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

What kind of boiler is the Grant Vortex Eco 15/21 - standard, combi or system?

Grant’s Vortex Eco 15/21 is one you might consider if you’re looking for a heat only 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 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 15/21 heat only be a suitable choice of boiler for my house or flat?

Selecting the right boiler for your property means selecting 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".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

The output of the Grant Vortex Eco 15/21 heat only is 21 kW kilowatts, so which types of property would this be appropriate for?

Most heating engineers would recommend this Grant Vortex Eco 15/21 heat only boiler as a suitable option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What size is a Grant Vortex Eco 15/21 boiler?

The Grant Vortex Eco 15/21 stands at 908 mm tall, 505 mm wide and 800 mm deep.

The Grant Vortex Eco 15/21 is an external floor-standing heat only boiler which will be installed outside of your home. Other than providing you with more indoor space and reduced noise, it’s much easier for a service engineer to access it if it goes wrong and there’s also a lower risk of carbon monoxide leaking into your home.

Boilers like the Grant Vortex Eco 15/21 are shielded in weatherproof housing and because the oil is outside your home, there is less chance of oil leakage, which can cause damage and odours that are hard to remove.

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

The Grant Vortex Eco 15/21 is a condensing oil boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your oil bills.

How energy efficient is the Grant Vortex Eco 15/21 heat only?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Will choosing to install a Grant Vortex Eco 15/21 heat only in your home help the environment? Let's review the figures.

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Grant Vortex Eco 15/21 has been given a rating of 92.7% for energy efficiency, equivalent to a SEDBUK "A" rating.

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from their initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

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

If the Grant Vortex Eco 15/21 heat only boiler breaks down, am I covered?

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

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

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

Looking for a oil heat only boiler for your flat or house? Then the Grant Vortex Eco 15/21 may be an option you should consider.

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.

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 15/21 heat only be a suitable choice of boiler for my house or flat?

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 15/21 heat only boiler has an output of 21 kW, so which types of property would it be most appropriate for?

An experienced boiler engineer would recommend that this Grant Vortex Eco 15/21 heat only boiler would provide adequate heating and hot water for medium-sized homes and larger apartments with up to 10-15 radiators and two bathrooms.


What are the proportions of a Grant Vortex Eco 15/21 boiler?

The size of the Grant Vortex Eco 15/21 boiler is 908 mm high, 505 mm wide, and 800 mm deep.

The Grant Vortex Eco 15/21 boiler is an external, floor-standing heat only boiler benefiting from sturdy weatherproof housing that provides reliable protection from the UK’s changeable weather, rusting, and water ingress.

Because they're installed outdoors, you save valuable space inside your home and you'll never hear the boiler in operation. An external boiler is also much easier for a service engineer to access if it breaks down or needs repair.

External boilers cut the risk of carbon monoxide leaking into your home and, because the oil it uses for power is stored outside, you greatly reduce the potential for indoor oil leakages which often cause severe damage as well as unpleasant odours that can be very hard to get rid of.

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

We recommend the Grant Vortex Eco 15/21 as it is a modern condensing oil boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more oil.

Condensing boilers significantly reduce your quarterly oil costs and they're better for the environment.

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.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

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 after April 2018 in the UK must be rated as an “A” on the SEDBUK grading system, subject to a minimum energy efficiency rating of 92% or above. Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Grant Vortex Eco 15/21 has an efficiency rating of 92.7% with a SEDBUK grade of "A".

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from their initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

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?

You receive a parts and labour warranty of 2 years with the Grant Vortex Eco 15/21 boiler.
