Given the vast information available here... I'm having trouble answering my questions (though I'm learning a lot)

Background:  Just purchased a Central Boiler e-Classic 1450... installing 140' of 1" thermopex underground through my basement this weekend.  I live in an old, poorly insulated house with large radiators (currently hooked to an oil furnace).  I plan on installing two zones of radiant heating in the near future. 

My Plan:  Purchase a heat exchanger, connect my existing heat pipes to the heat exchanger and leave four tees (with valves) for two future radiant zones.

My Questions:

-What size/brand of pumps/circulators should I get ? (Or how should I determine this)
-What size/brand heat exchanger should I get?
-Do I need any valves (i.e. check valves, thermostatic valves) in addition to regular valves for maintenance?
-Is there a better way to heat my house than what I plan on doing?

I know this is a lot of questions/info, but there's a ton of conflicting info across the internet and I'd like some input to what's good and what I should avoid. 

Any insight would be greatly appreciated!

Thanks,

To start off with ur stove requires a thermostatic valve and it should come with one, without it you have no warranty.

did you already purchase the thermopex?  Did ur dealer offer logstor?  If he did id be jumping up and down to have the logstor instead of thermopex

I will second the logstor advice. Just installed it and it works wonderful, very rugged stuff, very well made.
