Grant Vortex Pro 36 Combi Oil boiler frequently asked questions

Is the Grant Vortex Pro 36 a standard, combi or system boiler?

The Grant Vortex Pro 36 may be worth considering if you are looking for a combi 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 Vortex Pro 36 combi boiler right for my house or apartment?

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 36 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 36 combi boiler has an output level of 36 kW, so which types of property would it be appropriate for?

An experienced PlumbProud Gas Safe boiler installer would almost certainly recommend that this Grant Vortex Pro 36 Combi boiler would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.

As well as the output rate, you need to consider "flow rate" when choosing a combi boiler.

The flow rate describes how much water a combi boiler can draw from the mains, instantly heat, and then send to your radiators. Flow rates are measured in litres per second and this Grant Vortex Pro 36 Combi boiler's flow rate is 20 L/m.

The water in your mains pipe also has its own flow rate - normally between 10 and 12l/m in most parts of Britain. This means that, if you choose a combi boiler with a flow rate of 17l/m where local water pressure is 11lm, it won't actually process more water because of the slower flow rate of the mains.

In addition, larger households with more than one bathroom, multiple radiators, and where family members may want to use hot water at the same time (like morning showers) may actually need a boiler with a higher flow rate than either the boiler or the local mains pipe.

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 36 dimensions

The Grant Vortex Pro 36 measures 860 mm in height and has a width of 614 mm and a depth of 606 mm.

Over the last 20 years, compact wall-hung boilers have been installed in far greater numbers in UK properties than floor-standing boilers like the Grant Vortex Pro 36. While hundreds of thousands of properties still have floor-standing boilers, many homeowners consider making the switch to wall-hung boilers to increase the amount of living space that they and their families can enjoy. We can swap your old floor-standing boiler for a wall-mounted boiler but please bear in mind that there may be an additional cost for your installation if we have to replace the pipework.

You should though be able to recoup this investment in full in just a few years with the savings you make on your oil bills.

Please be aware that if you replace your existing heat only or system boiler with the Grant Vortex Pro 36, you'll also need to remove your hot water cylinder and/or expansion tank.

Please contact PlumbProud for further advice if you are unsure how to proceed. Our friendly team will be happy to assist you in making the right decision.

Vortex Pro 36 – non-condensing or condensing?

The Grant Vortex Pro 36 is a condensing oil boiler - in fact, we recommend that you select this model or one of the latest condensing boilers on the market as the technology continues to improve over time.

Condensing boilers capture the heat still present in the flue exhaust gases and water vapour condensation created when the oil is burned and they recycle this back into the heating system to warm up the cold water re-entering the boiler from your radiators.

They're much more environmentally friendly and installing one results in much lower annual oil bills.

Is the Grant Vortex Pro 36 combi good for the environment?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

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

Boilers manufactured in the UK must be tested and, by law, achieve an energy efficiency rating of 92% or above, equivalent to a SEDBUK "A" grade. Most boilers achieve an "A" rating meaning they are at least 88% efficient.

The energy efficiency of a boiler indicates the amount of energy it uses (and wastes) during operation.

The Grant Vortex Pro 36 has been assigned an efficiency rating of 94.5% with a SEDBUK rating of "A".

The Energy Related Products Directive (ERP) is European legislation that applies to all products which use or consume energy during their lifespan, including during the manufacturing process and when they're in actual use, right through to the point of final disposal.

The aim is to encourage manufacturers to create new products that are kinder to the environment and create fewer harmful gas emissions.

The Grant Vortex Pro 36 has an ERP Heat rating of "A" and an ERP Water rating of "A".

How long is the warranty period on the Grant Vortex Pro 36 combi boiler?

The Grant Vortex Pro 36 is supplied with a parts and labour warranty of 2 years.

Grant Vortex Pro 36 Combi Oil boiler frequently asked questions

What type of boiler is Grant’s Vortex Pro 36 - system, regular or combi?

Suitable for a house or a flat, the Grant Vortex Pro 36 combi boiler is worth considering if you want a combi boiler.

Traditionally, boilers needed one or more large tanks installed in your property to store their heated water or water that was to be heated later. These tanks were often too large to be practical for most homes so the combi boiler was introduced to Britain in the 1970s by manufacturers to help homeowners overcome this issue.

Instead of using tanks as storage, a combi boiler heats water on demand. It draws water from the mains and heats it instantly on demand before distributing it to wherever it is needed in a property, be it your taps or radiators.

Unfortunately, combi boilers have one main disadvantage for larger properties or larger households. Because they have a maximum volume of water that can be heated on demand at any given time, water pressure, volume and temperature will drop if, for example, someone is taking a shower and another person in your home wants to use a hot water tap at the same time.

Is a Grant Vortex Pro 36 combi boiler appropriate 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 36 combi's output at 36 kW, which types of property would this Grant Vortex Pro 36 Combi boiler be most appropriate for?

A heating engineer would recommend that this Grant Vortex Pro 36 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.

When choosing a combi boiler for your home, you need to think about "flow rates" as well as output rates. This Grant Vortex Pro 36 Combi boiler's flow rate is 20 L/m.

This indicates the maximum volume of hot water (measured in litres per minute) that your boiler can heat then distribute to your taps, showers and radiators at any one time. The greater the demand for hot water in your home, the higher the flow rate you will require.

However, all combi boilers like the Grant Vortex Pro 36 draw water directly from the mains and heat it instantly.

This means that they can only heat and distribute water at the rate it enters the property (the "mains pressure" rate). For example, if your mains pressure is 11 litres per minute, this will be the highest flow rate you can achieve even if your boiler's flow rate is 17l/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 size is a Grant Vortex Pro 36 boiler?

The Grant Vortex Pro 36 measures 860 mm tall, 614 mm wide, and 606 mm deep.

Wall-hung boilers have become the preferred choice for homeowners in the UK over the last 20 years, but hundreds of thousands of homes still use bulkier floor-standing models for their central heating. It is possible to replace your floor-standing boiler with a wall-mounted one if you wish so that you and your family have more living space. But we must advise you that you may also have to pay to replace some or all of your existing pipework.

You should however be able to recoup this cost in full after a few years because of the savings you make each quarter 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 Vortex Pro 36, 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.

Is the Grant Vortex Pro 36 condensing or non-condensing?

The Grant Vortex Pro 36 boiler is a condensing oil boiler and we recommend that you select one of the latest models if possible.

Condensing boilers reduce homeowners' oil bills and are better for the environment. They do this by capturing and recycling the heat still present in the flue exhaust gases and water vapour condensation produced when boilers burn oil to generate the power they need to operate.

Is the Grant Vortex Pro 36 combi environmentally friendly?

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.

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

Would choosing the Grant Vortex Pro 36 combi be an environmentally-friendly choice? If so, let's look at its performance figures.

All new British boilers must perform to a legal minimum energy efficiency of 92% (a low to good SEDBUK "A" rating). Prior to April 2018, the target was 88% (86-90% = SEDBUK "B" and 90%+ = SEDBUK "A").

Efficiency ratings are intended to let consumers know how much energy a boiler uses in its day-to-day activities and how much energy goes to waste.

The Grant Vortex Pro 36 was awarded an efficiency rating of 94.5%, equivalent to a SEDBUK grade of "A".

All products that consume energy throughout their lifespan must comply with the Energy Related Products (ERP) Directive.

Companies are legally obliged to reduce harmful gas emissions at all stages of a product's life cycle, from initial manufacturing right through to final disposal as well as when the product is in actual use.

The Grant Vortex Pro 36 scores "A" for heat and "A" for water.

Does the Grant Vortex Pro 36 combi boiler come with a warranty?

The Grant Vortex Pro 36 boiler offers a parts and labour warranty of 2 years.
