My own house

2P/RR systems. Whenever is was practical, I designed around it.

Tiny (relatively speaking) pipe sizes, ultimate room by room control possibilities, and just a treat to mess with.

Whether PEX, C or S pipe. 2P/RR is king IMO!

    my own house

    I just bought a house. It's a two family house. Needs two new kitchens, two new baths, two new heating systems. it currently has one oil FHW boiler for the whole house all CI radiatos which I am keeping. I am getting two boilers from the gas company whatever they give me. Probably Burnham revolutions. I was going to seperate it by running pex home runs to each radiator. But Then I thought it would be kind of cool to do a reverse return system in blk pipe with all cast iron fittings and thread all the pipe. i don't mind the labor but do you guys think it would be a total waste of time? I think it would be kind of cool but a lot of work. I don't mind because I will be ther a while. What do you guys think?

    i have been taking some time off lately....

    and getting some rest...


    i need to go see the folks...could you use a hand?

    all i could pack "with" would be a few wrenches ,a few drill bits maybe a few test instruments thats about it... if you like the pex idea i could lose the 4' wrench in favor of a pex tool or two... belive me , a two family home would be a vacation for me....

    pex

    I would do pex with manifolds, then possibly reverse return, depending on how I was piping. I would definitely do out door reset.

    PEX it...

    the steel/copper sounds really neat...ut let's be realaistic about this. steel and copper are a lot more $$$ thatn pex. and the other even more precious part is your time. It will take you alot of time to do the reverse return loop twice. From the sound of it you have a lot of work ahead of you w/ other projects...do the home runs w/ the manifolds. That is what is have in my house w/ panel rads.kpc

    The gas company

    probably won't give you Revolutions. Not only do they cost more but they're more efficient so they won't be able to sell you as much gas. If they do give you Burnhams, it'll probably be the Series 2.

    Given the recent behavior of gas and electric utilities, I'd carefully look their "gift horse" in the mouth, as the old saying goes. Once you're tied into their unregulated monopoly with boilers that can't be changed to another fuel, you're screwed. They then dictate what you pay for fuel, raising rates whenever they want.

    If that were my house, I'd install boilers that could be fired with gas or oil by swapping the burner. The Solaia and Smith 8 series boilers are offered with either fuel from the factory. That would put you in the driver's seat. If the gas company got too greedy, you could switch without buying new boilers.

    I like the reverse-return idea, but am not sure it would offer better performance than home-run PEX. The PEX manifolds in the boiler room have the additional advantage that you can lock the boiler room so tenants can't tamper with them.
