Grant Vortex Eco 16/21 System Oil boiler frequently asked questions

What type of boiler is the Grant Vortex Eco 16/21 - regular, system or combi?

You might want to consider the Grant Vortex Eco 16/21 for your house or flat if you are looking for a 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 the Grant Vortex Eco 16/21 system boiler suitable for my house or apartment?

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 Vortex Eco 16/21 system is 21 kW kilowatts, so which types of property would this be most suitable for?

Most experienced heating engineers would suggest that the most suitable type of property for installing a Grant Vortex Eco 16/21 system boiler in would be medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What is the size of the Grant Vortex Eco 16/21?

The Grant Vortex Eco 16/21 is 837 mm [H] by 635 mm [W] by 350 mm [D] in size.

The Grant Vortex Eco 16/21 is a wall-mounted external system boiler. Wall-mounted boilers are much more discreet than traditional floor-standing external boilers and you don't need to sacrifice valuable outdoor space in or near your garden to situate it. In addition, it may be easier to sell your property if you choose a wall-mounted boiler over a floor-standing one.

Grant Vortex Eco 16/21 – condensing or non-condensing?

Condensing oil boilers like the Grant Vortex Eco 16/21 are more energy-efficient and choosing one for your home will cut the amount you pay every year for your oil.

They do this by capturing the heat in water vapour condensation and in exhaust gases which would normally be expelled via the flue. They then recycle that heat, returning it to the system to, among other tasks, reheat colder water that is returning to your boiler from your radiators.

How does the Grant Vortex Eco 16/21 system rate environmentally?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Would installing the Grant Vortex Eco 16/21 system in your home be an environmentally friendly decision? Let's look closely at the figures.

All boilers manufactured in the UK from April 2018 must operate at a minimum level of energy efficiency of 92% ("A" rating on the SEDBUK scale). Before that, the minimum was 88% - boilers scoring 88/89% were given a SEDBUK "B" rating and 90% or above an "A" rating.

The energy efficiency score of a boiler indicates how much energy it uses and how much goes to waste when in use.

After its assessment, the Grant Vortex Eco 16/21 was given an efficiency rating of 90.5% and a SEDBUK grading of "A".

The Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

For the Grant Vortex Eco 16/21, the ERP Heat rating is "A".

How many years does the warranty period cover on a Grant Vortex Eco 16/21 boiler?

The Grant Vortex Eco 16/21 boiler comes with a 2 year warranty for parts and labour.

Grant Vortex Eco 16/21 System Oil boiler frequently asked questions

What type of boiler is the Grant Vortex Eco 16/21?

The Grant Vortex Eco 16/21 is a system boiler you may wish to consider if you want this type of boiler for your house or flat.

System boilers are suitable for homes with a higher-than-average demand for central heating and water - for example, larger homes and larger families.

Combi boilers heat water on demand but the amount of water they can actually deliver to taps is determined by the mains water pressure, flow rate and power. System boilers instead use a hot water cylinder that stores and keeps water hot throughout the day. As long as you remember to program the times you want hot water and the cylinder still has water left in it, you should have hot water whenever you need it.

System boilers do not require a cold water storage tank either, unlike heat only boilers, meaning they're cheaper, quicker and easier to install.

Is a Grant Vortex Eco 16/21 system boiler suitable 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 Eco 16/21 system boiler has an output rate of 21 kW, so which types of property would this be suitable for?

A PlumbProud boiler engineer would almost certainly recommend that this Grant Vortex Eco 16/21 System boiler is most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


How large is the Grant Vortex Eco 16/21?

The Grant Vortex Eco 16/21 occupies a space of 837 mm high by 635 mm wide and 350 mm deep.

Intended for wall mounting, the Grant Vortex Eco 16/21 system boiler removes the requirement for homeowners to find space in or near their garden to house a floor-standing boiler. In addition, floor-standing boilers may put off a potential buyer when you come to sell your property.

Let your PlumbProud engineer know which wall and in what position you want your boiler installed and we can do it for you.

Is the Grant Vortex Eco 16/21 a condensing or non-condensing boiler?

The Grant Vortex Eco 16/21 is a condensing oil boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your oil bills.

Does the Grant Vortex Eco 16/21 system protect the environment?

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

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.

Will you be helping the environment if you decide to install a Grant Vortex Eco 16/21 system in your home? Let’s look at the figures.

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 Vortex Eco 16/21 was awarded an efficiency rating of 90.5% 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 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 Eco 16/21 has a rating of "A".

If the Grant Vortex Eco 16/21 breaks down, will I be covered by the warranty?

The Grant Vortex Eco 16/21 boiler comes with a 2 year warranty for parts and labour.
