Gas Boiler Removed | Mass Save Rebate | Full Electric Heat Pump Solution
When a homeowner in Acushnet, Massachusetts contacted us, they were dealing with a leaking, outdated gas boiler that was responsible for both their home’s heating and hot water. Not only was the system inefficient, but it was also taking up a significant amount of space in a utility closet. As the heating season approached, they knew it was time for a safer, more efficient solution.
❆ The Problem:
The original system was a combined gas boiler that supported baseboard heating and domestic hot water. Over the years, it had deteriorated badly and was now leaking. The space it occupied was cramped, and the homeowner wanted to transition to a cleaner, electric-based system that could take advantage of their existing solar panel array.
We arrived to assess the system and realized the best approach would be to completely remove the gas boiler and replace it with two components:
- A dedicated electric hot water heater for domestic use.
- A fully ducted and ductless mini split heat pump system for zoned heating and cooling.
The Solution:
We designed a custom HVAC solution using Fujitsu’s Airstage multi-zone mini split system, all powered by electricity — qualifying the homeowner for a Mass Save $10,000 rebate.
Electric Hot Water Heater Installed
We installed a high-efficiency Rheem electric hot water heater in place of the old tankless boiler attachment. This opened up floor space and simplified maintenance moving forward.
Multi-Zone Fujitsu Airstage Mini Split Heat Pump
The centerpiece of the upgrade was a powerful multi-zone condenser mounted discreetly along the exterior of the home. This unit supports:
- One ducted low-profile air handler installed in the attic
- Two wall-mounted air handlers — one in the basement and one in the main living area
Each zone has its own thermostat, allowing the family to control temperatures independently.
Air Distribution
Using the attic as a distribution zone, we ran ductwork to all three second-floor bedrooms and a central bathroom. A central return and digital Fujitsu thermostat provides accurate control and better airflow.
For the basement and first floor, we installed clean-looking wall-mounted heads that blend into the living spaces and provide both cooling in summer and heating in winter.
Why This System Works:
- $10,000 rebate through Mass Save (full home upgrade)
- Home already had solar — this system takes full advantage
- 12-year parts and compressor warranty through Fujitsu Elite Program
- Zoned control for bedrooms, bathrooms, basement, and living room
- No fossil fuels, no flue pipe, and reduced energy bills
Frequently Asked Questions
Q: What’s the benefit of switching from a gas boiler to a mini split?
Mini splits are electric, so they work well with solar systems. They also offer both heating and cooling in one system, reduce noise, eliminate combustion-related risks, and can cut utility costs when installed properly.
Q: What kind of maintenance do mini splits require?
Aside from occasional filter cleaning and coil checks, mini splits are low maintenance. Annual servicing helps keep the system efficient and long-lasting.
Q: Can a mini split really heat the whole house in winter?
Absolutely. We installed a properly sized Fujitsu Airstage system with both ducted and ductless zones, providing warm air even on the coldest days. These systems are designed for New England winters.
Benefits of Zoned Comfort
With this setup, each floor of the home has its own heating and cooling zone. This gives homeowners full control over comfort and efficiency. No more overheating unused spaces — each area stays just how the homeowner wants it. It’s especially ideal for multi-level homes or families with varying temperature preferences.
Mini Split vs. Gas Boiler: A Clear Winner
Traditional gas boilers only provide heat — and with significant energy loss through piping and baseboards. Mini splits, on the other hand, provide both heating and cooling, with high efficiency ratings and precise zone control. They’re also easier to install, don’t require chimney venting, and pair perfectly with clean energy sources like solar. Plus, the environmental impact is dramatically lower.
How the Mass Save Rebate Works
We guided the homeowner through the Mass Save Heat Pump Rebate Program, which provided a $10,000 rebate for upgrading their entire home with efficient heat pumps. As a Fujitsu Elite Contractor, we also ensured the system qualifies for the full 12-year parts and compressor warranty. We helped with the paperwork and made the process stress-free.
Customer Satisfaction
After the install, the homeowner shared how much quieter and more comfortable the system was — especially in the bedrooms and basement. The ability to fine-tune temperatures room by room made a huge difference. They also appreciated the extra closet space where the old boiler and piping used to be.
Serving Acushnet and Beyond
This project is a perfect example of how a modern ductless mini split system can replace an aging boiler, especially when paired with solar and incentives like Mass Save. The homeowner now enjoys a quieter, cleaner, and far more efficient comfort system — all installed by the pros at Armus Mechanical.
