Butch - The RANCO two stage thermostat will allow you to program the the draft door and the fan the way you want. I have been running my Hardy H2 just as you described for the past 6 years and tracking the water temperature, damper position and fan status with a data logging program, just...

I have my data logging program running in the back ground of my main PC, and the reasoning for the two stage control was to minimize the exhaust stack temperature. I played around with lowering the water temperature set points until the stove went out a couple of times during the day under low...

I've been doing something similar using a RANCO two stage temperature controller with my Hardy H2. Basic operation: Damper solenoid opens at 160F, closes when the water temp gets above 170F Fan comes on if the water temperature falls below 150F, turns off at 160F. The RANCO has a...

The top is held down on the edges with self drilling stainless screws. The center hole at the smoke stack sits on a flange that has a heavy bead of RTV on it. If you plan on taking the top off you will need to have some new screws on hand, I seem to always break one or two in the process of...

Our operation pretty much requires 3 people - A "loader" to get the slabs to the table, an "operator" who positions the slab for cutting and operates the table and an "off bearer" that takes the cut slabs and either stacks them or loads them on the trailer. We normally cut to ~ 25" lengths to...

Seeing if I can imbed the images:

Here are some pictures of an engine driven buzz saw that we use. Guessing it is at least 75 + years old, was made by the Buller Manufacturing Company in Hillsboro, KS and was originally belt powered. The construction is mainly bolted adn it you want more pictures / dimensions let me know. FIL...

Scott is right, 18 degrees is low for a temperature drop across the hot water coil. You might want to check to see if the coil is undersized for your house heat load. The standard TACO pump on a Hardy H2 is good for a nomimal flow of ~ 5 gpm which combined with your 18 degree temperature...

If you want to add a coil inside the stack it needs to be Stainless, copper won't stand up very long inside the stack. Also you will have potential to plug the stack with creosote when you cool the temperature down. I also had thought of ways to reduce the stack temperature and have had...

Another place that can hurt the overall system performance is in the selection of underground piping. Invest in the best insulated piping system you can afford, no sense in wasting a lot wood heating the ground. There are several good insulated pipe systems available, IIRC they were around...

The oil furnace was propably sized with some safety factor. (Hopefully it does not run 24x7) Your system will be limited by the weakest (smallest) link. Bear with me on the numbers and feel free to PM me if you need clarification: If you have the standard Taco 009 pump on the H4 the...

The choice of pipe size should be based on the length of pipe, elevation difference, heat exchanger size and pump size. Going too big does not hurt other than on initial purchase cost, if you go to small you may severely limit the amount of heat that can be moved from your stove to the house...

The stainless steel in a H4 is probably worth $500.00 at the local scrap yard not counting the pumps and other stuff. Only issue to worry about is if the water used to fill it had a high chlorine content which can cause Stress Corrosion Cracks at the welds over time. (look for very fine...

Just wanted to drop a note to SP and LP for the hospitality, hate we had to leave before all the saws got to running. Hope we can make it again the next time.

Fired mine up on Saturday with some dead limbs that had fallen during the summer, will probably fire it every 3 or 4 days for hot water until we need heat.

I plan on being there, provide the weather cooperates.

Add a Snap-Disc thermostat inline in the low voltage circuit that operates your OWB circulator pump. This type of thermostat stays closed as long as your water temperature is above ~100F, when the water temperature drops the thermostat opens and keeps the pump from coming on. The thermostat...

As the owner of an 039 (I picked it up at an estate auction for $120.00), I can say that the 029/039 series are decent saws for general all around use. I do a fair amount of cutting so I tend to keep a mix of saws on hand and try to match the saw to the task, but if you could only have one saw...

Be safe, NOAA had Danielle headed straight to NC in the earlier maps, hope she turns east and goes further out to sea.

A Thomasville (NC) man died of injuries from being accidentally electrocuted while clearing a tree in Burlington on Wednesday afternoon. According to H.G. Coble, a retired officer with the Burlington Police Department, William Ricky Phillips Jr., 35, of 212 Washboard Road, lot 1...
