Central heating by gravity.

[Johndell]

I want to install central heating, boiler to puffer by gravity, puffer to heater elements and hot water boiler by pump.
Anyone can helpme with drawings?
I want suggestion about this.

Thanks

What's a puffer??

Beat me too it!

yes what is a puffer and ch will only work on gravity if the rads are higher than the boiler ie they will work upstairs but not down

do you mean buffer?

 

[wnjswozo]

have a re think,it,ll cost a lot to run,on gas, by the way you wont get a gsr installer to fit it for you as its illegal to fit that type of system now

Puffer is an hot water acummulator , is acummulating the overheat from boiler. Ussual is used with gasification boilers.
Normal, we have 2 circuits: first - boiler to puffer, second - puffer to heater elements.

I guess you mean Buffer and you are outside the UK?

I would consider a thermal store system

 

[Johndell]

Sorry!
Buffer corect name, puffer is in german language.
I am not from UK, I am from Romania.
Principally I now how do this but I want an other opinion.
Thanks

Gasification boilers require to be run flat out and to have a high return temp. so a loading valve or ladomat valve is used, it sends a proportion of the flow water straight back to the boiler untill it is up to temp.

It requires to be pumped not gravity to buffer/puffer and then pumped to the heating circuits.

This is not a just requirement for the UK but to prevent the boiler condencing and then corroding.

i thought that u can not install a gravity open vent systems ,as it has to be fully pumped sealed system as per part L building regs

Part L of the building regs does not cover Romania
