  • Tankless water heaters (gas & electric) – these heaters do not have a storage tank. Instead, they use an electric or gas element to heat the water as it enters the home through pipes
  • Point-of-use water heaters – they provide hot water where you need it – at specific locations within a home, such as a kitchen sink or shower
  • Smart water heaters – use smart technology, and you can control them remotely using a phone. Many models also include energy-saving features that help reduce your utility bill each month
  • Under sink water heaters – fits right under your sink and provide hot water instantly. It preheats water when it passes through a pipes and stores a small amount of hot water
  • Solar Heaters – These units harness the power of the sun to provide hot water for your entire household without using any electricity

Factors to Consider for a New Water Heater

Here are some factors that affect the cost of water heater installation:

  • Type and brand of water heater – The type of water heater you choose will affect your installation costs significantly. For instance, tankless water heaters are costlier than storage tank types because they require additional wiring and piping components that add up in price quickly. However, they use less energy than traditional storage tanks since they heat water as it passes through them rather than storing hot water in one location until it is needed
  • Basic installation – If all you want is basic installation services and no other upgrades, you can expect to pay less on labor
  •  Permit charges per state – Permit charges may vary from state-to-state, so if you move from one location to another, you may be required to pay more in permit fees. On average, permit fees range from $100 to $500
  • Additional labor costs – Labor costs can vary depending on the work needed to install your new water heater. In addition to replacing the water heater unit, you might need professional help with other related tasks such as relocating the fuel line or installing electrical connections. These tasks can increase your overall project cost significantly
  •  Location of the water heater – the location of your water heater can significantly impact its cost. For example, if you’re installing a tankless hot water system, you’ll need to install it in an accessible location to connect to your main water supply line. Otherwise, the entire installation process will be more expensive than usual
