Biasi offers a lot of options for combi boilers in their RinNova Adaptive, Dina, and Basica range. Combi boilers provide both central heating and domestic hot water on demand. Combi boilers are ideal for homes with limited space as they do not need a separate hot water tank.
| Model | Efficiency | Warranty | Cost (supply only) | Suitable for |
|---|---|---|---|---|
| RinNova Adaptive 30 S | A | 7 years | £665 | Medium to large households (3-5 bedrooms, 2+ bathrooms) |
| Basica 28S | A | 5 years | £635 | Medium to large households (3-5 bedrooms, 2+ bathrooms) |
The prices are estimates based on our market research. Contact an installer for accurate figures.
Biasi has two options for system boilers, both suitable for medium to large households with high heating and hot water demand. System boilers come with an additional hot water cylinder to store hot water. Therefore, they require more space compared to a combi boiler.
You should choose the type of boiler—combi, system, or conventional boiler—after evaluating your house’s heating and hot water needs. Fitting a higher output boiler when it is not needed can result in high energy consumption and high energy bills. At the same time, a low output boiler might not be able to generate enough heating and hot water.
That is why you need a professional to handle the checks and installation. If you are worried about where to find the right installer, GreenMatch can help.

Can you finance Biasi boilers?
There are third-party retailers/suppliers in the UK who provide finance options for boilers. You will need to verify the supplier and check the payment plan to ensure you are getting a good deal, as some suppliers can have a high interest rate. Installers such as British Gas offer 0% interest for the first 3 years.
Biasi boilers review
Biasi boilers can be a good choice for homeowners on a budget, as the prices are lower compared to other popular brands. They offer a good range of options, but the ErP energy efficiency ratings for most of their boilers are ‘A’ (over 90%). At the same time, Biasi UK has a Trustpilot rating of 3.5. Here are some of the pros and cons of Biasi boilers:
Pros
- Affordability: The price range of £635 to £750 is one of the lowest on the market right now for A-rated boilers in the UK.
- Options for all household sizes: Biasi has options for combi boilers in all household sizes (small, medium, and large). Their system boilers are suitable for larger households.
- Compact design: The space-saving design is ideal for urban homes with less space.
Cons
- Less energy efficient: Biasi does not have the highest efficiency boilers. Compared to other highly energy-efficient A+ and A++ boilers in the market, Biasi lags behind.
- Short warranty: For some boiler ranges, Biasi offers only a 2-year warranty. Other competitor brands offer warranties of 7 to 12 years.
- Mixed customer reviews: Even though the Trustpilot rating is 3.5/5, some customers have had trouble with the company’s customer service and warranty claims.
How does Biasi compare to other boiler brands?
In the table below, you can see how Biasi performs when compared to its competitors.
| Feature | Biasi | Worcester Bosch | Alpha | Viessmann | Baxi |
|---|---|---|---|---|---|
| Price | £635 – £750 | £600 – £3,800 | £650 – £1,250 | £1,050 – £2,200 | £660 – £1,550 |
| Warranty | 2 to 7 years | 10 to 12 years | 7 to 13 years | 5 to 12 years | 2 to 10 years |
| Trustpilot rating | 3.5/5 | 4.6/5 | 4.7/5 | 4.4/5 | 4.6/5 |
Biasi is the most competitively priced brand on this list, although it does have the lowest customer rating and warranty. Quality wise, Biasi may not be able to compete with Worcester Bosch boilers, Alpha boilers, Baxi boilers or Viessmann boilers. But its A-rated boilers can do a decent job with heating and providing hot water on demand compared to the best combi boilers on the market.
