Build

As expected of Baxi, they made a compact boiler that won’t occupy much of your living space. Additionally, its compactness is further highlighted by the fact that it’s a wall-mounted unit. It will quietly fit into most kitchen cabinets.

For the design, Baxi decided to keep it simple. Even though it only comes in white, the Baxi 624 Combi Boiler has a nice finish and satisfying curves. Additionally, its controls and dials are embedded into the casing to give it a neat look.

Speaking of dials, it has a reset button, central heating temperature control, domestic hot water temperature control, and a system water pressure gauge.

We also have a simple LCD that will display fault codes, temperature settings, and the system’s overall status.

The Baxi 624 is durable thanks to its stainless steel heat exchanger and brass hydraulics block. It’s important since the market is saturated with plastic boilers that don’t last as long.

Finally, we love the fact that the boiler has its pipes neatly hidden behind its casing,

Fuel and efficiency

With an overall efficiency rating of 93%, the Baxi 624 Combi Boiler is up there among the best in the market. Additionally, it’s also ErP A-rated for both central heating and hot water production—With this unit, you’ll save money on heating costs and reduce your home’s carbon footprint.

Although it mainly runs on British Gas, it can also operate on a 20% hydrogen blend.

Power output rating

The Baxi 624 Combi Boiler is the least powerful in its boiler range. Some might see that as a disadvantage. Fortunately, that’s not the case. When buying a boiler, you need to be wary of sizing—An oversized boiler can be as detrimental as an undersized boiler.

If you live in a relatively small household (like a studio), then the Baxi 624 is perfect. It has a reliable central heating output of 21.2kW that will keep you warm during the harsh winters. Also, it has a domestic hot water output of 25.8kW that will suffice your shower demands. It’s also comforting to know it has a water flow rate of 10.2 litres per minute and can operate up to 10 radiators.

If you live in a relatively larger household with 2 bathrooms or more, then you should consider the Baxi 630 and 636 Combi Boilers.
