Grant VortexBlue 36kW Combi Oil boiler frequently asked questions

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

When looking for a combi boiler for your house or flat, the Grant VortexBlue 36kW might be a suitable option for you.

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 VortexBlue 36kW combi boiler suitable for my house or apartment?

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

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for oil than you need to.

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

Most Gas Safe boiler installers would suggest that the most suitable type of property for installing this Grant VortexBlue 36kW Combi boiler in would be larger properties including detached homes with 15 or more radiators and two or more bathrooms.

You also need to choose a combi boiler with the right flow rate for where you live.

A combi boiler's flow rate is the maximum volume of water (measured in litres per minute) that it can heat and distribute to your radiators, taps and showers at the same time. This Grant VortexBlue 36kW Combi boiler's flow rate is 20 L/m.

However, combi boilers like the Grant VortexBlue 36kW draw water directly from the mains and heat it instantly.

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.

Combi boilers also struggle when multiple people in your home want to use hot water at the same time - for example, someone running the hot water tap in the kitchen and two people wanting to shower in separate bathrooms.

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 VortexBlue 36kW are

The Grant VortexBlue 36kW boiler measures 900 mm [H] x 614 mm [W] x 609 mm [D] in size.

Many homeowners still have floor-standing boilers like the Grant VortexBlue 36kW even though wall-mounted boilers have been the preferred choice because of their compact size. If you want to replace your existing boiler with a compact wall-hung one to free up extra living space for you and your family, we can do this for you but please be aware that we may need to replace much of your existing pipework, which will incur an additional charge.

However, given the efficiency of modern wall-mounted oil boilers, the savings you make on your energy bills over the coming years should more than repay the cost of your investment.

If you're considering replacing your existing heat only or system boiler with the Grant VortexBlue 36kW, you will also need to remove the hot water cylinder and/or expansion tank.

For information and guidance on the best course of action, please contact PlumbProud and we'll share our thoughts.

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

Condensing boilers convert the warmth present in flue exhaust gases and water vapour condensation into heat which they then recycle to increase the temperature of the colder water returning to your system.

We recommend that homeowners choose a condensing boiler like the Grant VortexBlue 36kW for this reason - the more recent your model the better because the technology improves every year.

You'll benefit from lower quarterly oil bills and condensing boilers are also much more environmentally friendly.

Is the Grant VortexBlue 36kW combi environmentally friendly?

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they heat their homes.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Is the Grant VortexBlue 36kW combi boiler an environmentally friendly choice for your home? Here’s what the figures say.

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

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

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from the initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The Grant VortexBlue 36kW has a rating of "A" for heat and "A" for water.

How long is the warranty offered by the manufacturer for the Grant VortexBlue 36kW boiler?

A parts and labour warranty of 2 years is included with the Grant Grant VortexBlue 36kW boiler.

Grant VortexBlue 36kW Combi Oil boiler frequently asked questions

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

When looking for a combi boiler for your house or flat, the Grant VortexBlue 36kW might be a suitable option for you.

In many properties, combi boilers are more suitable than traditional types of boiler. Combi boilers heat water instantly on demand, which they draw directly from the mains supply, removing the need for storage tanks that can take up valuable space in your home.

A combi boiler is often the right choice for a smaller property, particularly if your home doesn't have a useable loft. As water is heated and delivered immediately rather than being kept warm for hours in an immersion tank, combi boilers reduce oil usage, thereby minimising your heating costs.

The main disadvantage of combi boilers is that they can only heat a certain amount of water at any one time. This means that, if two people are using different taps or showers within your home at the same time, the flow of heated water to each will be reduced, as will the water pressure and temperature.

Is a Grant VortexBlue 36kW combi boiler suitable for my house or flat?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

The output of a boiler is measured in kilowatts and tells you how much power it has available to heat the water it sends to your hot taps, showers and radiators. The greater the demand for hot water in your home, the larger the output you will need.

It is important to select a boiler with the optimal output rate. Choose one with too high an output and your oil bills will be too expensive. Choose one with too low an output and sometimes the water in your radiators and coming out of your taps will be barely lukewarm.

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

A heating engineer would recommend that this Grant VortexBlue 36kW Combi boiler would provide adequate heating and hot water for larger properties including detached homes with up to 15 or more radiators and two or more bathrooms.

With combi boilers like the Grant VortexBlue 36kW, you need to take the flow rate into account as well as the output rate.

Combi boilers draw water from the mains and then instantly heat that water and send it to wherever in your home it's needed. Flow rates, measured in litres per minute, are subject to the mains water pressure in your area. So, for example, if the local mains water pressure is 11 litres per minute and the flow rate of your boiler is 14 litres per minute, the boiler will not be able to process more than 11 litres per minute. The flow rate of this Grant VortexBlue 36kW Combi boiler is 20 L/m.

If you live in a home with lots of radiators or bathrooms where many people want to use hot water at the same time, a combi boiler may not be able to cope. For reference, a power shower uses about 10 litres of water per minute. If two people want showers at the same time or one person wants a shower and the other hot water from a tap in the kitchen, your boiler may not have a large enough flow rate even if the local mains water pressure is high.

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 900 mm [H] x 614 mm [W] x 609 mm [D] in size.

If you want to replace your floor-standing boiler with a more compact, wall-mounted model, this will give you and your family more space. Hundreds of thousands of homes in the UK still use floor-standing boilers like the Grant VortexBlue 36kW, but wall-mounted models have been the most popular choice for homeowners over the last two decades. We can replace your floor-mounted unit with a wall-mounted unit, but please be aware that the cost of installation will be higher if we need to replace your current piping.

However, you can recoup this investment in full over a few years with the savings you make on your oil bills.

If you are considering replacing your current heat only or system boiler with the Grant VortexBlue 36kW, please be aware that this will involve removing your hot water cylinder and/or expansion tank.

For guidance and further information, please contact the team at PlumbProud who will be happy to help you make the right choice.

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

The Grant VortexBlue 36kW is a condensing oil boiler - we strongly recommend that you choose one of the latest condensing models if possible.

With a condensing boiler, you save money on your oil bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

Is the Grant VortexBlue 36kW combi boiler an environmentally friendly choice?

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

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

Is the Grant VortexBlue 36kW combi an environmentally friendly choice for your home? Let’s have a look at the figures.

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

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

The ERP (Energy Related Products Directive) is European legislation that aims to reduce the use of energy at all points during a product's life, from the point of manufacture to when it's in active use right through to final disposal.

The regulation aims is to encourage manufacturers to create products that are more environmentally friendly and which reduce the harmful gas emissions associated with those products.

The ERP gradings for the Grant VortexBlue 36kW are "A" for heat and "A" for hot water.

Is this Grant VortexBlue 36kW combi covered by a warranty?

A parts and labour warranty of 2 years is included with the Grant Grant VortexBlue 36kW boiler.
