Alpha Boilers Review

Are Alpha Boilers Any Good?

Yes, Alpha boilers are a great option if you’re looking for a gas boiler that performs just as well as most premium brands but costs less.

Alpha Boiler Reviews

Although they’re still rather new to the UK market, boilers from Alpha are both reliable and budget-friendly, and their customer reviews attest to the same — as well as excellent service from the customer care team. In fact, Alpha has earned almost 5 stars on Trustpilot — an excellent ranking by any measure.

The Alpha Combi Boiler Range

Alpha has a range of models for each boiler type, including combi, regular, and system boilers.

The most popular products in the range are combi boilers, and include the following:

  • E-Tec Plus Combi
  • E-Tec Combi
  • Evoke Combi

Alpha Boiler Prices

Alpha tend to be priced into the lower end of the market. For instance, their flagship combi in 30kW form is only around £900. A lot of comparable brands would be charging this for a boiler with a much lower warranty.

What’s more, Alpha’s boilers are fitted with high-quality components (like a stainless steel heat exchanger) — something top-shelf brands typically offer for a premium.

The Problem With Alpha

The biggest problem with Alpha is that many independent merchants don’t stock them, as they’re not massively popular with installers or homeowners.

Instead, you tend to find that merchants focus on Worcester Bosch, Ideal Boilers, Baxi, Potterton or Vaillant.

If we compare the E-Tec Plus (10-year warranty) with an equivalent gas boiler from Worcester Bosch, it’s likely to be roughly £200 cheaper (not including installation).

So, you could save money if you can find an installer that fits them.

Alpha Boilers Installation Prices

For the 30kW Alpha E-Tec Plus, you’d be looking at £900 for the boiler and a few hundred more for general fittings, a flue and a filter. So the installation cost is likely to be in the region of £2,000.

Boiler Prices: Alpha Boilers vs Worcester Bosch

That’s comparable to something like the Worcester 30i when you use Heatable. As Heatable have great connections with most boiler manufacturers on the market, they get their boilers cheaper than average, and that’s reflected in the installation price; it’s going to run at a similar cost to boilers from Alpha, and you’ll get the same 10-year boiler warranty.

This makes a huge difference. You could be getting a Worcester installed for a similar price, rather than paying £200-400 more.

Basically, if you’ve already had a quote for an Alpha boiler from a local installer, it makes sense to get a comparison with another brand like Worcester, and you can do that here.

Alpha Boilers Warranty

Besides the kW output on offer, the main difference between the Alpha combination boiler range is the warranty on offer.

Ideally, you want to be aiming for a boiler with a warranty of 5-years or more.

That’s not to say there aren’t cheaper alternatives with a lower warranty. There are plenty of boilers being offered with much less, 2-years on many occasions.

Whilst you might save a few notes now by buying a boiler with a lower warranty, it will come back to bite you. Typically, a boiler manufacturer is going to offer a warranty that matches the durability of the product.

Why You Should Avoid Boilers With Short Warranty Terms

A 2-year warranty? Expect to be forking out for boiler repair bills soon. You’ll save £100-250 now on the overall installation cost but risk paying for repairs, or possibly even a replacement boiler in just a few years.

Alpha Boilers Warranty Table

The most popular boilers in the range come with the following warranties:

Boiler ModelWarranty
E-Tec Plus*Up to 13-years

*E-Tec Plus Warranty

A 10-year warranty is huge. Even better is the fact you can get an additional 1-year by fitting a Cyclone boiler filter.

Or, you can go the whole hog, fit a Premier Pack, and get an additional 3-years, so 13-years in total!

Which Size Alpha Boiler Do You Need?

When we say “size” here, we mean the boiler’s capacity in kW. Before you purchase a boiler, you must know what boiler size is suitable for your property.

Oversize your boiler, and you’ll be spending more than you need to on your energy bills.

Get one that’s too small, and you’ll be freezing.

Alternatives to Alpha Boilers

If you’d like to explore your options beyond Alpha, there are plenty of other boiler brands offering comparable products at roughly the same prices and with great warranties.

As we’ve mentioned, the likes of Worcester Bosch boilers can be found for a similar price from an online UK installer; you can check prices for them online using their price calculator.

FAQs About Alpha Boilers

Before wrapping up, we’d like to answer a few of your questions about boilers from Alpha.

Are Alpha boilers noisy?

Whilst they’re not known to be particularly noisy, like all boilers, Alpha boilers are vulnerable to problems that may cause them to be noisy.

The type of noise will often reveal the cause. For example, whistling, aka kettling, typically means that the boiler suffers from limescale build-up, and the hot water actually gets hotter than it should. The issue is preventable with annual boiler service and a limescale filter.

Likewise, a loud vibrating noise can mean that the boiler pump has seized.

To learn more about boiler noises and their causes, you can check out our guide here.

Who makes the Alpha combi boiler?

Boilers from Alpha are manufactured by Immergas, a market leader in heating appliances. The company is based in Italy, but operates in 30 nations worldwide.

Why does my Alpha boiler keep cutting out?

There’s a whole host of reasons why any boiler — including an Alpha boiler — may keep cutting out. Most commonly, a boiler locks out because it either can’t operate safely, or it’s unable to operate at all.

For example, an issue with the natural gas supply can prevent the boiler from maintaining a flame, whilst at the same creating a possible safety hazard.

Likewise, low system pressure can prevent the boiler from running properly, but also signify a leak somewhere in the central heating system.

To learn more about boiler lockout causes, you can read our guide here.

Why is my Alpha boiler flashing A and B?

It depends. If the A and B indicators are flashing at the same time, it means that there’s either a fan fault, or the flue is blocked. In either scenario, the boiler isn’t able to vent harmful exhaust fumes and can’t operate safely.

However, if A and B indicators are flashing alternatively, there’s insufficient pressure in the heating system and the boiler needs to be repressurised. More than likely, this means that there’s a leak somewhere in the central heating system that you’ll need to fix.

How do you fill an Alpha boiler?

Different boiler models have different filling mechanisms. Typically, there will either be an external filling loop through which you can fill up the boiler from the mains water supply.

Alternatively, there may be an internal filling mechanism which is already connected to the mains. In this scenario, you can typically turn a knob to fill the boiler to the correct pressure level.

If you’re not sure how to fill your Alpha boiler, refer to the owner’s manual — the information will be there for sure.
