Grant Vortex Eco 15/21 heat only Oil boiler frequently asked questions

Grant Vortex Eco 15/21 - a regular boiler, combi boiler or system boiler?

The Grant Vortex Eco 15/21 is a oil heat only boiler.

Heat only boilers (sometimes called conventional boilers, standard boilers or regular boilers) need both a hot water cylinder with an immersion heater and a cold-water tank to work. The cold water tank (normally found in an attic or a loft) passes water when required to the hot water cylinder (normally found in a landing or airing cupboard), which heats the water and keeps it warm.

When you set the times you want for your hot water and central heating, the hot water for your taps, showers, baths and radiators is drawn from the hot water cylinder. Bear in mind though that, if you forget to program the system and the hot water cylinder is empty, you may have to wait up to an hour for your hot water.

A heat only boiler is usually the recommended option for families or properties with multiple bathrooms. This is because, unlike combi boilers which can only effectively provide for one outlet at a time without a drop in water pressure, volume or temperature, standard boilers can handle demand from multiple points around the home at once.

Is the Grant Vortex Eco 15/21 heat only boiler a suitable option 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 Eco 15/21 heat only is 21 kW, so which types of property would this Grant Vortex Eco 15/21 heat only boiler be an appropriate choice for?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Grant Vortex Eco 15/21 heat only boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


How big is the Grant Vortex Eco 15/21?

The Grant Vortex Eco 15/21 occupies a space of 860 mm high by 430 mm wide and 605 mm deep.

Because of their convenient and compact size, wall-hung boilers have become the popular choice for homeowners over the last 20 years. Yet while hundreds of thousands of UK properties still use floor-standing boilers like the Grant Vortex Eco 15/21, many consider switching to wall-mounted units to create extra living space.

We can replace your floor-standing boiler if you wish but there may be an additional cost if we have to replace much of your existing pipework. The savings you make on your oil bills every quarter should repay that investment within a few years.

Vortex Eco 15/21 – non-condensing or condensing?

This Grant Vortex Eco 15/21 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.

Is the Grant Vortex Eco 15/21 heat only considered environmentally friendly?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

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

Let's take a closer look at whether installing a Grant Vortex Eco 15/21 heat only would be a good choice for the environment.

All boilers manufactured and supplied in the UK are assigned two energy efficiency ratings. By law, they must achieve a SEDBUK "A" rating subject to a minimum efficiency level of 92%. Prior to that, the minimum was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90% and above an "A" grade).

The ratings awarded to the Grant Vortex Eco 15/21 are 92.7% with a SEDBUK rating of "A".

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use right through to final disposal.

The Grant Vortex Eco 15/21 has a rating of "A".

What length of warranty does the Grant Vortex Eco 15/21 come with?

Parts and labour charges incurred for repairs made to your new Grant Vortex Eco 15/21 are covered by a 2 year warranty.

Grant Vortex Eco 15/21 heat only Oil boiler frequently asked questions

Is this Grant Vortex Eco 15/21 boiler a combi, system or regular boiler?

If you’re looking for a heat only boiler for your house or flat, you may wish to the consider the Grant Vortex Eco 15/21.

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.

Is the Grant Vortex Eco 15/21 heat only boiler a suitable option for my house or flat?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Grant Vortex Eco 15/21 heat only boiler is 21 kW kilowatts. Which types of property would this be appropriate for?

A heating engineer would recommend that this Grant Vortex Eco 15/21 heat only boiler would be a suitable installation choice for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


How large is the Grant Vortex Eco 15/21?

The Grant Vortex Eco 15/21's dimensions are 860 mm [H] x 430 mm [W] x 605 mm [D].

Many homes in the UK still have floor-standing boilers like the Grant Vortex Eco 15/21, 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 the Grant Vortex Eco 15/21 condensing or non-condensing?

This Grant Vortex Eco 15/21 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.

Is the Grant Vortex Eco 15/21 heat only a good choice for the environment?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Would choosing a Grant Vortex Eco 15/21 heat only help in the fight against climate change? What do the performance statistics suggest?

Boilers manufactured in the UK must be tested and, by law, achieve an energy efficiency rating of 92% or above, equivalent to a SEDBUK "A" grade. Most boilers achieve an "A" rating meaning they are at least 88% efficient.

The energy efficiency of a boiler indicates the amount of energy it uses (and wastes) during operation.

The Grant Vortex Eco 15/21 has been assigned an efficiency rating of 92.7% with a SEDBUK rating 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 15/21 is "A".
