Grant Vortex Eco 15-21kW System Oil boiler frequently asked questions

Is the Grant Vortex Eco 15-21kW a system, regular or combi boiler?

If you are searching for a system boiler for your house or flat, the Grant Vortex Eco 15-21kW is certainly one to consider.

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 a Grant Vortex Eco 15-21kW system boiler suitable for my apartment or house?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your oil than you need to.

The Grant Vortex Eco 15-21kW system boiler has an output of 15 kW, so which types of property would it be most appropriate for?

Most Gas Safe engineers would suggest that the most suitable type of property for installing a Grant Vortex Eco 15-21kW system boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.


What size is a Grant Vortex Eco 15-21kW boiler?

The Grant Vortex Eco 15-21kW has the following dimensions - 860 mm high, 430 mm wide, and 605 mm deep.

Despite the increase in demand for compact, wall-mounted boilers over the last 20 years, hundreds of thousands of homes still have large floor-standing boilers like the Grant Vortex Eco 15-21kW. If you would like a wall-mounted boiler to replace your existing floor-standing unit to free up space, we can carry out this installation for you but please bear in mind that we may also need to replace your existing pipework, which will add extra costs to the work.

You should however be able to repay your investment in full within a few years with the savings you make on your oil bills.

Is this Grant boiler condensing or non-condensing?

Condensing oil boilers like the Grant Vortex Eco 15-21kW 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.

Is the Grant Vortex Eco 15-21kW system considered environmentally friendly?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to many homeowners.

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.

Would the environmental impact of installing a Grant Vortex Eco 15-21kW system in your home be positive? Let's look at the numbers.

All boilers manufactured and supplied in the UK are assigned two energy efficiency ratings. By law, they must achieve a SEDBUK "A" rating subject to a minimum efficiency level of 92%. Prior to that, the minimum was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90% and above an "A" grade).

The ratings awarded to the Grant Vortex Eco 15-21kW are 92.7% with a SEDBUK rating of "A".

In 2015, new legislation was introduced by the EU to encourage manufacturers to develop more energy-efficient products that emit fewer harmful gases throughout their lifetime.

The Energy Related Products Directive (ERP) applies to all products that consume energy, including during the manufacturing process, at the point of final disposal, and all points in between.

The ERP rating of the Grant Vortex Eco 15-21kW is "A".

Does the Grant Vortex Eco 15-21kW system boiler come with a warranty?

Grant offers a parts and labour warranty of 2 years on the Grant Vortex Eco 15-21kW.

Grant Vortex Eco 15-21kW System Oil boiler frequently asked questions

Is the Grant Vortex Eco 15-21kW boiler a standard, combi or system model?

The Grant Vortex Eco 15-21kW boiler is an option you may wish to consider if you're looking for a system boiler for your house or flat.

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.

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 a Grant Vortex Eco 15-21kW system boiler right 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 15-21kW system is 15 kW kilowatts, so which types of property would this be most suitable for?

A PlumbProud boiler engineer would recommend that this Grant Vortex Eco 15-21kW System boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


Grant Vortex Eco 15-21kW - size in millimetres

The Grant Vortex Eco 15-21kW is 860 mm high by 430 mm wide by 605 mm deep.

Hundreds of thousands of properties still have floor-standing boilers like the Grant Vortex Eco 15-21kW 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.

Vortex Eco 15-21kW – non-condensing or condensing?

We recommend that, if possible, you select one of the very latest condensing oil boilers on the market like the Grant Vortex Eco 15-21kW.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your oil bill over 5-10 years add up to more than you pay for the boiler itself.

Is the Grant Vortex Eco 15-21kW system boiler an environmentally friendly choice?

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

14% of the UK’s greenhouse gas production comes from central heating. In the bigger cities, gas boilers in particular are responsible for dangerous levels of nitrogen dioxide emissions.

Would choosing a Grant Vortex Eco 15-21kW system help in the fight against climate change? What do the performance statistics suggest?

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 15-21kW was awarded an efficiency rating of 92.7% with a SEDBUK band rating of "A".

The ERP (or Energy Related Products Directive) is European legislation which applies to all products that consume energy throughout their lifetime.

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

The ERP rating for the Grant Vortex Eco 15-21kW is "A".

What warranty do I get if I purchase the Grant Vortex Eco 15-21kW boiler?

The Grant Vortex Eco 15-21kW boiler has a warranty covering parts and labour costs for up to 2 years after installation.
