The coldest place on our list
About 214 days a year in Alamosa bring a low of 32°F or colder, going by the ten years to 2024, and the January low averages 4°F. No other place on our list has more freezing days or a colder January.
Garage, crawl-space and outside-wall pipes need insulation or a way to drain them. Look them over before the first hard freeze, and if one splits, call for emergency plumbing.
Water heaters in a cold climate
Water arrives in the house very cold here, so a heater works harder than it would somewhere milder. For Alamosa the tankless flow calculator assumes 42°F water coming in, while a tank is sized to your busiest hour of use.
When the heater has stopped, or water is spreading around it, we can go over water heater repair and installation by phone.
Frequently asked questions
How can I keep pipes from freezing on a very cold night?
Alamosa’s January lows average 4°F and the town logs about 214 freezing days a year. On a night like that, open cabinet doors on exterior walls, let one faucet trickle and keep the heat on, and unhook every hose well before the first freeze.
Can a tankless heater work where the water is this cold?
Yes, if it is sized for the cold. Colder supply water cuts what a unit can deliver, so the unit, gas line and venting get checked before you commit.
