Questions & Answers

does this qualifies for energy star rebate program?

does this qualifies for energy star rebate program?
Asked by: Rules
Although advertising on website appears water heater qualifies for a $70 rebate, it does not with Virginia Natural Gas. According to utility, the specs indicate that this unit is only 0.65 when 0.67 is required.

Does this model XG40S12DM40U0 use the electronic ignition or does it have a standing pilot light...

Does this model XG40S12DM40U0 use the electronic ignition or does it have a standing pilot light? I seeing conflicting info. The User Manual uses the word 'pilot' somewhat ambiguously but the Home Depot description indicates electronic ignition. Which is it?
Asked by: Tim
I believe it does not have a pilot light as I did not see one at the bottom. There is an electronics ignition device (white box) in the front that also adjusts temperature. I do know the unit even though is a gas unit does need 120VAC outlet to power the damper at the top which opens and closes electrically. The unit comes with a cord about 15 ft long.

Is the installation included in the price ?

Is the installation included in the price ?
Asked by: Price
{Is the cost of Installation included / reflected with this stated Price?} Sir: Everyone is supposed to assume / take for granted that each Question is a Serious One, wanting suggestions and / or an equally-serious 'REPLY.' (A) - ....INSTALLATION IS CERTAINLY NOT INCLUDED! .... fees vary most-wildly, perhaps a couple of hundred $$ in Rural Communities without Regulations / Building Codes to be met. (C) - Inner Large Urban ares can represent at time over a $1,000 per Installation, especially whenever there have been many years since that old, failed, existing DHW Heater was originally installed. (C) - Be aware that "IF" the local Building / Plumbing Codes & Regs mandate that a licensed Contractor or Plumber be utilized BUT, One goes ahead regardless -(As Reported by Others herein)- the Home Owner's Insurance Policy may be considered in jeopardy and / or VOIDED! (C) - NO, to "self-install" appropriately is NEITHER simple nor straightforward for a "First-Timer," in my experiences! - - - eli2
