An applicont came into the office <br /> l and inquired where he might find a water heater with an CF o(0.82, since none of the local suppliers were able ro get <br /> one for him. Are they out there antl he is just not iooking in the right place or is it truly a hard to find product. lhe <br /> reason I am asking is that there are a lot oF new plans that are showing energy credit compliance by choosing option 5b <br /> from tablc 40G.2 (BTW why isn't it Table R406.2?�. <br /> Although there are a few manufacturers that make a condensing NG storage tank <br /> type water heater most with an efficiency of 0.82 of greater are going to be <br /> tankless types. There are lots of them out there. <br /> The second question is; <br /> I have an applicant that is applying for a permit ro construct a 2700 S.F. SFR. For his [nergy Credits(Debits) he is � <br /> designating uptions 3a (0.5 credit) and 3b (1.0 credit) for a total of 1.5 credits. I tried tn explain that he could not use <br /> both option 3a & 3b for compliance on a single house. To be honest, 1 can't explain it ..� II enough to convince him that ' <br /> it would be the same as installing two separate heating systems in one house. Please let me know if my assumption is , <br /> mrrect, that he cannot use 3a & 3b in the same house. I( he can, can you explain to me how it would work havu,g two � <br /> separate heatin�systems. Or am I completely out in left field. <br /> The improvement options in Table 406.2 were developed based on the options <br /> ability to improve the efficiency of the house-f�y a specific percentage. Option 3a <br /> �J � � <br />
