Grant Vortex Eco 15/21 heat only Oil boiler frequently asked questions

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

The Grant Vortex Eco 15/21 is a heat only boiler you may wish to consider if you want this type of boiler for your house or flat.

If your home has more than one bathroom or you have a large family that uses a lot of hot water, a heat only boiler (sometimes called a regular boiler, a conventional boiler or a standard boiler) is likely to be the best option for you. Heat only boilers require both a hot water or immersion cylinder and a cold water tank. Once the water in the cylinder is heated, you can use this hot water throughout the day and it can feed multiple taps and showers at the same time.

This is in contrast to a combi boiler which can only heat a limited amount of water at any one time. This can cause a problem if two or more taps and showers are being used simultaneously as the temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you wish heat and hot water to be available. However, if you forget to do this and the immersion cylinder is empty, you may have to wait up to an hour before hot water becomes available again.

If your property already has a water tank and cylinder, it will nearly always be cheaper to replace like for like and not choose a different type of boiler. In addition to new pipework, you may need to replace older radiators that may be unable to cope with the higher water pressure delivered by other types of boiler.

Should I install a Grant Vortex Eco 15/21 heat only boiler in my home?

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".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Grant Vortex Eco 15/21 heat only boiler is 21 kW kilowatts. Which types of property would this be appropriate for?

An experienced Gas Safe boiler installer would recommend that the Grant Vortex Eco 15/21 heat only boiler would be an ideal installation option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Grant Vortex Eco 15/21 size

The size of the Grant Vortex Eco 15/21 boiler is 860 mm high, 430 mm wide, and 605 mm deep.

If you use a floor-standing boiler like the Grant Vortex Eco 15/21 for your central heating and you're interested in replacing it with a more compact, wall-mounted boiler, you can. Wall-mounted boilers have been the most popular choice over the last two decades among homeowners wanting to create more space within their properties. Bear in mind that, while wall-mounted units are cheap, you may have to pay more for installation if your current piping needs replacing because it's not compatible with your new system.

This additional cost would however be recouped in full over a few years because of the savings you make on your quarterly oil bills.

Is the Grant Vortex Eco 15/21 a non-condensing or condensing boiler?

Condensing oil boilers like the Grant Vortex Eco 15/21 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.

Is the Grant Vortex Eco 15/21 heat only environmentally friendly?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.

Let's take a closer look at whether installing a Grant Vortex Eco 15/21 heat only would be a good choice for the environment.

All boilers manufactured in the UK from April 2018 must achieve a SEDBUK “A” grade and an energy efficiency rating of 92% or above. Before that, the minimum was 88% - efficiency ratings of 88% and 89% were scored a “B” and 90%+ an "A".

A boiler's energy efficiency rating describes how much energy it uses and wastes during its standard operation.

The energy efficiency of the Grant Vortex Eco 15/21 was rated at 92.7% with a SEDBUK grading 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 15/21 is "A".

How long is the warranty period on the Grant Vortex Eco 15/21 heat only boiler?

Parts and labour charges incurred during a repair on the Grant Grant Vortex Eco 15/21 boiler are covered by a 2 year warranty.

Grant Vortex Eco 15/21 heat only Oil boiler frequently asked questions

Which category of boiler does the Grant Vortex Eco 15/21 fit into?

When looking for a heat only boiler for your house or flat, the Grant Vortex Eco 15/21 might be a suitable option for you.

If your home has more than one bathroom or you have a large family which uses a lot of hot water, a heat only boiler (sometimes called a regular boiler, a conventional boiler or a standard boiler) is likely to be the best option for you. Heat only boilers require both a hot water or immersion cylinder and a cold water tank.

If your property already has a water tank and cylinder, it will nearly always be cheaper to replace like for like and not choose a different type of boiler. In addition to new pipework, you may need to replace older radiators that may be unable to cope with the higher water pressure delivered by other types of boiler.

Should I install a Grant Vortex Eco 15/21 heat only boiler in my house or apartment?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher oil bills.

Which types of property would this Grant Vortex Eco 15/21 heat only boiler be appropriate for given its output of 21 kW?

A boiler engineer would be likely to recommend that this Grant Vortex Eco 15/21 heat only 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.


The dimensions of the Grant Vortex Eco 15/21 are

The Grant Vortex Eco 15/21 measures 860 mm in height and has a width of 430 mm and a depth of 605 mm.

Floor-standing boilers can still be found in hundreds of thousands of properties in the UK - however, many homeowners are considering switching to wall-mounted units to create new living space for themselves and their families. Our engineers can replace your current floor-standing unit with a wall-mounted model, although please be aware that we may need to charge more if your current pipework needs replacing.

Your investment will be worth it as you'll more than cover the cost with the saving you make every year on your oil bills.

Is the Grant Vortex Eco 15/21 condensing or non-condensing?

Because of their increased energy efficiency, we recommend to all customers that they select one of the latest condensing boilers. Condensing boilers capture the heat from water vapour condensation and flue exhaust gases and recycle that heat to warm water entering the boiler (for example, from your radiators).

The Grant Vortex Eco 15/21 is a condensing oil boiler and choosing this model will result in a likely substantial reduction in your fuel bills, particularly if you're replacing an older, inefficient, non-condensing boiler.

Is the Grant Vortex Eco 15/21 heat only boiler rated as environmentally friendly?

Many homeowners are now worried about climate change and the damage they do to the environment from heating their homes has become a subject of increasing concern.

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.

Would choosing a Grant Vortex Eco 15/21 heat only help in the fight against climate change? What do the performance statistics suggest?

The Grant Vortex Eco 15/21 has been awarded an efficiency rating of 92.7% and a SEDBUK band rating of "A".

In the UK, all boilers manufactured and supplied must have an energy efficiency rating of at least 92% or a SEDBUK "A" grade. Until April 2018, the minimum rating was 88% (88% and 89% are equivalent to a SEDBUK "B" rating and anything higher is rated "A").

A boiler's energy efficiency rating describes the amount of energy it uses and wastes when in normal operation.

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use right through to final disposal.

The Grant Vortex Eco 15/21 has a rating of "A".

If the Grant Vortex Eco 15/21 breaks down, will I be covered by the warranty?

The Grant Vortex Eco 15/21 is covered by a parts and labour warranty of 2 years following installation.
