What is meant by a Condensing Boilers?
The terms condensing and non-condensing can be confusing to people shopping for a new boiler.
Presently, it is stated by law that new boilers must use condensing technology. In short, you don’t have to worry about getting a condensing boiler.
Condensing is not a type of boiler, but rather technical feature. In a Condensing boiler you get a much bigger heat exchanger. They also produce additional heat from the fuel. The same fuel that would have been wasted in a non- Condensing boiler. As a result, they are more efficient.
non-condensing boilers are less efficient by 50% since a lot of heat was lost in the combustion exhaust gases. On the other hand, new boilers would capture this heat and use it to heat water.
condensing boilers are energy efficient by 90%. They use excess energy to heat your property. Not to mention, they are environmentally friendly and reduce your heating bill.
What is the output range for Worcester Bosch combi boilers?
Combi boilers are perfect for small or medium sized homes. They are compact and do not require plenty of space. They can supply hot water for up to two bathrooms. It is important to make sure that your combi boiler is the right output size for your home.
In order to calculate the right output size you need to put in mind the number of radiators you have in your home. For each radiator, you will need 1.5 – 2kW of power.
The Greenstar 4000 combi boiler has an output of 25 – 30 kW and can support up to 15 radiators.
