"Damien arrived on time and determined our issue quickly and corrected our clogged pipes. We also asked him to check out another issue. He stayed and fixed this issue as well. He also cleaned everything up before leaving. A true professional. We will definitely be hiring him again and recommending him to all of our friends. Thanks again Damien"

"I am absolutely thrilled with Domination's Service.  A highly skilled plumber (today Tristen) comes quickly, determines exactly what the problem is, recommends the best products to solve the problem, then the service manager calls with pricing so there are no surprises, and Tristen does an excellent job of fixing the problem and installing new products.  I have had this company come a couple of times and I am always completely satisfied with the excellent work they do.  I highly recommend Domination."

"They first came out to do a routine check and informed us of what we should / needed to do to have our fire place perform better. The quote they provided was very reasonable. We decided to install a rain cap after the sweep and getting an appointment was very easy. The technician arrived early and completed the work quickly."

"Jason and Noah did a great job replacing the old knob and tube wiring and installing a three-way switch on a dark flight of stairs. They worked on our project from start to finish, without interruption, which we greatly appreciated. They did a good job patching the holes they had to make in walls and ceilings in order to run the new wires. They cleaned up nicely at the end of each day and stored their tools out of the way in our basement overnight. At the end of each day, Jason gave us a walk-through of the progress he and Noah had made during the day. He had a positive, professional, "can-do" approach to the work and challenges of the project."

Install Boiler FAQs, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

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.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

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.
