Energy audit

@ September 1, 2014 7:25 AM in Hot water radiators in place of steam system or hvac

Find someone or a co. that does energy audits. They can do a "blower-door test" and find where your house has signif. and lesser air-leaks. These are the first things to fix, and then improve your insulation. The same co. should also have an infrared camera, for finding poorly insulated areas of your house.

Taking the bait

You just said"forced hot-air" because you really know how bad a choice that is, and that a whole lot of the Wallies will jump all-over that bad idea--and chime-in with plenty of good ideas. Right?

solar system glycol use

Great summary Mark. Some invaluable nuggets in there. Can we put this in the "Solar" section?

To rick of Alaska: I humbly beg to differ. One of the best "tools" I have ever acquired in my career is "Ockham's Razor," compliments of William of Ockham, a 14th cent. English philosopher/logician. Its a logically elegant principle of problem solving. Basically: start with the simplest fix, FIRST. E.g.: If your car stops running--check the gas gauge.
I use the "Razor" almost every day.

a "certain radiant design co"

@ March 9, 2014 11:46 AM in Is this fixable?

Just a heads up: I live and work in VT. This drawing format is recognizable as being from a "certain radiant floor design co. in VT" that caters to DIYers. Also notice that it does not say "boiler" in the diag., rather it is labelled "water heater." Lucky, at least it is labelled "closed system."

A masonry bond directly to plywood is not recommended. Especially one that changes significantly, thermally. You might consider several products made by this German company. They make excellent products for improving the bond between plywood sub-floors and masonry or ceramic finished floors. These products add some minimal thickness to the final floor. Not sure how they interface with pex, i.e. fastening pex down through the membrane.

got it

I understand now. No need to blow out a seasonal system if you set it up right. Just open some valves and drain it down. My systems do solar DHW in spring, summer, fall and wood heat does DHW in winter. These are open loops with potable water. No glycol.
Homeowner must sign off on being vigilent about WHEN to switch over the systems.

Seasonal solar systems

I have done all the above except have not had any systems "blow out" in the winter.

More respect is due

Sir,
I would remind you that a whole lot of contractors post on here, often with very helpful and free information to the general public. Your efforts to acquire information would be more successful if you eliminated self-defeating comments about contractors.
