Alpha EVOKE 33 Combi Gas boiler frequently asked questions

Alpha EVOKE 33 - a combi boiler, system boiler or regular boiler?

The Alpha EVOKE 33 boiler is a combi boiler you may wish to consider when looking for a new boiler for your house or flat.

Traditionally, boilers needed one or more large tanks installed in your property to store their heated water or water that was to be heated later. These tanks were often too large to be practical for most homes so the combi boiler was introduced to Britain in the 1970s by manufacturers to help homeowners overcome this issue.

Instead of using tanks as storage, a combi boiler heats water on demand. It draws water from the mains and heats it instantly on demand before distributing it to wherever it is needed in a property, be it your taps or radiators.

Unfortunately, combi boilers have one main disadvantage for larger properties or larger households. Because they have a maximum volume of water that can be heated on demand at any given time, water pressure, volume and temperature will drop if, for example, someone is taking a shower and another person in your home wants to use a hot water tap at the same time.

Would the Alpha EVOKE 33 combi be a suitable boiler for my house or flat?

Whether this Alpha EVOKE 33 Combi boiler is right for your property depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your gas bills than you need to.

Which types of property would this Alpha EVOKE 33 Combi boiler be appropriate for given its output of 29 kW?

To most boiler engineers, the Alpha EVOKE 33 combi EVOKE would be most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

You should also consider a combi boiler's "flow rate" when making your choice.

The flow rate indicates how much water it can take from the mains supply at any one time (measured in litres per minute), which it then heats and distributes to different points in your home like your bathroom, kitchen and radiators. This Alpha EVOKE 33 Combi boiler's flow rate is 14 L/m.

Combi boilers have no storage tanks like system or heat only boilers. This means that if the water pressure where you live is low, there's no benefit in spending money on a combi with a high flow rate because a high flow rate doesn't mean it can draw any more water from the mains.

In addition, there might be lots of people in your household who want to use hot water at the same time while also having the central heating on. Given that average mains pressure in the UK is between 10 and 12 litres per second and a power shower usually requires about 12 litres of water per minute, a combi boiler might not be the right choice for you and your family.

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.


Dimensions of the Alpha EVOKE 33 boiler

The Alpha EVOKE 33 is TBC mm in height, TBC mm in width and TBC mm in depth.

Alpha EVOKE 33 – non-condensing or condensing?

Condensing gas boilers like the Alpha EVOKE 33 are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less gas to run.

Is the combi Alpha EVOKE 33 boiler energy efficient?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on 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.

Do the figures suggest that installing the Alpha EVOKE 33 combi at your property would help in the fight against climate change?

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Alpha EVOKE 33 has been given a rating of 93% for energy efficiency, equivalent to a SEDBUK "A" rating.

All products that consume energy throughout their lifespan must comply with the Energy Related Products (ERP) Directive.

Companies are legally obliged to reduce harmful gas emissions at all stages of a product's life cycle, from initial manufacturing right through to final disposal as well as when the product is in actual use.

The Alpha EVOKE 33 scores "A" for heat and "A" for water.

What is the warranty period on a Alpha EVOKE 33 combi boiler?

A parts and labour warranty of 7 years is included when you purchase the Alpha EVOKE 33 boiler through PlumbProud.

Alpha EVOKE 33 Combi Gas boiler frequently asked questions

Alpha EVOKE 33 - a regular, combi or system boiler?

When looking for a combi boiler for your house or flat, the Alpha EVOKE 33 might be a suitable option for you.

Traditionally, most boilers required you to find space in your property for one or more large storage tanks. These tanks would either keep water warm or hold it in reserve for later heating. Manufacturers originally introduced combi boilers to offer homeowners the same level of warmth and hot water without taking up as much space – remember that the UK has some of the smallest homes in the Western world.

With a combi boiler, the hot water needed for your radiators and taps is provided on demand. Water from the mains passes through your combi boiler and the technology within it instantly heats the cold water. It then distributes that hot water around your home.

The biggest drawback for combi boilers is that they have a maximum capacity in volume for heating water. This means that if someone wants to use the shower while another person wants to use a hot water tap, the amount of water reaching each point falls, resulting in a drop in water pressure.

Is a Alpha EVOKE 33 combi boiler suitable for my house or apartment?

Selecting the right boiler for your property means selecting a boiler that is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for gas than is necessary.

The Alpha EVOKE 33 combi boiler has an output level of 29 kW, so which types of property would it be appropriate for?

An experienced heating engineer would recommend that the Alpha EVOKE 33 combi boiler is a suitable choice for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

Please remember to consider "flow rates" as well when choosing your new boiler. All combi boilers including the Alpha EVOKE 33 draw water from the mains.

Each combi boiler has its own flow rate (measured in litres per minute) - this tells you how much water it can heat and distribute to your home’s taps and radiators straight from the mains. This Alpha EVOKE 33 Combi boiler's flow rate is 14 L/m.

There is no benefit to you in choosing a combi with a high flow rate if your mains pressure is low - save money by buying a boiler whose flow rate is equal to or slightly more than the pressure in your water pipes.

In addition, if you have a lot of radiators and bathrooms in your home or you have a large household that often uses lots of hot water at the same time, like for regular morning and evening showers, a combi boiler may not be suitable.

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 dimensions of the Alpha EVOKE 33 are

The Alpha EVOKE 33 boiler measures TBC mm [H] x TBC mm [W] x TBC mm [D] in size.

Alpha EVOKE 33 – condensing or non-condensing?

Condensing boilers like the Alpha EVOKE 33 improve energy efficiency and reduce your annual expenditure on gas.

They do this by capturing and recycling the warmth still present in water vapour condensation and flue exhaust gases to, for example, increase the temperature of the colder water returning from your radiators.

Condensing boilers are also much better for the environment because they emit fewer greenhouse gases.

Is the Alpha EVOKE 33 combi environmentally friendly?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

In the UK, central heating is responsible for 14% of greenhouse gas production. Domestic gas boilers emit large quantities of nitrogen dioxide in British cities.

Would installing a Alpha EVOKE 33 combi boiler in your home help combat climate change? What do the figures suggest?

By law, the minimum level of energy efficiency for boilers manufactured in the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the Alpha EVOKE 33 was given a 93% energy efficiency rating and a SEDBUK grading of "A".

The ERP (or Energy Related Products Directive) is a European regulation governing products which require energy to operate throughout their lives and encourages manufacturers to create products that are more environmentally friendly.

The legislation is designed to reduce the potential for harmful gas emissions during manufacturing and actual use right through to the point of final disposal.

For the Alpha EVOKE 33, the ERP rating is "A" for heat and "A" for hot water production.

How long is the warranty offered by the manufacturer for the Alpha EVOKE 33 boiler?

The Alpha EVOKE 33 boiler is covered by a parts and labour warranty of 7 years.
