What is the best combi boiler overall for value and reliability?

Update – Thankyou all very much for taking the time to post your honest opinions – I’ll be checking out your recommendations.
Most appreciated, Shona

Looking to replace my dad’s boiler. Only had one quote so far which is based on a Ferroli boiler however when i research them online they are universally panned by almost everyone – clients and installers although I guess they are a source of work for the installers!! Fairly highly recommended seems to be Vaillent Ecotek but I think this is at the higher cost end of the scale.
Is there a boiler that has good reliability at a reasonable price or is it better to go with a big name like Vaillent or Worcester and pay more initially? My dad has a servicing contract with Scottish Gas so maintenance isn’t an issue but all the same he doesn’t want to be calling them out every 5 mins to repair it.
When I get quotes I want to make sure I’m comparing like with like and not getting a cheaper quote because it’s based on a rubbish boiler.
Boiler is for a 3 bed house with one bathroom.



When it comes to choosing a combi boiler, there are several factors to consider, including reliability, efficiency, cost, and warranty. Based on my knowledge, here are some recommendations for reliable and reasonably priced combi boilers:

1. Viessmann Vitodens: Viessmann is a German brand known for its high-quality and durable boilers. The Vitodens range is highly regarded for its reliability and efficiency. While they may be slightly more expensive than some other brands, they are known to have a long lifespan and lower maintenance costs in the long run.

2. Baxi EcoBlue: Baxi is a reputable British brand that offers good value for money. The EcoBlue range is energy-efficient and has a good reputation for reliability. Baxi boilers are generally more affordable than some of the premium brands.

3. Worcester Bosch Greenstar: Worcester Bosch is a respected brand in the UK, and their Greenstar range is known for its quality and reliability. While they may be more expensive than some other options, they often come with longer warranties and have a reputation for durability.

4. Ideal Logic: Ideal is another British brand that offers good value for money. The Logic range is reliable and energy-efficient, making it a popular choice for homeowners on a budget.

5. Vaillant EcoTEC: As you mentioned, Vaillant is a well-known and reputable brand. The EcoTEC range is energy-efficient and reliable, but it tends to be more expensive than some other options.

When choosing a boiler, it’s essential to consider the installation cost, as well as the upfront cost of the boiler itself. While a more expensive boiler may seem like a significant investment initially, it could save you money in the long run due to lower maintenance costs and greater energy efficiency.

It’s also recommended to get multiple quotes from reputable installers and compare the overall costs, including the boiler, installation, and any additional fees. Don’t be tempted by the cheapest quote if it’s based on a boiler with a questionable reputation.

Finally, make sure to research the warranty and after-sales support offered by the manufacturer, as this can provide peace of mind and protection in case of any issues.
