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

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

You might want to consider the Grant Vortex Pro 15/26 for your house or flat if you are looking for a heat only boiler.

Sometimes called regular boilers, conventional boilers or standard boilers, heat only boilers require a cold water tank (often kept in the loft) and a hot water cylinder and an immersion heater (often kept in a landing or airing cupboard) to work. The immersion heater heats the water and keeps it warm.

With a heat only boiler, you pre-set a timer to tell the system when you want it to provide you with hot water and central heating. Remember though, if you don't program it and there's no water left in the hot water cylinder, you'll have to wait up to an hour before running a bath or shower.

Heat only boilers are better for larger homes or homes with more than one bathroom where there is a high demand for hot water at certain times of the day. Unlike with combi boilers where water pressure, volume and temperature drops if, for example, more than one person is using a hot tap, regular boilers can cope with multiple members of your household wanting hot water at the same time.

Is the Grant Vortex Pro 15/26 heat only suitable for 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 what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.

A boiler whose output is too high will give you hot water and warm radiators but also higher oil bills, whereas a boiler whose output is too low will result in cheaper oil bills but the water might not always be as hot as you want it to be.

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

Most Gas Safe boiler installers would recommend that a boiler with this output level would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


How large is a Grant Vortex Pro 15/26 boiler?

Grant’s Vortex Pro 15/26 is 908 mm tall, 505 mm wide, and 800 mm deep.

External, floor-standing heat only boilers like the Grant Vortex Pro 15/26 feature weatherproof housing - this means they can be installed outdoors to free up valuable space in your home. An external boiler also minimises indoor noise pollution and reduces the risk of carbon monoxide leaching into your property.

Oil boilers can and do leak. However, when a boiler is fitted externally, any leakage is less likely to damage your property and won't leave an unpleasant odour that is hard to remove. It is also worth remembering that an external boiler will be easier for an engineer to access if a problem develops.

Vortex Pro 15/26 – condensing or non-condensing?

Condensing oil boilers like the Grant Vortex Pro 15/26 are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less oil to run.

How environmentally friendly is the Grant Vortex Pro 15/26 heat only?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

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.

Will installing a Grant Vortex Pro 15/26 heat only in your home be a positive contribution to the environment? The figures below will tell you more.

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 Pro 15/26 was given an efficiency rating of 91.2% 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.

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 Pro 15/26 scores "A".

What length of warranty does the Grant Vortex Pro 15/26 come with?

You receive a parts and labour warranty of 2 years with the Grant Vortex Pro 15/26 boiler.

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

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

If you want a heat only boiler for your flat or house, the Grant Vortex Pro 15/26 might be an option for you to consider.

Heat only boilers (often called regular boilers, conventional boilers or standard boilers) keep hot water warm in an immersion cylinder (generally installed in a utility room or landing cupboard) and also include a cold storage tank that holds water for heating later.

As with all boilers, you set the times and days you want your hot water and central heating to be on. However, if you forget to program the boiler and there's no water left in the immersion cylinder, you may have to wait up to an hour for hot water to return.

A heat only boiler is best for homes with more than one bathroom or a larger family - immersion cylinders store a lot of water and they can deliver water at the same temperature, volume and pressure to multiple points in your home at the same time. This is in contrast to the more popular combi boilers that draw water from the mains and heat it on demand - these types of boiler have volume capacity issues.

Is the Grant Vortex Pro 15/26 heat only boiler suitable for my house or apartment?

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 Pro 15/26 heat only's output at 26 kW, which types of property would this Grant Vortex Pro 15/26 heat only boiler be most appropriate for?

An experienced PlumbProud Gas Safe engineer would recommend that the level of output from this Grant Vortex Pro 15/26 heat only boiler would make it a suitable installation option 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 boiler is 908 mm high, 505 mm wide, and 800 mm deep.

Floor-standing external heat only boilers like the Grant Vortex Pro 15/26 are housed in a sturdy weatherproof casing to protect them from the elements, water ingress, and the risk of rust. Heating engineers also find external boilers much easier to access on repair and maintenance visits.

As the boiler is outdoors, there is less risk of an oil leakage into your home that can cause significant damage and leave your property with an unpleasant, hard-to-remove odour. In addition, there is far less danger to you and your family from carbon monoxide leakage as, in the event of a fault, the gas will disperse in the outside atmosphere.

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

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

Condensing boilers reduce homeowners' oil bills and are better for the environment. They do this by capturing and recycling the heat still present in the flue exhaust gases and water vapour condensation produced when boilers burn oil to generate the power they need to operate.

Is the Grant Vortex Pro 15/26 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.

In the UK, central heating is responsible for 14% of greenhouse gas production. Domestic gas boilers emit large quantities of nitrogen dioxide in British cities.

Would choosing the Grant Vortex Pro 15/26 heat only be an environmentally-friendly choice? If so, let's look at its performance figures.

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 Pro 15/26 was given an efficiency rating of 91.2% 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 Energy Related Products Directive (ERP) is European legislation that applies to all products which use or consume energy during their lifespan - this includes during the manufacturing process and when they're in use, right through to the point of final disposal.

The aim is to encourage manufacturers to create new products that are kinder to the environment and which create fewer harmful gas emissions.

The Grant Vortex Pro 15/26 has an ERP Heat rating of "A".

Am I covered if my Grant Vortex Pro 15/26 heat only boiler breaks down?

The manufacturer offers a parts and labour warranty of 2 years on the Grant Vortex Pro 15/26 boiler to new customers.
