Alpha EVOKE 33 Combi Gas boiler frequently asked questions

Alpha EVOKE 33 - combi, system or regular boiler?

The Alpha EVOKE 33 is a gas combi boiler.

Traditional boilers have one or two tanks - one holds hot water to keep it warm and the other water for later heating. Because UK residential property is among some of the smallest in the world, manufacturers introduced combi boilers and the heat pumps that go in them in the 1970s to reduce the amount of space boilers needed to take up.

The hot water needed for your radiators and taps is available on demand when you have a combi boiler. Combi boilers use technology located within the boiler to heat cold water, which it draws from the mains, and to distribute hot water where it's needed around your home.

A combi boiler, however, has the disadvantage of a maximum capacity for the amount of water it can heat. The result is that if someone uses the shower while another uses a hot water tap simultaneously, the amount of water reaching each point falls, causing water pressure to drop.

Should I install a Alpha EVOKE 33 combi boiler in my home?

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

Your boiler’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your gas than you need to.

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

A Gas Safe boiler installer would say that this Alpha EVOKE 33 Combi boiler's level of output makes it suitable for installing in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

The Alpha EVOKE 33 is a combi boiler, which that means that you need to take the flow rate (measured in litres per minute) into account as well as the output rate. This Alpha EVOKE 33 Combi boiler's flow rate is 14 L/m.

Combis draw water from the mains, instantly heating and distributing it where it's needed - taps, radiators, bathrooms, and so on.

However, this means that the flow rate of a boiler may effectively be capped by the flow rate of the mains water supply. For example, if your mains pressure is 12l/m, that is the maximum flow rate that your boiler can achieve even if you choose a boiler with a flow rate of 18l/m.

In addition, if your home has more than one bathroom, a high number of radiators, and more than one member of your household wants to use hot water at the same time regularly, the flow rate of both the boiler and the mains water pressure may not be high enough.

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 33 dimensions

The Alpha EVOKE 33 has the following dimensions - TBC mm high, TBC mm wide, and TBC mm deep.

Is the Alpha EVOKE 33 a condensing or non-condensing boiler?

We recommend the Alpha EVOKE 33 as it is a modern condensing gas boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more gas.

Condensing boilers significantly reduce your quarterly gas costs and they're better for the environment.

What energy efficiency ratings have been awarded to the Alpha EVOKE 33 combi?

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they heat their homes.

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Would the environmental impact of installing a Alpha EVOKE 33 combi in your home be positive? Let's look at the numbers.

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 Alpha EVOKE 33 was given an efficiency rating of 93% and 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 33 has a rating of "A" for heat and "A" for water.

How long is the warranty period on the Alpha EVOKE 33 combi boiler?

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

Alpha EVOKE 33 Combi Gas boiler frequently asked questions

What type of boiler is the Alpha EVOKE 33 - regular, system or combi?

The Alpha EVOKE 33 is a gas combi boiler.

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.

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 - the "output".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

The output of the Alpha EVOKE 33 combi is 29 kW kilowatts, so which types of property would this be appropriate for?

Most experienced Gas Safe boiler installers would suggest that the Alpha EVOKE 33 combi boiler would be a suitable choice for installation in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

In addition to output rates, you need to consider a combi boiler's flow rate when making your choice.

The flow rate of your boiler dictates the maximum volume of water (measured in litres per minute) that it can heat and distribute to your taps, showers and radiators at any one time.

However, a combi boiler like the Alpha EVOKE 33 can only heat and deliver water at the rate at which it actually enters your property. For this reason, you should also find out what the mains pressure to your house is before purchasing a boiler.

It's pointless spending more money on a boiler with a 17l/m flow rate if the local water pressure is 11l/m. To give you an indication of average water demand, a power shower typically requires 12 litres of water per minute and a basin tap 4-8 litres. This Alpha EVOKE 33 Combi boiler's flow rate is 14 L/m.

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 33 size

The size of the Alpha EVOKE 33 boiler is TBC mm high, TBC mm wide, and TBC mm deep.

Is the 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?

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.

Will installing a Alpha EVOKE 33 combi be a positive contribution to the environment? Let's see what the experts say.

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 (Energy Related Products Directive) applies to all products that consume energy at any time in their lifetime, from manufacture to disposal and all points in between.

This European legislation intends to encourage manufacturers to offer end users products that are better for the environment through the creation of fewer harmful gas emissions at all points of a product's life cycle.

The ERP rating for the Alpha EVOKE 33 is "A" for heat and "A" for water.

How long is the warranty period on the Alpha EVOKE 33 combi boiler?

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