Grant VortexBlue 36kW Combi Oil boiler frequently asked questions

What type of boiler is the Grant VortexBlue 36kW - regular, system or combi?

If you want a combi boiler for your flat or house, the Grant VortexBlue 36kW might be an option for you to consider.

Traditional boilers need one or more large tanks to work - one to heat and keep water warm for immediate use and the other to store water intended for heating later. Finding space for these large tanks is difficult in British residential property - remember that our houses and flats are among the smallest in the world. This is the problem that combi boilers were designed to solve when they were introduced in the 1970s.

Combi boilers don't need a tank - instead, they instantly heat water drawn from the mains using technology inside the boiler. This hot water is then distributed immediately to your taps or radiators on demand.

The biggest disadvantage to combi boilers is that they have a maximum capacity for heating water, meaning that they work best when only one point within a household wants hot water. For example, if someone is taking a shower and another person uses a hot water tap at the same time, the water pressure, volume and temperature to both points drops.

Should I choose a Grant VortexBlue 36kW combi boiler for my house or flat?

Whether this Grant VortexBlue 36kW Combi boiler is right for where you live depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.

A boiler whose output is too high will give you hot water and warm radiators but also higher oil bills, whereas a boiler whose output is too low will result in cheaper oil bills but the water might not always be as hot as you want it to be.

The output of the Grant VortexBlue 36kW combi is 36 kW, so which types of property would this model be appropriate for?

Most experienced Gas Safe boiler installers would recommend this Grant VortexBlue 36kW Combi boiler as a suitable option for larger properties including detached homes with no more than 15 or more radiators and two or more bathrooms.

If you are thinking about installing a combi boiler like the Grant VortexBlue 36kW in your home, you should consider flow rates as well as output rates. This Grant VortexBlue 36kW Combi boiler's flow rate is 20 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 VortexBlue 36kW

The Grant VortexBlue 36kW boiler measures 945 mm [H] x 658 mm [W] x 966 mm [D] in size.

An external, floor-standing combi boiler like the Grant VortexBlue 36kW frees up valuable space in your home and is easier for an engineer to access when it needs servicing or repair.

They benefit from solid and reliable waterproof housing which protect them from the worst of the British climate as well as from water ingress and rusting.

Internal oil boilers can leak and damage your property. An external boiler limits both the potential for damage as well as the unpleasant odours which result after a leak.

VortexBlue 36kW – condensing or non-condensing?

We recommend that you choose a condensing boiler wherever possible like the Grant VortexBlue 36kW - try to go for the latest model, if possible, to take advantage of improving technology.

Condensing boilers capture and recycle the warmth still present in the water vapour condensation and in flue exhaust emissions created by burning oil to make them more efficient and economical to run.

You will save money on your oil bills too, plus condensing boilers are friendlier to the environment.

Is the Grant VortexBlue 36kW combi boiler rated as environmentally friendly?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British homeowners.

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Will installing a Grant VortexBlue 36kW combi in your home be a positive contribution to the environment? The figures below will tell you more.

All boilers manufactured and installed in the UK are required by law to have an energy efficiency rating of at least 92%, equivalent to a good “A” rating on the SEDBUK scale. Before this, the minimum was 88% (ratings of 88% and 89% are equivalent to a high “B” SEDBUK rating and anything 90% or higher is an "A" rating).

A boiler's energy efficiency rating is designed to let you know how much energy is used and wasted during normal functioning.

The Grant VortexBlue 36kW was given an efficiency rating of 94.5% and a band rating of "A".

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 VortexBlue 36kW, the ERP Heat rating is "A" and the ERP Water rating is "A".

How long is the warranty period on a Grant VortexBlue 36kW combi boiler?

Parts and labour charges incurred during a repair on the Grant Grant VortexBlue 36kW boiler are covered by a 2 year warranty.

Grant VortexBlue 36kW Combi Oil boiler frequently asked questions

Is the Grant VortexBlue 36kW a combi boiler, system boiler or regular boiler?

The Grant VortexBlue 36kW boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

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.

Would the Grant VortexBlue 36kW combi be a suitable boiler for my house or flat?

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

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for oil than you need to.

The output of the Grant VortexBlue 36kW combi is 36 kW, so which types of property would this Grant VortexBlue 36kW Combi boiler be appropriate for?

Most Gas Safe engineers would suggest that the Grant VortexBlue 36kW combi boiler would be a suitable choice for installation in larger properties including detached homes with 15 or more radiators and two or more bathrooms.

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 VortexBlue 36kW Combi boiler's flow rate is 20 L/m.

As with all combi boilers, the Grant VortexBlue 36kW 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 is the size of the Grant VortexBlue 36kW?

The Grant VortexBlue 36kW is 945 mm in height, 658 mm in width and 966 mm in depth.

External, floor-standing combi boilers like the Grant VortexBlue 36kW provide homeowners with more indoor space (they're installed outdoors) and reduce noise pollution (you can't really hear them from inside your house). They are also easier for engineers to work on if needed, while carbon monoxide leaks are less likely to pose a safety threat to your family because the gas disperses outside.

This model's weatherproof housing ensures protection from the British climate, reducing the likelihood of water ingress and rusting. And, since the oil is stored outdoors, there is minimal risk of leakage occurring inside your home that can cause significant damage as well as unpleasant odours which are hard to eliminate.

Is the Grant VortexBlue 36kW a condensing or non-condensing boiler?

Condensing oil boilers like the Grant VortexBlue 36kW 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 VortexBlue 36kW combi rated as environmentally friendly?

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.

With central heating being responsible for 14% of greenhouse gas emissions in the UK, your choice of boiler matters. Gas boilers are also responsible for the significant atmospheric volumes of dangerous nitrogen dioxide emissions in larger British cities.

Will you be helping the environment if you decide to install a Grant VortexBlue 36kW combi in your home? Let’s look at the figures.

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Grant VortexBlue 36kW was awarded an efficiency rating of 94.5% with a SEDBUK grading of "A".

The Energy Related Products (ERP) Directive is a European directive which applies to all products that consume energy over their lifetime.

It encourages companies to create products that are environmentally friendlier at all life cycle stages, including initial manufacturing and end use through to final disposal, with the aim of reducing harmful gas emissions.

The Grant VortexBlue 36kW is rated "A" for heat and "A" for water.

What warranty does the Grant VortexBlue 36kW combi boiler come with?

The Grant VortexBlue 36kW boiler offers a parts and labour warranty of 2 years.
