  • Step #5 – The Valves and Supply Lines:- Low, you must connect the supply line, shut off valve, and the sediment trap. The gas shut-off valve is an important component. It must be attached to the stainless steel corrugated supply line. The sediment trap must be connected to the steel supply line too. These connections should be tightened using nuts and bolts. You can use an adjustable wrench to tighten the nuts.

Once the gas shut off valve is connected, you must attach the water shut-off valve. These water shut-off valves should be connected to the tankless water heater. The water pipes must be supported using bell hangers. You can use copper water pipes. Don’t forget to solder the copper joints.

  • Step #6 – Sniffing Gas:- During installation, gas may bleed from the pipes. You must make sure there are no gas leaks. Use a gas sniffer to ensure if there are no gas leaks. The gas sniffer must be used to check all the joints.
  • Step #7 – The Last Three Steps:- 
  1. Piping and elbows
    The tankless water heater is now prepared for elbows, vent piping, and connectors. The connector has to be slipped and secured with a hose clamp. The elbows and vent pipes must be secured.
  2. The interior and exterior thimble
    Through the outside wall, you must install a strong metal wall thimble. All shingles must be removed. The interior and exterior parts of the thimble must be installed. Don’t forget to include all the components of the vent pipe.
  3. Powering the water heater
    The final step would be installation, plugging, and insulating the water heater and its pipes. Connect the tankless water heater to its power supply (microprocessor and thermostat). The hot pipes must be protected using pre-shared pipe insulators. Now, you can turn on the power, gas and start enjoying the warm water.

tankless vs tank water heater

Tankless Vs Tank Water Heaters

There are 2 main kinds of water heaters available in the market- Tank water heater or water heater without a tank. Today, we will discuss the main difference between the tank water heater and the tankless water heater.

What are Tank Water Heaters?

Generally, houses have tank water heaters which are otherwise known as water heaters with storage. As the name suggests, these water heaters come with a tank that can hold 20 to 120 gallons of water with gas burners or heating elements. At the top, the tank water heaters have hot water and at the bottom, these water heaters have incoming cold water.

This feature is given so that you get hot water consistently. Tank water heaters tend to lose heat via the walls of the tank. The tank comes with insulation, however, the temperature difference across this wall with insulation is huge. Thus, even with the large insulation, the heater tends to lose heat considerably.

What is a Tankless Water Heater?

Tanklesstankless water heater, when it comes to tankless water heaters then there is no considerable heat loss because in it the water is heated when there is a requirement for hot water. In a tankless water heater, there is no water filled in it for standby. The system in the heater comes in two types whole house heaters and point-of-use heaters. Point-of-use heaters are put in one particular faucet and it supplies hot water to just one fixture.
Tankless water heaters are energy-saving and supply hot water constantly.tankless vs tank water heater
In standby, the water tends to lose its heat and to address this issue, tankless water heaters come into play. These types of heaters are generally installed in the place where you need the water heater like in the bathroom. One of the great features of a tankless water heater is that you will consistently have hot water and you will not run out of it considering that there is enough water heater to satisfy the demand for hot water. Additionally, they don’t have the loss of standby hot water. This is because no hot water is there to store in the tank thus no loss of heat is there when the heater isn’t running.

  • The Heating Elements:

One of the main advantages of tank water heaters is that their heating elements are quite small. This is because a defined volume of water is stored in the tank and as it remains arranged as the hot water is used, an efficiently sized tank heater can cater to the hot water demand of the family without the need for electricity or gas to heat the water.

On the other hand, tankless water heaters generally have large-sized burners as compared to tank water heaters. A normal whole-house tankless heater that allows a family to use two showers simultaneously will have the burner generating 180,000Btu/hour. The biggest tankless water heaters come with burners with more than 300,000Btu/hour. If you want this much natural gas you need a burner with a greater gas supply.

The tankless water heaters with a substantial gas line need huge combustion of air. Whereas, a small tank of 125,000Btu/hour variant that is working at its maximum capacity needs around 30 cm of air to complete the combustion. At the same time, a 180,000 Btu per hour variant needs up to 45 cfm of air working at its maximum capacity.

  • The Flow Rates

A tankless water heater has a flow rate of 0.5 or 0.6 GPM. This means that at flow rates lesser than this the water would not come. This is a big problem for people with bathroom faucets.

  • Cost

A tankless water heater can cost double that tank water heater. The price entirely depends on the model and size that you choose. If you are going for a point-of-use tankless heater, then you would have to buy additional units. A normal tank water heater providing two showers simultaneously can come with a price tag of $700.00. The normal tank water heater comes across $220, on the other hand, a single tankless heater comes with a price tag of 980.
While the tankless water heater seems costly right now, it would help in saving a significant amount of money over the year.

5 Reasons Why You Should Move To a Tankless Water Heater

Tankless water heaters are the new trend for homes and commercial places. Earlier, the water heater was considered a huge and bulky appliance that comes with a complicated mechanism.

With a tankless water heater installation, you get a specific system that helps you save more electricity as well as water. This way you can save up to 32%-38% energy. However, the less water heater companies tend to claim 50%-60% energy, it depends on the water usage.

  1. Tankless water heaters are easy to maintain:

This is another reason that you should switch to tankless water heaters. Tank water heaters are not easy to keep clean and maintain rather than tankless water heaters. However, with tankless water heaters, you can descale your tankless system in just an hour via its maintenance valve. Just close the cold water valves to protect the cold water from rolling in. You can use 5 gallons of white vinegar to cleanse the chemical out of the system. You can also use chemical cleaning solutions but it would hinder the drinking water’s safety. This is why white vinegar is preferred instead of chemicals.

  1. Tankless water heaters raise the resale value of the house:

One of the reasons why people don’t buy or install tankless water heater is because it’s an expensive process.
