    Just wondered end of Terrace house new boiler fitted , standard construction , 8 rads - plumber fitted new boiler see pic.

    Going grand , getting kitchen single rad changed to a double and doing a bit of Googling in very general terms , seems to be the case 19 kw is a bit smaller than generally recommended , seems a higher kw is more common
    What do you think

    Thanks

    I’m just using different BTU CALCULATORS getting quite different results !! An apprentice plumber ( good lad) reckoned 1460. 1500 a guy who priced job thought with thermostat on rad!

    I got a mad figure altogether on the btu calculator I tried....
    Anyone any idea what output rad ( approx) this room would need.
    Kitchen - width 11 feet height 8 feet length 15.5 feet.
    Window timber double glazed - 4x4 feet
    Wooden patio doors ( double glazed) 7 ft x 5 feet
    Upstairs over it , heated bedrooms
    Brickwork think ordinary block work ( house 15 years old)
    2 outside walls ....

    Thanks lads
