    Hi, new member here. I am renovating a 25’x20’ guesthouse in a wooded area next to a pond in Wisconsin. So it is a damp climate that ranges maybe from -20 to 110 degrees at the extremes. The floor of the cabin is 10” joists over a 2’ crawl space of dirt. I encapsulated the crawl space the...

    My wife and I are in the middle of renovating a 1500 sq ft ranch house in Upstate New York (Adirondack Mountains). The house currently has a forced hot air furnace with no return ducting (mobile-home style furnace). I really dislike the current heating scheme and the thought of doing all the...

    Hi all, I recently installed a Honeywell Lyric T5 thermostat for my heat-only hydronic system. I ran all new 18-3 wire (old system had 18-2 wire) so I could add a C-wire. I connected the C-wire to the C terminal on the transformer in my Weil McLain boiler. Everything appears ok until heat it...

    Hey guys, I've got a quick plumbing question for you. I've got a 1938 cape, the piping for the baseboard is 1" copper. The baseboard in the kitchen is mangled, the case is missing, large chunks of the aluminum fins are damaged. Repairing the old baseboard looks like it'd be tedious, and...

    I'm moving into a Seattle townhome built in 2005. It has a hydronic heating system with wall fan units, and separate thermostats (the simple knob kind) in each room. It seems that the thermostats control the actual fans in the wall vents, but they don't seem to turn the water pump on/off. As...

    Question: How can I wire my fan ON/OFF to be controlled by the thermostat heat call instead of using an aquastat or fan-limit switch? Background info: I have a hydro-air system with an aquastat controlling the fan for heating, thermostat controlling the fan for cooling. Problem has been that...

    I have a gas furnace with hydronic heating system using baseboard pipes on my first floor (Zone 1) and a heat exchanger in the attic (Zone 2) that is used for forced warm air throughout the entire home. Zone 1 works without issues. Zone 2 seems to be behaving strangely. Here is a typical...

    Conditions: 1. 3 zone hydronic floor heating, 3 zone pumps, 1 primary pump. Lochinvar Knight 155 mod-con. Basement slab, 1st floor and 2nd floor (extruded plates, insulated). Oversized boiler because of drive-under garage that might get additional modine heater. And global cooling on the way...

    Hi all, I've used this and other sites to get a lot of information before attempting my hydronic radiant (in-floor) installation, so I figured I'd give some back by making some information about the process, pitfalls, things that worked and didn't work, etc., available to others. I've started a...

    All, So I am in the process (still) of putting together my radiant heat system that is comprised of a primary and 3 secondary circuits. For an air separator, I purchased the Bell and Gossett IAS-1 (my primary circuit is 1") to connect to the primary and the expansion tank. The literature and...

    I have a Triangle Tube f35 oil-fired boiler (now discontinued). House is 1,200 sq/ft living and 400 sq/ft garage. Each on separate hydronic zones. There is no mixer valve installed and I have the hydronic water set at 110 degrees F. Will installing a new thermostat with a floor sensor save me...

    I'm trying to decide how best to get some heat in my 1500 sf detached garage in Wisconsin. (Best = lowest operating cost.) My goal is simply to keep the building above freezing, probably 40-45F. The PEX is already in the slab, but not hooked up yet. Natural gas is available in the garage. I've...

    I am trying to wire an 8-wire White-Rodgers Big Blue (model 1F95-1277) thermostat to accomodate 1 cooling stage and three heat stages. I want my Hydronic Water heat pump to be the first stage heat, the Hydronic Forced Air to be the second stage heat and the electric heat strips to be the third...

    Just had a new Munchkin T50M installed. My only concern is with protecting the utility room from freezing pipes. Living in Alaska it gets pretty cold and the room that the boiler and my older (separate) gas water heater live in is an outside access utility room, about 5 ft x 3 ft, and I know...
