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

You may wish to consider installing the Grant Vortex Pro 36/46 if you are looking for a heat only boiler for your house or flat.

Sometimes called regular boilers, conventional boilers or standard boilers, heat only boilers require a cold water tank (often kept in the loft) and a hot water cylinder and an immersion heater (often kept in a landing or airing cupboard) to work. The immersion heater heats the water and keeps it warm.

With a heat only boiler, you pre-set a timer to tell the system when you want it to provide you with hot water and central heating. Remember though, if you don't program it and there's no water left in the hot water cylinder, you'll have to wait up to an hour before running a bath or shower.

Heat only boilers are better for larger homes or homes with more than one bathroom where there is a high demand for hot water at certain times of the day. Unlike with combi boilers where water pressure, volume and temperature drops if, for example, more than one person is using a hot tap, regular boilers can cope with multiple members of your household wanting hot water at the same time.

Is the Grant Vortex Pro 36/46 heat only boiler from the Vortex Pro range a suitable choice 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.

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

The Grant Vortex Pro 36/46 heat only's output is 46 kW, so which types of property would this Grant Vortex Pro 36/46 heat only boiler be appropriate for?

An experienced Gas Safe boiler installer would be likely to recommend that this Grant Vortex Pro 36/46 heat only boiler is capable of providing heating and hot water to 15 or more radiators and two or more bathrooms and would therefore be most suitable for larger properties including detached homes.

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

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

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 condensing or non-condensing?

The Grant Vortex Pro 36/46 is a condensing oil boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

Is the Grant Vortex Pro 36/46 heat only a good choice for the environment?

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.

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.

Would installing a Grant Vortex Pro 36/46 heat only boiler in your home be a green choice? Let's look at the numbers.

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 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 warranty do I get if I purchase the Grant Vortex Pro 36/46 boiler?

On the Grant Vortex Pro 36/46, the manufacturer offers a parts and labour warranty of 2 years.
