Alpha EVOKE 28 Combi Gas boiler frequently asked questions

Alpha EVOKE 28 - a combi boiler, system boiler or regular boiler?

If you are searching for a combi boiler for your house or flat, the Alpha EVOKE 28 is certainly one to consider.

Traditional boilers would require you to install one or more storage tanks in your property. These tanks either kept the water warm or stored it for later heating. Manufacturers initially designed and introduced combi boilers to the market to offer homeowners the highest levels of warmth and unlimited hot water without taking up as much space.

Combi boilers provide hot water on demand for your radiators and taps. They take water directly from the mains, heat it immediately as it's needed, and then distribute the hot water around your home.

Combi boilers, however, are limited in terms of how much water they can heat at any given time. For example, if one person wishes to take a shower while another wants to turn on a hot water tap, the amount of water reaching each point drops. This results in a drop in the water pressure as well as the temperature.

Is a Alpha EVOKE 28 combi the right boiler for my house or flat?

Whether this Alpha EVOKE 28 Combi 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 gas than you need to.

The output of the Alpha EVOKE 28 combi boiler is 26 kW, so which types of property would this be appropriate for?

A Gas Safe engineer would recommend that the Alpha EVOKE 28 combi boiler is a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.

Flow rates are important when choosing a combi boiler as well as output rates.

A combi boiler's flow rate (measured in litres per minute) describes how much water it can instantly heat then distribute to the taps and radiators in your home - you will need to factor this into your decision on a new combi boiler. This Alpha EVOKE 28 Combi boiler's flow rate is 12 L/m.

If you have a lot of radiators and bathrooms in your home and there's lots of demand within your household for hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate.

However, it's not quite that simple. If your local mains water pressure is low, you're not going to gain any benefit from choosing a combi boiler with a high flow rate because that higher flow rate doesn't mean it can draw more water from the mains pipes.
When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


The size of the Alpha EVOKE 28

The dimensions of the Alpha EVOKE 28 are TBC mm tall, TBC mm wide, and TBC mm deep.

Is the Alpha EVOKE 28 non-condensing or condensing?

We recommend that you choose a condensing boiler wherever possible like the Alpha EVOKE 28 - try to go for the latest model, if possible, to take advantage of improving technology.

Condensing boilers capture and recycle the warmth still present in the water vapour condensation and in flue exhaust emissions created by burning gas to make them more efficient and economical to run.

You will save money on your gas bills too, plus condensing boilers are friendlier to the environment.

How energy efficient is the Alpha EVOKE 28 combi?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

Do the available figures suggest that installing the Alpha EVOKE 28 combi in your property would be an environmentally friendly choice?

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

The Alpha EVOKE 28 was awarded an efficiency rating of 93% with a SEDBUK band rating of "A".

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 is to encourage manufacturers to create products that are more environmentally friendly and which reduce the harmful gas emissions associated with those products.

The ERP gradings for the Alpha EVOKE 28 are "A" for heat and "A" for hot water.

What is the warranty period for the Alpha EVOKE 28?

The Alpha EVOKE 28 boiler is provided with a parts and labour warranty lasting 7 years.

Alpha EVOKE 28 Combi Gas boiler frequently asked questions

Is the Alpha EVOKE 28 a combi boiler, system boiler or regular boiler?

The Alpha EVOKE 28 is worthy of consideration if you're looking for a combi boiler for your flat or house.

A combi boiler could be a better choice than a standard boiler if space is at a premium in your home. Combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a hot water cylinder and a cold water tank.

Water is heated on demand and then distributed directly to your taps and showers. This means that combi boilers use less fuel and so reduce your gas bills.

The main disadvantage to combi boilers is that they can only heat a limited volume of water at any given time. If more than one tap or shower is in use, the hot water supply to both could be restricted and both the water pressure and temperature will drop.

Would the Alpha EVOKE 28 combi be a suitable choice of boiler 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".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.

The Alpha EVOKE 28 combi boiler has an output of 26 kW, so which types of property would it be most appropriate for?

Most heating engineers would suggest that the Alpha EVOKE 28 combi boiler would be a suitable choice for installation in smaller homes and apartments with up to 10 radiators and one bathroom.

With combi boilers, flow rates are as important a consideration as output rates.

All combi boilers draw water from the mains. They then heat this water instantly whenever it's needed and distribute it to your radiators and taps.

A boiler's "flow rate" describes how much water a boiler can draw from the mains at any one time, which it then heats and sends around your home (measured in litres per minute). This Alpha EVOKE 28 Combi boiler's flow rate is 12 L/m.

If your home has a large number of radiators, a lot of bathrooms, or multiple people who wish to use the hot water at the same time, your combi boiler may not be able to draw as much water from the mains as it needs to serve everyone, regardless of how high the flow rate is.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


Alpha EVOKE 28 - size in millimetres

The Alpha EVOKE 28 boiler measures TBC mm [H] x TBC mm [W] x TBC mm [D] in size.

Is the Alpha EVOKE 28 non-condensing or condensing?

We recommend that you select a condensing boiler like the Alpha EVOKE gas Alpha EVOKE 28 for your home if possible because of the environmental benefits and the money you'll save on your gas bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning gas for reuse.

How energy efficient is the Alpha EVOKE 28 combi?

Price and performance are two important issues when choosing a boiler but now, for many people in the UK, so is the environmental impact of how we heat our homes and its effect on climate change.

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

Do the figures suggest that installing the Alpha EVOKE 28 combi at your property would help in the fight against climate change?

All boilers manufactured in the UK from April 2018 must achieve a SEDBUK “A” grade and an energy efficiency rating of 92% or above. Before that, the minimum was 88% - efficiency ratings of 88% and 89% were scored a “B” and 90%+ an "A".

A boiler's energy efficiency rating describes how much energy it uses and wastes during its standard operation.

The energy efficiency of the Alpha EVOKE 28 was rated at 93% with a SEDBUK grading 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 Alpha EVOKE 28 has a rating of "A" for heat and "A" for water.

Will I be covered if the Alpha EVOKE 28 combi breaks down?

The parts and labour warranty on the Alpha EVOKE 28 covers all repair-related costs for 7 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.
