If you’re looking for a reliable heating system that will keep your home warm and cosy, Worcester Bosch boilers are a great option with their award-winning boilers and excellent customer service.

With an output of either 35 or 43kW, this particular model is best suited for larger homes but Vaillant also offers other models in this range that are suitable for smaller properties. Aside from its power, the ecoTEC exclusive combi boiler comes with a handy ‘smart’ feature that tracks your heating usage and automatically lowers the power to a mere 16% of its full capacity when you don’t need much heat.

If you choose to install this device, warranties between 2 and 10 years are available depending on whom you get to install it.

  • Vaillant’s ecoTEC range is perfect for larger homes
  • The ecoTEC exclusive combi boiler won the 2018 Housebuilder Products Awards
  • Its ‘smart’ feature tracks your heating usage and can lower power when not needed

3. Alpha Boilers

You may be pleasantly surprised to know that Alpha boilers offer a 10-year warranty, matching some of the more expensive brands. This is a testament to the quality and reliability of their products, despite being considered a budget option.

One impressive feature of Alpha boilers is their use of stainless-steel heat exchangers, which are typically found in premium brands like Viessmann.

Alpha’s range of combi boilers, such as the E-Tec, Intec, or Evoke, are priced between £520 and £2,500. With a maximum warranty period of 10 years when installed by Heatable, Alpha proves to be an excellent choice for those wanting the best central heating boiler on a budget.

4. Ideal Boilers

Ideal Boilers is a well-known brand in the UK home boiler market, with a history dating back to 1906. The brand has built an excellent reputation for itself over the years, thanks to its range of boilers that cater to different budgets and preferences.

From budget-friendly models to more high-end varieties with advanced features, Ideal Boilers has something for everyone. In addition to its product offerings, Ideal Boilers also sponsors West Brom football team.

While this may seem like an unrelated fact, it speaks volumes about the brand’s commitment to excellence and reliability – qualities that are essential in both sports and boilers.

As we look towards 2023, Ideal Boilers remains a trusted manufacturer for those seeking quality boilers that are built to last.

5. Viessmann Boilers

Looking for a reliable heating system that offers technically brilliant boilers with up to a 10-year warranty? Viessmann boilers may be the perfect choice for you.

With its German engineering and simple, crisp designs, Viessmann has dominated the European boiler market. Now, they’re building a solid reputation in the UK for both reliability and quality.

One of the main advantages of choosing Viessmann over other brands is their use of stainless steel heat exchangers instead of aluminium, which is commonly used by other boiler manufacturers. This component is crucial in generating hot water, and some brands choose to neglect it by constructing them from lesser materials at the expense of longevity.

But with Viessmann’s durable stainless steel heat exchangers, they are better able to deal with sludge and withstand years of corrosion, two major culprits of boiler faults and failures.

If you prioritize quality above all else when it comes to your heating system, then Viessmann may be the right brand for you and your home.

6. Baxi Boilers

Moving on from Vaillant boilers, another brand worth considering for your boiler replacement is Baxi. While not as well-known as some of the top-shelf brands like Worcester Bosch and Ideal, Baxi’s quality rivals theirs at a notably lower price point.

Baxi offers various types of boilers, including system, regular, and combi models. The Baxi 800 Combi is a standout choice among their range, with features such as a magnetic filter to keep radiators clear of sludge and an easy-fill permanent filling link.

With parts and labor covered by a 10-year warranty, this model is compact enough to fit into most kitchen cupboards and comes in three different sizes. When combined with installation costs, expect to pay anywhere between £1,500 and £2,200 depending on the model chosen.

7. Glow Worm Boilers

Looking for a budget-friendly option for your next boiler replacement? Glow-Worm boilers may be worth considering, with their low prices and energy-efficient technology.

While they may not have the same level of reliability as some other top brands like Vaillant or Worcester, they do offer warranties ranging from 2 to 5 years on their products. This makes them a cost-effective short-term solution.

Glow-Worm boilers are regularly priced as ‘special offers’ at local plumbing merchants, which means they are cheaper to buy and install than many other brands. They offer a range of boilers including combi, regular, and system models that incorporate the latest technology to help increase efficiency and reduce fuel wastage.

If you’re looking for an energy-efficient boiler on a budget, Glow-Worm may be an ideal option while also easing up on your carbon footprint.

8. Potterton Boilers

When it comes to choosing a boiler brand, Potterton may offer technically impressive options, but their reduced warranty period of only 2 years may not provide the peace of mind that many buyers are seeking.

In the past, Potterton was known for manufacturing condensing boilers for the premium end of the market only, but they’ve recently launched a range of budget boilers. This has resulted in some models having a warranty period as short as 2 years, which is significantly lower than other top brands in the market.

Despite their short warranty periods on most models, Potterton does offer some brilliant combi boiler options such as Promax, Titanium, Promax Ultra, Assure and Gold. Their prices range between £675 and £1,350.

If you’re looking into buying a Potterton boiler or already have one installed in your home and are experiencing issues with it, there are resources available online to help troubleshoot common problems. However, it’s important to weigh up all your options when considering different boiler brands and make an informed decision based on factors such as energy efficiency ratings, warranties offered and customer reviews before making your purchase.

9. Intergas Boilers

Moving on from Potterton boilers, let’s take a look at Intergas – a relatively new brand in the UK market that boasts of offering the fewest moving parts among its rivals.

The latest Intergas boilers are sleek and modern with contemporary designs and user-friendly features like remote control systems. They offer two combi ranges, Rapid and Compact, which come with warranties ranging from three to seven years depending on the model.

Intergas boilers are priced between £630 and £1,040, making them an affordable option for those looking for an efficient condensing boiler that looks good too.

Although they haven’t received any Which? Best Buy awards yet, their products have received positive reviews from customers who appreciate their reliability and energy efficiency ratings. With warranty periods of up to ten years, Intergas boilers can be a reliable choice for homeowners looking to upgrade their heating system in 2023.

10. Vokera Boilers

Vokera may not be a well-known brand compared to Worcester Bosch or Vaillant, but it shouldn’t be overlooked. Their boilers are loved by engineers for their simplicity and homeowners for their affordable prices. If you’re on a tight budget and looking for a reliable boiler, Vokera could be the perfect solution.

Their models include the Evolve C, Unica i, Vision Plus, Vision C and Compact A, offering warranties ranging from 2 to 7 years depending on the model you choose. While their names might not be as catchy as other brands, Vokera’s boilers are still decent in terms of quality.

With prices ranging from £1,200 to £2,100 when fitted, they offer an affordable alternative without sacrificing reliability. So if you want to save money while still having peace of mind with a warranty up to 10 years in length, Vokera is worth considering for your boiler replacement needs.

Factors to consider when picking the best boiler brand

Before you make a decision on which boiler brand to choose, it’s important for you to consider several factors. Here are the top four areas that we recommend focusing on:

  1. Warranty period: Make sure the brand offers a decent warranty period, which will give you peace of mind in case something goes wrong with your boiler.
  2. Customer reviews: Read customer reviews online to get an idea of how reliable and efficient the boilers are in real-world situations.
  3. Awards and accolades: Look for brands that have won awards or received recognition from respected organizations such as Which? Best Buy Awards.
  4. Efficiency ratings: Check the energy efficiency ratings of each brand’s boilers, as this can impact your energy bills and overall carbon footprint.

Price range is also an important consideration, but keep in mind that paying more upfront for a high-quality boiler could save you money over time due to increased efficiency and longevity.

When choosing a boiler brand, it’s crucial to do your research and take these factors into account before making a decision. By doing so, you’ll be able to find a boiler that meets your specific needs while offering great value for money.

What is the lifespan of a boiler and when should it be replaced?

Boilers typically last between 10 and 15 years with proper maintenance. However, when should you replace your boiler?

The Nest scheme in Wales offers free impartial advice and home energy efficiency improvements, including a new boiler, central heating, insulation, or solar panels, to low-income homeowners and private-sector tenants receiving means-tested benefits or with chronic respiratory, circulatory, or mental health conditions.

What are the most common boiler problems and how can they be prevented?

Have you ever experienced a boiler breakdown or malfunction? It can be frustrating and uncomfortable, but luckily many common problems can be prevented with proper maintenance.

How often should a boiler be serviced and by whom?

When it comes to servicing your boiler, it’s important to schedule regular maintenance appointments with a qualified professional. The frequency of these appointments will depend on the age and condition of your boiler, as well as the manufacturer’s recommendations.

During these appointments, a technician will inspect and clean various components of the boiler to ensure that it’s running safely and efficiently.
