Grant Vortex Pro 15/26 heat only Oil boiler frequently asked questions

Grant Vortex Pro 15/26 - a system boiler, regular boiler or combi boiler?

If you are searching for a heat only boiler for your house or flat, the Grant Vortex Pro 15/26 is certainly one to consider.

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 Pro 15/26 heat only the right boiler for my house or flat?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your oil bills will go up and not down.

The output of the Grant Vortex Pro 15/26 heat only is 26 kW, so which types of property would this Grant Vortex Pro 15/26 heat only boiler be an appropriate choice for?

An experienced Gas Safe boiler installer would be likely to recommend that this Grant Vortex Pro 15/26 heat only boiler is capable of providing heating and hot water to 15 or more radiators and two or more bathrooms and would therefore be most suitable for larger properties including detached homes.


What size is the Grant Vortex Pro 15/26 boiler?

The Grant Vortex Pro 15/26 is 908 mm [H] by 505 mm [W] by 800 mm [D] in size.

External, floor-standing heat only boilers like the Grant Vortex Pro 15/26 don't require you to find space in your home for them and, because they're outside, you'll never hear them working unless you're out in the garden.

They provide much easier access for a heating engineer in case of a fault and their sturdy waterproof covering can handle the British climate as well as prevent rusting and water ingress.

Other benefits include the fact that gas will disperse into the atmosphere outdoors in the event of a carbon monoxide leak. The chances of an oil leak damaging your property are also greatly reduced because the boiler is not installed inside your property.

Is the Grant Vortex Pro 15/26 a condensing or non-condensing boiler?

The Grant Vortex Pro 15/26 is a condensing oil boiler - we strongly recommend that you choose one of the latest condensing models if possible.

With a condensing boiler, you save money on your oil bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

Is the Grant Vortex Pro 15/26 heat only an environmentally friendly boiler?

How we heat our homes and the damage this does to the environment has become a pressing concern for many homeowners worried about the effects and impact of climate change.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Do the figures suggest that installing the Grant Vortex Pro 15/26 heat only at your property would help in the fight against climate change?

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The Grant Vortex Pro 15/26 was awarded an efficiency rating of 91.2% and a band rating of "A".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

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 Pro 15/26 has been given an ERP rating of "A".

If the Grant Vortex Pro 15/26 heat only boiler breaks down, am I covered?

The parts and labour warranty on the Grant Vortex Pro 15/26 covers all repair-related costs for 2 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.

Grant Vortex Pro 15/26 heat only Oil boiler frequently asked questions

Is the Grant Vortex Pro 15/26 a combi, system or regular boiler?

The Grant Vortex Pro 15/26 may be worth considering if you are looking for a heat only boiler for your house or flat.

Heat only boilers (often referred to as standard boilers, regular boilers or conventional boilers) need both a hot water cylinder and a cold water tank to work. The hot water cylinder heats and keeps warm the water you need and is normally installed in either a utility room or attic. The cold water tank holds water which it passes to the hot water cylinder depending on how you've programmed your boiler.

When you program a heat only boiler, you set the times and days when you want central heating and hot water to be available. However, if you don't remember to program your boiler and there's no water left in the hot water cylinder, you may have to wait up to an hour for hot water to come out of your taps.

Heat only boilers can cope with the demand for hot water from multiple taps and sources around your home simultaneously. That's why they're better for larger homes than combi boilers - combi boilers struggle when more than one hot tap is turned on. This is because they have a maximum capacity of water they can heat and distribute at any one time, meaning water pressure, temperature and volume to each tap drops.

Should I install a Grant Vortex Pro 15/26 heat only boiler in my house or flat?

Whether this Grant Vortex Pro 15/26 heat only boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions, however - it means how powerful it is.

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher oil bills than you need to for years to come.

The output of the Grant Vortex Pro 15/26 heat only is 26 kW, so which types of property is this Grant Vortex Pro 15/26 heat only boiler appropriate for?

A Gas Safe boiler installer would recommend that this Grant Vortex Pro 15/26 heat only boiler would be a suitable choice for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What size is the Grant Vortex Pro 15/26 boiler?

The Grant Vortex Pro 15/26 measures 908 mm in height and has a width of 505 mm and a depth of 800 mm.

External, floor-standing heat only boilers like the Grant Vortex Pro 15/26 are installed outdoors saving you valuable space inside your home as well as protecting you from the noise made by a oil boiler during its operation.

Supplied in sturdy, weatherproof housing that protects it from rusting and water ingress, external boilers are much easier for heating engineers to gain access to in case of repair or on maintenance visits.

Because the boiler is not inside your property, carbon monoxide fumes escape into the atmosphere if there is a leak. In addition, there's little to no chance of oil getting into your home if the boiler malfunctions - oil spills inside your property can cause significant damage and leave unpleasant odours that can be very hard to shift.

Is the Grant Vortex Pro 15/26 condensing or non-condensing?

We recommend that, if possible, you choose a condensing boiler like the Grant Vortex Pro 15/26.

Condensing boilers are more energy-efficient. They achieve this efficiency by capturing the heat present in flue exhaust gases and water vapour condensation and recycling that heat to, for example, warm colder water coming back from your radiators.

By choosing the latest condensing boiler, you'll also notice a significant reduction in your oil bills, particularly if you're replacing a boiler more than 15 years old.

How does the Grant Vortex Pro 15/26 heat only rate environmentally?

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.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Will choosing to install a Grant Vortex Pro 15/26 heat only in your home help the environment? Let's review the figures.

The energy efficiency rating for a boiler describes the amount of energy it uses and wastes during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "B" SEDBUK rating, 90%+ = "A" SEDBUK rating).

The Grant Vortex Pro 15/26 scored an efficiency rating of 91.2% and a SEDBUK band rating of A.

The ERP, short for the Energy Related Products Directive, is a European directive aimed at encouraging manufacturers to create products that are environmentally friendlier at all stages, including during manufacturing, when the product is in active use, and right through to the point of final disposal.

The Grant Vortex Pro 15/26 has a rating of "A" .

What warranty does the Grant Vortex Pro 15/26 heat only boiler come with?

The Grant Vortex Pro 15/26 boiler comes with a parts and labour warranty of 2 years.
