Alpha E-TEC 33 Combi Gas boiler frequently asked questions

Alpha E-TEC 33 - combi, system or regular boiler?

Looking for a gas combi boiler for your house or flat? If you are, the Alpha E-TEC 33 boiler may be worth considering.

Combi boilers provide hot water or heating for your home on demand. You just need to turn the tap to get hot water or switch on the radiator and you’ll feel your home warm up within minutes.

In contrast, traditional boilers required either one or two large storage tanks to work - one to heat and keep water warm and the other to hold cold water for later heating. If the immersion tank was empty, it wasn’t uncommon to wait up to an hour for enough hot water to fill a bath, for example.

Combi boilers draw cold water from the mains and then heat it instantly whenever it's needed, all from one small unit.

The one disadvantage to combi boilers is that, if more than one point is in use at any one time (for example, if someone is taking a shower and another person turns on a hot water tap elsewhere in the property), water pressure, temperature and volume drop to both points.

Would the Alpha E-TEC 33 combi be a suitable boiler for my house or flat?

Whether this Alpha E-TEC 33 Combi boiler is right for where you live 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 of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.

A boiler whose output is too high will give you hot water and warm radiators but also higher gas bills, whereas a boiler whose output is too low will result in cheaper gas bills but the water might not always be as hot as you want it to be.

The output of the Alpha E-TEC 33 combi is 29 kW, so which types of property would this model be appropriate for?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Alpha E-TEC 33 Combi boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

If you are thinking about installing a combi boiler like the Alpha E-TEC 33 in your home, you should consider flow rates as well as output rates. This Alpha E-TEC 33 Combi boiler's flow rate is 14 L/m.

The flow rate indicates the maximum volume of water (measured in litres per minute) that your boiler can heat up and send to your radiators, taps and showers at any one time. The more taps and showers that could be in use simultaneously or the greater the number of radiators you have, the higher the flow rate you need.

However, you should establish what the mains pressure is at your property as a combi boiler can only heat the water that comes into your home.

For example, if your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate capacity. Typically, a power shower will require 10 litres of water per minute.

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.


How large is the Alpha E-TEC 33?

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

Is the Alpha E-TEC 33 a condensing or non-condensing boiler?

We strongly recommend that you choose a condensing boiler like the Alpha E-TEC 33 - the technology is improving every year so the newer the boiler, the better.

A condensing boiler captures and recycles the warmth still present in flue exhaust gases and water vapour condensation into heat, allowing it to perform more efficiently on tasks like heating the colder water returning from your radiators.

They also offer significant annual savings on household gas bills as well as being more environmentally friendly.

Is the Alpha E-TEC 33 combi good for the environment?

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.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

If you decide to install a Alpha E-TEC 33 combi in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are graded "B" and 90% and above is graded "A").

The Alpha E-TEC 33 was awarded an efficiency rating of 93% with a SEDBUK band rating of "A".

The Energy Related Products Directive (ERP) intends to reduce the amount of energy consumed by individual products over their entire lifetime, from the initial manufacturing process to final disposal and at all points in between.

The legislation is designed to encourage manufacturers to create products that are more environmentally friendly and which result in a reduction in harmful gas emissions.

The ERP rating for the Alpha E-TEC 33 is "A" for heat and "A" for hot water production.

If the Alpha E-TEC 33 combi boiler breaks down, am I covered?

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

Alpha E-TEC 33 Combi Gas boiler frequently asked questions

Which category of boiler does the Alpha E-TEC 33 fit into?

Suitable for a house or a flat, the Alpha E-TEC 33 combi boiler is worth considering if you want a combi boiler.

One of the reasons the combi boiler was introduced to Britain in the 1970s was because residential properties are among the smallest in the world. More traditional boilers require one or more large tanks to be stored around the home to function.

A combi boiler is a self-contained unit that draws water from the mains then heats and distributes it instantly and on demand - no tanks are needed.

They are the most popular type of boilers in the UK and offer only one major disadvantage - there is a maximum volume of water that can be heated at any one time. If that limit is exceeded by, for example, two people using a hot water tap at the same time, there will be a drop in water pressure, temperature and volume to both taps.

Is the Alpha E-TEC 33 combi suitable for my house or flat?

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

Most experienced boiler engineers would recommend that this Alpha E-TEC 33 Combi boiler would be suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

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 E-TEC 33 Combi boiler's flow rate is 14 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.


What size is the Alpha E-TEC 33 boiler?

The Alpha E-TEC 33 occupies a space of TBC mm high by TBC mm wide and TBC mm deep.

E-TEC 33 – condensing or non-condensing?

Condensing gas boilers like the Alpha E-TEC 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 Alpha E-TEC 33 combi boiler rated as environmentally friendly?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

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.

Is the Alpha E-TEC 33 combi boiler an environmentally friendly choice for your home? Here’s what the figures say.

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

Following its assessment, the Alpha E-TEC 33 was given an efficiency rating of 93% 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 E-TEC 33 is "A" for heat and "A" for water.

What is the warranty period for the Alpha E-TEC 33?

The parts and labour warranty offered with this Alpha E-TEC 33 Combi boiler covers you for 7 years.
