Professional Water Heater Installation Services for Your Home
Traditional Tank Water Heater Installation
If your household has moderate-to-high hot water demands, a traditional tank-style water heater could be the best fit. We install high-efficiency models from trusted brands, sized according to your household’s specific usage. Our team handles all plumbing, drainage, and gas/electric connections, and ensures everything is installed to code including seismic bracing, expansion tanks, and T&P relief valves where required.
Tankless Water Heater Installation
For homes that want hot water on-demand without the energy loss of tank storage, we offer full-service tankless water heater installation. These compact units are wall-mounted, energy-saving, and ideal for households that need flexibility and performance. Tankless models require precise gas sizing and specialized venting. We handle it all. We evaluate your home’s peak hot water flow rate, determine the temperature rise, and install the unit at the ideal location for both performance and accessibility.
Electric, Gas, and Propane Models
Every home is different, and so are the fuel sources available. Mr. Furnace installs all types of water heaters—electric, natural gas, and propane-powered units. Whether your home has an older panel that needs upgrading or you’re switching from gas to electric, we’ll ensure your new water heater is compatible and installed with safety top of mind. Our technicians are certified to work with gas fittings and licensed for electrical installations, so you’re always covered—no matter the setup.
Comprehensive System Upgrades
Sometimes a water heater installation requires more than just swapping out equipment. If your current system lacks proper water pressure, gas volume, or electrical capacity, we can upgrade your infrastructure as part of the installation. From running new gas lines to upgrading circuit breakers or water shut-offs, we handle it all in-house. That means fewer subcontractors, faster timelines, and work that’s guaranteed to last.
Water Heater Replacement
Replacing an aging or leaking water heater? We’ll handle removal and disposal of your old tank, assess your new system needs, and install the right unit for your home and lifestyle. Before we begin, we’ll inspect the installation area, check for corrosion or ventilation issues, and correct any code violations. Then we’ll get your new system installed and tested, and haul away your old unit for safe, eco-friendly disposal.
