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

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

The Alpha E-TEC 20S is an option you may wish to consider if you’re looking for a system boiler for your house or flat.

Like heat only boilers, system boilers need a hot water cylinder to work - they're normally installed inside an airing or landing cupboard. However, since system boilers do not require a separate cold water tank, they are popular with homeowners who are planning to convert their loft or where attic space is already at a premium.

They're able to distribute the hot water you need to taps and radiators through (often built-in) circulating pumps and, because there's no water tank to install, they're easier, quicker and cheaper to install than heat only boilers. To get the heat and hot water you need when you need it, just use the control panel to program the times and days you want.

Should I install a Alpha E-TEC 20S system boiler in my home?

Whether this Alpha E-TEC 20S System 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 20S system is 26 kW, so which types of property would this model be appropriate for?

An experienced Gas Safe boiler installer would be likely to recommend that this Alpha E-TEC 20S System boiler is capable of providing heating and hot water to 15 or more radiators and two or more bathrooms and would therefore be most suitable for larger properties including detached homes.


Alpha E-TEC 20S dimensions

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

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

The Alpha E-TEC 20S is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

What energy efficiency ratings have been awarded to the Alpha E-TEC 20S system?

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.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Would installing a Alpha E-TEC 20S system 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 E-TEC 20S was given a 93% energy efficiency rating and a SEDBUK grading of "A".

The Energy Related Products Directive intends to encourage all manufacturers to reduce harmful gas emissions connected to the products they make, from the manufacturing stage to final disposal, including when they are in active use.

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

Does a Alpha E-TEC 20S system boiler come with a warranty period?

Alpha’s E-TEC 20S boiler includes a parts and labour warranty of 10 years.

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

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

The Alpha E-TEC 20S is worthy of consideration if you're looking for a system boiler for your flat or house.

System boilers need a hot water cylinder to work, with the most popular installation location for cylinders being in an airing or landing cupboard. Unlike heat only boilers though, they don't require a separate cold water tank to go in the attic, making them suitable if roof space is at a premium or if you're planning a loft conversion in the future.

System boilers use (often built-in) circulating pumps to distribute hot water to your taps and radiators. Fitting is cheaper and quicker too because you don't need to find room for a water tank. Unlike with a combi boiler, which heats water it draws from the mains instantly, you have to program a system boiler with the times you want hot water and heating.

Would the Alpha E-TEC 20S system be a suitable choice of boiler for my house or flat?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.

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

Most Gas Safe boiler installers would recommend that a boiler with this output level would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What size is a Alpha E-TEC 20S boiler?

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

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

Because of their increased energy efficiency, we recommend to all customers that they select one of the latest condensing boilers. Condensing boilers capture the heat from water vapour condensation and flue exhaust gases and recycle that heat to warm water entering the boiler (for example, from your radiators).

The Alpha E-TEC 20S is a condensing gas boiler and choosing this model will result in a likely substantial reduction in your fuel bills, particularly if you're replacing an older, inefficient, non-condensing boiler.

Is the Alpha E-TEC 20S system good for the environment?

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

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Would installing a Alpha E-TEC 20S system boiler in your home help combat climate change? What do the figures suggest?

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

Following testing, the Alpha E-TEC 20S was given an efficiency rating of 93% and a SEDBUK grading of "A".

The ERP (Energy Related Products Directive) is European legislation that aims to reduce the use of energy at all points during a product's life, from the point of manufacture to when it's in active use right through to final disposal.

The regulation aims to encourage manufacturers to create products that are more environmentally friendly and which reduce gas emissions associated with those products.

The ERP grading for the Alpha E-TEC 20S is "A".

If the Alpha E-TEC 20S system boiler breaks down, am I covered?

Alpha’s E-TEC 20S boiler includes a parts and labour warranty of 10 years.
