The critical tests for evaluating the ductwork in a home to determine what, if any, duct + repairs or upgrades are needed so that the upgrade to a heat pump yields the expected + efficiency benefits. + 2. The home’s heating and cooling loads. + 3. The heat pump equipment selection. + 4. The heat pump installation. + + A successful central ducted split heat pump installation starts with well-sealed, insulated, and + correctly sized ductwork, and careful equipment planning and selection. Proper installation and + commissioning are paramount to ensuring maximum equipment efficiency and a long troublefree equipment life. + The photo requirements in this document record the key steps to ensure + success. It is strongly recommended a printed copy of this report be attached to the air handler + as a record to help future home energy raters and HVAC techs. + + ## About Atmospherically Vented Water Heaters + If there there are atmospherically vented appliances inside the home after the heat pump installation, a combustion safety + test should have been performed to test for backdrafting. Please refer to the combustion safety documentation report if such a test was performed at this house. + + ## Acronyms + ODU – Outdoor Unit
+ IDU – Outdoor Unit + + ## ATTENTION CUSTOMER: Heat Pump Cleaning and Maintenance + ## Quarterly + ### Air Filter + Check the air filter quarterly and replace as needed. If your system was designed to take a 1" thick + pleated filter, they will get dirty and need to be replaced sooner than if the system was designed to + take a 4" filter. Ask your HVAC installer what filter MERV (minimum efficiency reporting value) rating + your heat pump was designed to take and purchase replacement filters of the same MERV value. Going with a + higher MERV rating can result in many unintended consequences including reduced air flow that results in + comfort problems and higher energy use. + + ## Twice a Year + ### Outdoor Unit Condenser Coil + It is a best practice to inspect the outdoor unit at least twice a year for debris build up on the + condenser coil. Leaves, pollen, and fluff from cottonwood trees can build up and block the movement of air + through the condenser coil and cause poor performance. You can carefully clean loose debris off the + condenser coil using a vacuum cleaner and a soft brush. Take care to not bend the fins on the condenser + coil. For more stubborn or stickier dust, it is best practice to call an HVAC service tech. They will + spray down your coil with the correct cleaning detergent to not damage the material and disassemble the + outdoor unit enough to spray water from the inside to push out the dust and debris and rinse the coil + free of the cleaning detergent. + + ### Supply Vents + It is a best practice to vacuum the supply grilles twice a year. If the supply grilles are located on + the floor it is best practice to remove the supply grill and use the vacuum’s crevice tool to vacuum + the area of the supply duct that can be reached. + + ## Yearly + ### Condensate Drain + It is a best practice to inspect the end of the condensate drain yearly. If there is a buildup of + goo/slime/mucus/snot at the end of the condensate drain line, it is time to call a HVAC service tech. + They will use the combination of a shop vac, drain snakes, and pressurized water to clean out the + condensate drain line. + + + ## Pre-Upgrade Tests + + + Photo of existing ductwork condition + + { + props.data.comment_ductwork + ?

Make sure every household member knows to check + the mode of both the thermostat of the central system and the ductless heat pump remote + when changing from heating to cooling or vice versa. The same applies to muti-split heat pumps + (one outdoor unit serving multiple indoor units), make sure to not set one indoor unit to + heating mode while the others are in cooling mode. + + ## Do not set Ductless Heat Pumps to Auto Mode + Do not set ductless heat pumps to auto mode which will result in the equipment making + frequent switches between heating mode and cooling mode resulting in large energy efficiency + penalties and high energy bills. + + ## Acronyms + ODU – Outdoor Unit
+ IDU – Indoor Unit + + ## ATTENTION CUSTOMER: Ductless Heat Pump Cleaning and Maintenance + ## Quarterly + ### Air Filter + Ductless heat pumps have mesh filters that need to be checked and cleaned quarterly. Refer to the owner’s + manual for details on how to do this on your specific unit. The mesh filters can be cleaned using a vacuum. + For stickier dust, wash them gently using soap and water. + + ## Twice a Year + ### Outdoor Unit Condenser Coil + It is a best practice to inspect the outdoor unit at least twice a year for debris build up on the + condenser coil. Leaves, pollen, and fluff from cottonwood trees can build up and block the movement of air + through the condenser coil and cause poor performance. You can carefully clean loose debris off the + condenser coil using a vacuum cleaner and a soft brush. Take care to not bend the fins on the condenser + coil. For more stubborn or stickier dust, it is best practice to call an HVAC service tech. + They will spray down your coil with the correct cleaning detergent to not damage the material and + disassemble the outdoor unit enough to spray water from the inside to push out the dust and debris and + rinse the coil free of the cleaning detergent. + + ## Yearly + ### Deep Cleaning + It is good practice to do a deep cleaning of the ductless heat pump indoor unit yearly. A deep + cleaning is not a DIY task, it is a call and have an HVAC service tech do it task. You can check to + see if a cleaning is needed by turning off the ductless heat pump, then gently pulling the louver open + and looking at the blower wheel. If there is a buildup of dust or mold on the blower wheel it is time for + a deep cleaning. The HVAC service tech will disassemble the ductless heat pump head to remove the blower + wheel to thoroughly clean it outside. When the ductless heat pump head is disassembled, they will also + clean the coil, condensate tray, and condensate drain. You can expect this deep cleaning procedure to + take several hours. + + ### Condensate Drain + It is a best practice to inspect the end of the condensate drain yearly. If there is a buildup of + goo/slime/mucus/snot at the end of the condensate drain line, it is time to call a HVAC service tech. + They will use the combination of a shop vac, drain snakes, and pressurized water to clean out the + condensate drain line. + + + + ## Pre-Installation + + Photo of the proposed heat pump outdoor unit (ODU) installation location + + { + props.data.comment_odu_install_location + ?

Pressurizing or depressurizing a zone could result + in pulling air containing moisture into walls or rim/band joists where the air reaches + dewpoint and condenses to cause water damage or mold problems. Depressurizing a zone + could also cause a naturally drafted combustion appliance in the same zone to fail to + draft properly. + + Also be mindful about the humidity levels of the space the HPWH is located in. For example, + if the exhaust air stream is directed against a wall or window on a hot and humid day, + the cool air could possibly lower the temperature of the surface to the point of dewpoint + and cause moisture damage. + + + + + ## HPWH Installation + + + + + - Check the water pressure to the house, and ensure it is between 45 and 80 psi. + If it is above 80 PSI, a whole house water pressure reducing/regulating valve should + be installed to protect the water heater and water fixture valves in the house. + - Check that the floor can support the weight of the HPWH when filled with water. + This is especially important if the HPWH selected has a larger storage capacity than + the original one. + + | Capcity (gal)| Filled Weight (lbs) | + | --- | --- | + | 50 | 573 | + | 66 | 796 | + | 80 | 921 | + + - Install the HPWH into a drain pan to protect the surrounding location from water + damage if a leak occurs. Install the leak detection sensor into the drain pan if the + HPWH includes one. + - Rotate the HPWH during installation so that the exhaust does not face a solid wall. + The exhaust of the HPWH must be more than the HPWH manufacturer’s minimum required + distance from a solid wall, usually 7 inches. If installing into a closet with a + louvered door or high and low air grill, there is a maximum distance, typically around + 12 inches, between the exhaust and the louvers, refer to the manufacturer’s specific + instructions. The louvers on the door must extend to the bottom of the door to allow + the cold air to fall out. + - Replace the thermal expansion tank when replacing the water heater, expansion tanks + typically last 5 to 10 years. Adjust the pre-charge pressure of the thermal expansion + tank to match the home’s water pressure using a tire pump. This 2009 Watts Water video + shows how to do this step. Write down the pre-charge pressure onto the tank. A thermal + expansion tank is not needed if the water heater is connected to a well pressure tank + and there are no check valves to prevent backflow. + - Follow local code requirements on dielectric unions and anti-siphon vacuum relief + valve requirements. Flexible supply lines made of corrugated copper, corrugated + stainless steel, and braided stainless steel often have dielectric sleeves in the + design. + - External heat traps are not if the HPWH has a built-in heat trap. To determine the + presence of in-built heat traps, look at the cold water inlet and hot water outlet for + plastic or metal hardware that captures a ball or rubber flap as shown in the examples + below. + +
+ + - Do not make any soldered inlet and outlet connections while connected to the water + heater, the built-in heat traps are plastic + - Insulate the first 5 ft of hot water pipe to R-3 or more. If a recirculation pump is + installed insulate all hot water and recirculation piping. Some HPWH rebates may + require the recirculation pump to operate on a timer or demand button to reduce standby + energy loss penalties. + - The pressure relief valve discharge must terminate no more than 6 inches above the + floor surface to a waste receptor or floor drain to prevent hot water discharge from + being directed onto a building occupant that may be nearby. + - The condensate is piped to a drain, sink, or condensate pump. + - Install earthquake straps if required by local code to the bottom 1/3 and top 1/3 of + the tank, do not install the straps to the heat pump portion. + - Set the HPWH to hybrid mode. + - Set the HPWH temperature to no more than 120 F. Setting temperatures higher than + this requires a thermostatic mixing valve at the water heater to prevent scalding. + + + + Provide a wide-angle photo of the completed HPWH installation showing the exhaust, + insulated hot water line, pressure relief valve discharge, and condensate drain line. + + + + Provide a close-up photo of the nameplate of the installed system showing the + model number and serial number. + + + + Prove a close-up photo of the HPWH Screen showing the mode. + + + + Provide a photo of the CTA-2045 Module if installed. + + + ## HPWHW Post-Installation + + Inform the homeowner on how to access the air filter to check and clean as needed.

+ The components in a common HPWH (BASC 2015) +
+ + The heat pump uses 1/3 to 1/4 of the electricity to deliver the same heat into the water in the tank as + an electric resistance element, but requires more time to do it. + Most HPWHs have electric resistencce elements to provide supplemental heat in certain modes. + The HPWH will operate less efficiently when the electric resistance elements are used + to provide supplemental heat. If the typical hot water demands are mostly satisfied by + the stored hot water in the tank, then it does not affect user comfort whether the HPWH + replenishes the heat in the tank quickly but less efficiently using the electric resistence elements + or slower but much more + efficiently using the heat pump. + + + diff --git a/src/templates/templates_config.ts b/src/templates/templates_config.ts index 00768b07..62a2b58c 100644 --- a/src/templates/templates_config.ts +++ b/src/templates/templates_config.ts @@ -6,6 +6,9 @@ import DOEWorkflowDuctlessHeatPumpTemplate from './doe_workflow_ductless_heat_pu import DOEWorkflowCentralDuctedSplitHeatPumpTemplate from './doe_workflow_central_ducted_split_heat_pump.mdx' import DOEWorkflowDuctlessHeatPumpWithoutMjTemplate from './doe_workflow_ductless_heat_pump_without_mj.mdx' import DOEWorkflowCentralDuctedSplitHeatPumpWithoutMjTemplate from './doe_workflow_central_ducted_split_heat_pump_without_mj.mdx' +import IRADOEWorkflowHPWHTemplate from './ira_doe_workflow_hpwh.mdx' +import IRADOEWorkflowDuctlessHeatPumpTemplate from './ira_doe_workflow_ductless_heat_pump.mdx' +import IRADOEWorkflowCentralDuctedSplitHeatPumpTemplate from './ira_doe_workflow_central_ducted_split_heat_pump.mdx' import OldQaHPWHTemplate from './old-qa_hpwh.mdx' import MdxPlayground from './playground.mdx' @@ -30,17 +33,29 @@ const templatesConfig: TemplatesConfig = { template: DOEWorkflowAtticInsulationTemplate, }, doe_workflow_central_ducted_split_heat_pump: { - title: 'IRA - Heat Pump Ducted', + title: 'Heat Pump Ducted', template: DOEWorkflowCentralDuctedSplitHeatPumpTemplate, }, doe_workflow_ductless_heat_pump: { - title: 'IRA - Heat Pump Ductless', + title: 'Heat Pump Ductless', template: DOEWorkflowDuctlessHeatPumpTemplate, }, doe_workflow_hpwh: { - title: 'IRA - Heat Pump Water Heater', + title: 'Heat Pump Water Heater', template: DOEWorkflowHPWHTemplate, }, + ira_doe_workflow_central_ducted_split_heat_pump: { + title: 'IRA - Heat Pump Ducted', + template: IRADOEWorkflowCentralDuctedSplitHeatPumpTemplate, + }, + ira_doe_workflow_ductless_heat_pump: { + title: 'IRA - Heat Pump Ductless', + template: IRADOEWorkflowDuctlessHeatPumpTemplate, + }, + ira_doe_workflow_hpwh: { + title: 'IRA - Heat Pump Water Heater', + template: IRADOEWorkflowHPWHTemplate, + }, } /** * Validates a TemplatesConfig object by checking if template names adhere to templateRegex pattern.
