HPWH Performance Report 4. Installation Time and Cost Summary As seen in Table 10 and Table 11, the average installation costs for the Sanden units were $8,588 while the Rheem units were $4,135 19. When compared to a similarly sized standard electric water heater we estimate the incremental cost of the Sanden unit to be $5,955 and $1,558 for the Rheem unit20. The largest portion of the total installation costs was the cost of the appliance. The Sanden installations include significantly more electrical and plumbing complexity and costs due to the split system design as well as freeze protection and electrical permit costs. The Rheem installations on the other hand costs also include full ducting for bringing in and exhausting outside air which is not required for operation but eliminates interactive effects with the heating systems. The average Sanden installation required 21.3 hours of skilled labor while the Rheem units required 10.5 hours (see Table 12 for breakdown). All installation costs are in Canadian dollars and labor costs are based on typical skilled labor rates. Energy 350 installed materials such as ductwork and pipe insulation in parallel with their performance monitoring equipment. All monitoring equipment costs and associate labor are excluded from the costs shown below. The plumber labor hours are reduced by 25% to account for the time spent plumbing to Energy 350’s performance monitoring equipment which will not be a part of standard installations for either the Sanden or Rheem water heating systems. As the installation of both Sanden and Rheem HPWH systems become more familiar to contactors, the installation costs associated to the labor hours is expected to decrease.
