So if I used the charts attached .. If the 62.7kw (214000btu) Im trying to get to would equal approx 2.00usg at 100psi would be the same as using a 1.65 nozzle at 145psi?

Ive estimated the previous output was about about 61Kw using 1.95 usg/hr. If Adjusting the diffuser to fine tune the settings what should I be expecting if I adjust it up and down.

I have found a Boulters boilers commissioning data sheet, that lists most of the boulters boilers. Shows Models, KW, Head, nozzles, PSI, bar CO2 and flue temps. It also has data for class D gas oil.. It looks like the data I have to set it to is similar to that of the 51kw Class D gas oil...

The flue gas temp is measured outside at the flue. It is a short run, 90deg out the top and straight through the wall . About 1mtr from top of boiler to test hole in the center of the flue. Balanced Flue

Do you think the flue temp is unusually lower even with it only being 0.1 size off the lowest nozzle and with higher oil pressure. , If I change the nozzle to the 1.35 output, Should I also be looking for some another fault. ?

I asked for some extra info from them to follow but have not heard back, so quite happy actually not to be the 4th plumber in a year. But good to learn on others design opinions. Would be more interested on how the tapstat / bypass from Johntheo5 set up works as I have a client grant boiler on...

I did ask for the ASHP install design details but was told they had nothing ...

Hi. I have a potential client that has all the radiators fitted suitable for an ASHP (but pump not plumbed in) now they want an oil boiler plumbed back in instead but want to keep all the big radiators , just in case they decide to change their mind As they still have the ASHP but not fitted. ...

I know a while back. but Im having the same dilema (44kw Boiler) . Did you find sort the issue? Did you find a blending valve for 50kw boiler. Or did the bypass with manual valve work?
