Grant Vortex Pro 26kW Combi Oil boiler frequently asked questions

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

Grant’s Vortex Pro 26kW is one you might consider if you’re looking for a combi 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.

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

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

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

You need to consider the flow rate as well as the output rate when choosing a combi boiler.

Flow rates, measured in litres per minute, indicate how much water your boiler can heat and distribute around your home at any given time. If your family regularly use hot water around the house at the same time and you have a lot of radiators, you should choose a boiler with a high flow rate. This Grant Vortex Pro 26kW Combi boiler's flow rate is 17 L/m.

However, you also need to consider the flow rate of your local mains water supply. Combis can only draw water from the mains as fast as the pipes can deliver it. If you choose a boiler with a 14l/m flow rate and the mains pipes into your home have a flow rate of 12l/m, your boiler won't be able to operate at full capacity. In other words, try to make sure the local water pressure and your boiler flow rates are as close as possible.

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.


How large is a Grant Vortex Pro 26kW boiler?

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

Compact wall-mounted boilers have been the models of choice for most homeowners over the last 20 years. But many thousands of properties in the UK still have a floor-standing boiler like the Grant Vortex Pro 26kW. If you're interested in switching to a wall-mounted unit to create extra space in your property, bear in mind that there might be a premium on the installation work because you may need to replace your current piping.

Newer compact boilers mean lower oil bills and you could recover the cost of your investment from those savings within a few years.

If you're considering replacing your current heat only or system boiler with the Grant Vortex Pro 26kW, please note that you'll need to budget for the removal of your hot water cylinder and expansion tank.

Vortex Pro 26kW – condensing or non-condensing?

Condensing oil boilers like the Grant Vortex Pro 26kW 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 26kW combi a good choice for the environment?

With growing concern among the public about accelerating climate change, how we heat our homes and the impact this has on the environment has become a major topic of concern for many homeowners.

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.

Would the environmental impact of installing a Grant Vortex Pro 26kW combi in your home be positive? Let's look at the numbers.

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 (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

For the Grant Vortex Pro 26kW, the ERP Heat rating is "A" and the ERP Water rating is "A".

How long is the warranty offered by the manufacturer for the Grant Vortex Pro 26kW boiler?

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

Grant Vortex Pro 26kW Combi Oil boiler frequently asked questions

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

The Grant Vortex Pro 26kW is a oil combi boiler.

In older British homes, traditional boilers required you to find room for one or more storage tanks. One tank would keep hot water warm and the other stored cold water for later heating. Manufacturers introduced combi boilers to the UK in the 1970s so that homeowners could get the warmth and hot water they needed without having to sacrifice too much valuable space – remember that residential property in this country is among the smallest in the Western world.

Combi boilers deliver hot water to your radiators and taps using water they draw directly from the mains supply. As mains water travels through a combi boiler, the technology within it heats the cold water instantly and on demand. The hot water is then distributed throughout your house.

Combi boilers have one drawback, however: they can only heat a certain amount of water within a given time. For example, if someone uses the shower and another person uses the hot water tap at the same time, water pressure drops because water reaches each point differently.

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

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

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

When choosing a combi boiler like the Grant Vortex Pro 26kW, you need to consider the "flow rate" as well as the output rate. Flow rates (measured in litres per minute) indicate the volume of hot water that the boiler can heat up and then distribute to your taps and radiators.

However, combi boilers draw water from the mains and this means they can only heat the amount of water that actually enters your property.

What this means is that, if your mains pressure is 12 litres per minute, that is your boiler's effective flow rate even if it has the capacity to process 18 litres per minute. This Grant Vortex Pro 26kW Combi boiler's flow rate is 17 L/m.

To give you an idea of the flow rate you might need, a power shower typically requires around 12 litres of water per minute and a basin tap requires 4-8 litres 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.


Grant Vortex Pro 26kW size

The Grant Vortex Pro 26kW measures 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 note that if you choose to replace your current system or heat only boiler with the Grant Vortex Pro 26kW, we'll also need to remove your hot water cylinder and/or expansion tank.

Should you require help, please contact PlumbProud as we would be happy to provide guidance.

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

Condensing boilers like the Grant Vortex Pro 26kW improve energy efficiency and reduce your annual expenditure on oil.

They do this by capturing and recycling the warmth still present in water vapour condensation and flue exhaust gases to, for example, increase the temperature of the colder water returning from your radiators.

Condensing boilers are also much better for the environment because they emit fewer greenhouse gases.

Is choosing the Grant Vortex Pro 26kW 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.

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.

Do the available figures suggest that installing the Grant Vortex Pro 26kW combi in your property would be an environmentally friendly choice?

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 26kW was awarded an efficiency rating of "90%", equivalent to a "A" rating on the SEDBUK system.

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.

Will I be covered if the Grant Vortex Pro 26kW combi breaks down?

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