Grant Vortex Boiler House 15-21kW heat only Oil boiler frequently asked questions

Is the Grant Vortex Boiler House 15-21kW a regular, combi or system boiler?

The Grant Vortex Boiler House 15-21kW is worthy of consideration if you're looking for a heat only boiler for your flat or house.

Heat only boilers, sometimes known as standard boilers, regular boilers or conventional boilers, are better for homes with multiple bathrooms or larger families where members of your household may need to use hot water at the same time as each other, such as a shower in the bathroom and a hot water tap in the kitchen. This is because, unlike combi boilers, they can handle demand from more than one point at a time with no drop in water pressure, temperature and volume.

Heat only boilers use a hot water cylinder with an immersion heater (normally installed in an airing or landing cupboard) and a cold-water tank (normally stored in the loft).

You program a heat only boiler to provide you with the central heating and hot water you need at specific times of the day, such as first thing in the morning. However, if you forget to set timings and there is no water left in the hot water tank, you may have to wait up to an hour before you have hot water again.

Is the Grant Vortex Boiler House 15-21kW heat only boiler the right choice for my house or apartment?

Whether this Grant Vortex Boiler House 15-21kW 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 Boiler House 15-21kW heat only is 21 kW, so which types of property is this Grant Vortex Boiler House 15-21kW heat only boiler appropriate for?

An experienced PlumbProud boiler engineer would recommend that this Grant Vortex Boiler House 15-21kW heat only boiler be installed in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


How large is the Grant Vortex Boiler House 15-21kW?

The size of the Grant Vortex Boiler House 15-21kW boiler is 714 mm tall, 431 mm wide, and 597 mm deep.

Many homes in the UK still have floor-standing boilers like the Grant Vortex Boiler House 15-21kW, even though wall-hung boilers have become the product of choice for most homeowners over the last 20 years. If you'd like to replace your existing floor-standing boiler with a compact, wall-mounted boiler to create more space for you and your family, please bear in mind that your pipework may need to be replaced in addition to the cost of the boiler and its installation.

Savings on your oil bills will eventually completely pay for the one-time investment but it will take a few years.

Is this Grant boiler non-condensing or condensing?

This Grant Vortex Boiler House 15-21kW 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.

What energy efficiency ratings have been awarded to the Grant Vortex Boiler House 15-21kW heat only?

As more of us are increasingly concerned about climate change, how we heat our homes and its impact on the environment has become an issue of importance to homeowners.

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Would installing a Grant Vortex Boiler House 15-21kW heat only boiler in your home be a green choice? Let's look at the numbers.

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 Boiler House 15-21kW is rated as 90.7% energy efficient, equivalent to a "A" SEDBUK rating.

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 Boiler House 15-21kW has been given an ERP rating of "A".

Grant Vortex Boiler House 15-21kW heat only Oil boiler frequently asked questions

Is the Grant Vortex Boiler House 15-21kW a regular, combi or system boiler?

The Grant Vortex Boiler House 15-21kW is a oil heat only boiler.

If your home has more than one bathroom or you have a large family that 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 Boiler House 15-21kW heat only boiler suitable for my house or apartment?

Whether this Grant Vortex Boiler House 15-21kW heat only boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for oil than you need to.

The output of the Grant Vortex Boiler House 15-21kW heat only boiler is 21 kW, so which types of property would this be appropriate for?

An experienced PlumbProud boiler engineer would recommend that this Grant Vortex Boiler House 15-21kW heat only boiler be installed in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


The size of the Grant Vortex Boiler House 15-21kW

The Grant Vortex Boiler House 15-21kW is 714 mm tall, 431 mm wide, and 597 mm deep in size.

Over the last 20 years, compact wall-hung boilers have been installed in far greater numbers in UK properties than floor-standing boilers like the Grant Vortex Boiler House 15-21kW. While hundreds of thousands of properties still have floor-standing boilers, many homeowners consider making the switch to wall-hung boilers to increase the amount of living space that they and their families can enjoy. We can swap your old floor-standing boiler for a wall-mounted boiler but please bear in mind that there may be an additional cost for your installation if we have to replace the pipework.

You should though be able to recoup this investment in full in just a few years with the savings you make on your oil bills.

Is the Grant Vortex Boiler House 15-21kW a condensing or non-condensing boiler?

The Grant Vortex Boiler House 15-21kW is a condensing oil boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when oil is burned to provide your boiler with power.

This means it needs less oil to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

Is the Grant Vortex Boiler House 15-21kW heat only an environmentally friendly boiler?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

If you would like your next boiler to help in the fight against climate change, would the Grant Vortex Boiler House 15-21kW heat only be a suitable choice?

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 Boiler House 15-21kW was given an efficiency rating of 90.7% 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 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 Boiler House 15-21kW, the ERP rating is "A".

How many years' warranty does the Grant Vortex Boiler House 15-21kW heat only come with?

On the Grant Vortex Boiler House 15-21kW, the manufacturer offers a parts and labour warranty of 2 years.
