieve a SEDBUK rating of "A" and work at a 92% minimum efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Grant Vortex Pro 26kW was given an efficiency rating of 90% with a SEDBUK rating of "A".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

The Energy Related Products Directive (ERP) intends to reduce the amount of energy consumed by individual products over their entire lifetime, from the initial manufacturing process to final disposal and at all points in between.

The legislation is designed to encourage manufacturers to create products that are more environmentally friendly and which result in a reduction in harmful gas emissions.

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

If the Grant Vortex Pro 26kW combi boiler breaks down, am I covered?

The Grant Vortex Pro 26kW boiler is provided with a parts and labour warranty lasting 2 years.

Grant Vortex Pro 26kW Combi Oil boiler frequently asked questions

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

You might want to consider the Grant Vortex Pro 26kW for your house or flat if you are looking for a combi boiler.

Traditional boilers would require you to install one or more storage tanks in your property. These tanks either kept the water warm or stored it for later heating. Manufacturers initially designed and introduced combi boilers to the market to offer homeowners the highest levels of warmth and unlimited hot water without taking up as much space.

Combi boilers provide hot water on demand for your radiators and taps. They take water directly from the mains, heat it immediately as it's needed, and then distribute the hot water around your home.

Combi boilers, however, are limited in terms of how much water they can heat at any given time. For example, if one person wishes to take a shower while another wants to turn on a hot water tap, the amount of water reaching each point drops. This results in a drop in the water pressure as well as the temperature.

Is a Grant Vortex Pro 26kW combi the right boiler for my house or flat?

Selecting the right boiler for your home means choosing 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".

Your boiler’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your oil than you need to.

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

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

The Grant Vortex Pro 26kW is 857 mm tall, 515 mm wide, and 606 mm deep.

If you use a floor-standing boiler like the Grant Vortex Pro 26kW for your central heating and you're interested in replacing it with a more compact, wall-mounted boiler, you can. Wall-mounted boilers have been the most popular choice over the last two decades among homeowners wanting to create more space within their properties. Bear in mind that, while wall-mounted units are cheap, you may have to pay more for installation if your current piping needs replacing because it's not compatible with your new system.

This additional cost would however be recouped in full over a few years because of the savings you make on your quarterly oil bills.

Please bear in mind that replacing your existing system or heat only boiler with the Grant Vortex Pro 26kW will also involve the removal of your hot water cylinder and/or cold water tank.

If you would like further guidance, please contact PlumbProud for free support.

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

We recommend that, if possible, you choose a condensing boiler like the Grant Vortex Pro 26kW.

Condensing boilers are more energy-efficient. They achieve this efficiency by capturing the heat present in flue exhaust gases and water vapour condensation and recycling that heat to, for example, warm colder water coming back from your radiators.

By choosing the latest condensing boiler, you'll also notice a significant reduction in your oil bills, particularly if you're replacing a boiler more than 15 years old.

Is the Grant Vortex Pro 26kW combi boiler environmentally friendly?

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.

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

Would installing the Grant Vortex Pro 26kW combi in your home be an environmentally friendly decision? Let's look closely at the figures.

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The Grant Vortex Pro 26kW was awarded an efficiency rating of 90% and a band rating of "A".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

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 Vortex Pro 26kW has an ERP rating of "A" for heat and "A" for hot water production.

Does the Grant Vortex Pro 26kW combi boiler come with a warranty?

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