Just been adding up the BTU's for the rads I need to fit a CH system into a 3-bed terraced house. The total is approx 40,000 BTU's.
I asked about boiler choice on here some time ago and was recommended a Vokera. Thanks to all that advised on that.
The retailer has 3 available - all Syntesi condensing SEDBUK A rated.
25e (80,000 BTU),
29e (100,000 BTU)
35 (120,000 BTU)
Hot water requirements will be washing, showering, baths, washing up etc.
The question is which boiler output will be most suitable? I have assumed that the highest output will be best (partly due to the endhanced HW flow rate). Do I need this high power output? And will 22mm pipework carry the heat away from the boiler sufficiently quickly to be efficient?
Thanks for any advice
