Re: Multiple detached garage questions

here's some examples ; http://www.hotwater.com/products/residential/gas.html

Try laying out the size of the enclosed space with tape or 2X4's and see what impact there may be.

Maybe its me, but a tankless water heater sounds like it might be a consideration in your situation. Then you wouldn't have to insulate around it. (or even better you could cram it into a spot in the house that a normal water heater wouldn't fit.) Its a more expensive option initially but I love mine.

As to venting the roof without a soffit, take a look at vented drip edge. Air Vent makes one.

If you're using an on-demand water heater for individual sink locations throughout the house then you're fairly alright in terms of expense. However, if you're thinking a whole house in-line water heater then this may not be a money saving option.

Our local power company provides this statement:

The positive side

  • The efficiency of some in-line water heaters is 99%
  • Water is heated only when needed, which results in an estimated 6% energy savings over tank type heaters.

The negative side

  • The size of a tankless water heater needed to raise the incoming water temperature from 50F to the outgoing water temperature to 120F
  • At 1.5 GPM (enough for one point of use at a time) would require 70 Amps and 2-50 Amp circuit breakers, the wattage is 14.4 kW which is the equivalent of operating 3.2 standard electric full-size water heaters at the same time.
  • Cost for this size of heater is $500.00
  • The estimated cost to operate an electric in-line water heater is $18.00 per month (our kWh cost is .049 cents)
  • At 3 GPM (enough foR two points of use simultaneously) would require 150 Amps and 3-60 amp circuit breakers and the wattage usage is 36kW which is the equivalent of operating 8 full size water heaters at the same time.

At this stage most, if not all, power companies would place you on what is called a "demand meter". You're now required to pay demand charges in addition to electric usage charges.

I recommend talking with your local power company for information on whole house in-line water heaters.
