Condensing Boilers Efficiency Claims

103 5
Condensing boilers use the heat that normally escapes through the unit's flue and recirculates it to keep the device working.
This means that a condensing boiler uses less fuel to operate than normal device that create hot water for residential homes do.
The manufacturers of condensing boilers almost unanimously agree that these devices are more efficient than the average systems are.
The efficiency rating on the majority of these devices is a whopping ninety eight percent.
This is an increase of at least eighteen percent over the efficiency of the normal water heating appliances.
The increase could be as great as twenty eight percent more than some of the older versions of this type of appliance provided.
A lot of the devices that are not condensing boilers can be made to condense through changes in the controls to the device.
This will drastically reduce the amount of fuel consumption you have for this appliance.
The real problem with changing a normal water heater into condensing boilers is that the components of the device that are formed from cast-iron or mild steel will quickly be corroded by the condensation that is form.
This condensation is slightly acidic and causes damage to most metals and for this reason stainless steel is generally used to build these heat exchangers.
The efficiency rating of the condensing boilers is affected in a large way by the efficiency of the heat transfer.
It is also dependent in a large way on the size of the boiler compared to the output of the unit and the size of the emitter compared to the output of the device.
When it comes to the thermal efficiency of these devices the design of the system and the installation of the system are critical elements.
The radiation and the British thermal units per hour of output will determine the overall efficiency you will receive.
The radiator design will play a part in the overall performance efficiency of the device.
These units were first put to use in the Netherlands.
After that they quickly gained in popularity throughout Europe.
In North America it is taking longer for the devices to become as popular, but the fact that the people of the United States can receive a reduction in their taxes for installing these devices is increasing their popularity.
These items are rated by all authorities as being energy star rated appliances.
They require far less fuel than the older versions did and they make a better use of the fuel that they do use.
There is less heat escaping from the unit and more hot water is produced for each dollar that is spent in operation.
Most people can relate to the fact that they will be saving money when they start to use these units to replace their older style appliances.
It surprises some people when they find out that the cost of replacing their older models with the new models is often recovered within the first two years by the reduced utility bills.
