Bigger is always better:) So a 50 gallon tank is prefered over a 40
gallon, for say laundry. plus a larger tank experiences less thermal
stress from heating and cooling completely when you run out of hot
Buy the longest warranty you can, normally 12 years, longer warranty
means less overall cost per year. plus better quality, pricer tanks
more likely to have brass drain valves, cheap tanks tend to have
plastic valves:( real junk they break easy and often drip after just
most tanks are about 40,000 BTU, some cheap tanks 34,000 BTU
I prefer my 75,000 BTU tank 75 gallon tank. It cost more, but no cold
Dont stress too mucxh about what you buy, confirm it will fit the
space. do replace the vent pipe they rust over time, and check out the
chimney or have it iunspected to make sure its safe. bad chimney caps
can be dangerous, detoriated linings etc.
Think of this.......
most people dont have to buy a tank till they are at least 20 years
by 70 most dont need to buy one again.
So they need to buy one for 50 years MAX.
say the average tank lasts 10 years, if you buy good quality.
so you buy 5 tanks in a lifetime, and probably less. because previous
owner just installed one, lived for a time in a apartment or rental,
hot water tanks are a minor inconvenience and overall minor cost too.
figure 500 bucks for new tank installed, 10 year life of 12 year
50 bucks a year. less than one nice candy bar cost per week.
