• What are the advantages to this, over just having a suitably powerful combi boiler?

    I’m scratching my head trying to convince myself that a ~40KW combi will suffice for our new family bathroom, downstairs toilet and 35m2 wet underfloor heating…

    Combis tend to be put in the dumbest place in the house. So even if it can meet multiple demands the placement will not flatter it. Unventeds less so.

  • Placement isn’t an issue for us, as the whole back of the house is getting ripped out and re-vajazzled.

    Just trying to work out why so many people swear by system boilers, when to my lay mind a suitably-sized combi would just give us unlimited hot water on demand without any tanks or timers…
