Contact Optimal Plumbing today at (414) 387-2332 to schedule a consultation or learn more about our boiler replacement services.
When an aging boiler begins to lose efficiency or reliability, replacing it with a modern, high-performance system can make a significant difference in comfort, safety, and energy savings. Recently, Optimal Plumbing completed a full boiler replacement project that showcases our detailed process, technical expertise, and commitment to doing the job right the first time.
For this project, our goal was to safely remove an existing boiler and install a new high-efficiency MODCON ELX-800FBN boiler, seamlessly integrating it with the building’s existing infrastructure. Every step was planned to ensure safe operation, code compliance, and long-term reliability.
Safety always comes first. Our team carefully locked out and tagged out all electrical and fuel sources before beginning work. The existing boiler was isolated from the hydronic heating system, fully drained, and disconnected from all associated components, including gas piping, water lines, electrical connections, controls, and venting. Once disconnected, the old unit was removed from the site for proper disposal.
The new MODCON ELX-800FBN boiler was set and secured in the location of the previous unit. Our plumbers reconnected all critical systems, including:
Natural gas piping, modified as needed for a secure and safe fit
Supply and return water piping aligned to the new boiler’s specifications
Venting and air intake adjusted to meet manufacturer requirements and local codes
Electrical supply and controls integrated with the existing system
Every connection was completed with precision to ensure safe and efficient operation.
Once installed, the hydronic system was refilled, purged of air, and thoroughly checked for leaks. We then performed a complete system startup following manufacturer specifications, testing all safety controls and performance metrics to confirm the boiler was operating efficiently and correctly.
Throughout the project, we maintained a clean and organized work area. All debris and materials were removed, and the old boiler was disposed of in an environmentally responsible manner—leaving the site clean and orderly upon completion.
Optimal Plumbing handled all required municipal and state permits for this boiler replacement. The new MODCON ELX-800FBN boiler is backed by a one-year parts and labor warranty, providing added peace of mind for the property owner.

Honest, upfront pricing

Miltos was so pleasant and professional. He connected and moved our laundryroom water lines and washing machine expel behind the wall to our basement. He installed levers on our main water lines. He was very neat and conscientious. Would give Optomal Plumbing 10 stars! The owner and office staff were excellent. We will continue to use this company.Posted on Google![]()

Arrived promptly, explained everything very clearly. Addressed several issues, was very nice to get numerous annoyances repaired. Very pleased with my experience. NOTE: No compensation was provided for this review. UPDATED: I used Optimal for a second job. This time, I asked for a high quality outdoor faucet. I am annoyed with the cheap versions that always fail. Miltos researched some options, and eventually we agreed on a the product that seemed the best for me. I now regret not updating all my outdoor faucets! It is so nice having a high quality outdoor faucet. It seems like something minor, but every time I use the new faucet I am thankful for the work Optimal provided. If you are tired of outdoor faucets that are a nuisance to turn on and off, turning the faucet forever, and feel like they will cr;umble in your hand, I fully recommend upgrading to the faucet that Optimal recommended. Well worth the money.
