HELP !! Baxi Bermuda Inset 2 Back Boiler 50/4

Does it matter much if the ch pump is on the flow side or return side if its sending the water in the right direction

Honest

Surely there is some disadvantage because the flow chart only shows it as a pump in the flow pipe.

Technically it doesn't matter, however the boiler in question had to be connected the right way to suit the type of system.

It would be a good idea to say what you had in mind and why you ask.

I was wooried that the injector tee that links the hw return and ch return might be influencent by having the pump so near it, do you understand, cause it shows on diagram that it should be on the flow !

 

[doitall]

A positive pressure is always better then a negative one, and it's easier to connect the open vent/cold feed if the pump is on the flow, and reduces the chance of any problems

I'm a low life laundry engineer, will it still work ok ? Primatic cylinder, single header tank ?

 

[doitall]

If you have a primatic cylinder then the pump wants to be on the heating flow.

Currently its on a glowworm 4 port boiler, with pump on return. What problem would I create by leaving pump where it is on the 3 port injector tee baxi. Sorry for being a pain mate !

 

[johngodea]

Please pal

 

[doitall]

By having the pump on the return you are putting the maximum pressure on the primary flow. Not a good idea with an primatic cylinder as you could loose the bubble

 

[johngodea]

Could lose the bubble ???

 

[doitall]

Yep the bubble in the primatic cylinder that keeps the secondary water seperate from the heating water
