Biasi boilers
Biasi has an active UK range, though what Ninja Plumbers sees far more of is its installed base of older units across London flats and terraces. Most Biasi work is repair and replacement rather than new installation.
The Biasi range
Biasi is an Italian boiler maker whose combis and system boilers were fitted widely at the budget end of the UK market, particularly in flats and smaller terraces. Riva, Garda and Inovia are the names most owners will recognise on the front. The brand still has a UK range, but we far more often meet boilers fitted years ago as the cheapest sensible option, now at an age where running costs and reliability start to matter.
What we see on Biasi boilers
- Older units where the economics favour replacement
- Standard combi failures — diverter, pressure, ignition
- Parts availability worth confirming on the oldest models
- Slow pressure loss through tired vessels and relief valves
- Budget installations with no system filter and little inhibitor
These are patterns Ninja Plumbers sees across the Biasi installed base, not a diagnosis of your boiler. Faults are identified on site before anything is quoted.
Servicing a Biasi
Newer models usually need a yearly service to keep the warranty valid, so check your warranty terms. For older ones, the yearly visit is about safety and spotting wear early, with a close look at the expansion vessel and pressure relief valve, since slow pressure loss is common at this age. Many budget installations went in without a magnetic filter, and that visit is a sensible moment to add one, priced separately.
Repair or replace?
On an older Biasi, weigh the cost of the failed part against the life left in the boiler. A diverter valve, sensor or relief valve on a working unit is usually worth replacing. A heat exchanger or main board past ten or twelve years usually is not; that money is better put towards a new boiler. If the Biasi was squeezed into an awkward spot, replacement is the chance to move it.

Biasi questions
- Is Biasi a brand you still see much of?
- In the installed base, yes — plenty of London properties have one. New installations are less common, so most of our Biasi work is keeping existing units going or replacing them when that stops making sense.
- How do I know which Biasi I have?
- The model name is usually on the front, with full details on the data badge. A photo of both on WhatsApp helps us bring the right parts, though we still confirm the fault on site before quoting.
- Is a new Biasi worth considering?
- It can be for a smaller flat on a tight budget, and we can install one. We would put it alongside other options at a similar price, so you can compare warranty and running costs.
- Do you repair and service Biasi boilers?
- Yes. Gas work is carried out by Gas Safe registered engineers, which is the legal requirement for working on any gas boiler regardless of make.
We work on every make
