Alpha E-TEC 33 Combi Gas boiler frequently asked questions

Is the Alpha E-TEC 33 boiler a combi, regular or a system 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.

In many properties, combi boilers are more suitable than traditional types of boiler. Combi boilers heat water instantly on demand, which they draw directly from the mains supply, removing the need for storage tanks that can take up valuable space in your home.

A combi boiler is often the right choice for a smaller property, particularly if your home doesn't have a useable loft. As water is heated and delivered immediately rather than being kept warm for hours in an immersion tank, combi boilers reduce gas usage, thereby minimising your heating costs.

The main disadvantage of combi boilers is that they can only heat a certain amount of water at any one time. This means that, if two people are using different taps or showers within your home at the same time, the flow of heated water to each will be reduced, as will the water pressure and temperature.

Is the Alpha E-TEC 33 combi 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 the boiler is - it means how big its "output" is.

This Alpha E-TEC 33 Combi boiler gets its power from gas and the power it's capable of producing is measured in kilowatts - the output rate is actually a kilowatt rate. The higher the output rate, the more kilowatts a boiler can use when heating water.

If you choose a boiler whose output rate is too low, it may not have enough power to make your water as hot as you would like. If you choose a boiler whose output rate is too high, you won't have to put up with lukewarm water but you will face higher gas bills.

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

To most boiler engineers, the Alpha E-TEC 33 combi E-TEC would be most 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.


Alpha E-TEC 33 dimensions

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

E-TEC 33 – non-condensing or condensing?

We recommend that you select a condensing boiler like the Alpha E-TEC gas Alpha E-TEC 33 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 environmentally friendly is the Alpha E-TEC 33 combi?

As more of us become concerned by the effects of climate change, the damage we do to the environment by heating our homes has emerged as an important issue for many homeowners.

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.

Would choosing a Alpha E-TEC 33 combi help in the fight against climate change? What do the performance statistics suggest?

All boilers manufactured after April 2018 in the UK must be rated as an “A” on the SEDBUK grading system, subject to a minimum energy efficiency rating of 92% or above. Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Alpha E-TEC 33 has an efficiency rating of 93% with a SEDBUK grade of "A".

The Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

For the Alpha E-TEC 33, the ERP Heat rating is "A" and the ERP Water rating is "A".

How many years does the warranty period cover on a Alpha E-TEC 33 boiler?

The Alpha E-TEC 33 boiler is provided with a parts and labour warranty lasting 7 years.

Alpha E-TEC 33 Combi Gas boiler frequently asked questions

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

Looking for a gas combi boiler for your flat or house? Then the Alpha E-TEC 33 may be an option you should consider.

In older British homes, traditional boilers required you to find room for one or more storage tanks. One tank would keep hot water warm and the other stored cold water for later heating. Manufacturers introduced combi boilers to the UK in the 1970s so that homeowners could get the warmth and hot water they needed without having to sacrifice too much valuable space – remember that residential property in this country is among the smallest in the Western world.

Combi boilers deliver hot water to your radiators and taps using water they draw directly from the mains supply. As mains water travels through a combi boiler, the technology within it heats the cold water instantly and on demand. The hot water is then distributed throughout your house.

Combi boilers have one drawback, however: they can only heat a certain amount of water within a given time. For example, if someone uses the shower and another person uses the hot water tap at the same time, water pressure drops because water reaches each point differently.

Is a Alpha E-TEC 33 combi the right boiler for my house or flat?

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 E-TEC 33 combi is 29 kW kilowatts, so which types of property would this be appropriate for?

A PlumbProud boiler engineer would almost certainly recommend that this Alpha E-TEC 33 Combi boiler is most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

You'll also need to be sure to choose a combi boiler with the right flow rate for your home.

The flow rate indicates the maximum volume of hot water (measured in litres per minute) that your boiler can distribute at any given time. This means that if you and your family are likely to be using several taps and showers simultaneously or you have a lot of radiators, you need a boiler with a high flow rate. This Alpha E-TEC 33 Combi boiler's flow rate is 14 L/m.

As with all combi boilers, the Alpha E-TEC 33 is only able to heat and distribute water at the rate at which it actually enters your property.

For this reason, you shouldn't purchase a boiler with a very high flow rate if the flow rate in your mains pipes is lower because the extra capacity 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.


Making space for the Alpha E-TEC 33

The dimensions of the Alpha E-TEC 33 are TBC mm tall, TBC mm wide, and TBC mm deep.

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

The Alpha E-TEC 33 is a condensing gas boiler - in fact, we recommend that you select this model or one of the latest condensing boilers on the market as the technology continues to improve over time.

Condensing boilers capture the heat still present in the flue exhaust gases and water vapour condensation created when the gas is burned and they recycle this back into the heating system to warm up the cold water re-entering the boiler from your radiators.

They're much more environmentally friendly and installing one results in much lower annual gas bills.

How does the Alpha E-TEC 33 combi rate environmentally?

Many homeowners are now worried about climate change and the damage they do to the environment from heating their homes has become a subject of increasing concern.

With central heating being responsible for 14% of greenhouse gas emissions in the UK, your choice of boiler matters. Gas boilers are also responsible for the significant atmospheric volumes of dangerous nitrogen dioxide emissions in larger British cities.

Will you be helping the environment if you decide to install a Alpha E-TEC 33 combi in your home? Let’s look at the figures.

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Alpha E-TEC 33 was awarded an efficiency rating of "93%", equivalent to a "A" rating on the SEDBUK system.

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

What is the length of the warranty on the Alpha E-TEC 33?

A parts and labour warranty of 7 years is included with the Alpha Alpha E-TEC 33 boiler.
