Grant Vortex Eco 16-21kW heat only Oil boiler frequently asked questions

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

The Grant Vortex Eco 16-21kW boiler could be suitable for your house or flat if you are looking for a new heat only boiler.

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 standard boiler, a regular boiler or a conventional 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 water temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you want 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 instead of replacing it with 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.

Would the Grant Vortex Eco 16-21kW heat only boiler be suitable 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 16-21kW heat only has an output of 21 kW, so which types of property would this Grant Vortex Eco 16-21kW heat only boiler be appropriate for?

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


Where will the Grant Vortex Eco 16-21kW fit in my house?

The size of the Grant Vortex Eco 16-21kW boiler is 837 mm tall, 635 mm wide, and 350 mm deep.

The Grant Vortex Eco 16-21kW heat only boiler is intended for wall mounting. Having a free-standing external boiler on the ground in or near your garden may put some buyers off when you try to sell your home because they would rather have that space back for recreation.

Wall mounting is becoming increasingly popular among homeowners for this reason and your PlumbProud engineer can do this for you.

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

Condensing boilers convert the warmth present in flue exhaust gases and water vapour condensation into heat which they then recycle to increase the temperature of the colder water returning to your system.

We recommend that homeowners choose a condensing boiler like the Grant Vortex Eco 16-21kW for this reason - the more recent your model the better because the technology improves every year.

You'll benefit from lower quarterly oil bills and condensing boilers are also much more environmentally friendly.

Is the Grant Vortex Eco 16-21kW heat only a good choice for the environment?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

Central heating accounts for 14% of greenhouse gas emissions in the UK. In larger British cities, gas boilers emit dangerous levels of nitrogen dioxide into the atmosphere.

Would choosing a Grant Vortex Eco 16-21kW heat only help the environment? Let’s see what the performance figures suggest.

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 16-21kW are 90.1% with a SEDBUK rating 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 16-21kW has an ERP rating of "A".

Am I covered if my Grant Vortex Eco 16-21kW heat only boiler breaks down?

The Grant Vortex Eco 16-21kW is covered by a parts and labour warranty of 2 years following installation.

Grant Vortex Eco 16-21kW heat only Oil boiler frequently asked questions

Is the Grant Vortex Eco 16-21kW a standard, combi or system boiler?

If you’re looking for a heat only boiler for your house or flat, you may wish to the consider the Grant Vortex Eco 16-21kW.

Heat only boilers, also known as conventional boilers, standard boilers or regular boilers, require a hot water/immersion cylinder and a cold-water tank to work - the immersion cylinder is usually stored in a landing or airing cupboard and the cold water tank in your attic. Your water is kept hot throughout the day by the immersion cylinder.

You can schedule your hot water and heating at set times during the day, but if you forget to set your system and there's no hot water left, you'll have to wait for the immersion cylinder to heat your water for your bath or shower.

A heat only boiler is usually a better option if you have several bathrooms in your home or yours is a large household where there may be continual demand for hot water from different family members - combi boilers are not normally a suitable choice in these situations.

Is a Grant Vortex Eco 16-21kW heat only boiler appropriate for my house or apartment?

Whether this Grant Vortex Eco 16-21kW heat only boiler is right for your property depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your oil bills than you need to.

Which types of property would this Grant Vortex Eco 16-21kW heat only boiler be appropriate for given its output of 21 kW?

Most experienced heating engineers would suggest that the most suitable type of property for installing a Grant Vortex Eco 16-21kW heat only 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 16-21kW?

The Grant Vortex Eco 16-21kW measures 837 mm tall, 635 mm wide, and 350 mm deep.

Many homeowners prefer external wall-mounted boilers over floor-standing external boilers which need a lot more room and often require you to sacrifice outside space in or near your garden. Choosing a floor-standing boiler may also put buyers off when you come to sell your property.

The Grant Vortex Eco 16-21kW heat only boiler is designed for wall mounting and your PlumbProud engineer can install it on the wall you choose.

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

The Grant Vortex Eco 16-21kW is a condensing oil boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when oil is burned to provide your boiler with power.

This means it needs less oil to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

What energy efficiency ratings have been awarded to the Grant Vortex Eco 16-21kW heat only?

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.

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Would choosing a Grant Vortex Eco 16-21kW heat only help in the fight against climate change? What do the performance statistics suggest?

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 16-21kW was rated at 90.1% with a SEDBUK grading 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 16-21kW scores "A".

Am I covered if my Grant Vortex Eco 16-21kW heat only boiler breaks down?

The Grant Vortex Eco 16-21kW boiler offers a parts and labour warranty of 2 years.
