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

Is the Grant Vortex Eco 16/21 boiler a combi, regular or a system boiler?

Suitable for a house or a flat, the Grant Vortex Eco 16/21 system boiler is worth considering if you want a system boiler.

System boilers are suitable for larger homes where there is a higher-than-average demand for hot water and heating.

Through their use of a hot water cylinder, they provide hot water on demand during the day - as long as there's enough water left in the cylinder. Just let the boiler know when you want hot water for your radiators and taps via the programming panel and, subject to tank size and household usage, it'll be there for you.

Unlike heat only boilers, there is no requirement to find room in the attic for a cold water storage tank. System boilers are therefore quicker, easier and cheaper to install.

Would the Grant Vortex Eco 16/21 system be a suitable boiler for my house or flat?

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 Eco 16/21 system's output at 21 kW, which types of property would this Grant Vortex Eco 16/21 System boiler be most appropriate for?

An experienced PlumbProud heating engineer would recommend that the most suitable type of property for a Grant Vortex Eco 16/21 system would be medium-sized homes and larger apartments containing 10-15 radiators and providing hot water for 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.

Intended for wall mounting, the Grant Vortex Eco 16/21 system boiler is discreet, attractive, and functional. In contrast, floor-standing external boilers require space in or near your garden and, when you come to sell your home, this may put buyers off.

Choose the wall and the position on the wall you want this Grant Vortex Eco 16/21 System boiler installed at and our PlumbProud heating engineer will do this for you.

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

We recommend that you select a condensing boiler like the Grant Vortex Eco oil Grant Vortex Eco 16/21 for your home if possible because of the environmental benefits and the money you'll save on your oil bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning oil for reuse.

Is the Grant Vortex Eco 16/21 system an energy-efficient boiler?

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.

Do the available figures suggest that installing the Grant Vortex Eco 16/21 system in your property would be an environmentally friendly choice?

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are graded "B" and 90% and above is graded "A").

The Grant Vortex Eco 16/21 was awarded an efficiency rating of 90.5% with a SEDBUK band rating 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 to encourage manufacturers to create products that are more environmentally friendly and which reduce gas emissions associated with those products.

The ERP grading for the Grant Vortex Eco 16/21 is "A".

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

The parts and labour warranty on the Grant Vortex Eco 16/21 lasts for 2 years.

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

Grant Vortex Eco 16/21 - a combi boiler, system boiler or regular boiler?

Looking for a oil system boiler for your flat or house? Then the Grant Vortex Eco 16/21 may be an option you should consider.

If you choose a system boiler, you'll have to find somewhere to install a hot water cylinder too - they're normally located in an airing or landing cupboard. However, unlike regular boilers, they do not require a cold water tank to be fitted in the attic, making them suitable for homes with limited or no roof space or if you're planning a loft conversion in the future.

System boilers distribute the hot water to your taps and radiators using (often built-in) circulation pumps and are easier to install from scratch since they have one less component (the water tank) to consider.

System boilers also require programming to produce heat and hot water, so they cannot produce this instantly. Nonetheless, the cylinder keeps water hot for use later, so you don't have to wait as long as you set your timer and keep it on long enough to heat enough water.

Is a Grant Vortex Eco 16/21 system the right boiler for my house or flat?

Whether this Grant Vortex Eco 16/21 System boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions, however - it means how powerful it is.

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher oil bills than you need to for years to come.

The output of the Grant Vortex Eco 16/21 system is 21 kW, so which types of property is this Grant Vortex Eco 16/21 System boiler appropriate for?

A boiler engineer would be likely to recommend that this Grant Vortex Eco 16/21 System boiler is capable of providing heating and hot water to 10-15 radiators and two bathrooms and would therefore be most suitable for medium-sized homes and larger apartments.


How large is a Grant Vortex Eco 16/21 boiler?

The Grant Vortex Eco 16/21 is 837 mm in height, 635 mm in width and 350 mm in depth.

The external Grant Vortex Eco 16/21 system boiler is intended for wall mounting. For many homeowners, this is preferable to choosing a floor-standing boiler that requires you to sacrifice valuable outdoor space in or near your garden. In addition, when you come to sell your property, buyers are more likely to prefer the more discreet wall-mounted option.

If you would like to find out more about this model and which wall-mounted boilers are available, please get in touch with us and speak to one of our PlumbProud engineers.

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

We recommend that, if possible, you choose a condensing boiler like the Grant Vortex Eco 16/21.

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 Eco 16/21 system an energy-efficient boiler?

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

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.

Do the available figures suggest that installing the Grant Vortex Eco 16/21 system in your property would be an environmentally friendly choice?

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 Eco 16/21 was awarded an efficiency rating of 90.5%, equivalent to a SEDBUK grade of "A".

The Energy Related Products Directive (ERP) was introduced in 2015 and applies to all products that consume energy throughout their lifetime, including during the manufacturing process and at the point of final disposal.

The purpose of the ERP is to ensure that companies create products that are kinder to the environment by reducing both the energy they use and the harmful emissions they produce.

The Grant Vortex Eco 16/21 has an ERP rating of "A".

Does the Grant Vortex Eco 16/21 system boiler come with a warranty?

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