What type of boiler is the Grant VortexBlue 26kW?

The Grant VortexBlue 26kW is a heat only boiler you may wish to consider if you want this particular type of boiler for your house or flat.

Heat only boilers (often referred to as standard boilers, regular boilers or conventional boilers) need both a hot water cylinder and a cold water tank to work. The hot water cylinder heats and keeps warm the water you need and is normally installed in either a utility room or attic. The cold water tank holds water which it passes to the hot water cylinder depending on how you've programmed your boiler.

When you program a heat only boiler, you set the times and days when you want central heating and hot water to be available. However, if you don't remember to program your boiler and there's no water left in the hot water cylinder, you may have to wait up to an hour for hot water to come out of your taps.

Heat only boilers can cope with the demand for hot water from multiple taps and sources around your home simultaneously. That's why they're better for larger homes than combi boilers - combi boilers struggle when more than one hot tap is turned on. This is because they have a maximum capacity of water they can heat and distribute at any one time, meaning water pressure, temperature and volume to each tap drops.

Is the Grant VortexBlue 26kW 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.

Your boiler's output indicates the maximum amount of power available to it to heat the water you need to warm your radiators or when you want hot water from your taps. A higher output rate means that your boiler is capable of heating greater volumes of water.

If a boiler's output rate is too low, you'll often find that the water is not as hot as you want it to be. Too high, however, and you'll end up paying more for your oil than you should be.

The Grant VortexBlue 26kW heat only boiler has an output rate of 26 kW, so which types of property would this be suitable for?

A PlumbProud heating engineer would recommend that this Grant VortexBlue 26kW heat only boiler be installed in larger properties including detached homes with 15 or more radiators and two or more bathrooms.

How large is a Grant VortexBlue 26kW boiler?

The Grant VortexBlue 26kW is 908 mm [H] by 505 mm [W] by 1,005 mm [D] in size.

There are several benefits to choosing an external, floor-standing heat only boiler like the Grant VortexBlue 26kW. External boilers free up space indoors and reduce internal noise pollution to almost zero. They are also easier for an engineer to access if a problem develops and an external boiler reduces the chances of carbon monoxide leaking into your property.

External boilers are fitted in weatherproof housing and are perfect for homes that require oil-fired heating because they are not connected to mains gas. Leakage is always a possibility with oil boilers but, as this Grant VortexBlue 26kW heat only boiler is fitted outside your home, there is likely to be much less damage to your property if it leaks and no odour of oil in your home.

Is the Grant VortexBlue 26kW non-condensing or condensing?

The Grant VortexBlue 26kW is a condensing oil boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your oil bills.

Is the Grant VortexBlue 26kW heat only boiler good for the environment?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British homeowners.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Would choosing the Grant VortexBlue 26kW heat only help the environment? Let's see what the statistics suggest.

All boilers manufactured in the UK from April 2018 must operate at a minimum level of energy efficiency of 92% ("A" rating on the SEDBUK scale). Before that, the minimum was 88% - boilers scoring 88/89% were given a SEDBUK "B" rating and 90% or above an "A" rating.

The energy efficiency score of a boiler indicates how much energy it uses and how much goes to waste when in use.

After its assessment, the Grant VortexBlue 26kW was given an efficiency rating of 91.7% and a SEDBUK grading 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 VortexBlue 26kW has an ERP Heat rating of "A".

What warranty does the Grant VortexBlue 26kW heat only boiler come with?

The parts and labour warranty on the Grant VortexBlue 26kW lasts for 2 years.
