Condensing boilers typically have efficiency greater than 90%. This is accomplished by using the exhaust gas to preheat the cold water. This cause the water vapor in the exhaust to condense and hence the name. Manufactures like Harscho tout efficiency of 96% and above.
Condensing boilers are designed to increase energy efficiency by using the wasted heat from flue gases to heat water up before it even reaches the main boiler. These boilers are very energy efficient and are mandatory or preferred in many countries.
Condensing boilers do work very well and are quite efficient. They will take several years to recoup their price, however. If it is only for savings, you should consider the length of time involved.
The most relevant company that does boiler installations nationwide is Norther Gas and Heating. From full Gas Central Heating Systems to replacement Condensing Boilers and Combi boilers. All our boilers are 'A' rated energy efficient boilers.
Hi. No, these are not the same thing. A Combi-boiler can be a type of condensing boiler that does not need a tank and just heats the water on demand. A combi boiler can be of a condenisng type - in other words there are combi boilers that are condensing boilers. However, there are many types of condensing boiler that do have a holding tank, so not all condensing boilers are combi-boilers. By the way, if you are looking into a combi boiler, make sure that your installer has factored in your likely hot water usage and that this type of system will supply you what you need even at peak times.
British gas boilers are extremely efficient, especially models manufactured in the last decade. New parliamentary regulations have required these boilers to become more efficient.

furnace highest rating is 97 % efficient for a residential model. This is known as a condensing furnace.

Baseboard is actually very efficient. Baseboard can be used on 99% efficient boilers but also 60% efficient boilers. The boiler you are using may not be efficient at all. If you have large heating bills, make sure your building is insulated and the boiler is running correctly. If your boiler is 80% efficient, remember 20 cents of your dollar is going out the chimney!
Electric heating boilers can be a useful alternative to gas and other conventional furnaces. LPG and oil-fired boilers are also very efficient. Biomass boilers are also becoming popular.
