Baxi 105 HE Combi Boiler

Unfortunately, the Baxi 105 HE Combi Boiler is no longer in production.

Indeed, there was a time when it was among the best in the market. However, that’s no longer the case. As expected of Baxi, they improved their product and manufactured even better and more efficient boilers (The Baxi 600 Series).

Nonetheless, that’s not to say the Baxi 105 HE is completely phased out. It still packs some punch and is even better than some of the boilers available in the market today.

Build

Despite its relatively old age, the Baxi 105 HE Combi Boiler is surprisingly good-looking. In its time, it was among the most compact combi boilers available in the market. While it’s true that it’s now slightly larger than modern models, it should be able to blend in quietly with your home’s decor.

Even back then, Baxi did their best to give their boilers a tidy look—Its buttons are nicely embedded for a neater presentation.

Finally, we have the 10 LED temperature, status, and fault diagnosis display that eases the servicing and maintenance process.

Fuel and efficiency

Unfortunately, the Baxi 105 HE Boiler isn’t among the most efficient combi boilers. It has an overall efficiency rating of 87.3% and scores a “B” in the SEDBUK Band levels.

Even so, it does keep up when it comes to central heating and hot water production—It has an ErP A-rating for both.

The main version runs on gas. Nonetheless, if your property is off the national gas grid, you’ll be happy to know that the Baxi 105 HE Combi Boiler also comes with an LPG variant.

Will it save you money on heating costs?

Not really. Unless you’re upgrading from an old boiler of more than 7 years. We advise you to consider a boiler from the Baxi 600 series.

Power output rating

As mentioned earlier, the Baxi 105 HE Combi Boiler still packs some punch. With a central heating and hot water max output rating of 31kW, it outshines even some of the most recent boilers available today.

Additionally, its impressive hot water flow rate of 12.1 litres per minute enables it to serve medium-sized to larger homes with up to 2 bathrooms.

Finally, we’d like to let you know that you can modulate its central heating output on a range of 11kWs to 31kWs.

Installation and servicing

Weighing 44kg, the Baxi 105 HE Combi Boiler is quite heavy compared to modern boilers. Nonetheless, it shouldn’t require more than two engineers to install. Speaking of installation, you can also install it in unventilated compartments.

Finally, like most Baxi boilers, it offers extensive and flexible flue options that allow vertical and horizontal configurations.
