Barn conversion - new CH system

[Giblett]

Hey all,

Few things: Barn is up a small hill, with the mains a good 500m away.

Tried to measure the water pressure at the tap we currently have, and the pressure gauge kept popping off, despite tightening the circlip as much as possible.

Anyway - it seemed to give a pressure of ~3bar (didn't seem right); so another test we tried was turning it on, and then turning a lot else on to see if the flow rate dropped, which it did not (noticeably).

The system that is being proposed is a Glo-worm ultracom 30sxi (believe it's a condensing one), with a 210l unvented cylinder. The property is a 2-bed place, and will be a holiday let. Has a downstairs shower, upstairs bath (maybe an electric shower, maybe one on the system upstairs, can't remember at the moment!). Energy will be provided by LPG gas bottles (not on the main), with a backup immersion in the tank.

I think I read elsewhere, that the minimum flow rate is around 20 l/min - I haven't measured this yet, but will do so tomorrow.

If it's any lower, will this boiler still be any good? I don't really understand what it is that I will be buying, which makes me nervous

Cheers.

Sounds fine to me.
If you are getting a flow of 20 litres a minute no problems.

I would go for a ultra power. Unvented and cylinder all in the nice one box. Job done and much faster to install.

Combi boiler would be the cheaper option since it is only a holiday let.
With electric shower as backup should the boiler fail.
