Gas & Electric Storage Tanks

Residential storage type tank water heaters are the most common water heater products sold in the USA today. They are available in gas and electric models and come in 30, 40, 50, 65, 75, 80 & 100 gallon capacities. If you currently have a storage type tank water heater, we generally recommend a like-for-like replacement unless you are looking for more hot water or are interested in a high efficiency water heater.
Heat Pump Water Heaters
Heat pump water heaters offer a different type of heating compared to traditional gas or electric models. Heat pump water heaters are one of the most efficient water heater products available today. These products use condensing technology and recapture energy used to heat the water heater. Most condensing type heat pump water heaters are 4% efficient, that’s about 30% more efficient that a traditional gas storage tank water heater. Heat Pump Water Heaters are not new to the market, but they are getting more attention lately. This is due, in part to the lower Nox emissions, higher efficiency ratings and the Bay Area Air Quality Management Districts Rule 9-6. The BAAQMD’s rule 9-6 will require bay area residents to convert to a heat pump water heater when a water heater fails, starting in 2027. Read more about this major upcoming change beginning in 2027.

Residential Tankless

Tankless water heater products have been all the rage for the past few years. They are designed to heat water “on demand”. When you open a hot water faucet the tankless water heater turns, heats the water and delivers the hot water to your fixture. However, the best feature about tankless water heaters is that they are small, compact and can be installed in a variety of places. Tankless water heaters range in efficiency from .82% to .96% efficiency depending on the model.
Commercial Tank Water Heaters

Commercial water heater products are generally designed for high hot water demand or to meet temperature requirements. We often install commercial water heaters for apartment communities, HOA’s, restaurants and other commercial businesses. Commercial water heaters are designated by the BTU input of the water heater, the higher the BTU’s the more hot water a commercial water heater can produce. If you have a commercial water heater problem try to have the model # and BTU rating available when you call for service.
