Which boiler combi or condensing? So, a boiler that takes its water supply directly from the mains and produces heating and hot water for your home from one compact unit is a Combi boiler and with the addition of a Flue Gas Heat Recovery System it becomes a condensing unit too. Thus making it a condensing combi boiler.
What is the difference between a condensing boiler and a combination boiler? Unlike an immersion heater, a combi boiler heats your water on demand, instead of storing it in a tank. … A condensing boiler is any boiler which uses condensing technology to make better use of the heat they generate from burning fuels such as gas or oil – so a combi boiler can also be a condensing boiler.
Why are condensing boilers better than non-condensing boilers? The main reason why condensing boilers are better than non-condensing models is that they are at least 25% more efficient. Their level of efficiency is achieved by using waste heat in flue gas to preheat the cold water entering the boiler, capturing more heat from the outside rather than the inside of a room.
Which best boilers combi condensing? All condensing boilers are at least 90% energy efficient, making them around 40% to 50% more efficient than old non-condensing models. They can reuse the heat in flue gases, are better for the environment and will help to reduce your heating bills.

Why hbr higher boiling point than hcl?
There are no hydrogen bonds between the molecules of either compound, since Br and I are not electronegative enough to polarise the molecules sufficiently. But since HI molecules contain more electrons than HBr, there are increased van der Waals forces in HI. For the same reason HBr has a higher boiling point than HCl.
