"The initial build went reasonably well. We did find problems which they did come back and fix. I noticed a railing support that was cracked. I was told that I must of done it, that was that. The plugs that cover the screw holes in the stairs are falling out. I looked for some at Home Depot, but couldn't find the right color. I still had Chase's cell #, so I texted him and asked if he could send me some plugs, and I would do it myself. No response. Tried again the next day, still no response. I'm not surprised. Aging the build was decent, price was higher than most. Now that nearly 2 years have gone by, and customer service should be anticipated, nothing. Never again."

Water Heaters questions, answered by experts

If you’re having problems with your hot water heater and it’s 10 to 15 years old—the typical life span of a gas hot water heater—you may want to consider replacing it rather than repairing it. Water heater replacement costs about $1,300 on average. If your water heater is younger than nine or 10 years, paying for repairs is most likely worth it. You can always have a plumber assess your fixture to see what it would cost to fix it and then decide if it’s more cost-effective in the long run to replace it.

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.

Boilers are used mainly for central heating, and water heaters are used for ordinary household water use. In fact, a conventional boiler works best if your home already has a water heater system in place. Sometimes a boiler can be combined with indirect water heaters. But there are also premade combination boiler heaters.
