Grant Vortex Pro 36 Combi Oil boiler frequently asked questions

Grant Vortex Pro 36 - combi, system or regular boiler?

If you’re looking for a combi boiler for your house or flat, you may wish to the consider the Grant Vortex Pro 36.

Traditional boilers have one or more large tanks in which they store either heated water or water to be heated later. Manufacturers originally introduced combi boilers to the market in the 1970s to enable homeowners to save space - UK residential properties are among the smallest in the Western world.

Combi boilers don't need these tanks because they draw water directly from the mains and instantly heat it on demand thanks to the technology inside the boiler. Combi boilers then distribute this hot water to your home’s taps and radiators when needed.

The most significant disadvantage of combi boilers is that they are not ideal in larger homes where multiple people might want hot water at the same time – for example, if someone is having a shower while another wants to wash dishes in the kitchen. This is because combi boilers have a maximum volume of water that they can heat. When two people want hot water at the same time, the water temperature, pressure and volume delivered to both points drop.

Is a Grant Vortex Pro 36 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.

Your boiler's output indicates the maximum amount of power available to it to heat the water you need to warm your radiators or when you want hot water from your taps. A higher output rate means that your boiler is capable of heating greater volumes of water.

If a boiler's output rate is too low, you'll often find that the water is not as hot as you want it to be. Too high, however, and you'll end up paying more for your oil than you should be.

The Grant Vortex Pro 36 combi boiler has an output rate of 36 kW, so which types of property would this be suitable for?

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

With combi boilers like the Grant Vortex Pro 36, 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 Vortex Pro 36 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.


How large is a Grant Vortex Pro 36 boiler?

The Grant Vortex Pro 36 is 860 mm in height, 614 mm in width and 606 mm in depth.

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.

If you replace an existing heat only or system boiler with the Grant Vortex Pro 36, you will also need to remove your hot water cylinder and/or expansion tank.

Please contact PlumbProud for information and guidance on the best course of action.

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

This Grant Vortex Pro 36 is a condensing oil boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your oil bills as well as benefitting the wider environment.

Is the Grant Vortex Pro 36 combi environmentally friendly?

As more of us are increasingly concerned about climate change, how we heat our homes and its impact on the environment has become an issue of importance to homeowners.

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Let's take a closer look at whether installing a Grant Vortex Pro 36 combi would be a good choice for the environment.

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 36 was given an efficiency rating of 94.5% 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 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 Vortex Pro 36 are "A" for heat and "A" for hot water.

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

The Grant Vortex Pro 36 boiler has a warranty covering parts and labour costs for up to 2 years after installation.

Grant Vortex Pro 36 Combi Oil boiler frequently asked questions

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

If you are considering installing a combi boiler in your house or flat, then the Grant Vortex Pro 36 boiler is certainly worth investigating.

Traditionally, most boilers required you to find space in your property for one or more large storage tanks. These tanks would either keep water warm or hold it in reserve for later heating. Manufacturers originally introduced combi boilers to offer homeowners the same level of warmth and hot water without taking up as much space – remember that the UK has some of the smallest homes in the Western world.

With a combi boiler, the hot water needed for your radiators and taps is provided on demand. Water from the mains passes through your combi boiler and the technology within it instantly heats the cold water. It then distributes that hot water around your home.

The biggest drawback for combi boilers is that they have a maximum capacity in volume for heating water. This means that if someone wants to use the shower while another person wants to use a hot water tap, the amount of water reaching each point falls, resulting in a drop in water pressure.

Is a Grant Vortex Pro 36 combi boiler suitable for my house or apartment?

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 Vortex Pro 36 combi is 36 kW, so which types of property would this Grant Vortex Pro 36 Combi boiler be appropriate for?

A PlumbProud heating engineer would recommend that this Grant Vortex Pro 36 Combi boiler be installed in larger properties including detached homes with 15 or more radiators and two or more bathrooms.

Flow rates are important when choosing a combi boiler as well as output rates.

A combi boiler's flow rate (measured in litres per minute) describes how much water it can instantly heat then distribute to the taps and radiators in your home - you will need to factor this into your decision on a new combi boiler. This Grant Vortex Pro 36 Combi boiler's flow rate is 20 L/m.

If you have a lot of radiators and bathrooms in your home and there's lots of demand within your household for hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate.

However, it's not quite that simple. If your local mains water pressure is low, you're not going to gain any benefit from choosing a combi boiler with a high flow rate because that higher flow rate 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.


The size of the Grant Vortex Pro 36 in millimetres

The dimensions of the Grant Vortex Pro 36 are 860 mm tall, 614 mm wide, and 606 mm deep.

Wall-hung boilers have been the most popular installation choice over the last 20 years because they're compact, discreet, and don’t take up much space. Yet there are still hundreds of thousands of UK homeowners whose central heating is provided by floor-standing boilers like the Grant Vortex Pro 36, which they're looking to replace to free up more living space. This is possible, however please be aware that there may be an additional cost if we need to replace your existing pipework.

That said, you should be able to fully recoup your investment within a few years thanks to the quarterly savings you'll make on your oil bills.

It is also important to keep in mind that if you plan to replace an existing heat only or system boiler with the Grant Vortex Pro 36, your hot water cylinder and/or expansion tank will need to be removed.

Feel free to contact PlumbProud for information and guidance and we'll be happy to provide it.

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

The Grant Vortex Pro 36 is a condensing oil boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

Is the Grant Vortex Pro 36 combi an environmentally friendly boiler?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Will choosing to install a Grant Vortex Pro 36 combi in your home help the environment? Let's review the figures.

The energy efficiency rating for a boiler describes the amount of energy it uses and wastes during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "B" SEDBUK rating, 90%+ = "A" SEDBUK rating).

The Grant Vortex Pro 36 scored an efficiency rating of 94.5% and a SEDBUK band rating of A.

The Energy Related Products Directive grades products according to the energy they consume and the harmful gas emissions they create, from manufacturing right through to final disposal, including how they're used by customers between these two points.

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

Am I covered if my Grant Vortex Pro 36 combi boiler breaks down?

The Grant Vortex Pro 36 boiler comes with a parts and labour warranty lasting 2 years.
