Water Heating Systems

Trust Alvin Hollis to install your home's water heater.There are four ways to heat a home’s hot water. We’re experts at each one.

Domestic water heaters using tanks (usually with a 30-100 gallon capacity) provide a large volume of dependable, low-cost hot water. Fuel sources usually are natural gas, electricity or propane. They are the most common way to heat water in the United States.

Today's most popular "green" hot water solution. No matter how many showers and loads of laundry, no matter how deep the whirlpool, your system will not run out of hot water with a properly sized tankless water heating system. They’re energy efficient and provide hot water on demand at the precise temperature needed.

Similar to a tank system, an indirect water heater is connected to a gas or oil boiler and receives water heated from that system, which an internal heat exchanger in the tank re-heats to keep hot.

An even “greener” hot water solution that uses an outdoor solar panel to capture the sun’s rays and convert it to energy to heat water. To learn more about Alvin Hollis’s capabilities as a solar power contractor, please visit this page.
