Grant Vortex Pro 15 System Oil boiler frequently asked questions

Is the Grant Vortex Pro 15 a combi boiler, system boiler or regular boiler?

The Grant Vortex Pro 15 is a oil system boiler.

As with a heat only boiler, a system boiler requires the installation of a hot water cylinder but they do not need a cold water tank to work. This makes them suitable choices for homeowners planning a loft conversion or for properties without a loft or very limited attic space.

The primary heating and hot water system components are built in to system boilers and you can use the control panel to set the times that you wish your heating and hot water to be available. Hot water is stored in the cylinder for use throughout the day, but if you don't set your timer, heat and hot water will not be available instantly.

A system boiler can supply multiple taps and showers simultaneously and is suitable for both large families and properties with more than one bathroom - combi boilers struggle to do this.

Is a Grant Vortex Pro 15 system the right boiler for my house or flat?

Whether this Grant Vortex Pro 15 System 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 Vortex Pro 15 system is 26 kW, so which types of property would this model be appropriate for?

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


How large is the Grant Vortex Pro 15?

The size of the Grant Vortex Pro 15 boiler is 860 mm tall, 470 mm wide, and 566 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.

Is the Grant Vortex Pro 15 a non-condensing or condensing boiler?

The Grant Vortex Pro 15 is a condensing oil boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of oil to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower oil bills) and are better for the environment.

How does the Grant Vortex Pro 15 system boiler rate environmentally?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

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 a Grant Vortex Pro 15 system help in the fight against climate change? What do the performance statistics suggest?

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The Grant Vortex Pro 15 was awarded an efficiency rating of 91.7% and a band rating of "A".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

The ERP (or Energy Related Products Directive) is a European regulation governing products which require energy to operate throughout their lives and encourages manufacturers to create products that are more environmentally friendly.

The legislation is designed to reduce the potential for harmful gas emissions during manufacturing and actual use right through to the point of final disposal.

For the Grant Vortex Pro 15, the ERP rating is "A".

Am I covered if the Grant Vortex Pro 15 system boiler breaks down?

The Grant Vortex Pro 15 boiler comes with a parts and labour warranty lasting 2 years.

Grant Vortex Pro 15 System Oil boiler frequently asked questions

Is the Grant Vortex Pro 15 boiler a combi, system or regular boiler?

Looking for a oil system boiler for your flat or house? Then the Grant Vortex Pro 15 may be an option you should consider.

As with a heat only boiler, a system boiler requires the installation of a hot water cylinder but they do not need a cold water tank to work. This makes them suitable choices for homeowners planning a loft conversion or for properties without a loft or very limited attic space.

The primary heating and hot water system components are built in to system boilers and you can use the control panel to set the times that you wish your heating and hot water to be available. Hot water is stored in the cylinder for use throughout the day, but if you don't set your timer, heat and hot water will not be available instantly.

A system boiler can supply multiple taps and showers simultaneously and is suitable for both large families and properties with more than one bathroom - combi boilers struggle to do this.

Is the Grant Vortex Pro 15 system boiler a suitable choice for my property?

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 15 System 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 15 system boiler has an output level of 26 kW, so which types of property would it be appropriate for?

An experienced Gas Safe boiler installer would be likely to recommend that this Grant Vortex Pro 15 System 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.


How large is the Grant Vortex Pro 15?

The measurements of the Grant Vortex Pro 15 are 860 mm by 470 mm by 566 mm.

Hundreds of thousands of properties still have floor-standing boilers like the Grant Vortex Pro 15 in the UK, although wall-hung boilers are now the obvious choice for most homeowners wanting more living space. It is possible to replace your existing floor-standing boiler with one that is compact if you'd like to but you should consider that much of the pipework will need to be replaced in addition to the cost of the boiler and its installation.

Eventually, your savings on oil bills will pay for the one-time investment but it will take a few years.

Is the Grant Vortex Pro 15 a condensing or non-condensing boiler?

We recommend that, if possible, you choose a condensing boiler like the Grant Vortex Pro 15.

Condensing boilers are more energy-efficient. They achieve this efficiency by capturing the heat present in flue exhaust gases and water vapour condensation and recycling that heat to, for example, warm colder water coming back from your radiators.

By choosing the latest condensing boiler, you'll also notice a significant reduction in your oil bills, particularly if you're replacing a boiler more than 15 years old.

Is the Grant Vortex Pro 15 system an energy-efficient boiler?

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.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Is the Grant Vortex Pro 15 system boiler an environmentally friendly choice for your home? Here’s what the figures say.

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 Vortex Pro 15 was given an efficiency rating of 91.7% and a 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 their 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 Vortex Pro 15 has a rating of "A".

What is the warranty period for the Grant Vortex Pro 15?

You receive a parts and labour warranty of 2 years with the Grant Vortex Pro 15 boiler.
