Grant Vortex Pro 36/46 heat only Oil boiler frequently asked questions

Grant Vortex Pro 36/46 - combi, system or regular boiler?

The Grant Vortex Pro 36/46 boiler could be suitable for your house or flat if you are looking for a new heat only boiler.

Heat only boilers (sometimes called conventional boilers, standard boilers or regular boilers) require both a hot water/immersion cylinder (normally in a landing cupboard or utility room) and a cold water tank (normally in the attic). The immersion cylinder keeps hot water warm and the cold water tank holds water which it transfers to the immersion cylinder when required.

You set the times that you need heat and hot water with a standard boiler. Once the water in the cylinder is heated, it can be used throughout the day. However, it takes a while for the water to heat up and so, if you haven't set your system, you will have to wait a while for heat and hot water to come back (normally no more than an hour).

Combi boilers deliver hot water instantly but there is a limit to the amount of water they can heat and distribute at any one time. Heat only boilers are usually better choices if you have a large family or more than one bathroom where more than one person in your household requires hot water at the same time.

Is a Grant Vortex Pro 36/46 heat only boiler appropriate 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 36/46 heat only's output at 46 kW, which types of property would this Grant Vortex Pro 36/46 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 36/46 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.


How large is the Grant Vortex Pro 36/46?

The Grant Vortex Pro 36/46 is 908 mm tall, 505 mm wide, and 800 mm deep in size.

External, floor-standing heat only boilers like the Grant Vortex Pro 36/46 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.

Grant Vortex Pro 36/46 – condensing or non-condensing?

Condensing boilers like the Grant Vortex Pro 36/46 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.

Is the heat only Grant Vortex Pro 36/46 boiler energy efficient?

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.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Will choosing to install a Grant Vortex Pro 36/46 heat only in your home help the environment? Let's review the figures.

The energy efficiency rating of the Grant Vortex Pro 36/46 is 90% with a SEDBUK band rating of "A".

Energy efficiency tests record how much energy is wasted on non-core functions during an operation.

By law, all boilers manufactured and supplied in the UK must have a minimum energy efficiency performance level of 92% (equivalent to a SEDBUK "A" grade). Up to April 2018, the minimum performance level was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90%+ an "A" grade).

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 36/46 has an ERP Heat rating of "A".

What length of warranty does the Grant Vortex Pro 36/46 come with?

The manufacturer offers a parts and labour warranty of 2 years on the Grant Vortex Pro 36/46 boiler to new customers.

Grant Vortex Pro 36/46 heat only Oil boiler frequently asked questions

What kind of boiler is the Grant Vortex Pro 36/46 - standard, combi or system?

The Grant Vortex Pro 36/46 is worthy of consideration if you're looking for a heat only boiler for your flat or house.

If your home has more than one bathroom or you have a large family which uses a lot of hot water, a heat only boiler (sometimes called a regular boiler, a conventional boiler or a standard 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 temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you wish 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 and not choose 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.

Is the Grant Vortex Pro 36/46 heat only boiler suitable for my house or apartment?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

The output of a boiler is measured in kilowatts and tells you how much power it has available to heat the water it sends to your hot taps, showers and radiators. The greater the demand for hot water in your home, the larger the output you will need.

It is important to select a boiler with the optimal output rate. Choose one with too high an output and your oil bills will be too expensive. Choose one with too low an output and sometimes the water in your radiators and coming out of your taps will be barely lukewarm.

The output of the Grant Vortex Pro 36/46 heat only is 46 kW kilowatts, so which types of property would this be most suitable for?

Most Gas Safe engineers would suggest that the Grant Vortex Pro 36/46 heat only boiler would be a suitable choice for installation in larger properties including detached homes with 15 or more radiators and two or more bathrooms.


The size of the Grant Vortex Pro 36/46

The Grant Vortex Pro 36/46 is 908 mm in height, 505 mm in width and 800 mm in depth.

External floor-standing heat only boilers like the Grant Vortex Pro 36/46 offer homeowners more indoor space and, unlike their indoor counterparts, they don't create internal noise pollution.

They also provide service engineers with much easier access and are supplied with a sturdy waterproof casing to protect the boiler from rusting and water ingress.

An external boiler like the Grant Vortex Pro 36/46 carries a much-reduced risk of any carbon monoxide entering your home and, because the oil is stored outdoors, there is little to no risk of internal oil leakage damaging the inside of the house and the unpleasant odours that oil leaks cause.

Is the Grant Vortex Pro 36/46 a non-condensing or condensing boiler?

The Grant Vortex Pro 36/46 is a condensing boiler – we recommend to all clients that they choose the very latest condensing boilers because their efficiency continues to improve year after year.

Condensing boilers recycle heat from both water vapour condensation and flue exhaust gases via a secondary heat exchanger. With this heat, it performs other tasks like warming up colder water returning from your radiator without having to use more oil.

You will save money on your oil bills every year by choosing a condensing boiler as well as benefitting the environment.

How energy efficient is the Grant Vortex Pro 36/46 heat only?

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

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Would installing the Grant Vortex Pro 36/46 heat only in your home be an environmentally friendly decision? Let's look closely at the figures.

All boilers manufactured and installed in the UK are required by law to have an energy efficiency rating of at least 92%, equivalent to a good “A” rating on the SEDBUK scale. Before this, the minimum was 88% (ratings of 88% and 89% are equivalent to a high “B” SEDBUK rating and anything 90% or higher is an "A" rating).

A boiler's energy efficiency rating is designed to let you know how much energy is used and wasted during normal functioning.

The Grant Vortex Pro 36/46 was given an efficiency rating of 90% and a band rating of "A".

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 Pro 36/46, the ERP rating is "A".

What is the length of the warranty on the Grant Vortex Pro 36/46?

The parts and labour warranty on the Grant Vortex Pro 36/46 lasts for 2 years.
