With our combi boiler ratings, you can cut through all of the sales hype and find the greatest value. We search the technical literature and use our heating system service experience to create our unique rating system. It truly is like taking a repairman with you while you shop! These ratings are for gas-fired boilers that provide hot water for central heating as well as for showers, etc.
Our top pick is the ECOGEN from BAXI. It is one of the most innovative direct combi boilers on the market. It is a micro-chp unit as well as a high efficiency heating system. Installation is basically the same as a traditional boiler but this unit produces up to 1 kilowatt of electricity at the same time. baxi.co.uk

AIRFEL------------<1*--------NA--------NA
This brand is a part of DAIKIN GLOBAL and is made in Turkey. The DIGIFEL models are available in two sizes and have a digital LCD display control panel.

ALARKO----------<1*--------NA--------NA
This brand is made and sold in Turkey. The SERADENS models are available in three sizes and feature full modulation with a LCD digital control panel. They have stainless steel heat exchangers for durability but the warranty on the units is not as good as many other brands. alarko-carrier.com.tr
ALPHA------------<1*--------NA--------3*
This brand is a subsidiary of IMMERGAS and is available in the U.K. The InTEC2 CE model is a direct combi that is available in three sizes but the warranty is not as good as some other brands. The InTec2 X model is their "entry level" direct combi and its warranty is even worse (it gets a <1* rating). The Intec2 SE is a system unit that requires an optional diverter kit for domestic hot water priority but it is backed by a good warranty. All of the units use durable stainless steel heat exchangers. alpha-innovation.co.uk
ACV---------------NA-------<1*-------<1*
These units use tank-in-tank technology where a stainless steel tank is inside of another tank. This provides a lot of surface area for heat transfer and therefore rapid recovery. The units have advanced programmable controls that are internet ready for maximum flexibility. The HEATMASTER series are floor standing units and the PRESTIGE EXCELLENCE series are wall hung units. The PRESTIGE SOLO series units are wall hung system boilers. The guarantee on these units is not very good when compared to other brands. acv.com
