Grant Vortex Eco 21/26 heat only Oil boiler frequently asked questions

Is the Grant Vortex Eco 21/26 a standard, combi or system boiler?

The Grant Vortex Eco 21/26 is a oil heat only boiler.

Large family homes and properties with more than one bathroom benefit most from installing a heat only boiler (also referred to as a conventional boiler, a standard boiler or a regular boiler). Heat only boilers require both a cold water tank and hot water cylinder and an immersion heater. The immersion heater heats and keeps the water warm and feeds hot water to taps, radiators and other sources via the boiler.

Tell your boiler the times and days when you want hot water and central heating and it'll be there waiting for you. However, if you forget and there's no hot water left in your tank, you'll have to wait up to an hour before it's ready.

The biggest benefit of a heat only boiler is that, unlike a combi boiler, it’s possible to run two taps with hot water at the same time with no drop in pressure, volume or temperature (a known issue with combi boilers). It also means you can shower and have the dishwasher running at the same time without your water pressure being affected.

Is the Grant Vortex Eco 21/26 heat only boiler from the Vortex Eco range 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, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your oil bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Grant Vortex Eco 21/26 heat only's output at 26 kW, which types of property would this Grant Vortex Eco 21/26 heat only boiler be most appropriate for?

An experienced PlumbProud Gas Safe boiler installer would likely recommend that this Grant Vortex Eco 21/26 heat only boiler would be suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


How big is the Grant Vortex Eco 21/26?

The Grant Vortex Eco 21/26 measures 860 mm in height by 430 mm in width by 605 mm in depth.

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 21/26. 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 the Grant Vortex Eco 21/26 condensing or non-condensing?

We strongly recommend that you choose a condensing boiler like the Grant Vortex Eco 21/26 - the technology is improving every year so the newer the boiler, the better.

A condensing boiler captures and recycles the warmth still present in flue exhaust gases and water vapour condensation into heat, allowing it to perform more efficiently on tasks like heating the colder water returning from your radiators.

They also offer significant annual savings on household oil bills as well as being more environmentally friendly.

How energy efficient is the Grant Vortex Eco 21/26 heat only boiler?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

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.

Would installing a Grant Vortex Eco 21/26 heat only boiler in your home be a green choice? Let's look at the numbers.

All new British boilers must perform to a legal minimum energy efficiency of 92% (a low to good SEDBUK "A" rating). Prior to April 2018, the target was 88% (86-90% = SEDBUK "B" and 90%+ = SEDBUK "A").

Efficiency ratings are intended to let consumers know how much energy a boiler uses in its day-to-day activities and how much energy goes to waste.

The Grant Vortex Eco 21/26 was awarded an efficiency rating of 91.7%, equivalent to a SEDBUK grade of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP) with the aim of ensuring that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

This legislation aims to conserve energy at all life cycle stages, from initial production through to actual use by a customer and up to the point of disposal.

The Grant Vortex Eco 21/26 has been given an ERP rating of "A".

Grant Vortex Eco 21/26 heat only Oil boiler frequently asked questions

What type of boiler is the Grant Vortex Eco 21/26?

Grant’s Vortex Eco 21/26 is one you might consider if you’re looking for a heat only boiler for your house or flat.

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 21/26 heat only boiler suitable 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 21/26 heat only is 26 kW kilowatts, so which types of property would this be appropriate for?

A PlumbProud Gas Safe engineer would recommend that this Grant Vortex Eco 21/26 heat only boiler is suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


Grant Vortex Eco 21/26 size

The Grant Vortex Eco 21/26 is 860 mm in height, 430 mm in width and 605 mm in depth.

Over the last 20 years, most homeowners in the UK have shifted from floor-standing boilers like the Grant Vortex Eco 21/26 to more compact, wall-hung units to free up space. You can replace your existing floor-standing boiler with a compact but you should be aware that much of the pipework might need replacing in addition to the cost of the boiler and installation.

There will be a significant one-time investment here - the savings on your oil bills will eventually pay for it but this will take a few years.

Is the Grant Vortex Eco 21/26 a condensing or non-condensing boiler?

This Grant Vortex Eco 21/26 is a condensing oil boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your oil bills as well as benefitting the wider environment.

Is the Grant Vortex Eco 21/26 heat only boiler environmentally friendly?

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

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Is the Grant Vortex Eco 21/26 heat only an environmentally friendly choice for your home? Let’s have a look at 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 21/26 has been given a rating of 91.7% for energy efficiency, equivalent to a SEDBUK "A" rating.

The ERP (or Energy Related Products Directive) is a European regulation governing products which require energy to operate throughout their lives and encourages manufacturers to create products that are more environmentally friendly.

The legislation is designed to reduce the potential for harmful gas emissions during manufacturing and actual use right through to the point of final disposal.

For the Grant Vortex Eco 21/26, the ERP rating is "A".

What is the warranty period on a Grant Vortex Eco 21/26 heat only boiler?

A parts and labour warranty of 2 years is included when you purchase the Grant Vortex Eco 21/26 boiler through PlumbProud.
