- a boiler
- Piping system

- Radiators

I've heard of these but I've got no idea what to choose and hat to do..
what shall I add for better performance, and beter design???

Theoretically Speaking...

I really appreciate your help..

For expansion tanks, use a bladder type not the traditional conventional type; several manufacturers have quality offerings here. Spirovent makes a very good air eliminator. For circs, the pump curve is more important than anything else. Taco, Grundfos, B&G, Armstrong and others all make good circs.

For boilers, it really depends on the application, the design of the system and the choice of fuel.

If you want to know how to optimize your system may I suggest:
