HELP ??!?? Idaho Code on Residential Water Heaters is unatainable. Main Owner Builder Log

So basically we are going to have to pull our the efficient water heater that we were so happy with and special order this obscenely huge, energy hogging behemoth of a water heater for our 2 person average household in order to be in accordance with the Idaho plumbing code (Chapter 5 part I). HELP!!! If anyone can shed some light on this situation please let me know. I am at a real road block.

HELP ??!?? Idaho Code on Residential Water Heaters is unatainable.

 

We had our final plumbing inspection the other day and our brand new Whirlpool water heater had a big ugly failed tag on it because it did not have a high enough first hour recovery rating.

 

I purchased all of my appliances at lowes and I had done extensive research on water heaters and energy efficiency in order to get the most appropriate. We selected a 40 gallon Whirlpool electric water heater with an Energy Smart Control. We picked this size based on the manufacturers recommendations based on 2 high volume users  (its just me, my husband…the dog isn’t a big hot water user) and we choose the energy Smart model as recommended by the Lowes sales rep because of its energy factor or .92. I was confident that I had done the appropriate due diligence and we were very happy with our purchase…

 

So 3 months later we have the plumbing inspection and find our water heater does not meet the Gallons per hour recovery requirement code for Idaho which is 67 gallons for a 3 bedroom / 2.5 bath. So I contacted lowes and the manufacturer and neither of them had heard of a code specific to the recovery rating. In fact the manufacturer (US Craftmaster, the larges manufacturer in the US) does not make a residential model that even comes close to that rating; the highest residential model is rated at 25.3 gallons. The only one they make that meets that recovery rating is a commercial 70 gallon unit that has a recovery rate of 71 gallons!

 

So basically we are going to have to pull our the efficient water heater that we were so happy with and special order this obscenely huge, energy hogging behemoth of a water heater for our 2 person average household in order to be in accordance with the Idaho plumbing code (Chapter 5 part I).

 

HELP!!! If anyone can shed some light on this situation please let me know. I am at a real road block.

you might try calling the code official and meeting him to talk about the code requirement, sometimes it is the interpetation of the code that is the issue and sometimes it can be talked through and allowances made or maybe different solutions. I am not familiar with the plumbing code, but I would think it would depend on fixutures in the home and the volume and flow rates as well. it is written so someone does not install a 40 gallon water heater in a home where they also install huge soaker tubs and like, so I think there would be allowances if your water heater can supply the flow rates and fixtures. hope that helps?
