Grant Vortex Eco 21-26kW System Oil boiler frequently asked questions

Grant Vortex Eco 21-26kW - a regular boiler, combi boiler or system boiler?

The Grant Vortex Eco 21-26kW boiler is a system boiler you may wish to consider when looking for a new boiler for your house or flat.

For homes that have a higher-than-average demand for hot water and heating and for larger properties, system boilers are a more suitable option than the more popular combi boilers.

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.

And, unlike heat only boilers that also require a cold water storage tank to work (normally fitted in the loft), system boilers don't, meaning they're quicker, easier and cheaper to install.

Is the Grant Vortex Eco 21-26kW system boiler a suitable option for my house or flat?

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 21-26kW system boiler has an output rate of 21 kW, so which types of property would this be suitable for?

A PlumbProud Gas Safe boiler installer would recommend that the level of output from this Grant Vortex Eco 21-26kW System boiler would make it a suitable installation option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


How large is a Grant Vortex Eco 21-26kW boiler?

The Grant Vortex Eco 21-26kW measures 908 mm in height by 505 mm in width by 800 mm in depth.

External, floor-standing system boilers like the Grant Vortex Eco 21-26kW provide homeowners with more indoor space (they're installed outdoors) and reduce noise pollution (you can't really hear them from inside your house). They are also easier for engineers to work on if needed, while carbon monoxide leaks are less likely to pose a safety threat to your family because the gas disperses outside.

This model's weatherproof housing ensures protection from the British climate, reducing the likelihood of water ingress and rusting. And, since the oil is stored outdoors, there is minimal risk of leakage occurring inside your home that can cause significant damage as well as unpleasant odours which are hard to eliminate.

Is this Grant boiler condensing or non-condensing?

This Grant Vortex Eco 21-26kW 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 Eco 21-26kW system boiler environmentally friendly?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Would installing a Grant Vortex Eco 21-26kW system boiler in your home be a green choice? Let's look at the numbers.

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 21-26kW was awarded an efficiency rating of 90.3% with a SEDBUK band rating 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 Eco 21-26kW scores "A".

What is the length of the warranty on the Grant Vortex Eco 21-26kW?

A parts and labour warranty of 2 years is included when you purchase the Grant Vortex Eco 21-26kW boiler through PlumbProud.

Grant Vortex Eco 21-26kW System Oil boiler frequently asked questions

Grant Vortex Eco 21-26kW - a system boiler, regular boiler or combi boiler?

The Grant Vortex Eco 21-26kW boiler could be suitable for your house or flat if you are looking for a new system boiler.

System boilers are very popular for properties with limited or no loft space or when homeowners want to keep the space for a loft conversion. This is because, unlike heat only boilers, they don’t require a cold-water tank - however, system boilers do need a hot water cylinder (often installed in an airing or landing cupboard).

Instead of the traditional cold-water tanks, system boilers use their built-in circulating pumps to heat the water needed for your taps and radiators. This also makes them an easier choice for engineers to install as there is one less large component to find space for and fit.

Like a regular boiler, you need to use a control panel to control a system boiler. Set the times when you want central heating and hot water to be available, such as in the morning when there might be greater demand for showers, and it will be there. Although hot water is not available on-demand like with a combi boiler, once the water has been heated it will stay in the hot water cylinder until it’s used up.

Is the Grant Vortex Eco 21-26kW system boiler from the Vortex Eco range a suitable choice for my house or flat?

Selecting the right boiler for your home means choosing a boiler that 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’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your oil than you need to.

The Grant Vortex Eco 21-26kW system has an output of 21 kW, so which types of property would this Grant Vortex Eco 21-26kW System boiler be appropriate for?

An experienced PlumbProud boiler engineer would recommend that this Grant Vortex Eco 21-26kW System boiler be installed in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


How large is a Grant Vortex Eco 21-26kW boiler?

The Grant Vortex Eco 21-26kW measures 908 mm high and 505 mm wide by a depth of 800 mm.

The Grant Vortex Eco 21-26kW is an external floor-standing system boiler intended for placement outside the home. In addition to providing you with more indoor space and reducing noise, this makes it easier for a service technician to access it if something goes wrong. The chance of carbon monoxide leaking into your home is also greatly reduced.

Floor-standing external boilers are housed in a weatherproof covering allowing them to be placed outside your home with only a minimal risk of rusting. Using external boilers is also safer because there will be less chance of oil leaks in your home which can cause significant internal damage and leave you with an oily odour that is hard to remove.

Is this Grant boiler non-condensing or condensing?

Condensing oil boilers like the Grant Vortex Eco 21-26kW are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less oil to run.

How does the Grant Vortex Eco 21-26kW system rate environmentally?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

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 choosing a Grant Vortex Eco 21-26kW system help the environment? Let’s see what the performance figures suggest.

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 Eco 21-26kW was given an efficiency rating of 90.3% and a band rating of "A".

The Energy Related Products Directive intends to encourage all manufacturers to reduce harmful gas emissions connected to the products they make, from the manufacturing stage to final disposal, including when they are in active use.

The Grant Vortex Eco 21-26kW has an ERP rating of "A".

Is there a warranty on the Grant Vortex Eco 21-26kW system boiler if it breaks down?

The parts and labour warranty on the Grant Vortex Eco 21-26kW lasts for 2 years.
