Alpha E-TEC 20S System Gas boiler frequently asked questions

What type of boiler is Alpha’s E-TEC 20S - system, regular or combi?

If you’re looking for a system boiler for your house or flat, you may wish to the consider the Alpha E-TEC 20S.

Ever since system boilers arrived on the market, they have been a popular choice in new homes. In the same way as regular boilers, they work along with a hot water cylinder, which is usually located in an airing cupboard. Since system boilers do not require a separate cold water tank, they appeal to some homeowners, especially if they intend to convert their loft in the future.

Their design includes (often built-in) circulating pumps to send hot water to your taps and radiators. They're also quicker and easier to install because you don't need to find room for and fit a water storage tank.

In addition, system boilers require programming for the flow of heat and hot water, which is not available right away. In any case, the cylinder keeps the water hot for use later, so you shouldn't have to wait for your bath as long as you set your timer and leave it on for long enough to heat sufficient water to use throughout the day.

Is the Alpha E-TEC 20S system boiler a suitable choice for my property?

You should make sure that the boiler you install in your property 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 has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Alpha E-TEC 20S system's output at 26 kW, which types of property would this Alpha E-TEC 20S System boiler be most appropriate for?

An experienced PlumbProud Gas Safe boiler installer would likely recommend that this Alpha E-TEC 20S System boiler would be suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What is the size of the Alpha E-TEC 20S?

The Alpha E-TEC 20S measures TBC mm tall, TBC mm wide, and TBC mm deep.

Alpha E-TEC 20S – condensing or non-condensing?

Condensing boilers like the Alpha E-TEC 20S 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 E-TEC 20S system rated as environmentally friendly?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to many homeowners.

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Would choosing the Alpha E-TEC 20S system help the environment? Let's see what the statistics 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 E-TEC 20S was given a 93% energy efficiency rating and a SEDBUK grading of "A".

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from their initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The Alpha E-TEC 20S has a rating of "A".

How long is the warranty period on the Alpha E-TEC 20S system boiler?

The Alpha E-TEC 20S boiler is provided with a parts and labour warranty lasting 10 years.

Alpha E-TEC 20S System Gas boiler frequently asked questions

Is the Alpha E-TEC 20S boiler a standard, combi or system model?

When looking for a system boiler for your house or flat, the Alpha E-TEC 20S might be a suitable option for you.

System boilers are suitable for larger homes where there is a higher-than-average demand for hot water and heating.

Through their use of a hot water cylinder, they provide hot water on demand during the day - as long as there's enough water left in the cylinder. Just let the boiler know when you want hot water for your radiators and taps via the programming panel and, subject to tank size and household usage, it'll be there for you.

Unlike heat only boilers, there is no requirement to find room in the attic for a cold water storage tank. System boilers are therefore quicker, easier and cheaper to install.

Should I choose a Alpha E-TEC 20S system boiler for my house or flat?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

Your boiler's output indicates the maximum amount of power available to it to heat the water you need to warm your radiators or when you want hot water from your taps. A higher output rate means that your boiler is capable of heating greater volumes of water.

If a boiler's output rate is too low, you'll often find that the water is not as hot as you want it to be. Too high, however, and you'll end up paying more for your gas than you should be.

The Alpha E-TEC 20S system boiler has an output rate of 26 kW, so which types of property would this be suitable for?

Most Gas Safe boiler installers would suggest that the most suitable type of property for installing this Alpha E-TEC 20S System boiler in would be larger properties including detached homes with 15 or more radiators and two or more bathrooms.


Alpha E-TEC 20S dimensions

The dimensions of the Alpha E-TEC 20S are TBC mm [H] x TBC mm [W] x TBC mm [D].

Is the Alpha E-TEC 20S non-condensing or condensing?

This Alpha E-TEC 20S is a condensing gas boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your gas bills as well as benefitting the wider environment.

Is the Alpha E-TEC 20S system boiler environmentally friendly?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

14% of the UK’s greenhouse gas production comes from central heating. In the bigger cities, gas boilers in particular are responsible for dangerous levels of nitrogen dioxide emissions.

Is the Alpha E-TEC 20S system an environmentally friendly choice for your home? Let’s have a look at the figures.

The energy efficiency rating for a boiler describes the amount of energy it uses and wastes during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "B" SEDBUK rating, 90%+ = "A" SEDBUK rating).

The Alpha E-TEC 20S scored an efficiency rating of 93% and a SEDBUK band rating of A.

The ERP (or Energy Related Products Directive) is European legislation affecting products that consume energy throughout their lifetime.

The aim is to encourage companies to create environmentally friendlier products that reduce harmful gas emissions during manufacturing and when in use by the end client, right through to their eventual disposal.

In the case of the Alpha E-TEC 20S, the ERP rating is "A".

What length of warranty does the Alpha E-TEC 20S come with?

Parts and labour charges incurred during a repair on the Alpha Alpha E-TEC 20S boiler are covered by a 10 year warranty.
