Grant Vortex Eco 16-21kW heat only Oil boiler frequently asked questions

Is the Grant Vortex Eco 16-21kW a system, regular or combi boiler?

Grant’s Vortex Eco 16-21kW is one you might consider if you’re looking for a heat only boiler for your house or flat.

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 a Grant Vortex Eco 16-21kW 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 a boiler, however, size does not mean how big the boiler is, it means how much power it has.

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Grant Vortex Eco 16-21kW heat only's output at 21 kW, which types of property would this Grant Vortex Eco 16-21kW heat only boiler be most appropriate for?

Most heating engineers would recommend this Grant Vortex Eco 16-21kW heat only boiler as a suitable option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What is the size of the Grant Vortex Eco 16-21kW?

The dimensions of the Grant Vortex Eco 16-21kW are 840 mm [H] x 580 mm [W] x 322 mm [D].

Is the Grant Vortex Eco 16-21kW a condensing or non-condensing boiler?

Condensing boilers like the Grant Vortex Eco 16-21kW 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 Grant Vortex Eco 16-21kW heat only a good choice for 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.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Would choosing the Grant Vortex Eco 16-21kW heat only be an environmentally-friendly choice? If so, let's look at its performance figures.

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Grant Vortex Eco 16-21kW is rated as 90.1% energy efficient, equivalent to a "A" SEDBUK rating.

The Energy Related Products Directive grades products according to the energy they consume and the harmful gas emissions they create, from manufacturing right through to final disposal, including how they're used by customers between these two points.

The Grant Vortex Eco 16-21kW is rated "A".

What is the warranty period for the Grant Vortex Eco 16-21kW?

The Grant Vortex Eco 16-21kW boiler has a warranty covering parts and labour costs for up to 2 years after installation.

Grant Vortex Eco 16-21kW heat only Oil boiler frequently asked questions

Is the Grant Vortex Eco 16-21kW boiler a combi, regular or a system boiler?

The Grant Vortex Eco 16-21kW is worthy of consideration if you're looking for a heat only boiler for your flat or house.

Heat only boilers (often referred to as conventional boilers, standard boilers or regular boilers) consist of a large cold water tank, hot water cylinder with an immersion heater, and a control panel. The cold water tank is often situated in a loft or attic while the hot water cylinder tends to be located in an airing or landing cupboard.

The major advantage of a heat only boiler compared to the more contemporary combi boiler is that it’s possible to run more than one appliance requiring hot water at the same time. With a combi boiler, switching two hot water taps on at the same time will lead to a drop in water pressure, temperature and volume to both points.

Best suited for larger homes, you can program hot water and central heating for times and days that suit you and your family. However, if you forget to set the timer and your hot water cylinder is empty, then you may have to wait up to an hour before you run a bath.

Should I choose a Grant Vortex Eco 16-21kW heat only boiler for my house or flat?

Whether this Grant Vortex Eco 16-21kW 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 Eco 16-21kW heat only is 21 kW, so which types of property would this model be appropriate for?

An experienced PlumbProud heating engineer would recommend that the most suitable type of property for a Grant Vortex Eco 16-21kW heat only would be medium-sized homes and larger apartments containing 10-15 radiators and providing hot water for two bathrooms.


What are the proportions of a Grant Vortex Eco 16-21kW boiler?

The Grant Vortex Eco 16-21kW occupies a space of 840 mm high by 580 mm wide and 322 mm deep.

Is the Grant Vortex Eco 16-21kW condensing or non-condensing?

The Grant Vortex Eco 16-21kW 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 Eco 16-21kW heat only boiler environmentally friendly?

As more of us become concerned by the effects of climate change, the damage we do to the environment by heating our homes has emerged as an important issue for many homeowners.

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.

If you decide to install a Grant Vortex Eco 16-21kW heat only in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Grant Vortex Eco 16-21kW was awarded an efficiency rating of 90.1% with a SEDBUK grading of "A".

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 16-21kW is "A".

If the Grant Vortex Eco 16-21kW heat only boiler breaks down, am I covered?

Grant offers a parts and labour warranty of 2 years on the Grant Vortex Eco 16-21kW.
