Unvented cylinder in cellar

[leelister6]

Hi all. Just been to look at a job and customer wants the boiler relocating to the cellar. He wants an unvented cylinder (I'm G3) also in the cellar, the only problem would be D2. Obviously can't discharge uphill so what are the alternatives?

Property has 1 bath, 2 mixer showers, 3 basins and kitchen sink.

Dont like the idea of putting a tank and pump in the cellar if that's even possible as if the pump were to fail and no-one notices, they'll have a nice underground pool.

He's mentioned a WB Highflow combi but would that give sufficient flow with all outlets open?

Pump house do one for unvented cylinders

On some you add a remote alarm for high water level and some can be wired to cut the boiler out.

Pump definitely, the only way mate

As above pump is the only way .kop

Thanks chaps. Have emailed Pumphouse for a price but think I might recommend a high flow combi

They are not cheap bud even if you fit a high flow you will still need to get the condense and PRV to discharge to a safe place ? So it either one of these ouch ! Kop

Is there a soil stack down there?

Thought highflos have a built in condensate pump? Yeah still got a prv problem tho.

Correct but it's the only one I know rated for an unvented cylinder
