Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.
.
Considering this, what should the flow and return temperatures for condensing boilers?
The dew point is at 55 degrees, and for the boiler to condense the temperature of the water that returns to the boiler must be 55 degrees or below. Many are set up with a flow and return temperature of 70 degrees.
Subsequently, question is, do oil fired boilers have a pilot light? Oil boilers have an electronic ignition system - if there is no pilot light displayed try to reset the button in order to re-start the boiler. (On some models this button is known as a limit button).
In this way, what is a condenser oil boiler?
Converting fuel oil into heat Our oil condensing boilers are reliable and efficient heating and hot water solutions. They extract nearly all of the heat contained in the flue gases, turning this into additional heating energy and therefore minimising waste.
How does a Worcester condensing boiler work?
Condensing boilers work by recovering the waste heat which is expelled through the flue system of a non-condensing boiler and passing it through a second heat exchanger where it extracts additional heat. This is why it makes such good sense to switch to an award-winning Worcester boiler.
Related Question AnswersShould TRV be on flow or return?
The vast majority of new TRV's are bidirectional and can be fitted to either the flow or return, but it is always good practice to fit them to the flow side. If a non bidirectional TRV is fitted on the return side it will create a vibrating sound as the water tries to flow though it.What is the best condensing boiler on the market?

What number should my boiler be on?
Cylinder thermostats are usually fitted on the side of your water cylinder. They have temperature scales marked; you should set them at between 60 and 65 degrees. Your boiler will usually have a dial on it, marked in numbers or from Min to Max.What temperature should I set my boiler to?
65 degreesWhat should the temperature difference be between flow and return?
Balancing is done using a differential setting: that is, the absolute temperature is unimportant; what you are setting is the difference between the flow and return. The usual setting is 11 degrees C (approx 20 degrees F). Once this is correct, you then measure the temperature drop across each radiator.What temperature should I set my Vaillant boiler?
If the boiler is heating hot water then it will need to be set at least 5-6° above the target hot water temperature which is ideally set to 55° making the boiler need to be at least 60°.How do you know if your boiler is condensing?
You could check your boiler manual for reference to condensing or 'HE' in the title. Check the flue terminal which is usually sticking out through an external wall near the boiler. If it is plastic and white steam comes out of it when the boiler is on then it is likely to be a condensing boiler.What pressure should my boiler be at when it is running?
Your boiler must have the right amount of pressure for the hot water to properly circulate around your house. For most systems, your pressure gauge needle should be between 1 and 2 bar. In this article, we'll show you what to do if your boiler's pressure is off and how to spot any pressure problems.Does a condensing boiler need a drain?
Essentially, a condensate pipe takes waste water away from the boiler. All modern condensing boilers require a condensate pipe to run to a suitable drain. It can be taken to the outside, run internally, or even pumped through a 10mm plastic tube rising vertically, then to a drain.What do you mean by condenser?
In systems involving heat transfer, a condenser is a device or unit used to condense a gaseous substance into a liquid state through cooling. Use of cooling water or surrounding air as the coolant is common in many condensers.What is the best oil boiler?
