Grant VortexBlue 36kW Combi Oil boiler frequently asked questions

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

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

Combination or combi boilers are highly efficient and save a lot of space in your home. Combi boilers heat water directly from the mains when you turn on a tap and, as a result, you don’t need a hot water storage cylinder or a cold water tank in the roof space.

These boilers are, therefore, suitable for smaller homes and especially those without a loft. They are also cost-effective as the water is heated instantly and distributed on demand rather than being stored. Combi boilers are the most popular type of boilers in the UK and replacing an older boiler with a new combi boiler will reduce your oil bills significantly.

However, there are downsides to this type of boiler. If you take a shower while someone else is using a tap, less water will reach each point of usage at lower rates of pressure and temperatures as combi boilers can only heat a certain volume of water at any given time.

Is the Grant VortexBlue 36kW combi boiler a suitable choice for my property?

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?

An experienced Gas Safe boiler installer would be likely to recommend that this Grant VortexBlue 36kW Combi boiler is capable of providing heating and hot water to 15 or more radiators and two or more bathrooms and would therefore be most suitable for larger properties including detached homes.

When choosing a combi boiler like the Grant VortexBlue 36kW, 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 VortexBlue 36kW Combi boiler's flow rate is 20 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.


What are the dimensions of the Grant VortexBlue 36kW boiler?

The Grant VortexBlue 36kW measures 900 mm in height and has a width of 614 mm and a depth of 609 mm.

Floor-standing boilers can still be found in hundreds of thousands of properties in the UK - however, many homeowners are considering switching to wall-mounted units to create new living space for themselves and their families. Our engineers can replace your current floor-standing unit with a wall-mounted model, although please be aware that we may need to charge more if your current pipework needs replacing.

Your investment will be worth it as you'll more than cover the cost with the saving you make every year 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 VortexBlue 36kW, your hot water cylinder and/or cold water tank will also have to be removed.

Please contact PlumbProud for professional information and guidance on the best course of action and we’ll share our advice with you.

VortexBlue 36kW – non-condensing or condensing?

We strongly recommend that you choose a condensing boiler like the Grant VortexBlue 36kW - 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 VortexBlue 36kW combi boiler environmentally friendly?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to many homeowners.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Would choosing the Grant VortexBlue 36kW combi help the environment? Let's see what the statistics suggest.

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Grant VortexBlue 36kW is rated as 94.5% energy efficient, equivalent to a "A" SEDBUK rating.

The ERP (Energy Related Products Directive) applies to all products that consume energy at any time in their lifetime, from manufacture to disposal and all points in between.

This European legislation intends to encourage manufacturers to offer end users products that are better for the environment through the creation of fewer harmful gas emissions at all points of a product's life cycle.

The ERP rating for the Grant VortexBlue 36kW is "A" for heat and "A" for water.

What is the warranty period for the Grant VortexBlue 36kW?

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

Grant VortexBlue 36kW Combi Oil boiler frequently asked questions

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

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.

The UK has some of the smallest homes in the Western world, which is partly why combi boilers were introduced in the 1970s. Traditional boilers require one or more large storage tanks which they use to either heat water and keep it warm or store water intended for heating later. These tanks took up a lot of space in people's homes.

Combi boilers save space because they don't require these tanks to operate. Instead, combis draw water direct from your mains supply then instantly heat and distribute it on demand.

The biggest disadvantage in using combi boilers is that they have a maximum capacity volume for heating water. While this may not be an issue in a small household, it could be for a larger household where there is higher demand for hot water. When more than one person is using the water, it is distributed between the two points, reducing the pressure and temperature at each point.

Is a Grant VortexBlue 36kW combi boiler right for my house or apartment?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Grant VortexBlue 36kW combi boiler is 36 kW kilowatts. Which types of property would this be appropriate for?

An experienced Gas Safe boiler installer would be likely to recommend that this Grant VortexBlue 36kW Combi boiler is capable of providing heating and hot water to 15 or more radiators and two or more bathrooms and would therefore be most suitable for larger properties including detached homes.

With combi boilers, you need to consider the flow rate as well as the output rate. The flow rate (shown in litres per minute) measures how much water your boiler can draw from the mains which it then instantly heats and distributes to your taps and radiators.

However, a high flow rate is of little to no value if your local water pressure is low. If your local mains water pressure is 10l/m and your flow rate is 12l/m, your boiler will only be able to process 10l/m.

If you live in an area with high water pressure but your household has multiple bathrooms and/or radiators and many members of your household want to use hot water at the same time (like morning or evening baths or showers), it's unlikely that you'll be able to find a combi with a high enough flow rate.

As an indication, a power shower needs about 10 litres of water per minute, whereas the flow rate of this Grant VortexBlue 36kW Combi boiler is 20 L/ml/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 dimensions does a Grant VortexBlue 36kW have?

The Grant VortexBlue 36kW is 900 mm tall, 614 mm wide, and 609 mm deep.

There are hundreds of thousands of properties whose central heating systems are powered by floor-standing boilers like the Grant VortexBlue 36kW. If you're considering switching from your current floor-standing to a new wall-mounted model to free up space inside your home for you and your family, we can do this work for you. However, when you change the type of boiler in your home, please bear in mind that we often need to replace the piping at extra cost.

However, given the quarterly savings you'll make on your oil bills as a result of switching, you should be able to recoup your investment in full within a few years.

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 VortexBlue 36kW.

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

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

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 environmentally friendly?

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.

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.

Do the figures suggest that installing the Grant VortexBlue 36kW combi at your property would help in the fight against climate change?

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

Following its assessment, the Grant VortexBlue 36kW was given an efficiency rating of 94.5% and a SEDBUK grading of "A".

In 2015, the Energy Related Products Directive (ERP) came into force. The legislation applies to all products that consume energy in production, during their active life, and at the point of final disposal.

The ERP was introduced to incentivise manufacturers to create products that emitted fewer harmful gases with the larger aim of protecting the wider environment.

The Grant VortexBlue 36kW has been awarded an ERP rating of "A" for heat and "A" for water.

Am I covered if my Grant VortexBlue 36kW combi boiler breaks down?

The manufacturer offers a parts and labour warranty of 2 years on the Grant VortexBlue 36kW boiler to new customers.
