Wood fired boilers, any comments on them. We have a customer interested in purchasing one for a radiant job we are installing with the water storage system.

    Clean burning and efficient

    Most notably the gasifiers (Solo models).

    You need a piping scheme that avoids low return temps and everyone (especially Tarm) recommends a hot water storage tank.

    And they're on sale until the end of May.

    When you get one ...

    ... I can tell you a couple of things you should NOT do (like buy the combination wood/gas, for example).

    The Tarm people are tops.

    Nicely built

    with a long track record here in the US of A.

    The piping gets pretty wild to protect the boiler return, temper for radiant,and provide an over temp dump zone.

    The 3 way thermostatics on the last one I worked on were leak prone, and I would use a better ball valve for isolation on all ports.

    Be sure you have a good purge procedure figured out. With multiple 3 ways you need some positive shut off isolation.

    I also add an air scoop on the piping up and over to the storage tank. If you pipe across the ceiling. This seems to be the spot where they trap air and lose circulation.

    The wood needs to be dry, I mean really dry to burn and gasifiy properly. Some brands sell a moisture meter with their gasification boilers.

    Don't forget combustion air! As the DIYer did on my last Tarm fixer!

    And I highly recommend a CO detector in the room. They should be standard equipment.

    I'd like to see them offer this Laddomat valve as an option. it would really clean up the piping and offer a circ, return protection, and over temp protection in one neat package.

    2nd year

    I put a Tarm Solo Plus 30 in Summer of 2005.

    Tied to existing 40+ yo lp boiler serving 3zones of HWBB and a side arm hot water heater.

    No heat storage so we stoke it 3 times a day minimum in 30 degree and below weather...Check it quite a bit more often than that.

    I clean heat exchange tubes every 3 weeks or so and check/brush the chimney twice a year.

    We've been happy with the Tarm. Dry wood is key!

    Tarm

    The Tarm Gasification Boilers are incredible, with heat storage you can't beat them.I put one in combination with drain back solar panels on a radiant job a year ago the chimney is as clean as the first day we fired it. At 20 below ther was only about 18" of mostly water vapor coming out of the chimney top.I agree with Hot Rod on the three way mixing valve it functions well but the ball valves that come with it are Mickey Mouse.

    We now offer

    an Acaso "Loading Unit" that provides the same funtion as the Ladermat. I have been using one for the past 5 months and it works really great. It has the thermostatic function for boiler protection, includes a three speed Grunfos circ and has thermometers on all three ports. Easy to install and it will work well every time.

    Tarm wood boilers

    are really great. Jerry put in several of them with lots of combinations of ways. Oil backup in old farmhouse with radiant in a new mother-in-law apt. Really well built and work great. ...Ruthe
