Can you switch to a tankless water heater from a heater with a tank?

• <div><p>Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.</p></div>

Q: Can I use multiple tankless water heaters?

• <div><p>You can use multiple tankless water heaters, but that doesn&rsquo;t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you&rsquo;re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations. </p></div>

Q: What adds more value: a heat pump or gas water heater?

• <div><p>While heat pump water heaters are more expensive than gas-powered water heaters, the ROI is higher for heat pump units. Not only are heat pump water heaters more energy efficient, meaning immediate savings on your energy bill, but they also last longer than traditional gas versions, meaning you won't have to buy them as often.</p></div>

Q: What type of water heater is best for my home?

• <div><p>You have more options for water heaters than ever before. The best one for your home depends on your hot water usage and budget. Some of the more <a href="https://www.angi.com/articles/types-of-water-heaters.htm">common types of water heaters</a> are the conventional gas heater, a heat pump water heater, or a tankless heater for smaller homes or those with less water demands. Some uncommon types are solar and point-of-use systems. Some homes may have a combination of two units, such as a large heat pump heater and a backup point-of-use system. </p></div>

Q: Are water heater pans required by code?

• <div><p>Yes, most municipalities have codes that require water heaters to have pans. A pan is necessary when a water heater or hot water storage tank is installed in an area where water leakage could cause damage, such as an attic, second floor, or finished basement. Tankless water heaters are not required to have a pan since there is no storage tank.</p></div>

"Jesse removed old baseboard water radiators in our bathroom. This was the start of a bathroom remodel. When bathroom was finished he came back and installed a new and much smaller baseboard radiator. He was friendly, efficient, came on time, cleaned up any mess and all around very professional. Very happy with his work! Would highly recommend him."

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet. I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."
