Any ATAG specialists in Bedford area?

Hi

I recently had an IC Economiser Combi 35 installed with piping upgraded from 15mm to 22mm. A different engineer (ie not the one who installed it) came out today to address a pump overrun issue and, in addition to flagging up a couple of settings which were still on factory default and a slight kink in the piping, pointed out that the pipe diameter is too small resulting in not enough pressure - it should be 28mm.

The run is approx 6.5m, with 7 90-deg elbow fittings, and 1 t-junction which also serves the gas fire. I've input these details into the Baxi Toolbelt app and and it appears to be adequate - it shows only a 0.65 mb drop in pressure. That said, I may be missing something obvious here. I've since spoken to the bloke who came this morning, and unfortunately he can't remember the details he used.

I'd like to get a 2nd, independant opinion. Can anyone recommend an ATAG engineer in the Bedford area please?

Thanks

Did you include the KW rating for the gas fire and the HW rating for the boiler probably exceeds 35KW. I suspect the 2nd plumber is correct.

No - I only used the boiler spec. Thanks for confirming, though I'll still be looking to get someone else in to eyeball it and confirm who's correct. Was hoping to get a recommendation from here... Google it is then!

The DHW input for your boiler is 40.3 KW and the effective pipe run is 10m, if your gas fire is rated over 5kw that pushes it over the allowable pressure drop using your app.
