Ravenheat Boilers: Compact and CSI Range
Ravenheat is a UK-based brand known for producing genuinely compact boilers suited to flats and tight installation spaces.
Ravenheat is a UK-based brand known for producing genuinely compact boilers suited to flats and tight installation spaces. We service and repair the Compact and CSI ranges as part of general gas work.
How the range is built
Ravenheat's focus on a small chassis footprint means components are densely packed, which we factor into how much time we allow for a repair visit.
What we see go wrong
PCB and pump faults are the most frequent, along with condensate blockages given how tightly some units are boxed in.
Servicing and parts
Being a UK manufacturer helps parts availability for current models, though very compact older units can have less common component sizes.
What matters most on a compact boiler like this
- Access room for servicing given the tight chassis
- Condensate routing in confined installation spaces
- Pump and PCB condition on ageing units
- Confirming ventilation is adequate for the cupboard it sits in

Questions we get asked
Why are Ravenheat boilers so small?
The brand specifically targets compact installations such as kitchen cupboards and flats, which shapes the whole chassis design.
Does a compact boiler make repairs harder?
Sometimes access takes more care, but the fault-finding process itself is the same as any gas boiler.
Are Ravenheat parts easy to source?
Reasonably so for current models given it's a UK manufacturer, though very old or discontinued units can be trickier.
