    Default Hydronic Baseboard Heating System

    I am building a log home in N. Arizona. We are located Off-Grid. Our county requires thermostatic controlled heat in every room. I have purchased Slant/Fin Baseline 2000 Baseboard heating units for each room. I will not be using this system much as I have installed soapstone fireplaces. I am looking to use a Tagaki Tankless water heater instead of a boiler as well as Thermapex for piping. I am struggling with the rest of the components. Manifolds, zone valves, thermastats, circulating pumps. Can anyone help me with the layout keeping in mind we are very remote, using propane, and solar for energy.

    Thank you ever so much for any feed back!!!

    hartcole,

    I would hold off buying any further components or parts until you have a solid fix on exactly how your hydronic system will be constituted.

    There are numerous permutations of the basic idea of hot water heat; they all work, but the components can be very confusing.

    There are on-line companies that sell assembled "kits" that include the water heater, and all the other components you mentioned; these come along with a set of instructions and an installation manual.

    For example, the water heater can be a tankless heater, a propane hw heater, a boiler, or (in your case, if you live in a warm climate) solar panels you put on the roof.

    All of these systems work, but the components are often confusing and expensive mistakes can be made if you are not familiar with installation.

    You will also find on-line, diagrams of how systems are assembled; many of the installation manuals (below) from these companies are free of charge, with no obligation to buy when you order the free manual.

    I'm not saying you should BUY any one of these kits, but STUDYING THE COMPONENTS will clarify in your mind what has to be done.

    Most of these systems don't use baseboard elements, since baseboard is designed to work at ~180 degrees F, wheras sub-floor radiant using PEX is designed to operate at more reachable temps of ~120 degrees F.

    Plastic PEX is low-cost and is run under almost every square inch of the floor as the heat distribution system.

    These are known as "radiant floor heating".

    Google this phrase, along with "hot water heating systems", to get a slew of sites that provide info on this topic.

    Slant/Fin has an 800 number you can call to get info on hydronic heating systems by one of their technical staff; click onto "technical service" at the site.

    You should also consult the local Yellow Pages in your area under "Heating Contractors" to visit several of these companies to "see what they're doing locally in installing hydronic/radiant heat"; ask them for diagrams of their systems in case you decide to do it yourself.

    Continue in the "research stage" of this project until you formulate in your mind EXACTLY what type of system will work for you with available funds.

    I also question that the local ordinance requries a t-stat in each room, I've never heard of this before.
