"Called Stephen MIchael for an estimate.  He came out the next nite, gave me the estimate and I hired him.  He
came the next nite in the rain exactly at the time advised.  Loaded a hugh truckload of old wood, fencing, etc on the
truck..got it all.   Then he even swept up the driveway in the rain.  Very professional and I was extremely happy.  
Would not hesitate to hire again.   "

"Jon and his crew removed an old oil boiler and water tank and replaced the entire system with a gas boiler and tankless water heater. The crew worked steady and hard for 2 days and did a great job! Everyone was professional, knowledgeable and they cleaned up the space after they were finished. Jon is easy to get ahold of and communicate with and answered all my questions! We will use them again for any future needs and definitely recommend them!"

"They installed a new faucet in the rear of my home and replaced the front outside faucet and the cellar shutoff to it. They removed and installed a new toilet very quickly and did not encounter any issues. They were prompt and friendly and barely intruded with our normal home activities. I was amazed with the efficiency and quality of their work. I highly recommend Aquarius Plumbing. I highly recommed them."

Install Boiler FAQs, answered by experts

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.
