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

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

You can program a heat only boiler (sometimes called a standard boiler, a regular boiler or a conventional boiler) to provide hot water and heating at particular times of the day. Heat only boilers consist of a cold water tank (often housed out of sight in the loft), a hot water cylinder with an immersion heater (normally situated in an airing or landing cupboard), and a control panel.

Regular boilers are best suited for large households with many members, at least two of whom often need hot water at the same time.

Is a Grant Vortex Eco 15/21 heat only a suitable choice 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?

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.


How large is the Grant Vortex Eco 15/21?

The dimensions of the Grant Vortex Eco 15/21 are 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.

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

Condensing boilers like the Grant Vortex Eco 15/21 improve energy efficiency and reduce your annual expenditure on oil.

They do this by capturing and recycling the warmth still present in water vapour condensation and flue exhaust gases to, for example, increase the temperature of the colder water returning from your radiators.

Condensing boilers are also much better for the environment because they emit fewer greenhouse gases.

Does the Grant Vortex Eco 15/21 heat only protect the environment?

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 largest cities of Britain, gas boilers are responsible for dangerous levels of atmospheric nitrogen dioxide emissions. In total, 14% of the UK’s greenhouse gases are produced by central heating systems.

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.

By law, boilers manufactured and supplied in the UK must achieve a SEDBUK rating of "A" and work at a 92% minimum efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Grant Vortex Eco 15/21 was given an efficiency rating of 92.7% with a SEDBUK rating of "A".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

The ERP (Energy Related Products Directive) applies to all products that consume energy at any time in their lifetime, from manufacture to disposal and all points in between.

The intention of this European legislation is to encourage manufacturers to offer end users products that are better for the environment through the creation of fewer harmful gas emissions at all points of a product's life cycle.

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

Am I covered if the Grant Vortex Eco 15/21 heat only boiler breaks down?

The Grant Vortex Eco 15/21 boiler is provided with a parts and labour warranty lasting 2 years.

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

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

The Grant Vortex Eco 15/21 is worthy of consideration if you're looking for a heat only boiler for your flat or house.

Heat only boilers are also referred to as regular boilers, conventional boilers or standard boilers. Heat only boilers require both a hot water/immersion cylinder (usually stored in a landing cupboard or airing cupboard) and a cold water tank (usually stored in a loft) to work. Water passes from the cold tank to the immersion cylinder and the immersion cylinder heats and keeps water warm.

You program your immersion cylinder via the control panel to make sure that you have the hot water and central heating you need. However, if you forget to set your system and there's no water left in the immersion cylinder, it can take up to an hour before you'll have hot water again.

If your home has more than one bathroom or you have a large family and there's a high demand for hot water, a heat only boiler is often a more suitable option than a combi boiler. Although combis offer space-saving advantages, there is a maximum volume of water they can heat at any given time. This means that, if two or more people in your household want hot water at the same time, there will likely be a drop in temperature, volume and pressure to both points.

Is a Grant Vortex Eco 15/21 heat only boiler right for my house or apartment?

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?

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.


How large is the Grant Vortex Eco 15/21?

The Grant Vortex Eco 15/21 is 908 mm in height, 505 mm in width and 800 mm in depth.

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?

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 good for the environment?

With environmental issues in the spotlight, more and more homeowners are becoming concerned about how they heat their homes and how much they're contributing towards combatting climate change.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British 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.

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 (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 15/21 has an ERP rating of "A".

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

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