Larson 2520 Rockefell^r Everett, WA. 98201 Dear Mr. Larsnn, Attached are the calcula[ed hea:ing requir_ments which you requested, together with our es[imate of probable operating cosrs. The figures are based on 20° outdocr and 70� indoor design temperaCures and a 5,500 degree day year, which �s average for this area. It should be recognized that this cost es[imate is a customer service and not a guaranteed figurP. However, our past experience, based upon meter records, has shown actual cos�s are generally very close to the calculated costs, depending on the living habits of the occupants. ff the ins[allation of electric baseboard heat is desired, we recommend che installation of low-density units ��ith wattages not exceeding 25� pe� ��neal foot in accordance with the National Electrical Manufac[urers ,lssociation Standards. For the best operation, base6oard units should be installed with oacking insula[ion to insure an airtight fit with the wall. If an electric furnace is desire�, the District recommends the ins[allation of a balanced warm air supply system wi�h dampers and a return air system which will return as close to 100� of all the furnace fan CFM outout as possible. The Distric[ further recommends that all duct work installed in non-heated spaces be adequately insulated. This would inr.lude warm air supply ducts and return air ducts in crawl spaces cr attics and �aarm and cold air plenums on the furnace installed in an unheated garage or other unheated area. We hope this information will be helpful to you; however, if we may bc of further assistance, please call us. Sincerely, l— � �. � - • i ��/r:lJ/�ii� � �� U�/IL'-� Jennifer Gugino Ener.gy Co�servation Depar.tment Nttachment
