Situation

K.D. owns a rural single-family residential property in western Dracut adjacent to the Pelham NH border. Western Dracut’s border area with Pelham NH includes several properties on propane (rather than natural gas) reflecting the historical pattern where natural gas distribution infrastructure did not extend to the more rural western Dracut properties, and where Pelham NH’s substantial propane retention pattern extends across the border into adjacent Dracut rural areas.

K.D.’s property has approximately 2,600 sq ft two-story configuration with 1988 subdivision construction on a larger rural-suburban lot. Existing HVAC configuration: 18-year current propane furnace (replaced approximately 18 years ago; original 1988 furnace replaced earlier), matching central AC installed approximately 18 years ago, 500-gallon underground propane tank in side-yard buried at approximately 4-foot depth per typical residential installation, propane water heater in basement mechanical space (K.D. plans separate replacement in future upgrade cycle), forced-air ducted distribution throughout.

K.D. has been considering coordinated propane-to-heat-pump conversion for approximately 2 years driven by propane operating cost trajectory (propane prices during 2022-2024 heating seasons ranged $2.80-$4.60 per gallon delivered, with substantial year-over-year and even month-over-month variation), reliability concerns with the 18-year propane furnace, and interest in fossil-fuel elimination for both environmental and operating cost stability reasons.

K.D. requested Rivic assess replacement options with priorities: (1) complete propane elimination including underground tank decommissioning to reduce ongoing propane operating cost and tank maintenance liability, (2) Mass Save Whole-Home Heat Pump rebate qualification (propane-to-heat-pump conversion qualifies for Whole-Home rebate scope), (3) fossil-fuel elimination given long-term propane cost trajectory concerns, (4) mid-tier equipment specification matching K.D.’s budget priorities.

Diagnostic and Assessment

Andrew Samples conducted the initial diagnostic assessment. Key findings: (1) 18-year propane furnace with declining efficiency (approximately 74-80% effective from 82% AFUE nameplate), heat exchanger inspection showed corrosion but no cracks yet, (2) 18-year central AC with refrigerant charge decline (approximately 15-25% below design), (3) existing ductwork in acceptable condition suitable for heat pump conversion, (4) 200A electric service adequate for heat pump installation with capacity margin, (5) 500-gallon underground propane tank buried at 4-foot depth in side-yard — requires licensed propane contractor for decommissioning per applicable regulations, (6) propane supplier customer relationship: K.D.’s propane supplier (verified as one of the common Merrimack Valley propane suppliers) requires standard supplier notification for account closure and tank removal coordination.

ACCA Manual J load calculation determined property heating load at 4°F winter design of approximately 58,000 BTU/hr and cooling load at 88°F summer design of approximately 38,000 BTU/hr.

Solution: Mid-Tier Bosch IDS 2.0 with Propane Elimination

Rivic recommended Bosch IDS 2.0 mid-tier variable-capacity heat pump 4-ton nominal capacity with existing ductwork utilization matched to K.D.’s budget priorities. Equipment specification: (1) Bosch IDS 2.0 inverter-driven variable-capacity outdoor unit, (2) Bosch matched indoor air handler with variable-speed ECM blower, (3) Bosch standard programmable thermostat, (4) 5-year Bosch parts warranty + 10-year compressor warranty.

Existing ductwork utilization: minor duct sealing improvements at accessible joints; supply and return grille inspection confirmed adequate condition; variable-speed ECM blower matched to Bosch IDS 2.0 variable-capacity operation.

Propane furnace and central AC decommissioning: 18-year propane furnace and central AC removed with proper refrigerant recovery per EPA Section 608; propane piping capped at previous furnace location; remaining propane in furnace supply line properly handled per licensed propane contractor coordination.

Underground Propane Tank Decommissioning Coordination

Kathleen Brennan coordinated the underground propane tank decommissioning scope with a licensed propane contractor. The propane tank decommissioning scope typically requires specific licensed handling that HVAC contractors do not directly perform — comparable to Rivic’s approach with oil tank removal scope (licensed oil tank contractor subcontracted for oil tank removal on oil-to-heat-pump conversions).

Underground propane tank decommissioning scope:

• Propane supplier notification: K.D.’s propane supplier account closure and coordination for any remaining propane recovery or transfer
• Licensed propane contractor engagement: Rivic coordinates licensed propane contractor subcontracted for tank decommissioning scope
• Tank decommissioning options: (a) complete tank removal (excavation and removal of the underground tank — higher cost but eliminates the tank entirely from property), (b) tank in-place decommissioning (tank purged, filled with inert material like sand or slurry, and left in place — lower cost but tank physically remains on property)
• Cost range: $1,800-$4,200 typical for 500-gallon tank decommissioning scope depending on selected option and specific site conditions

K.D. selected complete tank removal ($3,600 in this case) for future property flexibility and elimination of the tank as a property feature.

Propane vs Natural Gas Emergency Contact Differences

An important operational note for propane-served properties: propane emergency response differs from natural gas emergency response in significant ways:

• Natural gas emergency: customer contacts the natural gas utility (Eversource Gas of Massachusetts at 800-592-2000 for Merrimack Valley MA properties, Liberty Utilities at 855-349-5697 for NH natural gas properties). Utility dispatches emergency response and coordinates with local fire department as needed.
• Propane emergency: customer contacts the propane supplier’s emergency line (each propane supplier has their own emergency contact number; common Merrimack Valley suppliers include AmeriGas, Suburban Propane, Rymes Propane, Fisher Propane, Palmer Gas & Oil, and various regional suppliers). If the customer cannot reach the propane supplier or if the situation warrants, contact 911. Fire department response is common for propane leak scenarios given the specific fire and explosion risks associated with propane’s heavier-than-air characteristics.
• Post-conversion: after propane elimination (as in this case study), K.D.’s emergency response scope becomes electrical (National Grid electric service reliability and emergency response) rather than propane — simplifying emergency planning.

Outcome

Installation completed over 5 days for HVAC scope plus 1 additional day for propane tank decommissioning (coordinated with licensed propane contractor). Post-installation first-year operational verification: heat pump operated reliably through the first winter including cold-snap periods with outdoor temperatures reaching 3°F to 6°F range. Bosch IDS 2.0 inverter-driven variable-capacity operation delivered efficient part-load performance.

Ongoing Operating Cost Change

Post-installation first-year utility monitoring: total electric operating cost approximately $1,540 for combined heating and cooling. Previous year utility costs: propane heating approximately $2,180 (varying with propane price fluctuation; some months substantially higher during peak demand), electric cooling approximately $580, combined approximately $2,760/year. Annual operating cost reduction approximately $1,220/year — larger reduction than typical gas-to-heat-pump conversions reflecting propane’s higher cost per BTU compared to natural gas.

Investment Summary

• Heat pump installation cost: $23,600 (Bosch IDS 2.0 4-ton equipment with matched air handler, installation labor, ductwork improvements, refrigerant charging, commissioning)
• Propane tank decommissioning (complete removal option): $3,600 (licensed propane contractor subcontracted scope)
• Combined total installation cost: $27,200
• Mass Save Whole-Home Heat Pump rebate: $10,000 (propane-to-heat-pump conversion qualifying for Whole-Home scope)
• IRA 25C federal tax credit: $2,000
• Net investment: $15,200 after all rebates and tax credits
• Annual operating cost reduction: approximately $1,220/year
• Simple payback: approximately 12 years on operating cost alone; substantial additional value from propane elimination (no more monthly delivery scheduling, no tank maintenance, no propane price volatility exposure), tank removal (no ongoing tank liability), and coordinated system modernization

Frequently Asked Questions About This Case Study

Does Mass Save Whole-Home Heat Pump rebate apply to propane conversions like it does for natural gas conversions?

Yes. Mass Save Whole-Home Heat Pump rebate ($10,000) qualifying scope extends to complete conversions from any fossil-fuel heating source (natural gas, oil, or propane) OR from electric resistance heating. Propane-to-heat-pump conversion qualifies identically to natural gas-to-heat-pump conversion for Whole-Home rebate scope where the installation eliminates all fossil-fuel heating on the property. Rivic’s diagnostic assessment includes rebate qualification evaluation as part of initial project planning. Propane properties represent approximately 15-20% of Rivic’s installation scope depending on service area (higher percentage in Pelham NH and western Dracut/Haverhill rural areas where propane retention is substantial; lower percentage in Methuen/Lawrence/urban areas with natural gas distribution).

Can Rivic complete similar propane-to-heat-pump conversions in my western Dracut, Pelham NH, or other Merrimack Valley propane-served property?

Yes for properties with suitable configuration. Prerequisites: adequate 200A electric service (typical for properties with modern electric infrastructure), existing ductwork suitable for heat pump conversion or property configuration supporting multi-zone ductless configuration, propane tank scope suitable for decommissioning coordination (typical residential 250-gallon or 500-gallon aboveground or underground tanks are all suitable), and propane supplier account closure coordination (Rivic handles through Kathleen Brennan’s project management). Rivic subcontracts licensed propane contractor for tank decommissioning scope. Typical installation range for propane-to-heat-pump conversions: $22,000-$38,000 gross including tank decommissioning depending on equipment tier and tank scope, $10,000-$26,000 net after Mass Save Whole-Home rebate and IRA 25C credit.

Why coordinate underground propane tank removal instead of leaving the tank in place?

Both options (complete removal vs in-place decommissioning) are valid; K.D. selected removal for property flexibility. Considerations: (1) In-place decommissioning ($1,800-$2,600 typical) leaves the tank physically on property but properly purged and filled with inert material — tank presents no ongoing hazard but remains a property feature that may complicate future landscape work, future property sale disclosure, or future property redevelopment. (2) Complete tank removal ($2,800-$4,200 typical for 500-gallon underground) eliminates the tank entirely including excavation and disposal — eliminates any ongoing property feature and simplifies future property flexibility. Cost difference between the two options is approximately $1,000-$1,600; property owner priorities vary. Rivic’s coordination scope handles either option based on property owner preference.

How does propane emergency response actually differ from natural gas emergency response?

Natural gas emergency: customer contacts the natural gas utility (Eversource Gas of Massachusetts at 800-592-2000 for Merrimack Valley MA properties, Liberty Utilities at 855-349-5697 for NH natural gas properties). Utility dispatches emergency response and coordinates with local fire department as needed. Propane emergency: customer contacts the propane supplier’s emergency line (each propane supplier has their own emergency contact number; common Merrimack Valley suppliers include AmeriGas, Suburban Propane, Rymes Propane, Fisher Propane, Palmer Gas & Oil, and various regional suppliers). If the customer cannot reach the propane supplier or if the situation warrants immediate response, contact 911. Fire department response is common for propane leak scenarios given the specific fire and explosion risks associated with propane’s heavier-than-air characteristics (propane accumulates in low areas rather than dissipating like lighter-than-air natural gas). Post-conversion to heat pump, emergency response scope simplifies to electrical (utility) rather than fuel-based.

What’s the typical operating cost comparison between propane and heat pump operation?

Heat pump operation typically delivers substantially lower operating cost than propane heating — typical annual reduction $800-$2,000+ depending on property size, climate, and propane price. Propane’s cost per BTU is typically 40-80% higher than natural gas per BTU (varying with propane price and natural gas price). Heat pump efficiency (250-350%+ effective vs propane furnace 80-90% effective) additionally compounds the operating cost advantage. K.D.’s specific case ($1,220 annual reduction) is typical for a 2,600 sq ft property with 18-year propane furnace. Larger properties or higher-usage properties can see larger absolute annual reductions. Rivic’s diagnostic assessment includes estimated operating cost comparison based on individual property’s propane usage history and expected heat pump operation.
