"Went great. Maddie H. came by and found the problem with my old water heater. She setup the install for me. Bradley K. installed the new water heater the next day and did an excellent job. Both individuals were very knowledgeable and a pleasure to work with. Great job to everyone concerned. Thanks!"

"Tim did an excellent job installing two new pendant lights in our kitchen. He kept necessary drywall cuts to a minimum, and even cleaned up the drywall dust afterward. The end result was exactly what we wanted, at a very fair price."

"Excellent! This is our 2nd home renovation and remodel with Double Tap HVAC and Electrical. Our first home we utilized Double Tap to ensure the sale of our home by renovating and updating 2 full baths, and all repairs listed per the inspection report. With Double Tap being a licensed contractor, electrician and HVAC it was a total win versus using several companies to complete the job! Outstanding work ethic, affordable pricing, impeccable knowledge base, and consistent daily work to get the job completed on time! We used Double Tap again for our newly purchased home to renovate our entire living space to create an open floor plan. This entailed wall removal, beam / support installation, mold removal, subfloor leveling, attic/ crawl space inspection, floor installation, and a complete staircase reconstruction. Double Tap has also made after hours HVAC emergency service calls for us. I highly recommend Double Tap HVAC and Electrical and will always be a loyal customer recommending to anyone that owns a home or business!"

Install Boiler FAQs, answered by experts

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs.
