Water Heater Installation & Replacement

Pro-Tech's current installed water heater pricing ranges from $1,572 for a 40-gallon electric tank to $4,650 for a gas tankless install. Standard gas tanks fall in between — see the pricing table for exact per-fuel, per-size numbers. Prices assume a same-fuel, same-location replacement with existing venting and connections in usable condition.

Most tank-to-tank replacements finish in a single half-day appointment — including draining and hauling away the old unit. Tank-to-tankless conversions typically take a full day because of venting changes, gas-line sizing, and mounting work. Pro-Tech confirms the timeline before booking so you know what to expect.

For families that regularly run out of hot water during back-to-back showers, or homes where floor space matters, tankless is worth it. Life expectancy is longer (often 15–20 years vs. 8–12 for a tank), running cost is lower on natural gas, and there's no reheat cycle. If your household rarely maxes out a 50-gallon tank, the payback on tankless is slower and the tank is the smarter buy.

Yes — Michigan municipalities require a plumbing (and, for gas, mechanical) permit for water heater installation. Pro-Tech pulls the permit, schedules the inspection, and includes both in the listed installed price. Homeowners can technically self-permit tank swaps but almost always come out ahead having the installing contractor handle it.
