hi can someone please tell me whats the best kind of combination boiler to get for reliability and most powerful thanks
baxi duo tec says so in which magazine......
I agree.The truly economical appliances have an outside temperature sensor wired back to the boiler.
This enables the boiler to vary the temperature the Radiators get to when the heatings on.
With the sensor fitted your rads will not get very hot on days like today where the temperature outside was around the 12 degree mark, but those same rads will get hotter once the sun goes down and the outside air temp is colder.
My first reaction on reading that was to think that it was rubbish, then it dawned on me that you were talking about the increased output due to the boiler condensing.When the boiler runs at lower flow temperatures it get more heat out of every £1 you spend on gas.
I asked one installer what he thought of weather compensation. His reply: "What's that? Is it like a frost stat?"The trade name for this energy saving outside sensor thing is "Weather Compensation". Make sure your installer knows what it is.
