Looking at pure performance numbers, Ravenheat's CS System 3-20 gas boiler packs a serious punch with its 20kW maximum output.

Ravenheat CS System 3-20 Gas Boiler Pros and Cons
When evaluating Ravenheat's CS System 3-20 gas boiler, you'll find a mix of impressive features and significant limitations worth contemplating.
On the positive side, you'll benefit from its outstanding 92% efficiency rating and compact design that won't eat up valuable space. The large digital controls make temperature adjustments a breeze, while its whisper-quiet operation means you won't be disturbed by noisy heating.
However, there are some drawbacks to contemplate. The 2-year warranty falls short of industry standards, and the 20kW output mightn't cut it for larger homes.
You'll also need space for a separate hot water cylinder, and replacement parts can be tricky to find in certain areas.
The wall-mounted design and limited smart control options might also influence your decision, depending on your specific needs.
How Does The Ravenheat CS System 3-20 Gas Boiler Compare To Similar Models From Other Manufacturers?
