Heatpump Model and Installer Research

August 2022, we are looking into buying and installing one or more heatpumps for our oil-heated forced-hot-water home to reduce our winter oil use and to give us some cooling during the summer heat/humidity.

Heat pump devices

Mitsubishihigh demand, long lead times (8+ months?)
LGOne Lex List member reported issues with non-LG thermostat; system would stay on, but this might be related to the usage learning curve; pressure relief valve issue; be sure to verify experience of installers and techs
SamsungSold/installed by Homeworks
GreeSold/installed by Tetra

Note that whatever heat pump you choose, to get rebates, it has to be on the MassSave list, see:

Concerns to address

  • Will your electrical feed need to be upgraded? (If you have 200 Amp service, will that be enough to support one or more heat pumps?)
  • Temperature range. Make sure your units can handle the temps in our area (eg, -20 to 110F)
  • Will the unit work with your existing thermostat or must it be replaced?
  • Will (and if so how will) heat pump work with existing home heating system?
  • Verify experience of Installers and Tech support


  • Get wall units for rooms with doors you can close (to isolate heat/cool to the room)
  • Heat pump for your hot water. will chill your basement if it's in the basement

Analysis & Comparison, heat pump vs oil boiler

We got a quote from a company for the cost of a whole-house solution. There are two rebates available to us, approx $5k since we're going whole-house, and $10k if we also sign an agreement that we will only use oil heat in an emergency.

Description of quoted system: TBD


We have an oil-fueled boiler forced hot water heating system. We have a single window air conditioner that the heat pumps would replace. Here are the cost factors for our situation.

Assuming for the purpose of this analysis:

  • Energy costs stay the same over the analysis period (oil and electricity)
  • Maintenance costs stay the same over the analysis period
  • We are not considering electricity savings by using heat pumps over the one window air conditioner we're using
