Preparing , preparing , you're always preparing . OZ-T's "Just build the damn shop already build ".

In an insulated slab , yes . The thermal mass of the concrete stores heat efficiently .

Also , you need to look at the tubing as extended storage of the hot water instead of the system consuming hot water . The loop is closed so its always the same water in the system . Once the water has travelled through the tubing , it returns to the tank or boiler not as cold water but as water that is a few degrees colder than it left , so you aren't reheating cold water but "topping up" hot water by a few degrees each time the thermostat calls for heat and the water pumps through the system.

 

Do you get enough sun to add a solar pre-heater?

 

Some people were using a residential gas water heater with a grundfos pump set at 120 degF.

 

not enough to make sense

 

no natural gas in my area , propane or electric

 

Retaining wall / grade beam #2 and post columns poured and stripped





Surveyor here tomorrow for siting certificate and then we start framing finally

 

Column detail turned out great

 

thanks guy

 

Which are you using? We’ve been studying cost of propane vs electric resistance vs air source heat pump and all of our real world test houses have shown the ASHP as more efficient and lower cost than your alternatives. This is in Minnesota and we were mainly studying forced air residential units with electric resistance backups for the real cold days, but the math still applies.

 

I'm going electric

I would go air to water heat pump but up front cost is way too much for a shop . We installed one for whole home radiant on a house I built a couple years ago though

 

Big Top down

All ready to start plating tomorrow

 

Didn't think you would have permitted a shop.

Are you leaving that storage area dirt or are you going to pour a slab in there later?

I think #2 and #4 column seats are crooked

Now the fun begins.

 

Need permit for any building over 100 sqft here

Outside storage area will be clear crushed gravel for now anyway

 

Yesterday I drilled and bolted down my sill plates , today I went and selected and picked up / dropped off all my framing lumber for the walls

10's , 12's , 14's and 16's of Fir 2x6




The lumber market at least here is going nuts , prices are going crazy and availability of some material is sparse

I worked with my regular lumber supplier and pre-purchased my 2x12 rafter material and 1/2" plywood a few months back but now wish I had bought my 2x6 as well but he gave me a 'personal use' price that made it a bit more manageable and as luck would have it his current stock of Fir 2x6 is Select Structural and some MSR 2400

 

Purdy. Gonna have to fill that shop with stuff from Lee Valley!

 

I bet your crib is just as up town as your shop is going to be .

 

Dude , I gotta shed some stuff before I buy any more haha

 

Well, were are the picks of the framing?

 

He must have taken the evening off
