Large Capacity 75 Gallon Gas Heaters in Milford, DE
Big families, soaking tubs and multiple showers running at once often need a 75 gallon tank or a high-recovery 50 gallon model. These heaters use larger burners, sometimes 75,000 BTU, and may need a bigger gas line and flue. We check your meter and pipe size to make sure the larger tank gets the gas it needs. A high-recovery unit can be a good middle ground when space is limited. We walk you through recovery rates so you choose the right fit.
Thermal Expansion Tank Installation in Milford
Many water utilities install pressure regulators or backflow devices that create a closed system. When water heats and expands, pressure spikes can strain your tank and fixtures. Code commonly requires a thermal expansion tank on these systems. We install a properly sized expansion tank and pre-charge it to match your water pressure. This simple add-on can help your new heater last longer.
