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

Is this Grant Vortex Pro 36/46 boiler a combi, system or regular boiler?

If you want a heat only boiler for your flat or house, the Grant Vortex Pro 36/46 might be an option for you to consider.

You may hear a heat only boiler described as a standard boiler, a regular boiler, or a conventional boiler but the terms mean the same. Heat only boilers require a hot water cylinder (usually stored in a landing or airing cupboard) and a cold water storage tank (usually stored in the loft) to operate. Your water is kept warm by the hot water cylinder throughout the day.

A heat only boiler lets you schedule the hot water and central heating you want for set times of the day. However, you'll have to wait before having a bath or shower if you forget to set it and there's no hot water left in the tank.

If you have a bigger family or more than one bathroom, a heat only boiler is a better option than a combi boiler in many cases. This is because a combi boiler struggles to maintain water volume, pressure and temperature to multiple points in a home simultaneously.

Would the Grant Vortex Pro 36/46 heat only boiler be suitable for my house or flat?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher oil bills.

Which types of property would this Grant Vortex Pro 36/46 heat only boiler be appropriate for given its output of 46 kW?

A PlumbProud heating engineer would recommend that this Grant Vortex Pro 36/46 heat only boiler be installed in larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What size is the Grant Vortex Pro 36/46 boiler?

The Grant Vortex Pro 36/46 is 900 mm [H] by 470 mm [W] by 603 mm [D] in size.

Many homeowners still have floor-standing boilers like the Grant Vortex Pro 36/46 even though wall-mounted boilers have been the preferred choice because of their compact size. If you want to replace your existing boiler with a compact wall-hung one to free up extra living space for you and your family, we can do this for you but please be aware that we may need to replace much of your existing pipework, which will incur an additional charge.

However, given the efficiency of modern wall-mounted oil boilers, the savings you make on your energy bills over the coming years should more than repay the cost of your investment.

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

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Grant Vortex Pro 36/46 are more efficient with the oil they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns oil to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

Is choosing the Grant Vortex Pro 36/46 heat only boiler environmentally friendly?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

Approximately 14% of the UK's greenhouse gas production is caused by our central heating systems. The gas boilers in larger urban areas of Britain are mainly responsible for emissions of toxic nitrogen dioxide.

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.

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

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

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

The ERP (Energy Related Products Directive) is European legislation that aims to reduce the use of energy at all points during a product's life, from the point of manufacture to when it's in active use right through to final disposal.

The regulation aims to encourage manufacturers to create products that are more environmentally friendly and which reduce gas emissions associated with those products.

The ERP grading for the Grant Vortex Pro 36/46 is "A".

Will I be covered if the Grant Vortex Pro 36/46 heat only breaks down?

A parts and labour warranty of 2 years is included with the Grant Grant Vortex Pro 36/46 boiler.

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

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

If you are searching for a heat only boiler for your house or flat, the Grant Vortex Pro 36/46 is certainly one to consider.

Heat only boilers are also referred to as regular boilers, conventional boilers or standard boilers. Heat only boilers require both a hot water/immersion cylinder (usually stored in a landing cupboard or airing cupboard) and a cold water tank (usually stored in a loft) to work. Water passes from the cold tank to the immersion cylinder and the immersion cylinder heats and keeps water warm.

You program your immersion cylinder via the control panel to make sure that you have the hot water and central heating you need. However, if you forget to set your system and there's no water left in the immersion cylinder, it can take up to an hour before you'll have hot water again.

If your home has more than one bathroom or you have a large family and there's a high demand for hot water, a heat only boiler is often a more suitable option than a combi boiler. Although combis offer space-saving advantages, there is a maximum volume of water they can heat at any given time. This means that, if two or more people in your household want hot water at the same time, there will likely be a drop in temperature, volume and pressure to both points.

Is the Grant Vortex Pro 36/46 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 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 Pro 36/46 heat only boiler is 46 kW kilowatts. Which types of property would this be appropriate for?

An experienced PlumbProud Gas Safe boiler installer would almost certainly recommend that this Grant Vortex Pro 36/46 heat only boiler would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What are the dimensions of the Grant Vortex Pro 36/46 boiler?

The size of the Grant Vortex Pro 36/46 boiler is 900 mm tall, 470 mm wide, and 603 mm deep.

Wall-hung boilers have become the preferred choice for homeowners in the UK over the last 20 years, but hundreds of thousands of homes still use bulkier floor-standing models for their central heating. It is possible to replace your floor-standing boiler with a wall-mounted one if you wish so that you and your family have more living space. But we must advise you that you may also have to pay to replace some or all of your existing pipework.

You should however be able to recoup this cost in full after a few years because of the savings you make each quarter on your oil bills.

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

The Grant Vortex Pro 36/46 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 36/46 heat only boiler rated as environmentally friendly?

How we heat our homes and the damage this does to the environment has become a pressing concern for many homeowners worried about the effects and impact of climate change.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Would choosing a Grant Vortex Pro 36/46 heat only help the environment? Let’s see what the performance figures suggest.

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 36/46 was given an efficiency rating of 90% 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.

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 Pro 36/46 has been given an ERP rating of "A".

How long is the warranty period on a Grant Vortex Pro 36/46 heat only boiler?

A parts and labour warranty of 2 years is included when you purchase the Grant Vortex Pro 36/46 boiler through PlumbProud.
