Ten months a year of hot water demand
Homes in Lacey need heat September through June, close to ten months a year. Your water heater is part of that, working alongside the furnace most of the year rather than just a few summer months off.
A new storage water heater has to meet a federal efficiency minimum, and that minimum is not one number. It is set by a formula tied to the tank's rated volume, applied separately across four draw patterns, so two tanks of the same type but different size answer to different minimums. Whoever installs yours should size it to your household first, then match it to the rule that applies at that size.

- How do I know it's time to replace my water heater?
- Look at how the tank is behaving, not just how old it is. Rust colored water from the hot tap, rust on the outside of the tank, or water pooling underneath all mean the tank itself is failing, and a leaking tank can't be repaired. If it still makes hot water but you run out faster than you used to, or you hear popping and rumbling, that's usually sediment built up on the bottom of the tank, and it's worth having a contractor check whether a repair still makes sense or whether it's time to replace it.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your home can support. A tankless unit heats water as you use it instead of storing it, so you don't run out during a long shower or back to back loads of laundry the way you can with a tank. Installing one often means new venting and sometimes a larger gas line or electrical circuit, since a tankless unit draws more power in the moment than a tank does. A contractor can look at your home's setup and tell you what switching would actually involve for the space you have.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and heat it as you use it instead, so you don't run out partway through a shower. The unit itself is much smaller than a tank and usually mounts on a wall, which frees up floor space in the utility room or closet where the old tank sat. Venting is different from a tank water heater, and the gas line or electrical circuit feeding it may need to be sized up for the higher demand when it's running. A contractor will need to check your home's existing setup to know exactly what has to change.
