Electrical Efficiency for Gas Furnaces.

I've noticed my new furnace uses about the same electrical power to operate as my old furnace, even though the new furnace (44k) is 1/2 the BTU of he old one (88k). Both furnaces use 1/3HP 5amp…Continue

Tankless Water Heaters... has thier time finally come?

For decades tankless water heaters haven't been worth the effort to install due to our artificially low cost of natural gas in the USA and the high price of tankless heaters. Tankless water heaters have dropped to under $1,000 while tank water heater prices have continued to climb. Are tankless water heaters worth rethinking?I have found 3 basic types of tankless water heaters:1: Non-modulating with battery powered igniter such as they use in Europe. These can be bought in the US for under…See More

"The first thing that could be done is get rid of those recirculating range hoods that 90% of new homes use. Require all range hoods to be vented to the OUTSIDE."

"Once ductwork is considered a minisplit may actually be cheaper. It provides cooling also. With a -15f temp the mini split ain’t gonna work."

"ECM could be the way to go. At $250 it does have a long payback though. The use of a 1.8A Shaded Pole inducer motor seems wasteful, a PSC would use 1/2 the power to do the same job."

"I replaced my own 80% with a 90% furnace last fall, made no noticeable difference in the gas bill. The payback time for going from 80% to 90% just isn't there unless you can buy the 90% for cheap."

Replaced my A/C this weekend, results of downsizing by 1/3.

Recently my 13 yr old Carrier A/C devolved a leak and I chose to replace the system rather than track down the leak and repair the coil. I had been reading about doing manual J calculations and how contractors are scared to death to undersize. I had been talking to co-workers about this and it's an uphill battle getting them to think different than 1 ton per 500sq ft. So I decided to take confidence in correct sizing and "put my money where my mouth is" and install a 2 ton sized…

How SmartHours Plus works: It costs more for electricity during peak periods of high customer demand.

Other factors, like weather conditions and the time of year, also drive electrical prices higher. SmartHours Plus,

sometimes known as Variable Peak Pricing (VPP), allows you to save when costs are lower, or off peak. Peak hours

are 2 to 7 p.m. weekdays, and prices during those hours vary based on demand (see chart). You’ll get advance

notice of tomorrow’s peak price the…
