If your water heater is working properly and are not experiencing any issues, you want to make sure you are doing everything to prolong the life of the water heater and its components. Regular maintenance is not only recommended, it is also part of every manufacturers warranty requirement. A yearly flush of your water heater helps prolong the life of the water heater and its components by removing sediment that builds in your water heater caused by the minerals naturally found in water.

Other upgrades such as a thermal expansion tank can counter the effects of thermal expansion. Thermal expansion is the expansion of water volume due to heating. A thermal expansion tank reduces the stress on your water heater and its various components such as as pipes and fittings. In some cities, a thermal expansion tank is required to meet local plumbing and safety codes.

A certified plumbing company like Option One Plumbing can discuss the options and benefits that are right for your home or business, keeping your budget in mind.


In addition to these savings, upgrading to a tankless water heater from a traditional storage tank water heater adds savings to your water bill. A traditional storage tank water heater needs to be filled every time hot water is used in your home. This also means it needs to continually keep the water heated, utilizing more gas or electricity costing you more money. A tankless water heater is more compact, giving you more space (example: garage) depending where it is installed compared to a traditional tank storage water heater.
