Exceptional Efficiency
Uses 60 to 70% less energy than traditional electric water heaters. Qualifies for government energy rebates that offset the initial investment.
Fast Payback
Higher upfront cost ($3,000 to $5,500 installed) but pays for itself in 3 to 5 years through significant monthly energy savings.
Ideal Installation

Common questions about water heater installation, repair, and maintenance.
How long do water heaters last?
Tank water heaters typically last 8 to 12 years. Tankless water heaters can last 15 to 20+ years with proper maintenance. Regular annual flushing (for tanks) or descaling (for tankless units) helps extend the lifespan of either type significantly.
Should I get a tank or tankless water heater?
Tankless provides unlimited hot water and saves 30 to 40% on energy, but costs more upfront. Tank heaters are more affordable initially but have higher operating costs and limited capacity. We help you choose based on your household size, hot water usage, and budget.
What size water heater do I need?
For most families of 3 to 4, a 50-gallon tank or a tankless unit rated at 8+ GPM is sufficient. Commercial properties need sizing based on peak demand. We will assess your needs during a free consultation and recommend the right system for your situation.
My water heater is leaking. Is that an emergency?
Yes. A leaking water heater can cause water damage, mould, and electrical hazards. Turn off the water supply and call us immediately for emergency service. Even a small leak can escalate quickly, so do not wait to have it inspected.
