What we think of the Baxi Megaflo System Compact GA

The Baxi Megaflo System Compact GA is a next generation system boiler that we highly recommend for your home heating system. It comes in six outputs; making it the perfect choice for many property types.

The beauty with this range of boilers within the Baxi Megaflo System Compact line-up, is its size. Traditionally this type of boiler, which uses a storage cylinder to keep the hot water ready for immediate use, is large and takes up a fair amount of space.

This, as its name suggests, prides itself on being compact and can happily sit inside a kitchen cabinet.

It has been developed to meet the demands of the normal modern home, which mostly make use of  a sealed heating system. But, unlike the traditional boiler, it has the pump and expansion tank built in, which is a great way of saving space. Within the range are six different individual models, which means you can pick the right level of output for you, from 12kW up to 32kW.

What’s more, because it has the separate storage tank, you will have access to a large quantity of hot water whenever you need it, without slowing down the effectiveness of the central heating system.

Getting a Competitive Boiler Quote

We recommend you get a few quotes in order to find the best boiler price. For instance, get a free quote from a national installer and compare it with one from a local boiler installer.  Also make sure your engineer is Gas Safe Registered.
