Because of its' large water supply capabilities, many choose to purchase a 75 gallon water heater to provide hot water to a commercial structure or really big home. If you are in the market for one, how do you find the best model at the best value? Below are the main factors to consider.
1) GPH recovery rating. This rating tells you how many gallons of hot water the model can produce in a one hour period. The higher the rating, the faster and more efficiently a specific water heater can produce hot water. The ratings vary tremendously and more expense is usually related to higher ratings so choose one that fits your needs but does not exceed them.
2) Runs on natural gas. There are debates over what fuel source is best for big models, like 75 gallon water heaters. It is our contention, like that of many industry experts, that natural gas is the best fuel source. It is the cleanest burning, least expensive, and most effective at powering the heating elements.
3) Rust proof. Make sure the model you choose has spent time and money on putting measures in place to protect the unit from rust and other kinds of corrosion. The models that fail to, always fail faster and are, in many case, much less durable. There have been technological advances in this area that make it very affordable to add this feature so there really is no reason why the model you purchase shouldn't have it.
4) Warranty. Simply put, the model you choose should have a solid warranty. If it doesn't, chances are there is a reason. That reason is usually because the manufacturer knows that the chances of performance problems or break down are high and they can't afford to handle all of the warranty claims that will come in. Stay away from short, limited warranties.
