    Glow worm now offer warranties up to 15 years on some boilers,


    Whereas my non condensing no combi old fashioned boiler, just had its first service in the 13 years I've owned it. It was a good 10 years old when I bought the house.

    There are two of us and a baby in a 2bed bungalow. The 2nd bedroom is pretty small. There are 5 rads in the whole house and one bathroom. My main concern is hot water flow for shower/filling bath. Should 24kw be enough or go for 28-30kw? Thanks!

    For heating hot water INSTANTLY, you want 30kW.

    For lots of condensation, and getting the most from the gas you pay for, you want a small boiler like 12kW.

    Yes, combis are schizophrenic. It's like asking an architect to build a house so a Zionist can live in the same house as a Palestinian.


    I have a bungalow, and there is a "lean-to" boiler room in the back.


    This is much safer than having a gas appliance inside the house.
    You should make it big enough for:


    A. A boiler with hot water cylinder, or


    B. one boiler and one gas water heater.


    Option B means you could have three gas appliances running simultaneously, including the cooker, so you must have the ticker 22mm gas pipe from the meter, not the old 15mm. Aka 1/2 inch, 1/4 inch.
